Abstract

The intraventricular resection technique for giant aneurysm of the left ventricle decreases anoxic cardiac arrest time and controls the detachment of intramural thrombus. To perform this technique, it is necessary to expose only a longitudinal segment on the anterior aspect of the aneurysm to permit a ventriculotomy parallel to the anterior descending coronary artery 4-5 cm away. In the same way, to resect a giant aneurysm of the diaphragmatic aspect, only a segment parallel to the posterior descending coronary artery needs to be exposed. Then with the clear intraventricular vision of the limit between the fibrous sac and the contracting left ventricle, the surgeon rapidly detaches the aneurysm. In any case besides the relation of this limit, the transecting line must keep away at least 4 cm from the implantation of the papillary muscle of the mitral valve, in order to leave an adequate functional chamber for the left ventricle. The early visualization of the mitral apparatus during the resection of giant aneurysm is another basic advantage of the intraventricular approach. The ventriculotomy is closed with a running suture and coronary circulation is restored. Anoxic cardiac arrest averaged 15 minutes in the five out of six ca...Continue Reading

Aneurysm

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

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

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.
