Abstract

Previous reports have suggested that dobutamine stress echocardiography compares favourably with other stress agent-imaging modality combinations for the detection of coronary artery disease. However, in daily clinical practice the value of a test is defined on a probability basis. To study the relative diagnostic contribution of clinical and dobutamine stress test variables, Bayesian analysis was performed in 223 patients with suspected coronary artery disease, who underwent coronary angiography and a high-dose dobutamine stress test in conjunction with electrocardiography, echocardiography and Technetium-99m sestamibi SPECT myocardial perfusion scintigraphy. According to the pre-test (clinical) probabilities, patients were divided into low-, intermediate- and high-risk groups; 155 patients were in the intermediate-visit group. After dobutamine stress echocardiography the number of patients in this intermediate-risk group was reduced to 102 (P<0.0001). This reduction of patients in the intermediate-risk group by echocardiography was better than perfusion scintigraphy (102 vs 126 patients, P<0.05) or classic markers of ischaemia such as angina and/or ST-segment changes (102 vs 150, P<0.0001). Moreover, there was a good correlation between the echocardiographic post-test probabilities and the true distribution of coronary artery disease.

Abstract

Background/objective: Left ventricular (LV) twist has an important role in LV function. The influence of the pattern of LV hypertrophy on LV twist in hypertrophic cardiomyopathy (HCM) patients is unknown. This study sought to assess LV twist in a large group of HCM patients according to the pattern of LV hypertrophy. Methods: The final study population consisted of 43 patients with HCM (mean age 43 (15) years, 31 men) and a typical sigmoidal (n = 16) or reverse septal curvature (n = 27) and 43 age-matched and gender-matched healthy control subjects. LV peak systolic rotation (Rot(max)), LV peak systolic twist (Twist(max)) and untwisting at 5%, 10% and 15% of diastole were determined by speckle tracking echocardiography (STE). Results: Compared to control subjects, HCM patients had increased basal Rot(max) (-5.5 degrees (2.3 degrees ) vs -3.4 degrees (1.7 degrees ), p<0.001) and comparable apical Rot(max) (7.3 degrees (3.1 degrees ) vs 7.0 degrees (2.2 degrees ), p = NS), resulting in increased Twist(max) (12.4 degrees (4.0 degrees ) vs 9.9 degrees (2.7 degrees ), p<0.01). Untwisting at 5%, 10% and 15% of diastole was decreased in HCM patients (all p<0.05). There was a striking difference in apical Rot(max )(9.4 degrees (2.8 degrees ) vs 6.0 degrees (2.6 degrees ), p<0.01) and Twist(max) (15.3 degrees (3.2 degrees ) vs 10.6 degrees (3.3 degrees ), p<0.01) between HCM patients with a sigmoidal and reverse septal curvature. Conclusions: STE may provide novel non-invasive indices to assess LV function in patients with HCM. Apical Rot(max) and Twist(max) in HCM patients are dependent on the pattern of LV hypertrophy.

Abstract

Background: Noncompaction cardiomyopathy (NCCM) is a rare disorder with persistance of the embryonic pattern of myoarchitecture. NCCM is characterized by loosened, spongy myocardium associated with a high incidence of systolic and diastolic left ventricular (LV) dysfunction and heart failure (HF). It is known that LV dysfunction contributes to elevated left atrial (LA) and pulmonary vascular pressures, however atrial function has not been examined in NCCM. The objective of the present study was to assess LA systolic function characterized by LA ejection force (LAEF) in NCCM patients using real-time three-dimensional echocardiography (RT3DE) and to compare to control subjects. Methods: The study comprised 17 patients with an established diagnosis of NCCM and their results were compared to 17 healthy age-matched controls with no evidence of cardiovascular disease. Forty-one percent of NCCM patients were in NYHA functional class II / III HF. Previously proposed echocardiographic diagnostic criteria for NCCM were used. All patients underwent conventional two-dimensional echocardiography and RT3DE. LAEF was measured based on MA annulus diameter (LAEF 3D-MAD) and area (LAEF 3D-MAA) using RT3DE. Results: The presence and severity of mitral regurgitation were more frequent in NCCM patients than in control subjects. LV diameters and mitral annulus were significantly increased in NCCM patients. Compared with control subjects, both LAEF 3D-MAD (3.8 +/- 2.2 vs 2.3 +/- 1.0 kdyne, P < 0.05) and LAEF 3D-MAA (12.7 +/- 7.6 vs 4.9 +/- 2.1 kdyne, P < 0.01) were significantly increased in NCCM patients. Conclusions: LAEF as a characteristic of LA systolic function is increased in NCCM patients compared to normal individuals. These results can suggest compensating left atrial work against the dysfunctional LV in NCCM patients. [ABSTRACT FROM AUTHOR]

Abstract

AIMS: To evaluate the accuracy of real-time three-dimensional echocardiography (RT3DE) using a biplane and multiplane method in determining left ventricular (LV) mass compared to cardiac magnetic resonance imaging (CMR). METHODS AND RESULTS: LV mass was measured in 18 adult patients with congenital aortic stenosis using CMR and echocardiography (M-mode, two-dimensional echocardiography (2DE), and RT3DE). RT3DE data were analysed using a biplane and multiplane method. No geometric assumptions were necessary using the multiplane RT3DE method. With regard to biplane or multiplane RT3DE, no tendency of over- or underestimation of LV mass was observed. Pearson's correlation coefficients for RT3DE versus CMR were 0.84 and 0.90 for the biplane and multiplane method, respectively. In addition, the accuracy of both RT3DE methods were comparable (Fisher's R-to-Z transformation: Z = 0.69, P = NS). Finally, off-line analysis using biplane RT3DE was significantly faster than multiplane RT3DE (3.8 +/- 1.2 vs. 7.8 +/- 1.7 minutes, P < 0.001). CONCLUSIONS: Biplane RT3DE provided an accurate estimate of LV mass in patients with concentric left ventricular hypertrophy, which was not improved by multiplane RT3DE. The accuracy and speed of analysis renders biplane RT3DE an attractive tool in daily clinical practice for assessing the degree of LV hypertrophy. [ABSTRACT FROM AUTHOR]

Abstract

AIMS: Despite its relatively high intra- and inter-observer variability for left ventricular ejection fraction (LV-EF) echocardiography is clinically still the most used modality to assess LV-EF. We studied whether adding a second-generation microbubble contrast agent could decrease this variability. METHODS AND RESULTS: Forty-eight patients underwent transthoracic echocardiography in second-harmonic mode (SHI) with and without contrast within 5 days after an acute myocardial infarction. LV-EF was determined using the Simpson's biplane method. With contrast intra-observer variability decreased from 12.5 +/- 11.5% to 7.0 +/- 7.0% (P < 0.001) and inter-observer variability decreased from 16.9 +/- 9.9% to 7.0 +/- 6.2% (P < 0.001). Bland-Altman analysis confirmed these findings by demonstrating smaller 95% limits of agreement for both the intra- and inter-observer variability when contrast was used. This improvement in intra- and inter-observer variability was seen to a comparable extent in patients with moderate-to-poor and good quality SHI echocardiograms. CONCLUSION: Echo contrast significantly improves intra- and inter-observer variability for LV-EF, both in patients with moderate-to-poor and good quality SHI echocardiograms. [ABSTRACT FROM AUTHOR]

Methods: The study included 25 hypertrophic cardiomyopathy (HCM) patients (15 non-obstructive and 10 obstructive) and 25 controls for assessment of left atrial (LA) volume, mass and function by two-dimensional echocardiography. Measurement included mean LA diameter (LAD), LA mass = {(mean LAD + anterior LA wall + posterior LA wall)3 - mean LAD3} x 0.8 + 0.6, LA volume = [(8/3 pi L . A1 . A2), where L is LA length, A1 and A2 are LA area in 4-chambers and 2-chambers, respectively] including maximum (V max), minimum (V min), and pre-atrial contraction (V pre-A), total atrial stroke volume (TA-SV), TA emptying fraction (TA-EF), active atrial SV (AA-SV), AA-EF, passive atrial SV (PA-SV), PA-EF, atrial expansion index (AEI), and LA kinetic energy (LA-KE) = (1/2) x AA-SV x P x V2. Results: LAD, LA mass, V max, V min, and V pre-A were significantly higher in HCM than controls. TA-SV and TA-EF were comparable in both HCM subgroups and controls. AA-SV and LA-KE were significantly higher in both HCM subgroups than controls. LA-KE was significantly higher in obstructive HCM than non-obstructive (P < 0.001). PA-EF and AEI were significantly lower in obstructive HCM than controls (P < 0.05). Conclusion: HCM is associated with increased LA size and augmented LA pump function especially obstructive type. LA conduit and reservoir functions are impaired in obstructive HCM. [ABSTRACT FROM AUTHOR]

Abstract

Background: Noncompaction cardiomyopathy (NCCM) is a recently recognized disorder frequently associated with systolic and diastolic heart failures. This study was designed to examine aortic stiffness in NCCM patients and to compare these results to age- and gender-matched controls. Methods: A total of 20 patients with typical echocardiographic features of NCCM (age 38 +/- 16 years, eight males) were investigated. Their results were compared to 20 age- and gender-matched controls. All subjects underwent a complete two-dimensional transthoracic echocardiographic examination. Systolic (SD) and diastolic (DD) ascending aortic diameters were recorded in M-mode at a level of 3 cm above the aortic valve from a parasternal long-axis view. Aortic stiffness index (beta) was calculated as a characteristic of aortic elasticity, as ln(SBP/DBP)/[(SD - DD)/DD], where SBP and DBP are the systolic and diastolic blood pressures, respectively, and ln is the natural logarithm. Results: The number of noncompacted segments in the NCCM patients was 4.6 +/- 2.0. NCCM patients had significantly increased left ventricular dimensions and reduced left ventricular ejection fraction. Compared to controls, aortic stiffness index (beta) was significantly increased in NCCM patients (8.3 +/- 5.2 vs. 3.5 +/- 1.1, p < 0.001). Conclusion: Increased aortic stiffness can be observed in patients with NCCM with moderate to severe heart failure. These alterations may be due to neurohormonal changes in heart failure.

Abstract

Background: The Frank-Starling law describes the relation between left ventricular volume and function. However, only a few studies have described the relation between left atrial volume (LAV) and function. Objective: To describe an LA Frank-Starling law by studying changes in LAV measured by real-time, three-dimensional echocardiography (RT3DE). Methods: LAV was calculated by RT3DE in 70 patients at end-systole (LAV(max)), end-diastole (LAV(min)) and pre-atrial contraction (LAV(pre-A)). According to LAV(max), patients were classified into three groups: LAV(max) <50 ml (group I), LAV(max) 50-70 ml (group II) and LAV(max) >70 ml (group III). Calculated indices of LA pump function were active atrial stroke volume (SV), defined as LAV(pre-A) - LAV(min), and active atrial emptying fraction (EF), defined as active atrial SV/LAV(pre-A) x100% Results: Active atrial SV was significantly higher in group II than in group I (mean (SD) 19.0 (9.2) vs 8.2 (4.9) ml, p<0.0001), in group III it was non-significantly lower than in group II (16.7 (12.5) vs 19.0 (9.2) ml). Active atrial SV correlated well with LAV(pre-A) (r = 0.56, p<0.001), but decreased with larger LAV(pre-A). Active atrial EF tended to be higher in group II than in group I (43.1 (18.2) vs 33.2 (17.5), p<0.10), in group III it was significantly lower than in group II (26.2 (18.5) vs 43.1 (18.2), p<0.01). Conclusion: A Frank-Starling mechanism in the left atrium could be described by RT3DE, shown by an increase in LA contractility in response to an increase in LA preload up to a point, beyond which LA contractility decreased.

Abstract

Objective: To investigate the functional significance of chronotropic incompetence during dobutamine stress echocardiography.Patients and Methods: The functional significance of chronotropic incompetence was evaluated during dobutamine stress echocardiography in 512 patients without beta blocker treatment who underwent dobutamine stress echocardiography (up to 40 microg/kg/min) and completed the protocol or reached the target heart rate. Mean (SD) age was 60 (12) years (313 men, 199 women). Chronotropic incompetence was defined as failure to achieve 85% of the maximum exercise heart rate predicted for age and sex (220 - age in men; 200 - age in women) at maximum dobutamine dose.Results: Chronotropic incompetence occurred in 196 patients (38%). Affected patients were significantly younger, more likely to be men (both p << 0.001) and smokers (p < 0.05), had a higher prevalence of previous myocardial infarction (p < 0.005) and resting wall motion abnormalities (p < 0. 05), and had a lower resting heart rate (p << 0.001) and systolic blood pressure (p << 0.001) than patients without chronotropic incompetence, but there was no difference in the overall prevalence of ischaemia and significant coronary artery disease. By multivariate analysis, independent predictors of chronotropic incompetence were a lower resting heart rate (p << 0.001), younger age (p << 0.001), and male sex (p << 0.001).Conclusions: The relations among sex, age, and chronotropic incompetence show the need to titrate the dobutamine dose using specific data based on age and sex related heart rate responses to dobutamine rather than to an exercise stress test. Obtaining specific heart rate criteria is necessary to determine whether chronotropic incompetence represents a real failure to achieve a normal response or is the result of applying an inappropriate gold standard.

Abstract

The accuracy of dobutamine stress echocardiography (DSE) for the diagnosis of coronary artery disease (CAD) has not been yet evaluated in women. We studied the effect of gender on the accuracy of DSE for the diagnosis of CAD in 306 consecutive patients (210 men and 96 women) with limited exercise capacity and suspected myocardial ischemia who underwent coronary angiography within 3 months of DSE. There were no serious complications during DSE. Men had a higher prevalence of nonsustained ventricular tachycardia (7% vs 0.03%, p <0.05) and supraventricular tachycardia (9% vs 0.03%, p <0.05) during the test compared with women. Peak stress rate-pressure product was not different in men and women (18,140 +/- 4,187 vs 18,543 +/- 4,223). Significant CAD (> or =50% luminal diameter stenosis) was present in 171 men (81%) and in 62 women (65%, p <0.005). The sensitivity, specificity, and accuracy of ischemic pattern at DSE for the diagnosis of significant CAD were 76% (confidence interval [CI] 67 to 84), 94% (CI 89 to 99), and 82% (CI 75 to 90) in women and 73% (CI 67 to 79), 77% (CI 71 to 83), and 74% (CI 68 to 80) in men, respectively. Overall specificity was higher in women than in men (p <0.05). Regional accuracy of DSE was significantly higher in women than in men in the 3 arterial regions (84% [CI 79 to 88] vs 75% [CI 72 to 79], p <0.005). It is concluded that DSE is a safe and feasible method for the diagnosis of CAD in women. The overall specificity and the regional accuracy of DSE are higher in women than in men. Further studies are required to evaluate the functional significance of these findings and their reproducibility in different patient populations. [ABSTRACT FROM AUTHOR]

Abstract

Background: The size of the transcatheter heart valves (THV) is overestimated up to 20% based on aortic annulus diameter measured using computed tomography (CT). However, the prosthesis may not be fully expanded during implantation. THV underexpansion might have detrimental clinical consequences. Purpose The aim of this study was to define the degree of underexpansion degree of different THVs after implantation, introduced as the shrinking index. Methods: In total we enrolled 114 patients (68 men, 79 ± 8 years old) who underwent transcatheter aortic valve implantation (TAVI) with the self-expanding CoreValve (n=28 patients), mechanically expanded Lotus valve (n= 37) or balloon expandable Edwards SAPIEN XT (n=18) and Edwards SAPIEN 3 (n= 31). The cover index of the THV was calculated as the percentage difference of the nominal prosthesis size and annulus diameter measured using CT. Intraprocedural transesophageal echocardiography (TEE) was performed to determine the size of the THV inflow after implantation. The shrinking index was calculated as the percentage of the difference between the inflow size by TEE and the nominal prosthesis size divided by prosthesis size. Results: Cover index per CT assessment before TAVI was 18 ± 7% for CoreValve, 2 ± 4% for Lotus, 9 ± 5% for Edwards SAPIEN and 4 ± 5% for Edwards SAPIEN 3 (ANOVA p < 0.001, Corevalve was significantly larger than the others). Compared with aortic annulus diameter measured using TEE in long axis view, the overestimation increased to 28 ± 9% for CoreValve, 12 ± 8% for Lotus, 18 ± 12% for Edwards SAPIEN and 12 ± 8% for Edwards SAPIEN 3 (ANOVA p < 0.001, Corevalve was significantly larger than the others). Conversely, the shrinking index after TAVI was -31 ± 6% for CoreValve, -20 ± 5% for Lotus, -22 ± 6% for SAPIEN XT and -19 ± 5% for SAPIEN 3 (ANOVA p < 0.001, Corevalve was significantly larger than the others). The interobserver variability (relative difference) of TEE in measuring the aortic annulus and prosthesis inflow was 6 ± 5% and 7 ± 5% respectively. Conclusion: The shrinking index determines the degree of THV underexpansion after TAVI and can be reliably measured with TEE. The self-expanding CoreValve tended to be under-expanded the most, indicated by the largest shrinking index, while the under-expansion degree was comparable between Lotus valve, SAPIEN XT and SAPIEN 3. The clinical implications of the shrinking index requires further study.

Abstract

Purpose: Epicardial adipose tissue (EAT) thickness, measured by echocardiography, is associated to the presence of coronary artery disease (CAD) and severe aortic stenosis (AS). EAT thickness is commonly referred as the diameter of the echo-free space between the right ventricular wall and the visceral layer of the pericardium in parasternal long axis view, using the aortic annulus as an anatomic landmark (EAT-1). We aimed to demonstrate that the direct measurement of the adipose tissue thickness visualized in the space between the ascending aorta and the right ventricle (EAT-2) might be considered an alternative method. Methods: We measured EAT-1 and EAT-2 in 130 pts with severe cardiac disease referred for cardiac surgery: 53 pts with isolated AS, 49 pts with severe CAD, and 28 pts with both severe AS and CAD (AS+CAD); and in 50 control subjects matched for age, sex and BMI. The two measurements were obtained at end-systole in 3 cardiac cycles (figure). Results. Both EAT-1 and EAT-2 measurements had an excellent reproducibility. With respect to controls pts had significantly increased EAT-1 (2,4 ± 0,5mm vs 6 ± 2mm; p<0,05) and EAT-2 (3 ± 1,2mm vs 12 ± 3mm; p<0,05). EAT-1 and EAT-2 were not statistically different in controls. EAT-2 was significantly higher than EAT-1 in CAD, AS, and AS+CAD pts (p<0,05). Interestingly, EAT-2, but not EAT-1, was significantly increased in AS+CAD pts with respect to EAT-2 of pts with isolated AS and isolated CAD. Conclusions: Our data demonstrate that EAT-2, as well as EAT-1, is a valuable method to measure EAT thickness. Further, EAT-2 seems to better recognize EAT increase, in pts with AS+CAD. Comprehensively, EAT-2 is greater than EAT-1. The larger space between ascending aorta and right ventricle, allowing EAT expansion, could justify our observation.

Abstract

Background: Mitral annulus (MA) remodeling was suggested to have a role in the occurrence of mitral valve (MV) leaflet flail in pts with organic mitral regurgitation (OMR). Aim: To assess the extent of MA remodeling and dysfunction in relation to the severity of MV disease in pts with OMR. Methods: We acquired 3D full-volumes of the MA and left ventricle (LV) in 52 pts (57 ± 15 yrs, 34 men) with OMR (40 pts with posterior mitral prolapse, 12 pts with Barlow disease), and in sinus rhythm. MV morphology was assessed using both en-face view of volume rendered images and longitudinal slices of the datasets. MA size and function were automatically assessed during cardiac systole (MV assessment 2.3, TomTec). LV volumes and ejection fraction (LVEF) were measured with AutoLVQ (Echopac BT 12, GE). Results: 14 pts showed a flail of the MV, and 38 pts MV prolapse without flail. LVEF, MA displacement and MA size and geometry were similar in pts with and without MV flail (Table). Conversely, MA fractional area change was significantly decreased in pts with leaflet flail. Binary logistic regression showed that decreased MA fractional area change was associated with the presence of leaflet flail (β=0.20, p=0.02). Conclusions: In pts with OMR and normal LV function, the contractile dysfunction of the MA, and not the size of the MA, is associated with the presence of leaflet flail. Further studies are needed to assess if the MA contractile dysfunction precedes or is a consequence of the occurrence of MV flail.

Abstract

Clinical PET acquisitions of the heart suffer from artefacts and drops in image quality due to the poor spatial resolution of the PET system. Moreover, cardiac PET images are further degraded by the blur caused by the breathing and beating motions, thus hampering diagnosis and evaluation of myocardial pathologies. Anatomy-enhanced PET reconstruction, using a high-resolution CT, has proven useful in brain imaging. In cardiac datasets however, due to the motion artefacts, the application of any restoring technique on datasets affected by motion blur needs to be preceded by the validation of the proposed method on realistic static datasets. In this work, the validation is performed using static cardiac ex vivo datasets obtained from a number of sacrificed sheep, scanned on a clinical PET/CT scanner. The aim of this work is to assess the effectiveness of reconstructions of the acquired datasets with different CT-based anatomical priors, in comparison to reconstructions currently applied in clinical practise. The gold standard to which all reconstructions are compared consists of images of the same hearts scanned on a small-animal PET scanner, whose high spatial resolution allows for almost artefact-free images. Encouraging results were obtained so far, with improvements in volume delineation and uniformity of activity values when anatomical information was used. Fig 1 shows the gold standard image (left) compared to a regular clinical reconstruction (middle) and to a reconstruction using the high-resolution CT as anatomical information (right). Figure

Abstract

Purpose: Atrial fibrillation (AF) is the most prevalent sustained arrhythmia. It is a disease of the elderly and it is common in patients (pts) with structural heart disease. Hypertension (HA), hypertensive heart disease (HHD), diabetes mellitus (DM), coronary artery disease (CAD), heart failure (HF), and valvular heart disease (VHD) are recognized predisposing factors to AF. Objectives: To echocardiographicly disclose the most common predisposing morbidities to AF in our population sample. Methods: From June 2000 to February 2013, 3755 consecutive pts with AF were studied during echocardiographic check-up. According to transthoracic echo, pts were divided in groups based on dominative underlying heart diseases. Electrocardiographically documented AF was subdivided in two groups: transitory and chronic. Transitory AF fulfilled criteria for paroxysmal or persistent AF. Chronic AF were cases of long-standing persistent or permanent AF. Results: The median age was 72 years, age range between 16 and 96 years. There were 51.4% of females. Chronic AF was observed in 68.3% pts. Distribution of underlying heart diseases is shown in figure. Lone AF was diagnosed in only 25 pts, mostly in younger males (median age 48 years, range 29–59, men 80%). Chronic AF was predominant in groups with advanced cardiac remodeling such as dilatative cardiomyopaty (DCM) and VHD, mostly in elderly. HA and DM were found in 75.4% and 18.8%, respectively. Almost 1/2 of pts with AF had HF and 59.2% had diastolic HF. Conclusion: Up to now, echocardiographic categorization of the predisposing factors to AF was not reported. Echocardiographic evaluation of patients with AF could facilitate in identification and well-timed treatment of predisposing comorbidites. Figure Etiological distribution of AF

Abstract

Purpose: Cardiac deconditioning due to immobilization is a risk factor for cardiovascular disease. The physiology of cardiac adaptation to deconditioning has not been fully elucidated. The purpose of the present study was to assess the effects of 21-days of strict head-down (-6 degrees) bed-rest (BR) deconditioning on left ventricular (LV) dimensions and mass measured by MRI. Methods: Ten healthy men (mean age 32±6) were enrolled; the experiment was conducted at DLR (Koln, Germany) as part of the European Space Agency BR studies. Steady-state free precession MRI images (7mm thickness, no gap, no overlap) were obtained (Symphony 1.5T, Siemens) in a stack of short-axis views from LV base to LV apex, before (PRE), at the end of BR (HDT20), and four days after the BR conclusion (POST). Endocardial and epicardial semi-automated contouring was performed using freely available software (Segment). Results: At HDT20, significant reductions in LV mass (16%), end-diastolic (26%) and end-systolic (27%) volumes and stroke volume (27%) were observed, while ejection fraction did not change. These changes were accompanied by a measured decrease (14%) in plasma and blood volume (by gas-rebreathing technique), as well as by a significant reduction (14%) in VO2max aerobic power, measured using a graded cycle ergometer test protocol to volitional fatigue, at one day after the BR conclusion, while expiratory exchange ratio did not change. At POST, LV volumes were restored, while LV mass was still trending towards control values. Conclusions: Cardiac adaptation to deconditioning affected LV mass and dimensions, as a combined result of LV remodeling and fluids loss, accompanied by worsening in aerobic power. This should be taken into account in patients with cardiovascular diseases, when immobilized in bed, to proper adjust the therapy, or to define appropriate physical exercises when possible, in order to avoid further complications.   Cardiac MRI parameters PREHDT20POSTLV mass (g)121±6102±11*114±16End-diastolic volume (ml)119±2590±14*118±25End-systolic volume (ml)42±831±8*45±14Stroke volume (ml)76±2259±11*73±15Ejection fraction (%)64±665±762±7 *: p<.01 vs PRE (one-way Anova for paired data and Tukey test)

Abstract

Background: In patients with low-gradient aortic stenosis (AS) and low transvalvular flow, dobutamine stress echocardiography (DSE) is recommended to determine AS severity, whereas the degree of aortic valve calcification (AVC) supposedly correlates with AS severity according to current European and American guidelines., Objectives: The purpose of this study was to assess the relationship between AVC and AS severity as determined using echocardiography and DSE in patients with aortic valve area <1 cm 2 and peak aortic valve velocity <4.0 m/s., Methods: All patients underwent DSE to determine AS severity and multislice computed tomography to quantify AVC. Receiver-operating characteristics curve analysis was used to assess the diagnostic value of AVC for AS severity grading as determined using echocardiography and DSE in men and women., Results: A total of 214 patients were included. Median age was 78 years (25th-75th percentile: 71-84 years) and 25% were women. Left ventricular ejection fraction was reduced (<50%) in 197 (92.1%) patients. Severe AS was diagnosed in 106 patients (49.5%). Moderate AS was diagnosed in 108 patients (50.5%; in 77 based on resting transthoracic echocardiography, in 31 confirmed using DSE). AVC score was high (≥2,000 for men or ≥1,200 for women) in 47 (44.3%) patients with severe AS and in 47 (43.5%) patients with moderate AS. AVC sensitivity was 44.3%, specificity was 56.5%, and positive and negative predictive values for severe AS were 50.0% and 50.8%, respectively. Area under the receiver-operating characteristics curve was 0.508 for men and 0.524 for women., Conclusions: Multi-slice computed tomography-derived AVC scores showed poor discrimination between grades of AS severity using DSE and cannot replace DSE in the diagnostic work-up of low-gradient severe AS., Competing Interests: Funding Support and Author Disclosures Dr Van Mieghem has received grant support/research contracts from Abbott Vascular, Boston Scientific, Medtronic, Edwards Lifesciences, Daiichy Sankyo, AstraZeneca, and PulseCath BV; and has received consulting/speaker fees from Abbot Vascular, Boston Scientific Corporation, Medtronic, Daiichy Sankyo, PulseCath BV, JenaValve, and Amgen.

Abstract

Inter-echocardiography core laboratory (ECL) harmonization is pivotal to consider data from different ECLs interchangeable. On the basis of the experience of the first trans-Atlantic harmonization of 2 established ECLs in the field of transcatheter aortic valve replacement (TAVR) trials, this review describes the harmonized ECL methodology in analyzing and adjudicating the post-TAVR echocardiographic endpoints according to Valve Academic Research Consortium 3 definitions. This review presents the feasibility and intra- and inter-ECL reproducibility, explains the root cause of potential important inter-ECL variability, and formulates ECL recommendations for optimal post-TAVR echocardiographic image acquisition. The implementation of inter-ECL harmonization may further define the best practice of ECLs and have logistic and regulatory implications for the realization of future TAVR trials., Competing Interests: Funding Support and Author Disclosures This study was self-funded by the participating institutions.

40. Moderate Aortic Stenosis-Advanced Imaging, Risk Assessment, and Treatment Strategies.

Author

Abstract

Moderate aortic stenosis is increasingly recognized as a disease entity with poor prognosis. Diagnosis of moderate aortic stenosis may be complemented by laboratory tests and advanced imaging techniques focused at detecting signs of cardiac damage such as increase of cardiac enzymes (N-terminal pro-B-type Natriuretic Peptide, troponin), left ventricular remodeling (hypertrophy, reduced left ventricular ejection fraction), or myocardial fibrosis. Therapy should include guideline-directed optimal medical therapy for heart failure. Patients with signs of cardiac damage may benefit from early intervention, which is the focus of several ongoing randomized controlled trials. As yet, no evidence-based therapy exists to halt the progression of aortic valve calcification., Competing Interests: Nicolas M. Van Mieghem has received grant support/research contracts from Abbott Vascular, Boston Scientific, Medtronic, Edwards Lifesciences, Daiichy Sankyo, Astra Zeneca and PulseCath BV and has received consulting/speaker fees from Abbot Vascular, Boston Scientific Corporation, Medtronic, Daiichy Sankyo, PulseCath BV, JenaValve, and Amgen.

Abstract

Left ventricular outflow tract obstruction (LVOTO) is a notorious complication of transcatheter mitral valve replacement (TMVR). Computed tomography-derived simulations can predict neo-LVOTO post-TMVR, whereas alcohol septal ablation (ASA) can mitigate neo-LVOTO risk. We report a case of sequential ASA of 2 adjacent septal branches to resolve unexpected neo-LVOTO post-TMVR., Competing Interests: Dr Van Mieghem has received grants or contracts from Abbott, Boston Scientific, Biotronik, Edwards Lifesciences, Medtronic, PulseCath BV, Abiomed, and Daiichi Sankyo; consulting fees from JenaValve, Daiichi Sankyo, Abbott, Boston Scientific, and Medtronic; payment or honoraria for lectures, presentations, speakers, manuscripts, and educational events from Abiomed and Amgen; and support for attending meetings and/or travel from JenaValve.

Abstract

Objective: Previously published results of the OPTICARE XL open label randomized controlled trial showed no added value of OPTICARE XL CR, a dedicated cardiac rehabilitation (CR) program for patients with obesity, with respect to health-related quality of life (primary outcome). This clinical trial studied the effects of OPTICARE XL CR on several secondary outcomes, which included body weight, physical activity, sedentary behavior, and physical fitness., Methods: Patients with coronary artery disease or atrial fibrillation and body mass index ≥ 30 were randomized to OPTICARE XL CR (n = 102) or standard CR (n = 99). OPTICARE XL CR was a 1-year group intervention, specifically designed for patients with obesity that included aerobic and strength exercise, behavioral coaching, and an aftercare program. Standard CR consisted of a 6- to 12-week group aerobic exercise program, supplemented with cardiovascular lifestyle education. Study end points included body weight, physical activity, sedentary behavior (accelerometer), and physical fitness (6-Minute Walk Test and handgrip strength), which were evaluated 6 months after the end of CR (primary endpoint) and 3 months after the start of CR., Results: Six months after completion of either program, improvements in body weight, physical activity, sedentary behavior, and physical fitness were similar between the groups. Three months after CR start, patients randomized to OPTICARE XL CR showed greater weight loss (mean change = -3.6 vs -1.8 kg) and a larger improvement in physical activity (+880 vs +481 steps per day) than patients randomized to standard CR., Conclusion: Patients allocated to OPTICARE XL CR lost significantly more body weight and showed promising results with respect to physical activity 3 months after the start of CR; however, these short-term results were not expanded or sustained in the longer term., Impact: Patients with obesity do not benefit from standard CR programs. The new OPTICARE XL CR program showed its effects in the short term on weight loss and physical activity, and, therefore, redesign of the aftercare phase is recommended., (© The Author(s) 2023.

Abstract

Aims: In a large proportion of heart failure with reduced ejection fraction (HFrEF) patients, echocardiographic estimation of left atrial pressure (LAP) is not possible when the ratio of the peak early left ventricular filling velocity over the late filling velocity (E/A ratio) is not available, which may occur due to several potential causes. Left atrial reservoir strain (LASr) is correlated with LV filling pressures and may serve as an alternative parameter in these patients. The aim of this study was to determine whether LASr can be used to estimate LAP in HFrEF patients in whom E/A ratio is not available., Methods and Results: Echocardiograms of chronic HFrEF patients were analysed and LASr was assessed with speckle tracking echocardiography. LAP was estimated using the current ASE/EACVI algorithm. Patients were divided into those in whom LAP could be estimated using this algorithm (LAPe) and into those in whom this was not possible because E/A ratio was not available (LAPne). We assessed the prognostic value of LASr on the primary endpoint (PEP), which comprised the composite of hospitalization for the management of acute or worsened HF, left ventricular assist device implantation, cardiac transplantation, and cardiovascular death, whichever occurred first in time. We studied 153 patients with a mean age of 58 years of whom 76% men and 82% who were in NYHA class I-II. A total of 86 were in the LAPe group and 67 in the LAPne group. LASr was significantly lower in the LAPne group as compared with the LAPe group (15.8% vs. 23.8%, P < 0.001). PEP-free survival at a median follow-up of 2.5 years was 78% in LAPe versus 51% in LAPne patients. An increase in LASr was significantly associated with a reduced risk of the PEP in LAPne patients (adjusted hazard ratio: 0.91 per %, 95% confidence interval 0.84-0.98). An abnormal LASr (<18%) was associated with a five-fold increase in reaching the PEP., Conclusions: In HFrEF patients in whom echocardiographic estimation of LAP is not possible due to due to unavailability of E/A ratio, assessing LASr potentially carries added clinical and prognostic value., (© 2023 The Authors.

Abstract

Objectives: Renal sympathetic denervation (RDN) reduces blood pressure (BP). However, one out of three patients does not exhibit a significant BP response to the therapy. This study investigates the association between noninvasive vascular stiffness indices and RDN-mediated BP reduction., Methods: In this prospective, single-arm pilot study, patients with systolic office BP at least 140 mmHg, mean 24-h systolic ambulatory blood pressure (ABP) at least 130 mmHg and at least three prescribed antihypertensive drugs underwent radiofrequency RDN. The primary efficacy endpoint was temporal evolution of mean 24-h systolic ABP throughout 1-year post RDN (measured at baseline and 3-6-12 months). Effect modification was studied for baseline ultrasound carotid-femoral and magnetic resonance (MR) pulse wave velocity (PWV), MR aortic distensibility, cardiac MR left ventricular parameters and clinical variables. Statistical analyses were performed using linear mixed-effects models, and effect modification was assessed using interaction terms., Results: Thirty patients (mean age 62.5 ± 10.7 years, 50% women) with mean 24-h ABP 146.7/80.8 ± 13.7/12.0 mmHg were enrolled. Following RDN, mean 24-h systolic ABP changed with -8.4 (95% CI: -14.5 to -2.3) mmHg/year ( P  = 0.007). Independent effect modifiers were CF-PWV [+2.7 (0.3 to 5.1) mmHg/year change in outcome for every m/s increase in CF-PWV; P  = 0.03], daytime diastolic ABP [-0.4 (-0.8 to 0.0) mmHg/year per mmHg; P  = 0.03], age [+0.6 (0.2 to 1.0) mmHg/year per year of age; P  = 0.006], female sex [-14.0 (-23.1 to -5.0) mmHg/year as compared with men; P  = 0.003] and BMI [+1.2 (0.1 to 2.2) mmHg/year per kg/m 2 ; P  = 0.04]., Conclusion: Higher CF-PWV at baseline was associated with a smaller reduction in systolic ABP following RDN. These findings could contribute to improve identification of RDN responders., (Copyright © 2023 The Author(s). Published by Wolters Kluwer Health, Inc.)

Abstract

Background: We investigated whether repeatedly measured global longitudinal strain (GLS) has incremental prognostic value over repeatedly measured left ventricular ejection fraction (LVEF) and N-terminal pro B-type natriuretic peptide (NT-proBNP), and a single "baseline" GLS value, in chronic heart failure (HF) patients., Methods: In this prospective observational study, echocardiography was performed in 173 clinically stable chronic HF patients every six months during follow up. During a median follow-up of 2.7 years, a median of 3 (25th-75th percentile:2-4) echocardiograms were obtained per patient. The endpoint was a composite of HF hospitalization, left ventricular assist device, heart transplantation, cardiovascular death. We compared hazard ratios (HRs) for the endpoint from Cox models (used to analyze the first available GLS measurements) with HRs from joint models (which links repeated measurements to the time-to-event data)., Results: Mean age was 58 ± 11 years, 76% were men, 81% were in New York Heart Association functional class I/II, and all had LVEF < 50% (mean ± SD: 27 ± 9%). The endpoint was reached by 53 patients. GLS was persistently decreased over time in patients with the endpoint. However, temporal GLS trajectories did not further diverge in patients with versus without the endpoint and remained stable during follow-up. Both single measurements and temporal trajectories of GLS were significantly associated with the endpoint [HR per SD change (95%CI): 2.15(1.34-3.46), 3.54 (2.01-6.20)]. In a multivariable model, repeatedly measured GLS maintained its prognostic value while repeatedly measured LVEF did not [HR per SD change (95%CI): GLS:4.38 (1.49-14.70), LVEF:1.14 (0.41-3.23)]. The association disappeared when correcting for repeatedly measured NT-proBNP., Conclusion: Temporal evolution of GLS was associated with adverse events, independent of LVEF but not independent of NT-proBNP. Since GLS showed decreased but stable values in patients with adverse prognosis, single measurements of GLS provide sufficient information for determining prognosis in clinical practice compared to repeated measurements, and temporal GLS patterns do not add prognostic information to NT-proBNP., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Abou Kamar, Aga, de Bakker, van den Berg, Strachinaru, Bowen, Frowijn, Akkerhuis, Brugts, Manintveld, Umans, Geleijnse, Boersma, van Dalen and Kardys.)

46. Reclassification of aortic stenosis by fusion of echocardiography and computed tomography in low-gradient aortic stenosis.

Author

Abstract

Background: The integration of computed tomography (CT)-derived left ventricular outflow tract area into the echocardiography-derived continuity equation results in the reclassification of a significant proportion of patients with severe aortic stenosis (AS) into moderate AS based on aortic valve area indexed to body surface area determined by fusion imaging (fusion AVA i ). The aim of this study was to evaluate AS severity by a fusion imaging technique in patients with low-gradient AS and to compare the clinical impact of reclassified moderate AS versus severe AS., Methods: We included 359 consecutive patients who underwent transcatheter aortic valve implantation for low-gradient, severe AS at two academic institutions and created a joint database. The primary endpoint was a composite of all-cause mortality and rehospitalisations for heart failure at 1 year., Results: Overall, 35% of the population (n = 126) were reclassified to moderate AS [median fusion AVAi 0.70 (interquartile range, IQR 0.65-0.80) cm 2 /m 2 ] and severe AS was retained as the classification in 65% [median fusion AVAi 0.49 (IQR 0.43-0.54) cm 2 /m 2 ]. Lower body mass index, higher logistic EuroSCORE and larger aortic dimensions characterised patients reclassified to moderate AS. Overall, 57% of patients had a left ventricular ejection fraction (LVEF) <50%. Clinical outcome was similar in patients with reclassified moderate or severe AS. Among patients reclassified to moderate AS, non-cardiac mortality was higher in those with LVEF <50% than in those with LVEF ≥50% (log-rank p = 0.029)., Conclusions: The integration of CT and transthoracic echocardiography to obtain fusion AVAi led to the reclassification of one third of patients with low-gradient AS to moderate AS. Reclassification did not affect clinical outcome, although patients reclassified to moderate AS with a LVEF <50% had worse outcomes owing to excess non-cardiac mortality., (© 2020. The Author(s).)

Abstract

Introduction: The aim of the present study was to assess the safety and efficacy of renal sympathetic denervation (RDN) in patients with heart failure with reduced ejection fraction (HFrEF)., Methods: We randomly assigned 50 patients with a left ventricular ejection fraction (LVEF) ≤ 35% and NYHA class ≥ II, in a 1:1 ratio, to either RDN and optimal medical therapy (OMT) or OMT alone. The primary safety endpoint was the occurrence of a combined endpoint of cardiovascular death, rehospitalisation for heart failure, and acute kidney injury at 6 months. The primary efficacy endpoint was the change in iodine-123 meta-iodobenzylguanidine ( 123 I‑MIBG) heart-to-mediastinum ratio (HMR) at 6 months., Results: Mean age was 60 ± 9 years, 86% was male and mean LVEF was 33 ± 8%. At 6 months, the primary safety endpoint occurred in 8.3% vs 8.0% in the RDN and OMT groups, respectively (p = 0.97). At 6 months, the mean change in late HMR was -0.02 (95% CI: -0.08 to 0.12) in the RDN group, versus -0.02 (95% CI: -0.09 to 0.12) in the OMT group (p = 0.95) whereas the mean change in washout rate was 2.34 (95% CI: -6.35 to 1.67) in the RDN group versus -2.59 (95% CI: -1.61 to 6.79) in the OMT group (p-value 0.09)., Conclusion: RDN with the Vessix system in patients with HFrEF was safe, but did not result in significant changes in cardiac sympathetic nerve activity at 6 months as measured using 123 I‑MIBG., (© 2021.

Abstract

Background: Functional mitral regurgitation (FMR) can be subclassified on the basis of its proportionality relative to left ventricular (LV) volume and function, indicating potential differences in underlying etiology. The aim of this study was to evaluate the association of FMR proportionality with FMR reduction, heart failure hospitalization and mortality after transcatheter edge-to-edge mitral valve repair (TEER)., Methods: This multicenter registry included 241 patients with symptomatic heart failure with reduced LV ejection fraction treated with TEER for moderate to severe or greater FMR. FMR proportionality was graded on preprocedural transthoracic echocardiography using the ratio of the effective regurgitant orifice area to LV end-diastolic volume. Baseline characteristics, follow-up transthoracic echocardiography, and 2-year clinical outcomes were compared between groups., Results: Median LV ejection fraction, effective regurgitant orifice area and LV end-diastolic volume index were 30% (interquartile range [IQR], 25%-35%), 27 mm 2 , and 107 mL/m 2 (IQR, 90-135 mL/m 2 ), respectively. Median effective regurgitant orifice area/LV end-diastolic volume ratio was 0.13 (IQR, 0.10-0.18). Proportionate FMR (pFMR) and disproportionate FMR (dFMR) was present in 123 and 118 patients, respectively. Compared with patients with pFMR, those with dFMR had higher baseline LV ejection fractions (median, 32% [IQR, 27%-39%] vs 26% [IQR, 22%-33%]; P < .01). Early FMR reduction with TEER was more pronounced in patients with dFMR (odds ratio, 0.45; 95% CI, 0.28-0.74; P < .01) than those with pFMR, but not at 12 months (odds ratio, 0.93; 95% CI, 0.53-1.63; P = .80). Overall, in 35% of patients with initial FMR reduction after TEER, FMR deteriorated again at 1-year follow-up. Rates of 2-year all-cause mortality and heart failure hospitalization were 30% (n = 66) and 37% (n = 76), with no differences between dFMR and pFMR., Conclusions: TEER resulted in more pronounced early FMR reduction in patients with dFMR compared with those with pFMR. Yet after initial improvement, FMR deteriorated in a substantial number of patients, calling into question durable mitral regurgitation reductions with TEER in selected patients. The proportionality framework may not identify durable TEER responders., (Copyright © 2021 American Society of Echocardiography. Published by Elsevier Inc. All rights reserved.)

Abstract

Background: Functional mitral regurgitation (FMR) can be subclassified based on its proportionality relative to left ventricular function and end-diastolic volume. FMR proportionality could help identify responders to transcatheter edge-to-edge mitral valve repair (MitraClip) in terms of residual FMR and/or clinical improvement., Methods: This single-centre retrospective cohort study evaluated the feasibility of determining FMR proportionality in symptomatic heart failure patients with reduced left ventricular function who were treated with MitraClip for ≥ moderate-to-severe FMR. Baseline proportionate (pFMR) and disproportionate FMR (dFMR) were distinguished. Patient characteristics and MitraClip procedural outcomes were described., Results: From an overall cohort of 81 eligible FMR patients, 23/81 (28%) had to be excluded due to missing transthoracic echocardiogram parameters, 22/81 were excluded based on FMR severity. The remaining cohort, of 36/81 patients (44%), could be classified into dFMR (n = 26) or pFMR (n = 10). Conduction disorders were numerically increased in dFMR. All cases requiring > 2 clips were in the dFMR group and absence of FMR reduction occurred more frequently with dFMR., Point of View/conclusion: Important limitations in terms of imaging acquisition affect the translation of the FMR proportionality concept to a real-world data set. We did observe different demographic and FMR response patterns in patients with proportionate and disproportionate FMR that warrant further investigation., (© 2021. The Author(s).)

Abstract

Background: The study investigators previously reported that moderate aortic stenosis (AS) is associated with a poor prognosis in patients with heart failure (HF) with reduced left ventricular ejection fraction (LVEF) (HFrEF). However, the respective contribution of moderate AS versus HFrEF to the outcomes of these patients is unknown., Objectives: This study sought to determine the impact of moderate AS on outcomes in patients with HFrEF., Methods: The study included 262 patients with moderate AS (aortic valve area >1.0 and <1.5 cm 2 ; and peak aortic jet velocity >2 and <4 m/s, at rest or after dobutamine stress echocardiography) and HFrEF (LVEF <50%). These patients were matched 1:1 for sex, age, estimated glomerular filtration rate, New York Heart Association functional class III to IV, presence of diabetes, LVEF, and body mass index with patients with HFrEF but no AS (i.e., peak aortic jet velocity <2 m/s). The endpoints were all-cause mortality and the composite of death and HF hospitalization., Results: A total of 262 patients with HFrEF and moderate AS were matched with 262 patients with HFrEF and no AS. Mean follow-up was 2.9 ± 2.2 years. In the moderate AS group, mean aortic valve area was 1.2 ± 0.2 cm 2 , and mean gradient was 14.5 ± 4.7 mm Hg. Moderate AS was associated with an increased risk of mortality (hazard ratio [HR]: 2.98; 95% confidence interval [CI]: 2.08 to 4.31; p < 0.0001) and of the composite of HF hospitalization and mortality (HR: 2.34; 95% CI: 1. 72 to 3.21; p < 0.0001). In the moderate AS group, aortic valve replacement (AVR) performed in 44 patients at a median follow-up time of 10.9 ± 16 months during follow-up was associated with improved survival (HR: 0.59; 95% CI: 0.35 to 0.98; p = 0.04). Notably, surgical AVR was not significantly associated with improved survival (p = 0.92), whereas transcatheter AVR was (HR: 0.43; 95% CI: 0.18 to 1.00; p = 0.05)., Conclusions: In this series of patients with HFrEF, moderate AS was associated with a marked incremental risk of mortality. AVR, and especially transcatheter AVR during follow-up, was associated with improved survival in patients with HFrEF and moderate AS. These findings provide support to the realization of a randomized trial to assess the effect of early transcatheter AVR in patients with HFrEF and moderate AS., Competing Interests: Funding Support and Author Disclosures The Department of Cardiology of the Erasmus Medical Center Rotterdam has received research grants from Claret Medical, Boston Scientific, Medtronic, and Edwards Lifesciences.
