Chylothorax: a complication after internal thoracic artery harvesting.

Chylothorax is a rare but serious complication of cardiac surgery. A 64-year-old man with three-vessel disease underwent coronary artery bypass grafting. Ten days later he developed left pleural effusion. An intercostal drain was inserted and 1600 ml of pale pink, milky fluid were obtained. The results of biochemical analysis were consistent with chyle. The diagnosis of a left chylothorax was made. Conservative treatment consisting of total parenteral nutrition and pleural drainage was successfully employed. In the literature we found 17 cases in which the development of chylothorax after a coronary revascularization procedure is described.

A novel technique for giant left atrium reduction.

We herein describe a safe and reproducible technique for left atrial volume reduction in patients with a giant left atrium. In a 56-year-old patient undergoing redo mitral valve replacement, the left atrium measured 18 x 20 x 17 cm occupying the middle-lower segment of the right hemithorax with compression of the adjacent organs. The left atrial volume was reduced by triangular resections of the atrial wall and the mitral valve was replaced using a mechanical prosthesis. The postoperative course was uneventful and the left atrial diameter was 11.2 cm at the latest control.
