Two cases of transthoracic pericardial fenestration for pericardial effusion.

Abstract

Pericardial effusion and cardiac tamponade are often refractory and difficult to manage. The transthoracic pericardial fenestration which create a window is the conventional procedure for releasing pericardial effusion to the thoracic cavity. We experienced two cases of pericardial fenestration. The first case was a patient with hypertrophic cardiomyopathy with pericardial effusion. She had a thoracic compression fracture, which indicated pericardial fenestration before an orthopedic surgery. The second case was a patient with recurrent cardiac tamponade caused by postpericardiotomy syndrome after off-pump coronary artery bypass grafting. In both cases, the patients underwent left anterior thoracotomy of about 10 cm at the level of the 5th intercostal space. The pericardium was incised within a radius of about 20 mm; furthermore, the fenestrated window was opened to the left thoracic cavity. In this paper, we present our experience of pericardial fenestration and discuss a review of the literature.
