Aneurimas of the heart

Aneurimas of the heart . Myocardial infarction in 10-15% of cases is complicated by the development of an aneurysm. Most postinfarction aneurysms are located on the anterior wall of the left ventricle near the apex of the heart. Less often the cause of aneurysms is trauma, rheumatism.

Symptoms, course. Small aneurysms (less than 4 cm) can be asymptomatic. As a rule, there are violations of myocardial function, due to the underlying disease. An increase in the heart boundaries, precordial pulsation, an ECG-characteristic frozen monophasic curve, typical for myocardial infarction, is determined. Radiographic examination reveals vybuhaniya heart contour. The size and exact localization of an aneurysm is established with the help of roentgenogram. It is necessary to carefully study the function of the myocardium - catheterization of the heart cavities with the study of diastolic pressure, etc. Indication for surgery is the risk of aneurysm rupture, increasing left ventricular failure, thromboembolic complications, recurrent ventricular tachycardia.

The operation consists, as a rule, in subtotal excision of the aneurysmal sac. Postoperative lethality is 5-15%.
