Abstract

A 52 year old patient with no previous medical history had an attack of ventricular tachycardia, the configuration of which showed left sided delay. Electrical reduction was followed by multiple recurrences. There were ST-T wave changes over the right precordium on the basal ECG. The hydro-electrolytic equilibrium was normal. Coronary angiography and selective left ventricular cineangiography were also normal. Right angiocardiography showed an aneurysmal deformation of the pulmonary infundibulum. The recurrence of attacks over a two year period led to several hospital admissions, demonstrating the failure of antiarrhytmic therapy. The attacks became so frequent in the last three months that surgery was undertaken. Epicardial mapping showed delayed potentials over the pulmonary infundibulum and surgery consisted in resection of the abnormal infundibular zone. The macro- and microscopic pathological findings were of wall thinning and muscular degeneration with fibrosis and fatty infiltration. The authors discuss the relationship between right ventricular dysplasia and a localised form of Uhl's anomaly. Six years after surgery the patient has had no recurrence of the arrhythmia or shown signs of cardiac failure in the absence of a...Continue Reading

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.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Aneurysm

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

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias. Discover the latest research on arrhythmogenic right ventricular dysplasia 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.
