ABSTRACT
Arterial switch operation for transposition of great arteries (TGA) is the choice of surgical treatment for this condition. Conventional "open" coronary transfer technique has been commonly employed with good results in experienced hands. A modified "closed" technique of coronary transfer, with a more accurate coronary artery placement taking into account a distended aorta, along with anterior interrupted sutures to reduce purse stringing and other advantages is described.
ABSTRACT
Calcified amorphous tumors (CATs) of the heart are rare, nonneoplastic, intracavitary lesions, previously thought of as pseudotumors, hamartomas, or calcified thrombi, only reported in few adults in the available literature. This report describes a case of a pedunculated oscillating CAT arising from the left atrial appendage that prolapses through the mitral valve and causes severe mitral regurgitation in a newborn. This is the only case of cardiac CAT described in a neonate.
