A transthoracic, left ventricular vent facilitates challenging sternal reentry.

Abstract

In this brief report, we describe a technique to facilitate hypothermic arrest before a redo sternotomy that is likely to require extensive dissection. This approach may be well-suited for patients with significant aortic insufficiency, as it allows control of left ventricular distention once hypothermic ventricular fibrillation ensues. The procedure entails inserting a second venous cannula through the left ventricular apex through a 7-cm left mini-thoracotomy. We used the technique successfully in a patient with a ruptured, infected ascending aortic pseudoaneurysm and severe aortic insufficiency who had undergone a previous sternotomy.
