Under the auspices of the American College of Cardiology Foundation (ACCF) and the American Society of Nuclear Cardiology (ASNC), an appropriateness review was conducted for radionuclide cardiovascular imaging (RNI), specifically gated single-photon emission computed tomography myocardial perfusion imaging (SPECT MPI). The review assessed the risks and benefits of the imaging test for several indications or clinical scenarios and scored them based on a scale of 1 to 9, where the upper range (7 to 9) implies that the test is generally acceptable and is a reasonable approach, and the lower range (1 to 3) implies that the test is generally not acceptable and is not a reasonable approach. The mid range (4 to 6) implies that the test may be generally acceptable and may be a reasonable approach for the indication. The indications for this review were primarily drawn from existing clinical practice guidelines and modified based on discussion by the ACCF Appropriateness Criteria Working Group and the Technical Panel members who rated the indications. The method for this review was based on the RAND/UCLA approach for evaluating appropriateness, which blends scientific evidence and practice experience. A modified Delphi technique was used to obtain first- and second-round ratings of 52 clinical indications. The ratings were done by a Technical Panel with diverse membership, including nuclear cardiologists, referring physicians (including an echocardiographer), health services researchers, and a payer (chief medical officer). These results are expected to have a significant impact on physician decision making and performance, reimbursement policy, and future research directions. Periodic assessment and updating of criteria will be undertaken as needed. [ABSTRACT FROM AUTHOR]

Importance: Historically, women with aortic stenosis have experienced worse outcomes and inadequate recognition compared to men, being both underdiagnosed and undertreated, while also facing underrepresentation in clinical trials., Objective: To determine whether women with small aortic annuli undergoing transcatheter aortic valve replacement have better clinical and hemodynamic outcomes with a self-expanding valve (SEV) or balloon-expandable valve (BEV)., Design, Setting, Participants: The Small Annuli Randomized to Evolut or SAPIEN Trial (SMART) was a large-scale randomized clinical trial focusing on patients with small aortic annuli undergoing transcatheter aortic valve replacement, randomized to receive SEVs or BEVs and included 716 patients treated at 83 centers in Canada, Europe, Israel, and the US from April 2021 to October 2022. This prespecified secondary analysis reports clinical and hemodynamic findings for all 621 women enrolled in SMART. Data for this report were analyzed from February to April 2024., Interventions: Transcatheter aortic valve replacement with an SEV or a BEV., Main Outcomes and Measures: The composite coprimary clinical end point comprised death, disabling stroke, or heart failure-related rehospitalization. The coprimary valve function end point was the incidence of bioprosthetic valve dysfunction, both assessed through 12 months. Secondary end points included the incidence of moderate or severe prosthesis-patient mismatch., Results: A total of 621 women (mean [SD] age, 80.2 [6.2] years; 312 randomized to the SEV group and 309 to the BEV group) were included in the present analysis. At 12 months, there were no significant differences in the coprimary clinical end point between the SEV and BEV groups (9.4% vs 11.8%, absolute risk difference -2.3%; 95% CI -7.2 to 2.5, P = .35). However, SEV implantation was associated with less bioprosthetic valve dysfunction (8.4% vs 41.8%; absolute risk difference, -33.4%; 95% CI, -40.4 to -26.4; P < .001). SEV implantation resulted in lower aortic valve gradients and larger effective orifice areas at 30 days and 12 months and less mild or greater aortic regurgitation at 12 months compared to BEV implantation. Prosthesis-patient mismatch was significantly lower with SEVs, regardless of the definition used and adjustment for body mass index. Use of SEVs was associated with better quality of life outcomes as assessed by the Valve Academic Research Consortium-3 ordinal quality of life measure., Conclusions and Relevance: Among women with severe symptomatic aortic stenosis and small aortic annuli undergoing transcatheter aortic valve replacement, the use of SEVs, compared to BEVs, resulted in similar clinical outcomes and a markedly reduced incidence of bioprosthetic valve dysfunction through 12 months, including a lower risk of prosthesis-patient mismatch and better 12-month quality of life., Trial Registration: ClinicalTrials.gov Identifier: NCT04722250.

Background: Aortic valve replacement (AVR) is indicated in patients with severe aortic regurgitation (AR); however, certain clinical factors may identify patients with less-than-severe AR at high mortality risk if untreated., Objectives: The authors sought to characterize key associations with mortality across the spectrum of AR in patients not treated with AVR from a large, contemporary database., Methods: We analyzed patients >18 years of age with documented AR assessment in a deidentified real-world data set from 27 U.S. institutions with appropriate permissions (egnite Database, egnite, Inc). Diagnosed AR severity was extracted from echocardiographic reports using a natural language processing-based algorithm. Cox multivariable analysis modeled the impact of key factors on untreated mortality according to AR severity., Results: In total, 81,378 patients were included for analysis. Hazard ratios for mortality were 1.26 (95% CI: 1.18-1.35) and 2.37 (95% CI: 1.96-2.87) for moderate and severe AR, respectively. Other significant associations included left ventricular (LV) ejection fraction ≤55% (1.09 [95% CI: 1.02-1.15]), LV dilation (1.34 [95% CI: 1.21-1.48]), left atrial dilation (1.09 [95% CI: 1.03-1.16]), atrial fibrillation (1.11 [1.04-1.17]), and elevated B-type natriuretic peptide/N-terminal pro-B-type natriuretic peptide (1.71 [95% CI: 1.60-1.84]). Modeled mortality risk increased with the presence of these key factors both alone and in combination., Conclusions: In patients with untreated AR, LV remodeling, left atrial remodeling, and other markers of cardiac damage are associated with substantial mortality risk, both for severe and moderate AR. Further study is needed to determine whether AVR is warranted in patients with less-than-severe AR with at-risk factors., Competing Interests: Funding for this work was provided by 10.13039/100019998JenaValve Technology, Inc.

Background: Data using real-world assessments of aortic regurgitation (AR) severity to identify rates of Heart Valve Team evaluation and aortic valve replacement (AVR), as well as mortality among untreated patients, are lacking. The present study assessed these trends in care and outcomes for real-world patients with documented AR., Methods: Using a deidentified data set (January 2018-March 2023) representing 1,002,853 patients >18 years of age from 25 US institutions participating in the egnite Database (egnite, Inc.) with appropriate permissions, patients were classified by AR severity in echocardiographic reports. Rates of evaluation by the Heart Valve Team, AVR, and all-cause mortality without AVR were examined using Kaplan-Meier estimates and compared using the log-rank test., Results: Within the data set, 845,113 patients had AR severity documented. For moderate-to-severe or severe AR, respectively, 2-year rates (95% confidence interval) of evaluation by the Heart Valve Team (43.5% [41.7%-45.3%] and 65.4% [63.3%-67.4%]) and AVR (19.4% [17.6%-21.1%] and 46.5% [44.2%-48.8%]) were low. Mortality at 2 years without AVR increased with greater AR severity, up to 20.7% for severe AR (p < 0.001). In exploratory analyses, 2-year mortality for untreated patients with left ventricular end-systolic dimension index > 25 mm/m 2 was similar for moderate (34.3% [29.2%-39.1%]) and severe (37.2% [24.9%-47.5%]) AR., Conclusions: Moderate or greater AR is associated with poor clinical outcomes among untreated patients at 2 years. Rates of Heart Valve Team evaluation and AVR were low for those with moderate or greater AR, suggesting that earlier referral to the Heart Valve Team could be beneficial., (© 2024 The Author(s).

Background: Patients with severe aortic stenosis and a small aortic annulus are at risk for impaired valvular hemodynamic performance and associated adverse cardiovascular clinical outcomes after transcatheter aortic-valve replacement (TAVR)., Methods: We randomly assigned patients with symptomatic severe aortic stenosis and an aortic-valve annulus area of 430 mm 2 or less in a 1:1 ratio to undergo TAVR with either a self-expanding supraannular valve or a balloon-expandable valve. The coprimary end points, each assessed through 12 months, were a composite of death, disabling stroke, or rehospitalization for heart failure (tested for noninferiority) and a composite end point measuring bioprosthetic-valve dysfunction (tested for superiority)., Results: A total of 716 patients were treated at 83 sites in 13 countries (mean age, 80 years; 87% women; mean Society of Thoracic Surgeons Predicted Risk of Mortality, 3.3%). The Kaplan-Meier estimate of the percentage of patients who died, had a disabling stroke, or were rehospitalized for heart failure through 12 months was 9.4% with the self-expanding valve and 10.6% with the balloon-expandable valve (difference, -1.2 percentage points; 90% confidence interval [CI], -4.9 to 2.5; P<0.001 for noninferiority). The Kaplan-Meier estimate of the percentage of patients with bioprosthetic-valve dysfunction through 12 months was 9.4% with the self-expanding valve and 41.6% with the balloon-expandable valve (difference, -32.2 percentage points; 95% CI, -38.7 to -25.6; P<0.001 for superiority). The aortic-valve mean gradient at 12 months was 7.7 mm Hg with the self-expanding valve and 15.7 mm Hg with the balloon-expandable valve, and the corresponding values for additional secondary end points through 12 months were as follows: mean effective orifice area, 1.99 cm 2 and 1.50 cm 2 ; percentage of patients with hemodynamic structural valve dysfunction, 3.5% and 32.8%; and percentage of women with bioprosthetic-valve dysfunction, 10.2% and 43.3% (all P<0.001). Moderate or severe prosthesis-patient mismatch at 30 days was found in 11.2% of the patients in the self-expanding valve group and 35.3% of those in the balloon-expandable valve group (P<0.001). Major safety end points appeared to be similar in the two groups., Conclusions: Among patients with severe aortic stenosis and a small aortic annulus who underwent TAVR, a self-expanding supraannular valve was noninferior to a balloon-expandable valve with respect to clinical outcomes and was superior with respect to bioprosthetic-valve dysfunction through 12 months.

Background: The prognostic value of cardiac damage staging classification based on the extent of extravalvular damage has been proposed in moderate/severe aortic stenosis (AS)., Objectives: The purpose of this study was to assess the association of cardiac damage staging with mortality across the spectrum of patients with AS following aortic surgical or transcatheter aortic valve replacement (AVR)., Methods: We conducted a pooled meta-analysis of Kaplan-Meier-derived reconstructed time-to-event data from studies published through February 2023., Results: In total, 16 studies (n = 14,499) met our eligibility criteria and included 12,282 patients with symptomatic severe AS and 2,217 patients with asymptomatic severe/moderate AS. For patients with symptomatic severe AS, all-cause mortality was 24.0%, 27.7%, 38.0%, 56.3%, and 57.3% at 5 years in patients with cardiac damage stage 0, 1, 2, 3, and 4, respectively (stage 0 as reference; HR in stage 1: 1.30 [95% CI: 1.03-1.64]; P  = 0.029; stage 2: 1.74 [95% CI: 1.41-2.16]; P  < 0.001; stage 3: 2.92 [95% CI: 2.35-3.64]; P  < 0.001, and stage 4: 3.51 [95% CI: 2.79-4.41]; P  < 0.001). For patients with asymptomatic moderate/severe AS, all-cause mortality was 19.3%, 36.9%, 51.7%, and 67.8% at 8 years in patients with cardiac damage stage 0, 1, 2, and 3 to 4, respectively (HR in stage 1: 1.70 [95% CI: 1.21-2.38]; P  = 0.002; stage 2: 2.20 [95% CI: 1.60-3.02]; P  < 0.001; and stage 3 to 4: 3.90 [95% CI: 2.79-5.47]; P  < 0.001)., Conclusions: In patients undergoing AVR across the symptomatic and severity spectrum of AS, cardiac damage staging at baseline has important prognostic implications. This pooled meta-analysis in patients undergoing AVR suggests that staging of baseline cardiac damage could be considered for timing and selection of therapy in patients with moderate or severe AS to determine the need for earlier AVR or adjunctive pharmacotherapy to prevent irreversible cardiac damage and improve the long-term prognosis., Competing Interests: Mr Xander Jacquemyn was supported by the Belgian American Educational Foundation.

Background: The CLASP IID randomized trial (Edwards PASCAL TrAnScatheter Valve RePair System Pivotal Clinical Trial) demonstrated the safety and effectiveness of the PASCAL system for mitral transcatheter edge-to-edge repair (M-TEER) in patients at prohibitive surgical risk with significant symptomatic degenerative mitral regurgitation (DMR)., Objectives: This study describes the echocardiographic methods and outcomes from the CLASP IID trial and analyzes baseline variables associated with residual mitral regurgitation (MR) ≤1+., Methods: An independent echocardiographic core laboratory assessed echocardiographic parameters based on American Society of Echocardiography guidelines focusing on MR mechanism, severity, and feasibility of M-TEER. Factors associated with residual MR ≤1+ were identified using logistic regression., Results: In 180 randomized patients, baseline echocardiographic parameters were well matched between the PASCAL (n = 117) and MitraClip (n = 63) groups, with flail leaflets present in 79.2% of patients. Baseline MR was 4+ in 76.4% and 3+ in 23.6% of patients. All patients achieved MR ≤2+ at discharge. The proportion of patients with MR ≤1+ was similar in both groups at discharge but diverged at 6 months, favoring PASCAL (83.7% vs 71.2%). Overall, patients with a smaller flail gap were significantly more likely to achieve MR ≤1+ at discharge (adjusted OR: 0.70; 95% CI: 0.50-0.99). Patients treated with PASCAL and those with a smaller flail gap were significantly more likely to sustain MR ≤1+ to 6 months (adjusted OR: 2.72 and 0.76; 95% CI: 1.08-6.89 and 0.60-0.98, respectively)., Conclusions: The study used DMR-specific echocardiographic methodology for M-TEER reflecting current guidelines and advances in 3-dimensional echocardiography. Treatment with PASCAL and a smaller flail gap were significant factors in sustaining MR ≤1+ to 6 months. Results demonstrate that MR ≤1+ is an achievable benchmark for successful M-TEER.

Background: Favorable 6-month outcomes from the CLASP IID Registry (Edwards PASCAL transcatheter valve repair system pivotal clinical trial) demonstrated that mitral valve transcatheter edge-to-edge repair with the PASCAL transcatheter valve repair system is safe and beneficial for treating prohibitive surgical risk degenerative mitral regurgitation (DMR) patients with complex mitral valve anatomy., Objectives: The authors sought to assess 1-year safety, echocardiographic and clinical outcomes from the CLASP IID Registry., Methods: Patients with 3+ or 4+ DMR who were at prohibitive surgical risk, had complex mitral valve anatomy based on the MitraClip Instructions for Use, and deemed suitable for treatment with the PASCAL system were enrolled prospectively. Safety, clinical, echocardiographic, functional, and quality-of-life outcomes were assessed at 1 year. Study oversight included a central screening committee, echocardiographic core laboratory, and clinical events committee., Results: Ninety-eight patients were enrolled. One-year Kaplan-Meier (KM) estimates of freedom from composite major adverse events, all-cause mortality, and heart failure hospitalization were 83.5%, 89.3%, and 91.5%, respectively. Significant mitral regurgitation (MR) reduction was achieved at 1 year (P < 0.001 vs baseline) including 93.2% at MR ≤2+ and 57.6% at MR ≤1+ with improvements in related echocardiographic measures. NYHA functional class and Kansas City Cardiomyopathy Questionnaire score also improved significantly (P < 0.001 vs baseline)., Conclusions: At 1 year, treatment with the PASCAL system demonstrated safety and significant MR reduction, with continued improvement in clinical, echocardiographic, functional, and quality-of-life outcomes, illustrating the value of the PASCAL system in the treatment of prohibitive surgical risk patients with 3+ or 4+ DMR and complex mitral valve anatomy., Competing Interests: Funding Support and Author Disclosures Dr Smith is on the CLASP IID Trial leadership team and has received institutional grant and travel support for device evaluation from Edwards Lifesciences; has received institutional grants from Artivion; and honoraria for speaking from Artivion and Medtronic.

Secondary mitral regurgitation (SMR) in patients with heart failure (HF) is associated with significant morbidity and mortality. In recent decades, SMR has received increasing scientific attention. Advances in echocardiography, computed tomography and cardiac magnetic resonance imaging have refined our ability to diagnose, quantify and characterize SMR. Concurrently, the treatment options for this high-risk patient population have continued to evolve. Guideline-directed medical therapies including beta-blockers, angiotensin receptor-neprilysin inhibitors, mineralocorticoid receptor antagonists and sodium-glucose cotransporter-2 inhibitors target the underlying cardiomyopathy, and along with diuretics to treat pulmonary congestion, remain the cornerstone of therapy. Cardiac resynchronization therapy also reduces MR, alleviates symptoms and prolongs life in selected HF patients with SMR. While data supporting surgical mitral valve repair or replacement for SMR are limited, transcatheter edge-to-edge repair (TEER) has been demonstrated to improve survival, reduce the rate of hospitalization for heart failure, and improve functional capacity and quality-of-life in select patients with SMR who remain symptomatic despite medical therapy. Emerging transcatheter mitral valve repair and replacement technologies are undergoing investigation in TEER-eligible and TEER-ineligible patients. The optimal management of HF patients with SMR requires a multidisciplinary team of cardiologists, cardiac surgeons, imaging experts, and other organ specialists to select the best treatment approaches to improve the prognosis of these high-risk patients., (© 2023 The Author(s).)

Background: The American College of Cardiology/American Heart Association guidelines recommend the assessment and grading of severity of aortic stenosis (AS) as mild, moderate, or severe, per echocardiogram, and recommend aortic valve replacement (AVR) when the AS is severe., Objectives: The authors sought to describe mortality rates across the entire spectrum of untreated AS from a contemporary, large, real-world database., Methods: We analyzed a deidentified real-world data set including 1,669,536 echocardiographic reports (1,085,850 patients) from 24 U.S. hospitals (egnite Database, egnite). Patients >18 years of age were classified by diagnosed AS severity. Untreated mortality and treatment rates were examined with Kaplan-Meier (KM) estimates, with results compared using the log-rank test. Multivariate hazards analysis was performed to assess associations with all-cause mortality., Results: Among 595,120 patients with available AS severity assessment, the KM-estimated 4-year unadjusted, untreated, all-cause mortality associated with AS diagnosis of none, mild, mild-to-moderate, moderate, moderate-to-severe, or severe was 13.5% (95% CI: 13.3%-13.7%), 25.0% (95% CI: 23.8%-26.1%), 29.7% (95% CI: 26.8%-32.5%), 33.5% (95% CI: 31.0%-35.8%), 45.7% (95% CI: 37.4%-52.8%), and 44.9% (95% CI: 39.9%-49.6%), respectively. Results were similar when adjusted for informative censoring caused by treatment. KM-estimated 4-year observed treatment rates were 0.2% (95% CI: 0.2%-0.2%), 1.0% (95% CI: 0.7%-1.3%), 4.2% (95% CI: 2.0%-6.3%), 11.4% (95% CI: 9.5%-13.3%), 36.7% (95% CI: 31.8%-41.2%), and 60.7% (95% CI: 58.0%-63.3%), respectively. After adjustment, all degrees of AS severity were associated with increased mortality., Conclusions: Patients with AS have high mortality risk across all levels of untreated AS severity. Aortic valve replacement rates remain low for patients with severe AS, suggesting that more research is needed to understand barriers to diagnosis and appropriate approach and timing for aortic valve replacement., Competing Interests: Funding Support and Author Disclosures Dr Généreux has served as a consultant for, an advisor for, and received speaker fees from Abbott Vascular, Abiomed, Edwards Lifesciences, and Medtronic; has served as a consultant for Boston Scientific, GE Healthcare, iRhythm Technologies, OpSens, Siemens, and Teleflex; has served as a consultant for and PI of the Eclipse Trial for Cardiovascular System Inc; has served as a proctor for, received research grants from, and served as PI for the EARLY-TAVR and PROGRESS trials for Edwards Lifesciences; has equity in and served as a consultant for Pi-Cardia, Puzzle Medical, Saranas, and Soundbite Medical Inc; has served as a consultant for and received speaker fees from Shockwave; has served as a consultant for and PI of the ALTA Valve Feasibility study for 4C Medical; and has served as a consultant and advisor for egnite, Inc.

Background: The CLASP IID (Edwards PASCAL TrAnScatheter Valve RePair System Pivotal Clinical) trial is the first randomized controlled trial comparing the PASCAL system and the MitraClip system in prohibitive risk patients with significant symptomatic degenerative mitral regurgitation (DMR)., Objectives: The study sought to report primary and secondary endpoints and 1-year outcomes for the full cohort of the CLASP IID trial., Methods: Prohibitive-risk patients with 3+/4+ DMR were randomized 2:1 (PASCAL:MitraClip). One-year assessments included secondary effectiveness endpoints (mitral regurgitation [MR] ≤2+ and MR ≤1+), and clinical, echocardiographic, functional, and quality-of-life outcomes. Primary safety (30-day composite major adverse events [MAE]) and effectiveness (6-month MR ≤2+) endpoints were assessed for the full cohort., Results: Three hundred patients were randomized (PASCAL: n = 204; MitraClip: n = 96). At 1 year, differences in survival, freedom from heart failure hospitalization, and MAE were nonsignificant (P > 0.05 for all). Noninferiority of the PASCAL system compared with the MitraClip system persisted for the primary endpoints in the full cohort (For PASCAL vs MitraClip, the 30-day MAE rates were 4.6% vs 5.4% with a rate difference of -0.8% and 95% upper confidence bound of 4.6%. The 6-month MR≤2+ rates were 97.9% vs 95.7% with a rate difference of 2.2% and 95% lower confidence bound (LCB) of -2.5%, for, respectively). Noninferiority was met for the secondary effectiveness endpoints at 1 year (MR≤2+ rates for PASCAL vs MitraClip were 95.8% vs 93.8% with a rate difference of 2.1% and 95% LCB of -4.1%. The MR≤1+ rates were 77.1% vs 71.3% with a rate difference of 5.8% and 95% LCB of -5.3%, respectively). Significant improvements in functional classification and quality of life were sustained in both groups (P <0.05 for all vs baseline)., Conclusions: The CLASP IID trial full cohort met primary and secondary noninferiority endpoints, and at 1 year, the PASCAL system demonstrated high survival, significant MR reduction, and sustained improvements in functional and quality-of-life outcomes. Results affirm the PASCAL system as a beneficial therapy for prohibitive-surgical-risk patients with significant symptomatic DMR., Competing Interests: Funding Support and Author Disclosures The CLASP IID trial is funded by Edwards Lifesciences.

Although it is assumed that more severe MR is associated with a greater burden of symptoms and lower exercise capacity, the relationship between symptoms, exercise capacity, and mitral regurgitant severity has not been well studied. We prospectively studied 67 (63 ± 11 years, 72% male) patients with at least mild degenerative MR and left ventricular ejection fraction ≥ 50% who underwent stress echocardiography, CMR, and evaluation with the Kansas City Cardiomyopathy questionnaire (KCCQ). Symptoms and exercise capacity were evaluated in the context of MR severity. Patients reporting dyspnea had lower KCCQ symptom scores (79 ± 23 vs. 96 ± 9, p = 0.01) and achieved lower percentage of age and gender predicted METs (114 ± 37 vs. 152 ± 43%, p < 0.001) compared to those without dyspnea. There was no significant difference in MR volume between those with vs. without dyspnea by CMR (43 ± 26 ml vs. 51 ± 28 ml, p = 0.3) or echocardiography (64 ± 28 vs. 73 ± 41ml, p = 0.4). Those with severe MR by CMR had similar KCCQ symptom scores (96 ± 10 vs. 89 ± 17, p = 0.04) and percentage of age and gender predicted METs (148 ± 42 vs. 133 ± 47%, p = 0.2) to those without severe MR. Those with severe MR by echocardiography had similar KCCQ symptom score (93 ± 15 vs. 89 ± 16, p = 0.3) and percentage of age and gender predicted METs (138 ± 43 vs. 153 ± 46%, p = 0.2) to those without severe MR. Patients with degenerative MR assessed by CMR and stress echocardiography, there was no relationship between MR severity and either symptoms or exercise capacity. These findings highlight the disconnect between symptoms and the severity of MR and challenge the assumption that correcting MR can be counted on to improve symptom status in patients with degenerative MR., (© 2023.

Background: Depression and cognitive dysfunction (CD) are not routinely screened for in patients before transcatheter aortic valve replacement (TAVR) and their association with postprocedural outcomes is poorly understood. The objectives of this study are to determine the prevalence of depression and CD in patients with aortic stenosis undergoing TAVR and evaluate their association with mortality and quality of life., Methods: We analyzed a prospective, multicenter TAVR registry that systematically screened patients for preexisting depression and CD with the Patient Health Questionnaire-2 and Mini-Cog, respectively. The associations with mortality were assessed with Cox proportional hazard models and quality of life (Kansas City Cardiomyopathy Questionnaire and EuroQol visual analogue scale) were evaluated using multivariable ordinal regression models., Results: A total of 884 patients were included; median follow-up was 2.88 years (interquartile range=1.2-3.7). At baseline, depression was observed in 19.6% and CD in 31.8%. In separate models, after adjustment, depression (HR, 1.45 [95% CI, 1.13-1.86]; P <0.01) and CD (HR, 1.27 [95% CI, 1.02-1.59]; P =0.04) were each associated with increased mortality. Combining depression and CD into a single model, mortality was greatest among those with both depression and CD (n=62; HR, 2.06 [CI, 1.44-2.96]; P <0.01). After adjustment, depression was associated with 6.6 (0.3-13.6) points lower on the Kansas City Cardiomyopathy Questionnaire 1-year post-TAVR and 6.7 (0.5-12.7) points lower on the EuroQol visual analogue scale. CD was only associated with lower EuroQol visual analogue scale., Conclusions: Depression and CD are common in patients that undergo TAVR and are associated with increased mortality and worse quality of life. Depression may be a modifiable therapeutic target to improve outcomes after TAVR., Competing Interests: Disclosures Dr Fearon receives institutional research support from Edwards, Abbott, Boston Scientific, and Medtronic.

Purpose of Review: This review summarizes the current management of patients with newly diagnosed aortic stenosis., Recent Findings: Recent developments include detection of early myocardial dysfunction using serum B-type natriuretic peptide levels and global longitudinal strain, as well as ongoing trials of transcatheter aortic valve replacement in asymptomatic patients and patients with moderate aortic stenosis complicated by symptoms or left ventricular systolic dysfunction. Given the high mortality associated with severe symptomatic aortic stenosis, all symptomatic patients should be referred for aortic valve replacement. Asymptomatic patients with left ventricular systolic dysfunction, abnormal exercise stress test, high degree of stenosis, rapid disease progression, or elevated serum B-type natriuretic peptide level may also have an indication for valve replacement, based on established criteria. The progress in management of severe aortic stenosis has been in the direction of earlier detection and earlier valve replacement., (© 2023.

Background: The extent of extravalvular cardiac damage is associated with increased risk of adverse events among patients with severe aortic stenosis undergoing aortic valve replacement (AVR)., Objectives: The goal was to describe the association of cardiac damage on health status before and after AVR., Methods: Patients from the PARTNER (Placement of Aortic Transcatheter Valves) 2 and 3 trials were pooled and classified by echocardiographic cardiac damage stage at baseline and 1 year as previously described (stage 0-4). We examined the association between baseline cardiac damage and 1-year health status (assessed by the Kansas City Cardiomyopathy Questionnaire Overall Score [KCCQ-OS])., Results: Among 1,974 patients (794 surgical AVR, 1,180 transcatheter AVR), the extent of cardiac damage at baseline was associated with lower KCCQ scores both at baseline and at 1 year after AVR (P < 0.0001) and with increased rates of a poor outcome (death, KCCQ-OS <60, or a decrease in KCCQ-OS of ≥10 points) at 1 year (stages 0-4: 10.6% vs 19.6% vs 29.0% vs 44.7% vs 39.8%; P < 0.0001). In a multivariable model, each 1-stage increase in baseline cardiac damage was associated with a 24% increase in the odds of a poor outcome (95% CI: 9%-41%; P = 0.001). Change in stage of cardiac damage at 1 year after AVR was associated with the extent of improvement in KCCQ-OS over the same period (mean change in 1-year KCCQ-OS: improvement of ≥1 stage +26.8 [95% CI: 24.2-29.4] vs no change +21.4 [95% CI: 20.0-22.7] vs deterioration of ≥1 stage +17.5 [95% CI: 15.4-19.5]; P < 0.0001)., Conclusions: The extent of cardiac damage before AVR has an important impact on health status outcomes, both cross-sectionally and after AVR.

Background: Mitral valve transcatheter edge-to-edge repair is safe and effective in treating degenerative mitral regurgitation (DMR) patients at prohibitive surgical risk, but outcomes in complex mitral valve anatomy patients vary., Objectives: The PASCAL IID registry assessed safety, echocardiographic, and clinical outcomes with the PASCAL system in prohibitive risk patients with significant symptomatic DMR and complex mitral valve anatomy., Methods: Patients in the prospective, multicenter, single-arm registry had 3+ or 4+ DMR, were at prohibitive surgical risk, presented with complex anatomic features based on the MitraClip instructions for use, and were deemed suitable for the PASCAL system by a central screening committee. Enrolled patients were treated with the PASCAL system. Safety, effectiveness, and functional and quality-of-life outcomes were assessed. Study oversight also included an echocardiographic core laboratory and clinical events committee., Results: The study enrolled 98 patients (37.2% ≥2 independent significant jets, 15.0% severe bileaflet/multi scallop prolapse, 13.3% mitral valve orifice area <4.0 cm 2 , and 10.6% large flail gap and/or large flail width). The implant success rate was 92.9%. The 30-day composite major adverse event rate was 11.2%. At 6 months, 92.4% patients achieved MR ≤2+ and 56.1% achieved MR ≤1+ (P < 0.001 vs baseline). The Kaplan-Meier estimates for survival, freedom from major adverse events, and heart failure hospitalization at 6 months were 93.7%, 85.6%, and 92.6%, respectively. Patients experienced significant symptomatic improvement compared with baseline (P < 0.001)., Conclusions: The outcomes of the PASCAL IID registry establish the PASCAL system as a useful therapy for prohibitive surgical risk DMR patients with complex mitral valve anatomy.

Background: Severe symptomatic degenerative mitral regurgitation (DMR) has a poor prognosis in the absence of treatment, and new transcatheter options are emerging., Objectives: The CLASP IID (Edwards PASCAL Transcatheter Valve Repair System Pivotal Clinical Trial) randomized trial (NCT03706833) is the first to evaluate the safety and effectiveness of the PASCAL system compared with the MitraClip system in patients with significant symptomatic DMR. This report presents the primary safety and effectiveness endpoints for the trial., Methods: Patients with 3+ or 4+ DMR at prohibitive surgical risk were assessed by a central screening committee and randomized 2:1 (PASCAL:MitraClip). Study oversight also included an echocardiography core laboratory and a clinical events committee. The primary safety endpoint was the composite major adverse event rate at 30 days. The primary effectiveness endpoint was the proportion of patients with mitral regurgitation (MR) ≤2+ at 6 months., Results: A prespecified interim analysis in 180 patients demonstrated noninferiority of the PASCAL system vs the MitraClip system for the primary safety and effectiveness endpoints of major adverse event rate (3.4% vs 4.8%) and MR ≤2+ (96.5% vs 96.8%), respectively. Functional and quality-of-life outcomes significantly improved in both groups (P < 0.05). The proportion of patients with MR ≤1+ was durable in the PASCAL group from discharge to 6 months (PASCAL, 87.2% and 83.7% [P = 0.317 vs discharge]; MitraClip, 88.5% and 71.2% [P = 0.003 vs discharge])., Conclusions: The CLASP IID trial demonstrated safety and effectiveness of the PASCAL system and met noninferiority endpoints, expanding transcatheter treatment options for prohibitive surgical risk patients with significant symptomatic DMR., Competing Interests: Funding Support and Author Disclosures The CLASP IID trial is funded by Edwards Lifesciences.

Importance: Internal medicine residents' professional development preferences were discordant with their perceptions of cardiology in a survey circulated a decade ago; no contemporary data exist. This information is important for effective recruitment and retention of a highly talented and diverse future cardiology workforce., Objective: To identify residents' professional development preferences and cardiology perceptions, in relation to specialty choice, and compare the findings with those from a decade prior., Design, Setting, and Participants: The original survey from the 2010 study was updated and sent to US internal medicine programs. Respondents (ie, internal medicine residents) rated 38 professional development preferences and 20 cardiology perceptions. Data were collected in 2020 and compared with survey results from the prior 2010 study. Multivariable models were created for specialty choice using scaled independent variables dichotomized using the top 2 options; categorical variables were recoded into binary variables for analysis., Main Outcomes and Measures: Multivariable models were used to determine the association of demographic characterisitcs and survey responses with prospective career choice. Responses were examined by total group, by gender, by self-reported consideration of entering cardiology as a profession, and by comparison with a decade prior both as a group and by gender., Results: A total of 840 residents (mean [SD] age, 29.24 [2.82] years; 49.8% male; 55.4% White) completed the survey. The survey incorporated a 5-point Likert scale of 1 (not important) to 5 (extremely important) for some of the questions, with additional questions on demographic characteristics. The most important professional development preferences by descending Likert score were as follows: positive role models (4.56), stimulating career (3.81), and family friendly (3.78). The cardiology perception statements with the highest agreement were as follows: interferes with family life during training (3.93) and having met positive role models or having positive views of cardiovascular disease as a topic (3.85). Multivariable analysis yielded a 22-element model predicting cardiology as career choice. Compared with the 2010 survey, the findings of this survey indicated increased importance of work-life balance components for both male and female residents, with a greater change in male residents. Contemporary residents were more likely than their predecessors to agree with negative perceptions of cardiology., Conclusions and Relevance: This survey study found that both male and female residents place a high value on support for optimal work-life balance; these preferences have intensified over the past decade and factor into career choice. Negative perceptions of cardiology persist and, in some aspects, are worsening. Improving the culture of cardiology may make this specialty a more attractive career choice for all.

Background: The impact of aortic valve replacement (AVR) on progression/regression of extravalvular cardiac damage and its association with subsequent prognosis is unknown., Objectives: The purpose of this study was to describe the evolution of cardiac damage post-AVR and its association with outcomes., Methods: Patients undergoing transcatheter or surgical AVR from the PARTNER (Placement of Aortic Transcatheter Valves) 2 and 3 trials were pooled and classified by cardiac damage stage at baseline and 1 year (stage 0, no damage; stage 1, left ventricular damage; stage 2, left atrial or mitral valve damage; stage 3, pulmonary vasculature or tricuspid valve damage; and stage 4, right ventricular damage). Proportional hazards models determined association between change in cardiac damage post-AVR and 2-year outcomes., Results: Among 1,974 patients, 121 (6.1%) were stage 0, 287 (14.5%) stage 1, 1,014 (51.4%) stage 2, 412 (20.9%) stage 3, and 140 (7.1%) stage 4 pre-AVR. Two-year mortality was associated with extent of cardiac damage at baseline and 1 year. Compared with baseline, cardiac damage improved in ∼15%, remained unchanged in ∼60%, and worsened in ∼25% of patients at 1 year. The 1-year change in cardiac damage stage was independently associated with mortality (adjusted HR for improvement: 0.49; no change: 1.00; worsening: 1.95; P = 0.023) and composite of death or heart failure hospitalization (adjusted HR for improvement: 0.60; no change: 1.00; worsening: 2.25; P < 0.001) at 2 years., Conclusions: In patients undergoing AVR, extent of extravalvular cardiac damage at baseline and its change at 1 year have important prognostic implications. These findings suggest that earlier detection of aortic stenosis and intervention before development of irreversible cardiac damage may improve global cardiac function and prognosis.

Background: We aim to establish the degree of agreement related to gradient measurement during transcatheter aortic valve replacement (TAVR) between the OpSens OptoWire III and its new proprietary TAVR algorithm and hemodynamic value derived by catheterization and echocardiogram (transthoracic echocardiogram and transesophageal echocardiogram)., Methods: The current study was a prospective, single-arm, single-center study. All subjects underwent hemodynamic assessment before and after TAVR using standard hemodynamic assessment using 2 pigtails, transthoracic echocardiogram, transesophageal echocardiogram, and the OpSens OptoWire III. The primary end point was the final post-TAVR mean gradient correlation between OpSens OptoWire III and hemodynamic values derived by catheterization., Results: Between July 2021 and September 2021, 20 patients were enrolled. The median age was 79 [6.5] years, and 9 (45%) patients were female. The mean gradient before TAVR derived by 2-pigtail technique and the mean gradient using the OpSens OptoWire III were similar (35 ± 14 mm Hg vs 35 ± 14 mm Hg, P = 1.00), with an absolute mean difference of 2.2 ± 3.5 mm Hg and a strong correlation ( r = 0.96, P < .0001). After TAVR, the mean gradient derived by 2-pigtail technique and the mean gradient using the OpSens OptoWire III were similar (2.2 ± 3.5 vs 2.8 ± 2.7, P = .16), with an absolute mean difference of 1.2 ± 1.3 mm Hg and a strong correlation ( r = 0.89, P < .0001)., Conclusions: Hemodynamic assessment derived by the OpSens OptoWire III wire and its new TAVR algorithm demonstrated excellent correlation with measurements derived by 2 pigtails both before and after TAVR. Integration of this new technology within a dedicated TAVR wire with live hemodynamic assessment could bring meaningful value to TAVR operators., Competing Interests: Dr Philippe Genereux is a consulat for Abbott Vascular, Abiomed, BioTrace Medical, Boston Scientific, CARANX Medical, Cardiovascular System Inc, Edwards LifeSciences, GE Healthcare, iRhythm Technologies, Medtronic, OpSens, Pi-Cardia, Puzzle Medical, Saranas, Shockwave, Siemens, Soundbite Medical Inc, Teleflex, and 4C Medical; is an advisor for Abbott Vascular, Abiomed, BioTrace Medical, Edwards LifeSciences, and Medtronic; receives speaker fees from Abbott Vascular, Abiomed, BioTrace Medical, Edwards LifeSciences, Medtronic, and Shockwave; is a primary investigator of the ECLIPSE trial in Cardiovascular System Inc; is a proctor for Edwards LifeSciences; receives research grant from 10.13039/100006520Edwards LifeSciences; is a primary investigator of the PI EARLY-TAVR and PI PROGRESS trials of Edwards LifeSciences; has equity in Soundbite Medical Inc; and is a primary investigator of the PI Feasibility study of 4C Medical.

Objectives: The purpose of this study was to compare the American Society of Echocardiography (ASE) algorithm for assessing mitral regurgitation (MR) to cardiac magnetic resonance (CMR) and left ventricular (LV) remodeling following mitral intervention., Background: The ASE recommends integrating multiple echocardiographic parameters for assessing MR. The ASE guidelines include an algorithm that weighs the parameters and highlights those considered indicative of definitely mild or definitely severe MR., Methods: We prospectively enrolled 152 (age 62 ± 13 years; 59% male) patients with degenerative MR who underwent ASE algorithm-guided echocardiographic and CMR grading of MR severity. Using the ASE algorithm, patients were graded as definitely mild, grade I, grade II, grade III, grade IV, or definitely severe MR. CMR MR volume was graded as mild (<30 mL), grade II moderate (30-44 mL), grade III moderate (45-59 mL), or severe (≥60 mL). A subgroup of 63 patients underwent successful mitral intervention, of whom 48 had postintervention CMR., Results: Only 52% of patients with definitely severe MR by the ASE algorithm had severe MR by CMR, and 10% had mild MR by CMR. There was an increase in post mitral intervention LV reverse remodeling with worsening MR severity using CMR (P < 0.0001) but not the ASE algorithm (P = 0.07). Severe MR by CMR was an independent predictor of post mitral intervention LV reverse remodeling and definitely severe MR by the ASE algorithm was not., Conclusions: In patients with degenerative MR, agreement between CMR and the ASE algorithm was suboptimal. Severe MR by CMR was an independent predictor of post mitral intervention LV reverse remodeling, whereas definitely severe MR by the ASE algorithm was not. These findings suggest an important role for CMR in surgical decision making in degenerative MR.

Background: Echocardiography guidelines note that a flail leaflet is a specific criterion for severe mitral regurgitation (MR) and that regurgitant severity is underestimated in wall-impinging jets (Coandă effect). Both findings are often considered to be pathognomonic of severe MR., Objectives: In this study, the authors sought to determine the association of flail leaflet and Coandă effect with MR severity quantified by means of cardiac magnetic resonance (CMR)., Methods: The authors enrolled 158 consecutive patients with primary MR according to echocardiography and CMR. The presence of a flail leaflet or Coandă was determined for each patient. CMR regurgitant volume (RV) and regurgitant fraction (RF) were quantified for all patients., Results: There were 55 patients (35%) with a flail leaflet, 52 (33%) with Coandă, and 22 (14%) with a flail leaflet and Coandă. The mean CMR mitral RV and RF progressively increased in patients without a Coandă or flail, a Coandă, a flail, or a Coandă and a flail (RV: 28 ± 21 mL vs 43 ± 23 mL vs 58 ± 29 mL vs 64 ± 25 mL [P < 0.001]; RF: 25% ± 16% vs 34% ± 14% vs 41% ± 12% vs 45% ± 12% [P < 0.001]). With the use of CMR RV, 35%, 46%, and 59% of patients had severe MR with the presence of a Coandă, flail leaflet, or both, respectively. With the use of CMR RF, 25%, 31%, and 40% of patients had severe MR with the presence of a Coandă, flail leaflet, or both, respectively., Conclusions: While the presence of a flail leaflet and Coandă effect on echocardiography are associated with higher regurgitant volumes and fractions, they are frequently not associated with severe MR as assessed by means of CMR.

Limited data suggests ultrasound enhancing agent (UEA) use is associated with changes in clinical management and lower mortality in intensive care unit (ICU) patients. We conducted a retrospective observational study to determine if contrast echocardiography (vs non-contrast echocardiography) is associated with differences in length of stay (LOS) and subsequent resource utilization in the ICU setting. The Premier Healthcare Database (Charlotte, NC) was analyzed to identify patients receiving Definity vs. no use of contrast during the initial rest transthoracic echocardiogram (TTE) in an ICU setting. The primary outcomes of interest were subsequent TTE and transesophageal echocardiography (TEE) during the index hospitalization, and ICU LOS. Propensity scoring was used to statistically model treatment selection to minimize selection bias. A total of 1,538,864 patients from 773 hospitals were identified as undergoing resting TTE in the ICU with use of DEFINITY in 51,141 (3.3%) patients and no contrast agent use in 1,487,723 (96.7%) patients. After adjusting for patient, clinical, and hospital characteristics, patients in the Definity cohort were less likely to undergo a subsequent TTE or TEE as compared to those in the no contrast cohort (odds ratio = 0.704 for TTE, odds ratio = 0.841 for TEE; p < 0.0001 for both). Adjusted mean ICU LOS for the Definity cohort was shorter than that of the no contrast cohort (4.59 vs 4.15 days, p < 0.0001). In conclusion, Definity-enhanced echocardiography in the ICU setting (in comparison with non-contrast TTE) is associated with lower rates of subsequent TTE and TEE during the index hospitalization, and shorter ICU LOS., (Copyright © 2021 Elsevier Inc.

Aims: Impaired physical function is common in patients undergoing transcatheter aortic valve replacement (TAVR) and associated with worse outcomes. Participation in centre-based cardiac rehabilitation (CR) after cardiovascular procedures is sub-optimal. We aimed to test a home-based mobile health exercise intervention as an alternative or complementary approach., Methods and Results: At five centres, after a run-in period, eligible individuals treated with TAVR were randomized 1:1 at their 1-month post-TAVR visit to an intervention group [activity monitor (AM) with personalized daily step goal and resistance exercises] or a control group for 6 weeks. Among 50 participants, average age was 76 years, 34% were female, average STS score was 2.91.8, and 40% had Short Physical Performance Battery (SPPB) 9. Daily compliance with wearing the AM and performing exercises averaged 8590%. In the intention to treat population, there was no evidence that the intervention improved the co-primary endpoints: daily steps +769 (95% CI 244 to +1783); SPPB +0.68 (0.27 to 1.53); and Kansas City Cardiomyopathy Questionnaire 1.7 (9.1 to 7.1). The intervention did improve secondary physical activity parameters, including moderate-to-intense daily active minutes ( P <0.05). In a pre-specified analysis including participants who did not participate in CR ( n =30), the intervention improved several measures of physical activity: +1730 (1003360) daily steps; +66 (28105) daily active minutes; +53 (2780) moderate-to-intense active minutes; and 157 (265 to 50) sedentary minutes., Conclusion: Among selected participants treated with TAVR, this study did not provide evidence that a pragmatic home-based mobile health exercise intervention improved daily steps, physical performance or QoL for the overall cohort. However, the intervention did improve several measures of daily activity, particularly among individuals not participating in CR., Trial Registry: Clinicaltrials.gov NCT03270124., (The Author(s) 2021.

The American College of Cardiology (ACC) collaborated with the American Heart Association, American Society of Echocardiography, Heart Rhythm Society, International Society for Adult Congenital Heart Disease, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and the Society of Pediatric Echocardiography to develop Appropriate Use Criteria (AUC) for multimodality imaging during the follow-up care of patients with congenital heart disease (CHD). This is the first AUC to address cardiac imaging in adult and pediatric patients with established CHD. A number of common patient scenarios (also termed "indications") and associated assumptions and definitions were developed using guidelines, clinical trial data, and expert opinion in the field of CHD. 1 The indications relate primarily to evaluation before and after cardiac surgery or catheter-based intervention, and they address routine surveillance as well as evaluation of new-onset signs or symptoms. The writing group developed 324 clinical indications, which they separated into 19 tables according to the type of cardiac lesion. Noninvasive cardiac imaging modalities that could potentially be used for these indications were incorporated into the tables, resulting in a total of 1,035 unique scenarios. These scenarios were presented to a separate, independent panel for rating, with each being scored on a scale of 1 to 9, with 1 to 3 categorized as "Rarely Appropriate," 4 to 6 as "May Be Appropriate," and 7 to 9 as "Appropriate." Forty-four percent of the scenarios were rated as Appropriate, 39% as May Be Appropriate, and 17% as Rarely Appropriate. This AUC document will provide guidance to clinicians in the care of patients with established CHD by identifying the reasonable imaging modality options available for evaluation and surveillance of such patients. It will also serve as an educational and quality improvement tool to identify patterns of care and reduce the number of Rarely Appropriate tests in clinical practice., (Copyright © 2020 The American College of Cardiology Foundation.

Purpose of Review: To describe the key role of the structural imager/interventional echocardiographer in transcatheter mitral valve therapies, particularly edge-to-edge repair. In addition, we review important recent advances in structural imaging and briefly describe several novel devices for transcatheter mitral valve repair., Recent Findings: Structural imagers represent a new subspecialty in cardiology and anesthesiology with specific skillset and training requirements. Their role is particularly important in imaging-based transcatheter interventions such as edge-to-edge mitral valve repair. This therapy has increasingly been used to treat primary (degenerative) mitral regurgitation when surgical risk is prohibitive and has recently been extended to patients with secondary (functional) mitral regurgitation. As novel transcatheter therapies continue to emerge, so do new multimodality imaging technologies. Structural imagers have become an integral part of the heart team. Their role is particularly visible in transcatheter mitral procedures. Rapidly developing transcatheter therapies have helped shape this new subspecialty and spark innovation in imaging technologies.

Multimodality imaging plays a pivotal role in the evaluation and management of infective endocarditis (IE)-a condition with high morbidity and mortality. The diagnosis of IE is primarily based on the modified Duke criteria with echocardiography as the first-line imaging modality. Both transthoracic and transesophageal echocardiography delineate vegetation location and size, assess for paravalvular extension of infection, and have the added advantage of defining the hemodynamic effects of valvular or device infection. Native and prosthetic valve IE, infections relating to cardiac implantable electronic devices, and indwelling catheters are effectively evaluated with echocardiography. However, complementary imaging is occasionally required when there remains diagnostic uncertainty following transesophageal echocardiography. Multidetector computed tomography and nuclear imaging techniques such as positron emission tomography and white blood cell scintigraphy have been shown to reduce the rate of misdiagnosed IE particularly in the setting of prosthetic valve endocarditis, paravalvular extension of infection, and cardiac implantable electronic devices. In this review, we describe a modern approach to cardiac imaging in native and prosthetic valve endocarditis, as well as cardiac implantable electronic devices including pacing devices and left ventricular assist devices. Current guidelines addressing the role of multimodality imaging in IE are discussed. The utility of imaging in the assessment of local and distant endocarditis complications such as pericardial sequelae, myocarditis, and embolic events is also addressed.

Objectives: This study sought to assess the impact of systolic variation of mitral regurgitation (MR) has on discordance between echocardiography and magnetic resonance imaging (MRI)., Background: Studies have shown discordance between echocardiography and MRI when assessing the severity of MR. Contributing factors to this discordance may include the systolic variation of MR and the use of the color Doppler jet at a single point in time as the basis of many echocardiographic methods., Methods: This analysis included 117 patients (62 ± 14 years of age; 58% male) with MR who underwent echocardiographic and MRI evaluation. Discordance was defined as the difference between the grades of MR (mild, moderate, or severe) by MRI and echocardiography. For each patient, 2 echocardiographic methods, the continuous wave time index and the color Doppler time index, and 1 MRI method, the systolic variation score (SVS), were measured to quantify systolic variation of MR., Results: There was absolute agreement between echocardiography and MRI in 47 (40%) patients, a 1-grade difference in 54 (46%) patients, and a 2-grade difference in 16 (14%) patients. Only the SVS significantly differed between patients with and without discordance (0.60 ± 0.23 vs. 0.47 ± 0.21; p = 0.003). On receiver-operating characteristic analysis SVS had moderate predictive power of discordance (area under the curve: 0.67; p = 0.003), with an SVS of 53 having a sensitivity of 61% and a specificity of 65% to predict discordance., Conclusions: Discordance between MRI and echocardiographic assessment of MR severity is associated with systolic variation of MR as quantified by MRI using the SVS. Continuous wave Doppler and the presence of color Doppler were not correlated with discordance. This study highlights an advantage of MRI. Namely, it does not rely on a single point in time to determine MR severity. Because systolic variation had only moderate sensitivity and specificity for predicting discordance, other factors are also responsible for the discordance between the 2 techniques., (Copyright © 2019 American College of Cardiology Foundation.
