Hypertrophic cardiomyopathy is a complex genetic cardiovascular disorder with substantial variability in phenotypic expression and natural progression. Recent research demonstrates the incremental utility of cardiac magnetic resonance in the diagnosis, therapeutic planning, and prognostication of this disease. The increasing incorporation of multimodality(More)
BACKGROUND Takotsubo cardiomyopathy (TC) mimics acute myocardial infarction (AMI). We postulated that ventricular dysfunction in TC in the absence of significant myocardial necrosis would produce higher B-type natriuretic peptide (BNP)/troponin T (TnT) and BNP/creatine kinase MB fraction (CKMB) ratios than in AMI. METHODS AND RESULTS We studied 58(More)
BACKGROUND In patients with hypertrophic cardiomyopathy and left ventricular outflow tract (LVOT) obstruction, but without basal septal hypertrophy, we sought to identify mitral valve (MV) and papillary muscle (PM) abnormalities that predisposed to LVOT obstruction, using echo and cardiac magnetic resonance. METHODS AND RESULTS We studied 121 patients(More)
BACKGROUND Hypertrophic cardiomyopathy (HCM) is a primary myopathic process in which regional left ventricular dysfunction may exist without overt global left ventricular dysfunction. In obstructive HCM patients who underwent surgical myectomy (SM), we sought to determine if there is a significant association between echocardiographic longitudinal strain,(More)
Patients with obstructive hypertrophic cardiomyopathy (HC) have various left ventricular (LV) shapes: reverse septal curvature (RSC, commonly familial), sigmoid septum (SS, common in hypertensives), and concentric hypertrophy (CH). Longitudinal (systolic and early diastolic) strain rate (SR) is sensitive in detecting regional myocardial dysfunction. We(More)
OBJECTIVE Due to their unique pathophysiological profile, patients with hypertrophic cardiomyopathy (HCM) undergoing non-cardiac surgery require additional attention to perioperative management. We sought to compare perioperative outcomes of patients with HCM undergoing non-cardiac surgery with a matched group patients without HCM. METHODS This(More)
