Background There is a paucity of data about the prevalence and natural history of mitral annular calcification (MAC). Purposes In a large cohort of patients undergoing clinically-indicated echocardiography, we aimed to evaluate the prevalence and the natural history of MAC, and the frequency of associated mitral valve dysfunction (MVD). Methods Retrospective review of all patients who underwent echocardiographic evaluation at our institution between January 1st and December 31st 2015. The patients were stratified into 3 groups: MAC with MVD, MAC without MVD, no MAC. MVD was defined as moderate or greater mitral regurgitation (MR) or stenosis (MS). The 3 groups were compared for baseline clinical and echocardiographic characteristics and all-cause mortality during follow-up. Results Of 24,415 evaluated patients, 5478 (22%) had MAC. Patients with MAC were older (75±10 vs. 60±16 years, p Conclusion In a large cohort of patients undergoing echocardiographic evaluation, the prevalence of MAC was 22%. MV dysfunction was more than twice as prevalent in patients with MAC as without. Patients with MAC had higher all-cause mortality than patients without MAC. Among patients with MAC and mitral valvular dysfunction, adjusted mortality was two-fold higher compared to those without MAC. Funding Acknowledgement Type of funding source: None

Background Prevalence of calcific mitral stenosis (MS) increases with age. Mitral valve interventions for calcific MS are often delayed until symptoms are severely limiting because the natural history of calcific MS and its relation to cardiac symptoms or comorbidities have not been well assessed. Objectives We assessed the prevalence of symptoms, comorbidities and determinants of all-cause mortality in patients with severe calcific MS. Methods We retrospectively investigated adults with echocardiographic isolated severe MS, defined as mitral valve area (MVA by the continuity equation) ≤1.5 cm2, from July 2003 to December 2017. Among them, calcific MS was identified as obstruction of left ventricular inflow due to degenerative calcification of the mitral annulus using echocardiography and, whenever available, operative findings including histopathological examination. Inactivity was defined as requirement for assistance with activities of daily living. Follow up was obtained by review of medical records. Results Of 491 patients with isolated severe MS, calcific MS was present in 200 (41%; age 78±11 years, 18% men, 32% with atrial fibrillation). Charlson Comorbidity Index (CCI) was 5.1±1.7 and 14 (7%) were inactive. MVA and transmitral gradient (TMG) were 1.26±0.19 cm2 and 8.1±3.8 mmHg, respectively. Symptoms were present at baseline in 120 (60%) including dyspnea in 97, chest discomfort in 12, syncope in 3, lower extremity edema in 3, thrombosis in 3 and fatigue in 2. Of them, mitral valve interventions including surgical or transcatheter mitral valve replacement and mitral valve bypass were performed in 27 (23%): within 1 year after index TTE in 23 (19%) and at 2, 4, 5 and 6 years in 1 each. Of 80 patients without symptoms at index TTE, 20 (25%) developed symptoms at mean 2.9±3.2 years and interventions were performed in 5 (6%). Of 168 who did not receive interventions, 60 (36%) did not develop symptoms during follow up, 58 (35%) were considered to have moderate MS, 46 (27%) were not offered surgery because of high risk due to advanced age, multiple comorbidities or heavy calcification, and 2 (1%) declined interventions. During follow-up of 2.8±3.0 years, Kaplan-Meier survival at 1 and 3 years without intervention were 72% and 52%, respectively (Fig. A). Inactivity, CCI >5, left ventricular ejection fraction (LVEF) Conclusion Patients with isolated severe calcific MS had a high burden of comorbidities and had high mortality without intervention. Symptoms were common (60%), but were not associated with mortality. TMG ≥8 mmHg, RVSP ≥50 mmHg, LVEF5 and inactivity were independently associated with mortality.

The aim of this study was to evaluate 1-year outcomes of valve-in-mitral annular calcification (ViMAC) in the MITRAL (Mitral Implantation of Transcatheter Valves) trial.The MITRAL trial is the first prospective study evaluating the feasibility of ViMAC using balloon-expandable aortic transcatheter heart valves.A multicenter prospective study was conducted, enrolling high-risk surgical patients with severe mitral annular calcification and symptomatic severe mitral valve dysfunction at 13 U.S. sites.Between February 2015 and December 2017, 31 patients were enrolled (median age 74.5 years [interquartile range (IQR): 71.3 to 81.0 years], 71% women, median Society of Thoracic Surgeons score 6.3% [IQR: 5.0% to 8.8%], 87.1% in New York Heart Association functional class III or IV). Access was transatrial (48.4%), transseptal (48.4%), or transapical (3.2%). Technical success was 74.2%. Left ventricular outflow tract obstruction (LVOTO) with hemodynamic compromise occurred in 3 patients (transatrial, n = 1; transseptal, n = 1; transapical, n = 1). After LVOTO occurred in the first 2 patients, pre-emptive alcohol septal ablation was implemented to decrease risk in high-risk patients. No intraprocedural deaths or conversions to open heart surgery occurred during the index procedures. All-cause mortality at 30 days was 16.7% (transatrial, 21.4%; transseptal, 6.7%; transapical, 100% [n = 1]; p = 0.33) and at 1 year was 34.5% (transatrial, 38.5%; transseptal, 26.7%; p = 0.69). At 1-year follow-up, 83.3% of patients were in New York Heart Association functional class I or II, the median mean mitral valve gradient was 6.1 mm Hg (IQR: 5.6 to 7.1 mm Hg), and all patients had ≤1+ mitral regurgitation.At 1 year, ViMAC was associated with symptom improvement and stable transcatheter heart valve performance. Pre-emptive alcohol septal ablation may prevent transcatheter mitral valve replacement-induced LVOTO in patients at risk. Thirty-day mortality of patients treated via transseptal access was lower than predicted by the Society of Thoracic Surgeons score. Further studies are needed to evaluate safety and efficacy of ViMAC.

Objectives We aimed to investigate the invasive hemodynamic changes with transcatheter mitral valve replacement (TMVR) in patients with severe mitral stenosis due to severe mitral annular calcification. Background The hemodynamic response to TMVR in patients with mitral stenosis related to degenerative mitral annular calcification has not been fully elucidated. Methods We conducted retrospective review of patients who underwent successful transseptal TMVR with balloon-expandable valves for symptomatic severe mitral stenosis due to mitral annular calcification at our institution between January 2014 and February 2020. Invasive hemodynamic measurements were obtained both before valve implantation (predeployment) and after (postdeployment). Results Eighteen patients (age 72 ± 10 years, 44% female) were included for the analysis. There was a significant reduction in mean left atrial pressure (23.7 ± 5.6 mmHg versus 20.6 ± 4.8 mmHg; p = .01), left atrial v-wave (mean 39.3 ± 10.2 mmHg versus 32.9 ± 9.9 mmHg; p = .01), and an increase in systemic mean blood pressure (72.6 mmHg ±11.2 versus 79.5 ± 9.9 mmHg; p = .02) postdeployment compared to predeployment. Patients who had symptom improvement at 30-day follow-up tended to have greater reduction in mean left atrial pressure (4.4 ± 4.4 mmHg versus 0.5 ± 5.2 mmHg; p = .16) and v-wave (8.6 ± 9.0 mmHg versus 0.7 ± 8.4 mmHg; p = .10) compared to those who did not experience improvement of symptoms. Conclusions Transseptal TMVR for severe mitral stenosis due to mitral annular calcification is associated with reductions in mean left atrial pressure and left atrial v-wave, and an increase in systemic arterial pressure.

OBJECTIVES The aim of this study was to assess the 30 day incidence of paravalvular leak (PVL) and need for aortic valve reintervention of a fourth generation balloon expandable transcatheter valve with enhanced skirt (4G-BEV) (SAPIEN 3 Ultra) compared with a third generation balloon expandable transcatheter valve (3G-BEV) (SAPIEN 3). BACKGROUND The incidence of PVL has steadily declined with iterative improvements in transcatheter aortic valve replacement (TAVR) technology and implantation strategies. METHODS Patients who underwent TAVR at Mayo Clinic from 7/2018 to 7/2019 were included in a prospective institutional registry. 4G-BEV has been utilized since 2/2019, and, after this date, 3G-BEV and 4G-BEV were simultaneously used. 4G-BEV had three sizes (20, 23, and 26 mm) while 3G-BEV included four sizes (20, 23, 26, and 29 mm). Both cohorts were evaluated at 30 days post-TAVR with a transthoracic echocardiogram to assess for PVL. RESULTS A total of 260 consecutive patients were included. Of these, 101 patients received a 4G-BEV and 159 patients received a 3G-BEV. There were more females (p = .0005) and a lower aortic valve calcium score (p = .02) in the 4G-BEV cohort at baseline. Age, STS risk score, NYHA Class, and aortic valve mean gradient did not differ between groups. 4G-BEV was associated with a lower incidence of mild PVL (10.8 vs. 36.5%; p

Importance Bioprosthetic mitral valves are implanted with increasing frequency but inevitably degenerate, leading to heart failure. Reoperation is associated with high morbidity and mortality. Transcatheter mitral valve-in-valve (MViV) using balloon-expandable transcatheter valves has emerged as an alternative for high-surgical risk patients. Objective To assess contemporary outcomes of SAPIEN 3 (Edwards Lifesciences) MViV replacement. Design, setting, and participants In this registry-based prospective cohort study of SAPIEN 3 MViV, patients entered in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry from June 2015 to July 2019 were analyzed. US Centers for Medicare and Medicaid linkage ensured comprehensive collection of death and stroke data. Exposures Mitral valve-in-valve for degenerated bioprosthetic mitral valves. Main outcomes and measures The primary efficacy end point was 1-year mortality. The primary safety end point was procedural technical success as defined by the Mitral Valve Academic Research Consortium criteria. Secondary end points included 30-day mortality, New York Heart Association-defined heart failure, and mitral valve performance. Results A total of 1529 patients (mean [SD] age, 73.3 [11.84] years; 904 women [59.1%]) underwent transseptal or transapical MViV implant at 295 hospitals between June 2015 and July 2019. The mean (SD) Society of Thoracic Surgeons predicted risk of mortality was 11.1% (8.7%). Procedural technical success was achieved for 1480 of 1529 patients (96.8%). All-cause mortality was 5.4% at 30 days and 16.7% at 1 year. Transseptal access was associated with lower 1-year all-cause mortality than transapical access (15.8% vs 21.7%; P = .03). Transcatheter MViV led to early, sustained, and clinically meaningful improvements in heart failure (class III/IV New York Heart Association heart failure of 87.1% at baseline vs 9.7% at 1 year). The mean (SD) mitral valve gradient at 1 year was 7 (2.89) mm Hg. Conclusions and relevance Transcatheter MViV using the SAPIEN 3 transcatheter heart valve is associated with high technical success, low 30-day and 1-year mortality, significant improvement of heart failure symptoms, and sustained valve performance. Transseptal MViV should be considered an option for most patients with failed surgical bioprosthetic valves and favorable anatomy.

Background Iatrogenic mitral stenosis is a known limitation of transcatheter edge-to-edge mitral valve repair (TMVr), but determinants of increased postprocedural mean diastolic gradient (MG) are not well defined. The aim of this study was to determine correlates of increased post-TMVr MG or aborted clip implantation due to increased MG. Methods Procedural three-dimensional transesophageal echocardiographic (TEE) data sets of 112 patients who underwent TMVr were retrospectively analyzed. Three-dimensional TEE mitral valve area (MVA) planimetry and mitral annular calcification (MAC) were quantified using multiplanar reconstruction. When MAC extension into the mitral leaflets was present, MAC with leaflet calcification (MAC-LC) length was recorded as the maximum distance from the mitral annulus to the most distal leaflet calcification. Increased MG after TMVr, measured on intraprocedural TEE imaging, was defined as ≥5 mm Hg or aborted clip implantation due to increased MG. Results Baseline MVA was 5.9 ± 1.7 cm2, baseline MG was 2.1 ± 1.2 mm Hg, and MAC-LC length was 4.0 ± 4.5 mm. Thirty-two patients (29%) had increased post-TMVr MG. Risk for increased post-TMVr MG was 86%, 28%, and 14% in patients with baseline MVA 6.0 cm2, respectively (P 6.0 cm2, the risk for increased post-TMVr MG was similar in the presence or absence of baseline MG ≥ 4 mm Hg or MAC-LC ≥ 6 mm (P > .05 for both). Conclusions Patients with baseline three-dimensional TEE MVA

Background The use of Impella® to provide hemodynamic support during unprotected left main coronary artery (LMCA) percutaneous coronary intervention (PCI) has been shown to be feasible, but severe AS is a relative contraindication for its use. Balloon aortic valvuloplasty (BAV) may facilitate the use of Impella® in these patients. Objective To assess the feasibility of BAV followed by Impella®-assisted LMCA PCI in patients with severe AS as bridge to TAVR. Methods Patients with symptomatic severe AS with LMCA stenosis ≥70% requiring PCI prior to TAVR were included. Outcomes were retrospectively collected. Results Seven patients underwent BAV followed by Impella®-assisted LMCA PCI. Five patients were male; mean age 86 (75–91; SD ± 5.5). Mean STS score was 6.5% (4.3–13.8; SD ± 3.4). Impella® 2.5 L was used in all cases. The procedure was successful in all patients without peri-procedure complications. At 30-day post-BAV/PCI follow up, all patients had experienced improvement in NYHA class (N = 2 NYHA IV to III, N = 5 NYHA III to II). At such interval, mean EF was 54% (30–77; SD ± 17.7). The post BAV change in AVA [0.8 cm2 (0.4–1.5; SD ± 0.3; P = 0.07)], and AV mean gradient [30.8 mmHg (21–45; SD ± 8.9; P = 0.95)] after the procedure were not statistically significant. All patients underwent TAVR after a median PCI-to-TAVR interval of 62 days (33–339; SD ± 96.7). Conclusions BAV followed by Impella®-assisted LMCA PCI appears to be a feasible strategy for intermediate and high surgical risk patients with severe AS undergoing LMCA PCI as bridge to TAVR.

Background: Transcatheter mitral valve replacement using aortic transcatheter heart valves has recently become an alternative for patients with degenerated mitral bioprostheses, failed surgical repairs with annuloplasty rings or severe mitral annular calcification who are poor surgical candidates. Outcomes of these procedures are collected in the Society of Thoracic Surgeons/American College of Cardiology/Transcatheter Valve Therapy Registry. A comprehensive analysis of mitral valve-in-valve (MViV), mitral valve-in-ring (MViR), and valve-in-mitral annular calcification (ViMAC) outcomes has not been performed. We sought to evaluate short-term outcomes of early experience with MViV, MViR, and ViMAC in the United States. Methods: Retrospective analysis of data from the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. Results: Nine hundred three high-risk patients (median Society of Thoracic Surgeons score 10%) underwent MViV (n=680), MViR (n=123), or ViMAC (n=100) between March 2013 and June 2017 at 172 hospitals. Median age was 75 years, 59.2% female. Technical and procedural success were higher in MViV. Left ventricular outflow tract obstruction occurred more frequently with ViMAC (ViMAC=10%, MViR=4.9%, MViV=0.7%; P P =0.004) and 30-day mortality (MViV=8.1%, MViR=11.5%, ViMAC=21.8%; P =0.003) were higher in ViMAC. At 30-day follow-up, median mean mitral valve gradient was 7 mm Hg, most patients (96.7%) had mitral regurgitation grade ≤1 (+) and were in New York Heart Association class I to II (81.7%). Conclusions: MViV using aortic balloon-expandable transcatheter heart valves is associated with a low complication rate, a 30-day mortality lower than predicted by the Society of Thoracic Surgeons score, and superior short-term outcomes than MViR and ViMAC. At 30 days, patients in all groups experienced improvement of symptoms, and valve performance remained stable. Registration: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT02245763.

Alcohol septal ablation (ASA) and septal myectomy (SM) are therapeutic interventions for patients with hypertrophic cardiomyopathy (HC) who remain symptomatic despite medical treatment. Outcomes for both interventions in age groups ≤65 versus65 years are scarce. We queried the National Readmission Database for adult patients undergoing either SM or ASA between 2010 and 2015 for HC. Patients were divided into 2 age-groups (≤65-years and65-years). We aimed to compare the in-hospital mortality, complication rates, and resource utilization for each procedure between the 2 age-groups. We identified 4,358 patients with HC who underwent intervention, of which 2,113 were treated with SM and 2,245 with ASA. In-hospital mortality was 6-times higher in patients ≤65 years old who underwent SM compared with ASA (1.5% vs 0.3% odds ratio 6.2; p = 0.04); and 4-times higher in patients65 years treated with SM compared with ASA (6.7% vs 1.7% odds ratio 4.29; p = 0.04). Blood transfusion rates and stroke were higher in patients undergoing SM, regardless of their age-group. Length of hospital stay was lower in the ASA group (3 days vs 6 days for both age groups, p0.001) as well as median hospital costs (≤65 years old: $15,474 vs $31.531; and65 years old: $16,672 vs $36,042, p0.001). In conclusion, patients with HC treated with ASA had significantly lower in-hospital mortality, complications rates, length of hospital stay, and hospital costs compared with patients undergoing SM at any age.

Oxford Houses (OH) are democratically run, self-funded, substance-use recovery homes that operate across the United States and internationally. Previous research shows the OHs are present in diverse neighborhoods. The current study examined the neighborhoods of 42 OHs located in Oregon, Texas, and North Carolina to better quantify and understand house and neighborhood characteristics that are related to relapse rates. Independent variables were participants' length of stay in OH, wages earned from employment, and income/education neighborhood characteristics. Neighborhood characteristics were related to relapse rates, with higher relapse rates occurring in neighborhoods with lower income and education levels. This finding supports the OH organization's premise that while OHs may work across community settings, they perform better in neighborhoods with higher average income and education levels.

Background Transcatheter edge-to-edge mitral valve repair (TMVR; MitraClip, Abbott Vascular) is clinically approved for treatment of severe, symptomatic mitral regurgitation (MR) in high or prohibitive surgical risk patients. Iatrogenic mitral stenosis is a known complication of TMVR, but determinants of increased post-procedure mean diastolic gradient are not well defined. Purpose We aimed to investigate the determinants of increased mitral mean diastolic gradient after TMVR. Methods We retrospectively reviewed 59 patients. 2D and 3D TEE data sets acquired before and immediately after procedure were analyzed. 4D Cardio-View and 4D MV-Assessment (TomTec, Germany) were used for the analysis of the 3D volume data set. Quantitative mitral valve analysis was done at the end of systole. Increased mitral mean diastolic gradient after TMVR was correlated with pre-procedure 2D and 3D echocardiographic data. Results 34 patients had primary MR, 25 patients had mixed/secondary MR. Baseline mean mitral diastolic gradient was 2.0 ± 0.9mmHg and increased to 3.9 ± 1.8mmHg post-TMVR and the mean 3D planimetric mitral valve area decreased from 5.3 ± 1.5cm2 to 2.6 ± 1.0cm2. Implantation of multiple clips was performed less frequently in patients with smaller baseline mitral valve area; 8% vs 47% in the lowest quartile vs all others (p = 0.006). 12(20%) of patients had a mean diastolic gradient >5mmHg post-TMVR and 15(25%) of patients had a post-TMVR mitral valve area 5mmHg (p = 0.08). Patient characteristics according to post-TMVR mean diastolic gradient are shown in the Table. Post-TMVR mean diastolic gradient >5mmHg was more common in patients with increased pre-procedure mean diastolic gradient(p = 0.006), post-TMVR mitral valve area 5mmHg(p = 0.04). Conclusions Elevated post-TMVR mean diastolic gradient is multifactorial and related to mitral stenosis, but residual mitral regurgitation also appears to be an important contributor to increased gradients in some patients. Larger cohorts are likely needed to assess the concurrent impact of mitral annular calcification, leaflet calcification, and other variables on post-TMVR mean gradient.

Social network data were collected among residents of an Oxford House (OH) recovery home, which was located on Suquamish Tribal territory. Data were collected on the social connections of eight male residents (including four Native Americans and four non-Native Americans) using a social network instrument. A number of social network relationship types were examined, including friendship, trust, and mentorship. Social network data assessed included diameter, reciprocity, the average path length, cohesion, density, transitivity, and centrality. Findings indicated that the OH provided residents a well-integrated network with multiple sources of friendship, trust, and mentors. This is of importance as recovery from substance abuse is facilitated when recovering individuals are provided stable and well-functioning networks that foster social support, access to resources, and mentorship.

To assess the outcomes of transatrial implantation of a transcatheter heart valve (THV) for the treatment of mitral valve disease with severe mitral annular calcification (MAC).Implantation of a balloon-expandable THV was performed on cardiopulmonary bypass via left atrial exposure in patients considered at risk for left ventricular outflow tract obstruction. The anterior mitral valve leaflet was systematically resected and pledgeted sutures were placed to enhance stability and reduce paravalvular leak.Twenty-six consecutive symptomatic patients with severe MAC (mean age, 78 ± 7 years; 92% female; mean Society of Thoracic Surgeons score, 9.4 ± 4.8) were included at 6 different centers. Two patients (8%) received an Edwards Sapien XT (Edwards Lifesciences, Irvine, Calif), and 24 (92%) an Edwards Sapien 3 bioprosthesis (Edwards Lifesciences). Concomitant aortic valve replacement was performed in 11 patients. Technical success according to the criteria of the Mitral Valve Academic Research Consortium was achieved in all patients. The mean transmitral gradient decreased from 10 ± 5 to 4 ± 2 mm Hg (P .001) with trace or mild regurgitation in all patients. An elevated mean transaortic gradient (30 mm Hg) was observed in 1 patient (4%). Five patients died during hospital stay (19%) and 2 additional between discharge and 30 days (30-day mortality: 27%). Sustained functional improvement was observed in the remaining patients.Transatrial implantation of a THV for the treatment of MAC is associated with high technical success despite unfavorable anatomy. In this early experience of very high surgical risk patients, 30-day all-cause mortality was high. Patients at particular risk appear to be those with chronic kidney disease requiring multiple valve surgery.

Background The risk of surgical mitral valve replacement in patients with severe mitral annular calcification (MAC) is high. Several patients worldwide with severe MAC have been treated successfully with transcatheter mitral valve replacement (TMVR) using balloon-expandable aortic transcatheter valves. The TMVR in MAC Global Registry is a multicenter registry that collects data on outcomes of these procedures. Objectives The goal of this study was to evaluate 1-year outcomes in this registry. Methods This study was a multicenter retrospective review of clinical outcomes. Results A total of 116 extreme surgical risk patients with severe MAC underwent TMVR; 106 had a procedure date >1 year before data-lock and were included in the analysis. Their mean age was 73 ± 12 years, and 68% were female. The mean Society of Thoracic Surgeons score was 15.3 ± 11.6%, and 90% were in New York Heart Association functional class III or IV. Thirty-day and 1-year all-cause mortality was 25% and 53.7%, respectively. Most patients who survived 30 days were alive at 1 year (49 of 77 [63.6%]), and the majority (71.8%) were in New York Heart Association functional class I or II. Echocardiography data at 1 year were available in 34 patients. Mean left ventricular ejection fraction was 58.6 ± 11.2%, mean mitral valve area was 1.9 ± 0.5 cm2, mean mitral gradient was 5.8 ± 2.2 mm Hg, and 75% had zero or trace mitral regurgitation. Conclusions TMVR with balloon-expandable aortic valves in extreme surgical risk patients with severe MAC is feasible but associated with high 30-day and 1-year mortality. Most patients who survive the 30-day post-procedural period are alive at 1 year and have sustained improvement of symptoms and transcatheter valve performance. The role of TMVR in patients with MAC requires further evaluation in clinical trials.

Acute obstruction of the neo-LVOT is a major and potentially fatal complication of transcatheter mitral valve implantation. Patients at high risk of this complication can be identified preoperatively with cardiac CT. We describe a case of a patient identified as high risk for developing neo-LVOT obstruction, who was preemptively treated with alcohol septal ablation prior to successful valve implantation.

OBJECTIVE Demonstrate proof-of-concept validation of a computed tomography (CT) computer-aided design prediction modeling tool to identify patients at risk for left ventricular outflow tract (LVOT) obstruction in transcatheter mitral valve replacement (TMVR). BACKGROUND LVOT obstruction is a significant and even fatal consequence of TMVR. METHODS From August 2013 to August 2017, 38 patients in 5 centers underwent TMVR with compassionate use of balloon-expandable valves for severe mitral valve dysfunction because of degenerative surgical mitral ring, bioprosthesis, or severe native mitral stenosis from to severe mitral annular calcification. All patients had preprocedural CT scans performed for anatomic screening, intraprocedural TEE and invasive hemodynamics performed. Preprocedural prediction modeling was performed utilizing computer-aided design (CAD) of the neo-LVOT post-TMVR. Post-TMVR CT scans were obtained and compared to pre-TMVR LVOT modeling datasets for validation. RESULTS All patients underwent successful TMVR without device embolization. Seven of the 38 patients experienced LVOT obstruction, defined as an increase of ≥10 mmHg LVOT peak gradient post-TMVR. Anatomic screening using CT was validated in 20/38 patients as preprocedural predicted neo-LVOT surface area correlated well with post-TMVR measurements (R2 = 0.8169, P

BACKGROUND Degenerated surgical mitral valve repairs or surgical prostheses are currently being treated with transcatheter mitral valve replacement (TMVR). We report the procedural and mid-term assessment of thirteen cases. METHODS From 12/2013 to 12/2015, 13 consecutive patients with degenerated mitral valve repair or valve replacement were treated. Patients were assessed for mitral valve academic valve consortium (MVARC) defined outcomes. RESULTS Immediate procedural MVARC defined technical success was 92%. At 30 days MVARC device and procedure success were 61% and 84%, respectively. Mean follow-up was 150 days [IQR 40-123 days]. There were 2 late major adverse outcomes, a noncardiac related death (628 days) and a stroke (382 days). The mean mitral gradient decreased from 9.5 ± 3.4 to 5.5 ± 2.6 mm Hg (P

We assessed the impact of clerical and life stressors on the religious commitments of employed, married with children Catholic deacons (n = 317 men: M age = 43.87 years old). Independent of social desirability, stressors during the last 6 months predicted separately intracommitment and intercommitment variables. Enthusiasm for church work and time spent on spiritual reflection predicted religious intracommitment (one’s relationship with a higher power, God); study of Scripture predicted religious intercommitment (one’s relationship in community reflecting God’s presence). Results suggest that despite current stressful life demands of marriage and family plus outside employment, Catholic deacons (“clergy dads”) maintained religious beliefs.

Background Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. Objectives This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery. Methods Patients underwent transcatheter, transapical delivery of a self-expanding mitral valve prosthesis and were examined in a prospective registry for short-term and 30-day outcomes. Results Thirty patients (age 75.6 ± 9.2 years; 25 men) with grade 3 or 4 MR underwent TMVR. The MR etiology was secondary (n = 23), primary (n = 3), or mixed pathology (n = 4). The Society of Thoracic Surgeons Predicted Risk of Mortality was 7.3 ± 5.7%. Successful device implantation was achieved in 28 patients (93.3%). There were no acute deaths, strokes, or myocardial infarctions. One patient died 13 days after TMVR from hospital-acquired pneumonia. Prosthetic leaflet thrombosis was detected in 1 patient at follow-up and resolved after increased oral anticoagulation with warfarin. At 30 days, transthoracic echocardiography showed mild (1+) central MR in 1 patient, and no residual MR in the remaining 26 patients with valves in situ. The left ventricular end-diastolic volume index decreased (90.1 ± 28.2 ml/m2 at baseline vs. 72.1 ± 19.3 ml/m2 at follow-up; p = 0.0012), as did the left ventricular end-systolic volume index (48.4 ± 19.7 ml/m2 vs. 43.1 ± 16.2 ml/m2; p = 0.18). Seventy-five percent of the patients reported mild or no symptoms at follow-up (New York Heart Association functional class I or II). Successful device implantation free of cardiovascular mortality, stroke, and device malfunction at 30 days was 86.6%. Conclusions TMVR is an effective and safe therapy for selected patients with symptomatic native MR. Further evaluation of TMVR using prostheses specifically designed for the mitral valve is warranted. This intervention may help address an unmet need in patients at high risk for surgery.

This study aims to establish a computed tomography (CT)-based scoring system for grading mitral annular calcification (MAC) severity and potentially aid in predicting valve embolization during transcatheter mitral valve (MV) replacement using balloon-expandable aortic transcatheter heart valves.Transcatheter MV replacement is emerging as an alternative treatment for patients with severe MAC who are not surgical candidates. Although cardiac CT is the imaging modality of choice in the evaluation of candidates for valve-in-MAC (ViMAC), a standardized grading system to quantify MAC severity has not been established.We performed a multicenter retrospective review of cardiac CT and clinical outcomes of patients undergoing ViMAC. A CT-based MAC score was created using the following features: average calcium thickness (mm), degrees of annulus circumference involved, calcification at one or both fibrous trigones, and calcification of one or both leaflets. Features were assigned points according to severity (total maximum score = 10) and severity grade was assigned based on total points (mild ≤3, moderate 4 to 6, and severe ≥7 points). The association between MAC score and device migration/embolization was evaluated.Of 117 patients in the TMVR in MAC registry, 87 had baseline cardiac CT of adequate quality. Of these, 15 were treated with transatrial access and were not included. The total cohort included 72 (trans-septal = 37, transapical = 35). Mean patient age was 74 ± 12 years, 66.7% were female, and the mean Society of Thoracic Surgery risk score was 15.4 ± 10.5%. The mean MAC score was 7.7 ± 1.4. Embolization/migration rates were lower in higher scores: Patients with a MAC score of 7 had valve embolization/migration rate of 12.5%, MAC score ≥8 had a rate of 8.7%, and a MAC score of ≥9 had zero (p = 0.023). Patients with a MAC score of ≤6 had 60% embolization/migration rate versus 9.7% in patients with a MAC score ≥7 (p 0.001). In multivariable analysis, a MAC score ≤6 was in independent predictor of valve embolization/migration (odds ratio [OR]: 5.86 [95% CI: 1.00 to 34.26]; p = 0.049).This cardiac CT-based score provides a systematic method to grade MAC severity which may assist in predicting valve embolization/migration during trans-septal or transapical ViMAC procedures.

BACKGROUND Transcatheter edge-to-edge repair with MitraClip is only approved for treatment of mitral regurgitation but is increasingly used to treat concomitant tricuspid regurgitation (TR) due to its common coexistence and association with poor outcomes. This study aimed to describe the learning curve associated with the challenge of off-label treatment of concomitant TR. METHODS This is a retrospective review of initial and consecutive patients who underwent combined edge-to-edge repair of mitral and tricuspid valves (TVs) at our institution from August 2017 to October 2019. RESULTS Repair of both valves with MitraClip was performed in 22 patients (median age 81.5 years, 32% female). Mean procedure time was 176 ± 47 min; mean fluoroscopy time was 65 ± 24 min. Procedure duration in the first tertile was significantly longer (223 ± 13 min) than in the third tertile (143 ± 23 min, p = .0003). Median number of total clips placed per case was 3; in 15 patients (68%), the anterior and septal leaflets of the TV were clipped. The average changes in mean right atrial (RA) and left atrial (LA) pressures were -1.7 ± 2.5 mmHg (p = .0080) and -3.2 ± 4.6 mmHg (p = .0045), respectively. The average changes in RA and LA V-wave heights were -3.3 ± 4.0 mmHg (p = .0009) and -8.1 ± 9.9 mmHg (p = .038), respectively. There was a significant trend toward decreasing residual TR over the course of the series (p = .046). At 30 days, survival was 100% and mean NYHA class decreased from 2.8 to 1.8 (p

Transcatheter tricuspid valve in valve (TViV) is increasingly performed on patients with degenerated bioprosthetic valves and elevated surgical risk. Jailing a right ventricular (RV) pacer lead at the time of TViV implantation has been achieved without causing lead dysfunction; however, device-related complications that require lead extraction raise the need for better periprocedural strategies for TViV, in pacer-dependent patients. We describe a case of device pocket infection with incomplete lead extraction, due to a jailed RV lead at the time of TViV.

AIMS: Ensuring recovery home residents’ social integration into a home environment is important for preventing early dropout and facilitating sustained recovery. Social Capital Theory may provide an explanation for how recovery homes may protect residents and improve recovery rates. However, little is known about how social capital in recovery home environments is structured and accessed. Recovery homes may increase social capital by sharing bonds through friendships, lending money, and advice-seeking. METHODS: The current study describes social network cross sectional data obtained from a study of 42 Oxford House recovery homes, in three locations in the US (North Carolina, Texas and Oregon). The residents rated each member of their house on the dimensions of friendship, money loaning, and advice seeking to assess how each resident views one another on these dimensions. The research used baseline data from a larger longitudinal study, and although some data were presented for the full sample (APL, isolates, mean reciprocity and density), the results primarily focused on case studies for three of the participating Oxford Houses—with examples of low, median, and high “connected” houses respectively. Standard measures of network structures were calculated for each home. RESULTS: Although all Oxford Houses follow the same house rules, they were found to vary in network structure. Findings indicated a considerable range of interconnectedness among residents in these houses, with friendship being the most common relationship, willingness to lend money less common, and advice-seeking the least common. CONCLUSIONS: The findings on friendship, willingness to lend, and advice-seeking provide promising leads about what occurs among the social networks within these complex eco-systems, and may provide ways to better understand and facilitate resident social integration into these settings.

Open surgical closure and small-bore suture-based preclosure devices have limitations when used for transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, or percutaneous thoracic endovascular aortic aneurysm repair. The MANTA vascular closure device is a novel collagen-based technology designed to close large bore arteriotomies created by devices with an outer diameter ranging from 12F to 25F. In this study, we determined the safety and effectiveness of the MANTA vascular closure device.A prospective, single arm, multicenter investigation in patients undergoing transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, or thoracic endovascular aortic aneurysm repair at 20 sites in North America. The primary outcome was time to hemostasis. The primary safety outcomes were accessed site-related vascular injury or bleeding complications. A total of 341 patients, 78 roll-in, and 263 in the primary analysis cohort, were entered in the study between November 2016 and September 2017. For the primary analysis cohort, transcatheter aortic valve replacement was performed in 210 (79.8%), and percutaneous endovascular abdominal aortic aneurysm repair or thoracic endovascular aortic aneurysm repair was performed in 53 (20.2%). The 14F MANTA was used in 42 cases (16%), and the 18F was used in 221 cases(84%). The mean effective sheath outer diameter was 22F (7.3 mm). The mean time to hemostasis was 65±157 seconds with a median time to hemostasis of 24 seconds. Technical success was achieved in 257 (97.7%) patients, and a single device was deployed in 262 (99.6%) of cases. Valve Academic Research Consortium-2 major vascular complications occurred in 11 (4.2%) cases: 4 received a covered stent (1.5%), 3 had access site bleeding (1.1%), 2 underwent surgical repair (0.8%), and 2 underwent balloon inflation (0.8%).In a selected population, this study demonstrated that the MANTA percutaneous vascular closure device can safely and effectively close large bore arteriotomies created by current generation transcatheter aortic valve replacement, percutaneous endovascular abdominal aortic aneurysm repair, and thoracic endovascular aortic aneurysm repair devices.URL: https://www.clinicaltrials.gov .

OBJECTIVES A large comprehensive analysis of transcatheter aortic valve replacement (TAVR) was performed for failed stentless bioprostheses.BACKGROUND Valve-in-valve (ViV) transcatheter aortic replacement (TAVR) is an alternative to redo surgery for patients with a failing aortic bioprosthesis.METHODS Unadjusted outcome data were collected from the VIVID (Valve-in-Valve International Data) registry between 2007 and 2016 from a total of 1,598 aortic ViV procedures (291 stentless, 1,307 stented bioprostheses).RESULTS Bioprosthetic failure was secondary to aortic regurgitation in 56% of stentless and 20% stented devices (p < 0.001). ViV-TAVR access was transfemoral in 71.1% stentless and 74.2% stented ViV-TAVR. Self-expanding devices were more frequently used in stentless ViV-TAVR (56.0% vs. 39.9%; p = 0.05), but there was no difference between balloon-expanding and self-expanding TAVR devices for stented ViV-TAVR (48.6% vs. 45.1%). The degree of oversizing for all mechanisms of bioprosthesis failure was 9 +/- 10% for stentless ViV-TAVR vs. 6 +/- 9% for stented ViV-TAVR (and 8 +/- 10% for stentless ViV-TAVR vs. 3 +/- 9% for stented ViV-TAVR in patients with predominant aortic regurgitation; both p < 0.001). Initial device malposition (10.3% vs. 6.2%; p = 0.014), second transcatheter device (7.9% vs. 3.4%), coronary obstruction (6.0% vs. 1.5%), and paravalvular leak occurred more frequently in stentless ViV-TAVR (all p < 0.001). Hospital stay duration (median 7 days) was no different, and 30-day (6.6% vs. 4.4%; p = 0.12) and 1-year mortality year (15.8% vs. 12.6%; p = 0.15) were numerically higher, but not statistically different, after stentless ViV-TAVR.CONCLUSIONS Stentless ViV-TAVR is associated with greater periprocedural complications (initial device malposition, second transcatheter device, coronary obstruction, paravalvular leak), but no difference in 30-day and 1-year outcome.

Highlights •Computed tomography is an essential imaging modality for patient selection and procedural planning of catheter-based mitral valve interventions on a prosthetic valve or calcified native annulus. •Echocardiography and limited fluoroscopy are principal imaging tools for intraprocedural guidance. Echocardiography is well suited for acute postprocedure functional evaluation. •Accurate prediction of left ventricular outflow tract patency is a specific imaging challenge for these interventions. •Functional evaluation of residual mitral regurgitation and paravalvular regurgitation post procedure are important tasks for the echocardiographer.

In 2016, two Oxford House (OH) recovery homes were established for the Suquamish Tribal reservation. A group of researchers interviewed house members and key individuals responsible for the creation of these two unique OHs. Because American Indians are an at-risk population for substance use disorders, our study explored whether an OH-type recovery home model could be successfully adapted to this population, given the specific nature of tribal cultures. Findings indicated that the residents, composed of both American Indians and non-American Indians, found these OHs to be supportive of recovery in general and with the values of American Indians. The tribal community's positive attitudes toward these recovery homes may have been due to similarities between the Suquamish Tribal Government and OH's democratic structures, with all individuals having a voice in the decision making process. The overall findings suggest that these types of culturally modified recovery settings on American Indian tribal lands could be an important resource for individuals dealing with substance use disorders.

Objective To describe the hemodynamic and early clinical outcomes of percutaneous alcohol septal ablation in patients with concomitant dynamic left ventricular outflow tract (LVOT) obstruction and aortic valvular stenosis (AS). Background Alcohol septal ablation is an established method to relieve dynamic LVOT obstruction in patients with hypertrophic cardiomyopathy (HCM). However, the feasibility, safety, and efficacy of alcohol septal ablation in patients with serial obstructions from HCM and AS remain unclear. Methods In this case series, we describe the early outcomes of alcohol septal ablation in six patients with significant dynamic LVOT obstruction and AS. All patients had evidence of severe dynamic LVOT obstruction (resting or provoked gradient ≥50 mmHg), mild to severe AS, and NYHA class III symptoms or greater. Results Four (66.7%) patients had septal ablation performed in the setting of concomitant native valvular AS and two (33.3%) patients had TAVR performed prior to septal ablation. Successful alcohol septal ablation was performed in all patients and was associated with an immediate reduction of the dynamic LVOT gradient with a residual fixed obstruction related to AS. Four (66.7%) patients had follow-up at 1 month and of these, three (75%) had NYHA Class I-II symptoms and one (25%) Class III. Conclusions Alcohol septal ablation is a feasible method of relieving dynamic LVOT obstruction in patients with concomitant HCM and AS. Further study is required to determine the optimal treatment approach in these patients.

OBJECTIVES The authors sought to collect data on contemporary practice and outcome of transcatheter aortic valve replacement (TAVR) in oncology patients with severe aortic stenosis (AS). BACKGROUND Oncology patients with severe AS are often denied valve replacement. TAVR may be an emerging treatment option. METHODS A worldwide registry was designed to collect data on patients who undergo TAVR while having active malignancy. Data from 222 cancer patients from 18 TAVR centers were compared versus 2,522 "no-cancer" patients from 5 participating centers. Propensity-score matching was performed to further adjust for bias. RESULTS Cancer patients' age was 78.8 +/- 7.5 years, STS score 4.9 +/- 3.4%, 62% men. Most frequent cancers were gastrointestinal (22%), prostate (16%), breast (15%), hematologic (15%), and lung (11%). At the time of TAVR, 40% had stage 4 cancer. Periprocedural complications were comparable between the groups. Although 30-day mortality was similar, 1-year mortality was higher in cancer patients (15% vs. 9%; p < 0.001); one-half of the deaths were due to neoplasm. Among patients who survived 1 year after the TAVR, one-third were in remission/cured from cancer. Progressive malignancy (stage III to IV) was a strong mortality predictor (hazard ratio: 2.37; 95% confidence interval: 1.74 to 3.23; p < 0.001), whereas stage I to II cancer was not associated with higher mortality compared with no-cancer patients. CONCLUSIONS TAVR in cancer patients is associated with similar short-term but worse long-term prognosis compared with patients without cancer. Amongthis cohort, mortality is largely driven by cancer, and progressive malignancy is a strong mortality predictor. Importantly, 85% of the patients were alive at 1 year, one-third were in remission/cured from cancer.

Background There is a need to better understand the extent to which social capital (reflected in social networks tapping friendship, financial support, advice/informational support) can aid recovery for those residents living in abstinence-based recovery homes. Methods Social network characteristics of 42 recovery homes (Oxford Houses) were examined, including friendship, willingness to loan money, and advice-seeking to assess the extent to which house network patterns were related to house-level resident measures of proximal recovery outcomes of well-being (e.g. social support, self-esteem, stress) and financial health (e.g. earned wages). Results We found that the density of the willingness to loan money network within a house was positively associated with house-level earned wages, social support, and self-esteem, and negatively associated with stress. Conversely, the density of house advice-seeking relationships was positively related to house-level stress. Conclusions Houses in which residents are willing to share resources with other members who may be in need showed higher rates of well-being at the house-level. Advice-seeking in itself may signal stress, as stress may motivate residents to seek advice from more peers. The implications of these findings are discussed.

OBJECTIVES The aim of this study was to determine the safety of eliminating the pre-discharge transthoracic echocardiogram (TTE) on 30-day outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND TTE is utilized before, during, and after TAVR. Post-procedural, pre-discharge TTE assists in assessment of prosthesis function and detection of clinically significant paravalvular leak (PVL) after TAVR. METHODS Patients who underwent TAVR at Mayo Clinic from July 2018 to July 2019 were included in a prospective institutional registry. Patients undergoing TAVR prior to February 2019 received a pre-discharge TTE, while those undergoing TAVR after February 2019 did not. Both cohorts were evaluated with TTE at 30 days post-TAVR. RESULTS A total of 330 consecutive patients were included. Of these, 160 patients (age 81.1 ± 7.6) had routine pre-discharge TTE, while 170 patients (age 78.9 ± 7.5) were dismissed without routine pre-discharge TTE. Mortality at 30 days was similar between the two groups (0% and 1.2%, respectively). One episode of PVL requiring intervention (0.6%) occurred in the pre-discharge TTE group and none in the group without pre-discharge TTE at 30-day follow-up. There was a similar incidence of total composite primary and secondary adverse events between the cohort receiving a pre-discharge TTE and those without (28.1% vs. 25.3%, P = 0.56) at 30 days. The most common event was need for permanent pacemaker or ICD implantation in both groups (13.1% vs. 11.8%, P = 0.71). CONCLUSIONS Elimination of the pre-discharge TTE is safe and associated with comparable 30-day outcomes to routine pre-discharge TTE. These findings have implication for TAVR practice cost-efficiency and health care utilization.

Evolution of catheter-based structural interventions has given patients less invasive alternatives to surgery; however, the current generation of transcatheter heart valves (THV) are not specifically designed for mitral position implantation and have intrinsic geometry that may make mitral

Transcatheter implantation of balloon expandable valves in native mitral valves (MV) has been performed in patients with severe MV annular calcification who are not good candidates for standard surgical MV replacement. Significant left ventricular outflow tract (LVOT) obstruction with hemodynamic compromise has been described as one of the potential complications of transcatheter MV replacement. Surgical rescue carries significant risk in this high-risk patient population. We describe a percutaneous technique to acutely decrease transcatheter MV replacement-induced LVOT obstruction. © 2016 Wiley Periodicals, Inc.
