Abstract
The primary heart tumors have an incidence varying from 0.001% to 0.28% of all tumors, reported in necropsies series. Lipoma consists of a benign tumour corresponding to about 8% of all primary heart tumors. When present, the symptoms are related to the size and location of such tumor. We report a case of a 27-year-old man with a lipoma in the right atrium who underwent surgical treatment with tumor resection and partial reconstruction of the right atrium using bovine pericardium.
Highlights
Cardiac lipomas are rare with incidence of 8.4% among all primary tumors [1]
Lipoma is composed of fat cells, originated from the epimyocardium and can attach both to the fibrous tissue, as the muscle tissue [1]
There is a primary tumor of the heart for every 5,000 non-selected autopsies
Summary
Cardiac lipomas are rare with incidence of 8.4% among all primary tumors [1]. In turn, the secondary tumors are 30 to 40 times more frequent than the primary ones [2].Lipoma is composed of fat cells, originated from the epimyocardium and can attach both to the fibrous tissue (pericardium), as the muscle tissue (subepicardial) [1].The clinical changes are generally mechanical and result of the location of the tumor, and this may cause valve dysfunction or heart compression, compromising the cardiac dynamic.The therapy indicated for the treatment of primary tumors of the heart is the total resection of the tumor in order to avoid primary and secondary complications, which are the obstruction and embolization [3].The first report of success in resection of epicardial lipoma occurred in 1954 by Maurer et al [4]. Cardiac lipomas are rare with incidence of 8.4% among all primary tumors [1]. Lipoma is composed of fat cells, originated from the epimyocardium and can attach both to the fibrous tissue (pericardium), as the muscle tissue (subepicardial) [1].
