RESUMO

Tricuspid regurgitation (TR) secondary to cardiac implantable electronic devices (CIEDs) has been well documented and is associated with worse cardiovascular outcomes. A variety of mechanisms have been proposed including lead-induced mechanical disruption of the tricuspid valvular or subvalvular apparatus and pacing-induced electrical dyssynchrony. Patient characteristics such as age, sex, baseline atrial fibrillation, and pre-existing TR have not been consistent predictors of CIED-induced TR. While two-dimensional echocardiography is helpful in assessing the severity of TR, three-dimensional echocardiography has significantly improved accuracy in identifying the etiology of TR and whether lead position contributes to TR. Three-dimensional echocardiography may therefore play a future role in optimizing lead positioning during implant to reduce the risk of CIED-induced TR. Optimal lead management strategies in addition to percutaneous interventions and surgery in alleviating TR are very important.

RESUMO

AIMS: The aim of this study was to define the natural history of patients with mitral annular calcification (MAC)-related mitral valve dysfunction and to assess the prognostic importance of mean transmitral pressure gradient (MG) and impact of concomitant mitral regurgitation (MR). METHODS AND RESULTS: The institutional echocardiography database was examined from 2001 to 2019 for all patients with MAC and MG ≥3 mmHg. A total of 5754 patients were stratified by MG in low (3-5 mmHg, n = 3927), mid (5-10 mmHg, n = 1476), and high (≥10 mmHg, n = 351) gradient. The mean age was 78 ± 11 years, and 67% were female. MR was none/trace in 32%, mild in 42%, moderate in 23%, and severe in 3%. Primary outcome was all-cause mortality, and outcome models were adjusted for age, sex, and MAC-related risk factors (hypertension, diabetes, coronary artery disease, chronic kidney disease). Survival at 1, 5, and 10 years was 77%, 42%, and 18% in the low-gradient group; 73%, 38%, and 17% in the mid-gradient group; and 67%, 25%, and 11% in the high-gradient group, respectively (log-rank P < 0.001 between groups). MG was independently associated with mortality (adjusted HR 1.064 per 1 mmHg increase, 95% CI 1.049-1.080). MR severity was associated with mortality at low gradients (P < 0.001) but not at higher gradients (P = 0.166 and 0.372 in the mid- and high-gradient groups, respectively). CONCLUSION: In MAC-related mitral valve dysfunction, mean transmitral gradient is associated with increased mortality after adjustment for age, sex, and MAC-related risk factors. Concomitant MR is associated with excess mortality in low-gradient ranges (3-5 mmHg) but gradually loses prognostic importance at higher gradients, indicating prognostic utility of transmitral gradient in MAC regardless of MR severity.

RESUMO

BACKGROUND: Cardiac resynchronization therapy (CRT) improves left heart geometry and function in nonischemic cardiomyopathy (NICMP). We aimed to detail the effects of CRT on left ventricular (LV) and mitral valve (MV) remodeling using 2-dimensional transthoracic echocardiography. METHODS: Forty-five consecutive patients with NICMP who underwent CRT implantation between 2009 and 2012, and had pre-CRT and follow-up echocardiograms available, were included. Paired t test, linear and logistic regression, and Kaplan-Meier survival analyses were used for statistical assessment. RESULTS: The mean age and QRS duration were 60 years and 157 ms, respectively, and 13 (28.9%) were female. At a mean follow-up of 3 years, there were 22 (48.9%) "CRT responders" (≥15% reduction in LV end-systolic volume index [LVESVi]). Significant improvements were observed in LV ejection fraction (26.3% vs 34.3%) and LVESVi (87.7 vs 71.1 mL/m2 ), as well as mitral regurgitation vena contracta width, MV tenting height and area, and end-systolic interpapillary muscle distance. Five-year actuarial survival was 87.5%. Multivariate regression analyses revealed the pre-CRT LVESVi (ß = 0.52), and MV coaptation length (ß = -0.34) and septolateral annular diameter (ß = 0.25) as good correlates of follow-up LVESVi. Variables associated with CRT response were pre-CRT MV coaptation length (OR 1.75, 95% CI 1.0-3.1) and posterior leaflet tethering angle (OR 1.07, 95% CI 1.0-1.14), irrespective of baseline QRS morphology and duration (all P < .05). CONCLUSIONS: Cardiac resynchronization therapy improves LV and MV geometry and function in half of patients with NICMP, which is paralleled by decreased mitral regurgitation severity. The extent of pre-CRT LV remodeling and MV tethering are associated with CRT response.

RESUMO

BACKGROUND: Secondary mitral regurgitation (MR) is common in patients with left bundle branch block (LBBB) undergoing cardiac resynchronization therapy (CRT). We aimed to define CRT effects on left ventricular (LV) and mitral valve (MV) geometry, and their correlation with MR severity. METHODS: Forty-one patients with LBBB and ≥mild secondary MR underwent CRT between 2009 and 2012, and had baseline and follow-up echocardiograms available. Repeated measure and linear regression analyses were performed to assess for changes in MV and LV geometry and MR severity, and associations with follow-up MR grade. RESULTS: The mean age and baseline QRS duration were 65.5 ± 14.9 years and 160 ± 24 ms. At a mean follow-up of 2.6 ± 1.8 years, there was an increase in LV ejection fraction and reductions in LV end-systolic volume index, MR grade, and end-systolic interpapillary muscle distance (P < .05 for all). Linear correlations were observed between follow-up MR grade and baseline MV tenting height (r = .44), left atrial volume index (r = .41), LV end-systolic volume index (r = .4), MV tenting area (r = .38), LV ejection fraction (r = -.34), and end-systolic interpapillary muscle distance (r = .34) (P < .05 for all). Multiple regression analysis revealed associations between follow-up MR grade and baseline MV tenting height (ß/mm = 0.42, P = .006) and left atrial volume index (ß/mL/m2  = 0.4, P = .008), independent of QRS duration (ß/ms=-0.07; P = 0.6) and nonischemic cardiomyopathy (ß = -0.34, P = .02). CONCLUSIONS: Cardiac resynchronization therapy in patients with LBBB and secondary MR results in LV and MV geometric reverse remodeling and decreases MR severity. Extent of baseline MV tethering is independently associated with persistent MR at follow-up.

RESUMO

BACKGROUND: The effects of cardiac resynchronization therapy (CRT) on secondary mitral regurgitation (MR), and mitral valve (MV) and left ventricular (LV) geometry, in patients with prior inferior myocardial infarction is not clearly defined. We assessed these outcomes utilizing two-dimensional echocardiography, and analyzed echocardiographic geometric variables that may correlate with follow-up MR severity. METHODS: Between 2009 and 2012, 229 CRT were implanted. Twenty-two had prior inferior myocardial infarction, ≥mild MR at baseline, and serial echocardiography. A left bundle branch block was present in 12 (54.5%) patients. The pre-CRT and follow-up echocardiograms were analyzed for: (1) MR severity; (2) MV and LV geometry; and (3) LV remodeling. RESULTS: The median follow-up time was 2.2 years (interquartile range, 0.7-4). In 16 patients without an inferior myocardial scar, there was a reduction in MR jet area/left atrial area ratio (33.2% vs 25.8%; P = 0.06) and MR grade (2.3 vs 1.8; P = 0.05), and an increased LV ejection fraction (26.1% vs 30.9%; P = 0.04) and end-systolic posterior ventricular sulcus-anterolateral papillary muscle angle (133.9 vs 143.9 degrees; P = 0.01). In six patients with scar, there was no change in LV or MR parameters. Regression analysis revealed linear associations between baseline MV tenting height (r = 0.57; P = 0.006), LV end-diastolic diameter index (r = 0.5; P = 0.02), mitral septolateral annular diameter (r = 0.48; P = 0.03), and MV tenting area (r = 0.46; P = 0.03), with follow-up MR jet area/left atrial area ratio. CONCLUSIONS: In patients with prior inferior myocardial infarction and no scar, CRT is associated with decreased MR severity, and improved papillary muscle alignment and LV systolic function at follow-up.

RESUMO

BACKGROUND: Left ventricular noncompaction (LVNC) is associated with progressive LV systolic dysfunction and dilated cardiomyopathy. We aimed to investigate the echocardiographic and clinical characteristics associated with LV ejection fraction (LVEF) and moderate or greater systolic dysfunction in patients with LVNC. METHODS: Our institutional echocardiography database was retrospectively reviewed between 2008 and 2014, and 62 patients with LVNC were identified. Forty-three (69%) had moderate or greater LV systolic dysfunction (LVEF ≤ 40%) and were compared with 19 (31%) patients with preserved or mildly reduced LVEF (>40%). Linear regression analyses were utilized to identify markers associated with LVEF. RESULTS: The mean age was 63 ± 17 years and noncompacted-to-compacted ratio was 2.3 ± 0.5, and was larger in patients with LVEF ≤ 40% (2.4 vs 2.1; P = .02). Patients with LVEF ≤ 40% were older, had more congestive heart failure, significant QRS interval prolongation, and greater LV remodeling and worse mean global longitudinal strain (GLS). Multivariate regression analysis revealed increased age (standardized regression coefficient (ß) = -0.17; P = .04) and QRS duration (ß = -0.13; P = .08), congestive heart failure (ß = -0.18; P = .04), and worsened GLS (ß = -0.40; P = .001) were independently associated with decreased LVEF in the cohort (overall model fit R2  = 0.71; P < .0001). Increased age (ß = -0.49; P = .01) and QRS duration (ß = -0.50; P = .002), and worsened GLS (ß = -0.33; P = .04), were also associated with a lower LVEF in patients with LVEF > 40%. CONCLUSIONS: The independent markers associated with LVEF and moderate or greater LV systolic dysfunction in patients with LVNC, in particular GLS and QRS duration, may detect high-risk candidates for more aggressive clinical surveillance and medical therapy.

RESUMO

Amyloidosis is a systemic disorder that results from abnormal protein metabolism, producing amyloid fibrils that are subsequently deposited within vital organs. Cardiac involvement is typically associated with the specific subtypes of immunoglobulin lightchain, transthyretin, secondary amyloidosis, and dialysis-related amyloidosis. The hallmark of cardiac amyloidosis is the development of restrictive cardiomyopathy and heart failure, usually with a preserved left ventricular ejection fraction. The diagnosis is based on the integration of clinical signs and symptoms, echocardiography, cardiac magnetic resonance imaging, nuclear scintigraphy, electrocardiography, and cardiac biomarkers. Traditionally, management of heart failure symptoms and prevention of heart failure exacerbations have been the cornerstones of therapy. However, various treatments are currently under investigation that aim to eliminate or neutralize the underlying amyloidogenic substrate. Herein, we provide a focused review and discussion of the cardiovascular manifestations, epidemiologic and clinical characteristics, diagnostic modalities, and treatment strategies of cardiac amyloidosis.

RESUMO

Uhl's anomaly is a rare cardiac malformation that results in partial or complete absence of the right ventricular myocardium. It most commonly presents in prenatal or newborn infants; however, it may also be found in some adults as advanced right-sided heart failure. Differential diagnoses include arrhythmogenic right ventricular dysplasia and Ebstein's anomaly. Herein, we describe the clinical presentation of Uhl's anomaly in a previously undiagnosed middle-aged adult, and review the echocardiographic criteria used to diagnose and differentiate this rare, albeit important, myocardial disorder.

RESUMO

Pulmonary valve replacement (PVR) is the most common adult congenital cardiac operation performed. Valve degeneration leading to prosthetic stenosis and/or regurgitation is a long-term risk in this population and may be associated with paravalvular leak (PVL). Complications involving the proximal pulmonary artery, including dissection, are less clearly defined. Herein, we report the case of a 30-year-old patient with a history of multiple pulmonary valve interventions secondary to congenital pulmonic stenosis, who developed dehiscence of a bioprosthetic PVR associated with significant paravalvular leak (PVL) and further complicated by a focal dissection of the proximal pulmonary artery.

RESUMO

BACKGROUND: Cardiac resynchronization therapy (CRT) may improve secondary mitral regurgitation (MR) in patients with cardiomyopathy. The effects on mitral valve (MV) and left ventricular (LV) geometry, however, have not been clearly defined. METHODS: Between 2009 and 2012, 229 CRT implants were performed at a single academic center. Seventy-one had ≥mild MR at baseline and serial echocardiography, without subsequent MV intervention. The pre-CRT and follow-up echocardiograms were retrospectively reviewed for (1) MV and LV geometry measurements; (2) MR grade; and (3) LV remodeling indices. RESULTS: The mean age was 67 ± 15 years, and the cardiomyopathy was ischemic in 37 (52%). At a mean follow-up of 4.0 ± 1.9 years, there were significant improvements in LV ejection fraction and size, MR grade, MV tenting area and anterior leaflet tethering angle, and end-systolic interpapillary muscle distance (IPMD), and reductions in moderate-to-severe or severe MR (27% vs 15%; P = .04) and New York Heart Association functional class III/IV symptoms (83% vs 41%; P < .001). Multivariable analysis revealed the pre-CRT MV tenting height (OR 1.25, 95% CI 1.01-1.56; P = .04) and end-systolic IPMD (OR 1.14, 95% CI 0.99-1.32; P = .08) as independently associated with moderate or greater MR at follow-up. Finally, at 5 years post-CRT implantation, the estimated survival and freedom from LV assist device or cardiac transplantation was 61%. CONCLUSIONS: CRT results in favorable effects on MV and LV geometry and decreases the prevalence of moderate-to-severe or severe MR and heart failure symptoms. The pre-CRT MV tenting height and IPMD are independently associated with persistent MR at follow-up.

RESUMO

BACKGROUND: There is a 30-60% incidence of recurrent mitral regurgitation (MR) after mitral valve annuloplasty (Ring) for secondary MR. A concomitant papillary muscle sling (Ring+Sling) may improve valve repair by providing a more physiologic geometry of the mitral apparatus. METHODS: We retrospectively identified 58 consecutive patients with moderate-to-severe secondary MR who underwent a Ring+Sling repair, between March 2008 and May 2015. A Ring+Sling consisted of combined annuloplasty and papillary muscle approximation, utilizing a 4-mm polytetrafluoroethylene graft placed around the base of each muscle. Comparison of echocardiographic variables with patients who underwent a Ring only was performed utilizing 2:1 propensity-score matching (Ring+Sling = 34; Ring = 17). RESULTS: The baseline demographics were similar between the groups. The mean time to follow-up echocardiogram was 10.1 months (range 0.25-42 months). At follow-up, a Ring+Sling repair was associated with a lower mitral valve tenting height (p = 0.005), mitral valve tenting area (p = 0.009), and interpapillary muscle distance (p = 0.001); a smaller posterior leaflet tethering angle (p = 0.003); and a greater leaflet coaptation length (p = 0.002), when compared with Ring only. Recurrence of moderate or greater MR occurred significantly less in the Ring+Sling group (14.7%), as compared with Ring only (35.3%) (p < 0.001). Finally, actuarial survival at three years was 87% for Ring+Sling, and 82% for Ring only (p = 0.49). CONCLUSIONS: A Ring+Sling for secondary MR results in favorable changes in the mitral valve apparatus geometry, and is associated with less MR recurrence in the early postoperative period. Longer-term follow-up is needed to assess its durability and effects on left ventricular remodeling and survival.

RESUMO

Mitral annular calcification (MAC)-related mitral valve (MV) dysfunction is an increasingly recognized entity, which confers a high burden of morbidity and mortality. Although more common among women, there is a paucity of data regarding how the phenotype of MAC and the associated adverse clinical implications may differ between women and men. A total of 3,524 patients with extensive MAC and significant MAC-related MV dysfunction (i.e., transmitral gradient ≥3 mm Hg) were retrospectively analyzed from a large institutional database, with the goal of defining gender differences in clinical and echocardiographic characteristics and the prognostic importance of MAC-related MV dysfunction. We stratified patients into low- (3 to 5 mm Hg), moderate- (5 to 10 mm Hg), and high- (≥10 mm Hg) gradient groups and analyzed the gender differences in phenotype and outcome. The primary outcome was all-cause mortality, assessed using adjusted Cox regression models. Women represented the majority (67%) of subjects, were older (79.3 ± 10.4 vs 75.5 ± 10.9 years, p <0.001) and had a lower burden of cardiovascular co-morbidities than men. Women had higher transmitral gradients (5.7 ± 2.7 vs 5.3 ± 2.6 mm Hg, p <0.001), more concentric hypertrophy (49% vs 33%), and more mitral regurgitation. The median survival was 3.4 years (95% confidence interval 3.0 to 3.6) among women and 3.0 years (95% confidence interval 2.6 to 4.5) among men. The adjusted survival was worse among men, and the prognostic impact of the transmitral gradient did not differ overall by gender. In conclusion, we describe important gender differences among patients with MAC-related MV dysfunction and show worse adjusted survival among men; although, the adverse prognostic impact of the transmitral gradient was similar between men and women.

RESUMO

Mitral annular calcification (MAC) is a common clinical finding and is associated with adverse clinical outcomes, but the clinical impact of MAC-related mitral valve (MV) dysfunction remains underappreciated. Patients with MAC frequently have stenotic, regurgitant, or mixed valvular disease, and this valvular dysfunction is increasingly recognized to be independently associated with worse prognosis. MAC-related MV dysfunction is a distinct pathophysiologic entity, and importantly much of the diagnostic and therapeutic paradigm from published rheumatic MV disease research cannot be applied in this context, leaving important gaps in our knowledge. This review summarizes the current epidemiology, pathophysiology, diagnosis, and classification of MAC-related MV dysfunction and proposes both an integrative definition and an overarching approach to this important and increasingly recognized clinical condition.

RESUMO

The incidence of injection drug use-associated infective endocarditis has been increasing rapidly over the last decade. Patients with drug use-associated infective endocarditis present an increasingly common clinical challenge with poor long-term outcomes and high reinfection and readmission rates. Their care raises issues unique to this population, including antibiotic selection and administration, indications for and ethical issues surrounding surgical intervention, and importantly management of the underlying substance use disorder to minimize the risk of reinfection. Successful treatment of these patients requires a broad understanding of these concerns. A multidisciplinary, collaborative approach providing a holistic approach to treating both the acute infection along with effectively addressing substance use disorder is needed to improve short-term and longer-term outcomes.

RESUMO

The prevalence of mitral annular calcium (MAC) is increasing in our aging population. However, data regarding prognostication in MAC-related mitral valve (MV) disease remain limited. This retrospective observational study aims to explore the prognostic impact of systolic pulmonary artery pressure (SPAP) in MAC-related MV dysfunction and define its determinants. We identified 4,384 patients (mean age 78 ± 11 years and 69% female) with MAC-related MV dysfunction (documented transmitral gradient ≥3 mm Hg) from a large institutional echocardiographic database between 2001 and 2019. In Cox regression analysis, higher SPAP strongly associated with all-cause mortality, independent of cardiovascular risk factors and indices of MV dysfunction (adjusted hazard ratio 1.22 per 10 mm Hg SPAP increase, 95% confidence interval 1.17 to 1.27). Patients with SPAP ≥50 mm Hg had significantly higher mortality compared with SPAP <50 mm Hg (log-rank p <0.001), a finding that was consistent across different transmitral gradient subgroups (≤5, 5 to 10, and ≥10 mm Hg). Independent determinants of SPAP included the mean transmitral gradient, mitral regurgitation severity, left ventricular ejection fraction, and ≥moderate aortic stenosis (adjusted p <0.05), and atrial fibrillation and left atrial dimension. The impact of concomitant mitral regurgitation on SPAP decreased at higher transmitral gradients and was no longer significant at gradients ≥10 mm Hg (p = 0.100). In conclusion, SPAP strongly associates with mortality in MAC, independent of cardiovascular risk factors and indices of MAC-related MV dysfunction. These findings suggest an incremental role for SPAP in the risk stratification and prognostication in this increasingly prevalent condition with expanding the scope of possible interventions.

RESUMO

AIMS: Prediction of mitral (MR) and tricuspid (TR) regurgitation progression on transthoracic echocardiography (TTE) is needed to personalize valvular surveillance intervals and prognostication. METHODS AND RESULTS: Structured TTE report data at Beth Israel Deaconess Medical Center, 26 January 2000-31 December 2017, were used to determine time to progression (≥1+ increase in severity). TTE predictors of progression were used to create a progression score, externally validated at Massachusetts General Hospital, 1 January 2002-31 December 2019. In the derivation sample (MR, N = 34 933; TR, N = 27 526), only 5379 (15.4%) individuals with MR and 3630 (13.2%) with TR had progression during a median interquartile range) 9.0 (4.1-13.4) years of follow-up. Despite wide inter-individual variability in progression rates, a score based solely on demographics and TTE variables identified individuals with a five- to six-fold higher rate of MR/TR progression over 10 years (high- vs. low-score tertile, rate of progression; MR 20.1% vs. 3.3%; TR 21.2% vs. 4.4%). Compared to those in the lowest score tertile, those in the highest tertile of progression had a four-fold increased risk of mortality. On external validation, the score demonstrated similar performance to other algorithms commonly in use. CONCLUSION: Four-fifths of individuals had no progression of MR or TR over two decades. Despite wide interindividual variability in progression rates, a score, based solely on TTE parameters, identified individuals with a five- to six-fold higher rate of MR/TR progression. Compared to the lowest tertile, individuals in the highest score tertile had a four-fold increased risk of mortality. Prediction of long-term MR/TR progression is not only feasible but prognostically important.

RESUMO

Background Many patients with severe aortic stenosis (AS) and an indication for aortic valve replacement (AVR) do not undergo treatment. The reasons for this have not been well studied in the transcatheter AVR era. We sought to determine how patient- and process-specific factors affected AVR use in patients with severe AS. Methods and Results We identified ambulatory patients from 2016 to 2018 demonstrating severe AS, defined by aortic valve area [Formula: see text]1.0 cm2. Propensity scoring analysis with inverse probability of treatment weighting was used to evaluate associations between predictors and the odds of undergoing AVR at 365 days and subsequent mortality at 730 days. Of 324 patients with an indication for AVR (79.3±9.7 years, 57.4% men), 140 patients (43.2%) did not undergo AVR. The odds of AVR were reduced in patients aged >90 years (odds ratio [OR], 0.24 [95% CI, 0.08-0.69]; P=0.01), greater comorbid conditions (OR, 0.88 per 1-point increase in Combined Comorbidity Index [95% CI, 0.79-0.97]; P=0.01), low-flow, low-gradient AS with preserved left ventricular ejection fraction (OR, 0.11 [95% CI, 0.06-0.21]), and low-gradient AS with reduced left ventricular ejection fraction (OR, 0.18 [95% CI, 0.08-0.40]) and were increased if the transthoracic echocardiogram ordering provider was a cardiologist (OR, 2.46 [95% CI, 1.38-4.38]). Patients who underwent AVR gained an average of 85.8 days of life (95% CI, 40.9-130.6) at 730 days. Conclusions The proportion of ambulatory patients with severe AS and an indication for AVR who do not receive AVR remains significant. Efforts are needed to maximize the recognition of severe AS, especially low-gradient subtypes, and to encourage patient referral to multidisciplinary heart valve teams.

RESUMO

The anorexia-cachexia syndrome (ACS) occurs in many chronic illnesses, such as cancer, AIDS, and chronic obstructive pulmonary disease in addition to chronic congestive heart failure (CHF). Comparable to other chronic states, the ACS complicates CHF and impacts its prognosis; however, the available treatment options for this syndrome remain unsatisfactory. This review article focuses on the complex pathophysiology of cardiac anorexia. We focus on the recent data demonstrating the relationships between central appetite-regulating structures, inflammatory processes, and neurohormonal activation, and their respective roles in the development of anorexia. We then describe the different treatment options and discuss some future prospects for the management for cardiac anorexia.
