Simultaneous pressure recording in mid-ventricular obstructive hypertrophic cardiomyopathy

Internal Medicine

Abstract

A 70-year-old man was diagnosed with mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHCM) with apical aneurysm and paradoxic jet flow. At cardiac catheterization, pressure study showed that there was a markedly high pressure-gradient of 90 mmHg between the apex and the base in systole. Apical pressure was 350 mmHg after premature ventricular contraction. The apical aneurysm was already dilated and spherical in late systole; the absence of active relaxation was considered to be the cause of the paradoxic jet flow. In this report, we suggest the pathogenesis of left ventricular apical aneurysm and paradoxic jet flow in MVOHCM.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

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.
