Abstract:
A 47 year-old man with frequent attacks of ventricular tachycardia (VT) due to arrhythmogenic right ventricular dysplasia (ARVD) developed severe right heart failure following cryoablation of the multiple VT focuses. Inotropic support and intraaortic balloon pumping failed to maintain the systemic circulation, so that we performed the right heart bypass (RHB) using a heparin-coated tube and roller pump. With the use of RHB, systemic circulation improved. We attempted to wean the patient off after 14 days RHB support. However this was unsuccessful because of poor RV function, and RHB was recommenced. The patient finally died of multiple organ failure on the 21st postoperative day, but the major organ function was well maintained for at least two weeks. The heparin-coated tube and roller pump system is easy to handle, and is suitable as a short term lifesaving adjunct for severe right ventricular failure.
