Structural abnormalities in hypertrophic cardiomyopathy beyond left ventricular hypertrophy by multimodality imaging evaluation.

Background: Echocardiography- and cardiovascular magnetic resonance (CMR)-based studies have revealed a wide range of phenotypic manifestations in hypertrophic cardiomyopathy (HCM) apart from hypertrophy. This study sought to comprehensively describe a number of structural abnormalities in HCM beyond hypertrophy, by multimodality imaging.

Methods: A total of 100 HCM patients were prospectively enrolled, undergoing standard and contrast echocardiography, and CMR.

Clinical and echocardiographic course in tako-tsubo cardiomyopathy: Long-term follow-up from a multicenter study.

Objectives: To jointly describe clinical characteristics, ECG and echocardiographic findings, and adverse cardiovascular events in patients with tako-tsubo cardiomyopathy (TC) in the long-term.

Methods: Longitudinal multicenter study including retrospective analysis of clinical and ECG data, and follow-up evaluation with clinical interview, electrocardiogram and echocardiogram.

Results: Data from 66 cases of TC were available for analysis of clinical and adverse cardiovascular events, and 56 of them completed the follow-up visit including electrocardiogram and echocardiogram.
