Kinking of the pulmonary artery: a treatable cause of acute right ventricular failure after heart transplantation.

Abstract

Kinking of the pulmonary artery has been reported only once as a cause of acute right ventricular failure after heart transplantation. We report two cases of kinking of the pulmonary artery encountered during a 3-year period (120 heart transplants). An analysis of the causes of this complication and a diagnostic and therapeutic approach are presented.
