Retrospective Analysis of the Experience in Diagnostics and Surgical Treatment of Rare Cardiac Tumors-Lipomas

The aim of this study is to determine the optimal treatment tactics for cardiac lipomas by performing a retrospective analysis of the features of the clinical course, diagnostics and specifics of surgery for this pathology. At Amosov NICVS, in the period from 1969 to 01.01.2020, 968 patients with various types of cardiac tumors underwent surgical treatment, of which 36 patients were with non-myxomas benign tumors. Cardiac lipoma diagnosed in three cases (0.3%). The described cases demonstrate a significant risk of heart damage by benign neoplasms (lipoma), the operability of neoplasm is largely determined by the localization and volume of myocardial involvement. In the two cases described, a lipoma due to the localization in the left ventricle and right ventricle walls and transmyocardial penetration of the neoplasm led the risk of rupture of the penetrated walls of the ventricles and to almost incurable arrythmias. Surgical tactics for these neoplasms should be based on the size of the tumor, its location and the presence of obvious hemodynamic disturbances due to the obstructive form of the neoplasm.
