Abstract

This study uses pulsed Doppler tissue imaging to analyse right ventricular myocardial function and its interaction with left ventricle in hypertrophic cardiomyopathy involving ventricular septum. Thirty-four patients with septal hypertrophic cardiomyopathy and 30 normal subjects, comparable for sex, age, body mass index and heart rate, underwent complete standard Doppler echocardiography and pulsed Doppler tissue imaging of both posterior septum and right ventricular free wall, calculating myocardial velocities and both systolic and diastolic time intervals. Except for peak velocity A, the other Doppler tricuspid inflow measurements were significantly impaired in hypertrophic cardiomyopathy, without changes of tricuspid annular systolic excursion. Right ventricular Doppler tissue imaging showed longer right ventricular myocardial relaxation time in hypertrophic cardiomyopathy than in controls (P<0.00001), without a significant difference from other myocardial diastolic and systolic measurements. In the overall population, Doppler measurements of right and left ventricular inflow were not significantly associated, while (with the exception of myocardial deceleration time) all the other myocardial systolic and diastolic measureme...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
