OBJECTIVES The objective of the study was to determine whether the extent of left ventricular scar, measured with delayed hyperenhancement cardiac magnetic resonance (DHE-CMR), predicts survival in patients with ischemic cardiomyopathy (ICM) and severely reduced left ventricular ejection fraction (LVEF). BACKGROUND Patients with ICM and reduced LVEF have(More)
OBJECTIVE Many high-risk patients with severe symptomatic aortic stenosis are not referred for surgical aortic valve replacement. Although this patient population remains ill-defined, many of these patients are now being referred for percutaneous aortic valve replacement. We sought to define the characteristics and outcomes of patients referred for(More)
High fidelity genome-wide expression analysis has strengthened the idea that microRNA (miRNA) signatures in peripheral blood mononuclear cells (PBMCs) can be potentially used to predict the pathology when anatomical samples are inaccessible like the heart. PBMCs from 48 non-failing controls and 44 patients with relatively stable chronic heart failure(More)
OBJECTIVES Our purpose was to investigate a new approach to bicommissural repair of regurgitant aortic valves. BACKGROUND Repair of regurgitant aortic valves is not widely accepted, but interest is increasing, particularly for bicuspid valves. We hypothesize that a systematic, segmental approach to morphology and corresponding morphology-directed repair(More)
BACKGROUND Obesity is a major public health epidemic and is associated with increased risk of heart failure and mortality. We evaluated the impact of body mass index (BMI) on the prevalence of diastolic dysfunction (DD). METHODS We reviewed clinical records and echocardiogram of patients with baseline echocardiogram between 1996 and 2005 that showed(More)
BACKGROUND Diastolic dysfunction (DD) is known to be associated with increased mortality rate in the presence of impaired systolic function. However, few prognostic data exist regarding the effect of DD in patients with normal systolic function. METHODS We reviewed clinical records and echocardiographic findings of consecutive patients who underwent an(More)
BACKGROUND Diastolic dysfunction is an independent predictor of mortality in patients with normal left ventricular ejection fraction. There are limited data, however, on whether worsening of diastolic function is associated with worse prognosis. METHODS AND RESULTS We reviewed clinical records and echocardiograms of consecutive patients who had baseline(More)
OBJECTIVES We sought to assess outcomes of alcohol septal ablation (ASA) in high-risk patients. BACKGROUND Because surgical myectomy is the preferred treatment in patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) at our institution, we perform ASA in patients who are at high risk for surgery. METHODS We studied 55 symptomatic HOCM(More)
AIMS We sought to determine the association between myocardial scarring, gender, and survival in patients with significant coronary artery disease (CAD) and severe systolic left ventricular (LV) dysfunction using delayed hyper-enhancement cardiac magnetic resonance imaging (DHE-CMR). METHODS AND RESULTS We studied 339 patients (24% women, mean age 65 +/-(More)
We sought to assess the prognostic value of diastolic dysfunction (DD) in low-risk adults beyond Framingham risk score (FRS). Consecutive patients without cardiovascular risk factors or co-morbidities were identified from a retrospective cohort. Multivariate binary logistic regression was performed to identify factors associated with DD, and Cox(More)
