T-Wave Microalternans in Hypertrophic Cardiomyopathy: The Complexity of an Inherited Cardiac Condition with Multiple Phenotypic Expressions

The fact that ventricular tachyarrhythmia is the most frequent cause of sudden cardiac death (SCD) in cardiomyopathies (CM) does not mean that all CM exhibit similar structural and functional alterations that, identified in advance, for example, by analyzing changes in ventricular depolarization and repolarization, may collaborate in the primary prevention of SCD.

In the current edition of ABC Cardiol, Antunes et al. reveals that altered T-wave alternans (TWA) is not associated with SCD and/or malignant ventricular arrhythmias in hypertrophic cardiomyopathy (HCM) patients. This suggests that diagnostic methods used for non-ischemic cardiomyopathies (NICM). stratification may not universally apply across a heterogeneous set of pathologies.

Cardiac Magnetic Resonance and Computed Tomography in Hypertrophic Cardiomyopathy: an Update

Diogo Costa Leandro de Oliveira et al. Fernanda Boldrini Assunção Alair Agusto Sarmet Moreira Damas dos Santos Marcelo Souto Nacif

Abstract

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease and represents the main cause of sudden death in young patients. Cardiac magnetic resonance (CMR) and cardiac computed tomography (CCT) are noninvasive imaging methods with high sensitivity and specificity, useful for the establishment of diagnosis and prognosis of HCM, and for the screening of patients with subclinical phenotypes. The improvement of image analysis by CMR and CCT offers the potential to promote interventions aiming at stopping the natural course of the disease. This study aims to describe the role of RCM and CCT in the diagnosis and prognosis of HCM, and how these methods can be used in the management of these patients.
