Abstract

The authors report 5 cases of annular subvalvular left ventricular idiopathic aneurysm observed within less than 4 years (April 1984 to October 1987) at the hospital of Niamey, Niger. All 5 patients were examined by echocardiography, an exploratory technique which is new for this type of disease. The condition is rare and has been described mostly in black people living in African countries. At the hospital of Niamey, annular subvalvular left ventricular aneurysm was found in 0.04 p. 100 of in-patients and accounted for 0.34 p. 100 of all cardiovascular diseases. The patients were young adults (mean age 20 years), and at the time of diagnosis all were in stage III or IV heart failure. An apical systolic murmur was regularly present; it was due to the mitral regurgitation resulting from the traction exerted by the aneurysm. The prognosis was unfavourable. There were 3 deaths, 2 of which were directly ascribable to the aneurysm and due to thromboembolism (1 case) and arrhythmia (1 case) which are recognized complications of that disease. The diagnosis, always suspected on the finding, on frontal radiographs, of a protruding left cardiac border, was hitherto confirmed by angiography; the authors did not perform angiography and con...Continue Reading

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.

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.

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.

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.
