Background
There are limited clinical records in the literature regarding aortic valve replacement in left ventricular assist device (L-VAD) patients. Previously we had two cases of severe aortic valve regurgitation in patients with L-VAD support treated with Corvalve prosthesis insertion and Amplatzer closure procedure. Both patients died a few days after the procedure from complications not related to the procedure itself.Patient History
The patient was a male with previous coronary artery bypass graft surgery in 2001 that was complicated with postischemic dilated cardiomyopathy with severe heart failure (ejection fraction [EF], 20%). Cardiac resynchronization therapy was biventricular-pacemaker and cardiac defibrillator implantation in 2009 for recurrent ventricular arrhythmia. L-VAD implantation (Jarvik 2000) with graft apposition in descending thoracic aorta through left thoracotomy access and retro-auricolar cable was performed in October 2013. In 2015 the patient underwent surgical aortic valve replacement with bioprothesis due to progressive worsening of the aortic valve regurgitation. The Jarvik 2000 outflow was occluded with vascular ball occluder inserted via right axillary artery under fluoroscopy before CEC installation. The recovery was without major complications.Discussion
Long-time survivors with Jarvik 2000 are increasing in number and such late complication is expected to become a main future issue. Our previous experience with the interventional approach was delusive. Due to the fatal consequences in similar patients with nonsurgical approaches, we opted for surgical aortic valve replacement. At the moment, the international literature does not describe safe approaches regarding aortic valve replacement in patients with Jarvik 2000 L-VAD. This case shows that surgical valve replacement could be managed with success according to the described specific technique. 相似文献6.
