Abstract

Objective: Aortic valve replacement is the standard of care for severe, symptomatic aortic valve stenosis (AS); however, anatomy or preexisting comorbidities may preclude conventional or alternative transcatheter approaches. Aortic valve bypass (AVB)may be performed as a salvage procedure for the relief of symptomatic aortic stenosis in patients who are not suitable candidates for aortic valve replacement. Methods: At our institution, seven patients underwent AVB using the Correx automated coring and apical connector system. All patients had severe AS with New York Heart Association functional class 3 symptoms and were not candidates for conventional or transcatheter approaches. Via a left anterolateral thoracotomy to access the descending aorta and left ventricular apex, we used the Correx system (Correx, Waltham, MA USA) to anastomose a valve conduit to the left ventricular apex proximally and the descending aorta distally. Three patients required cardiopulmonary bypass. Results: In all seven patients, the automated coring and apical connector was successfully deployed. Therewere two in-hospital deaths in this series. Immediately postoperatively and at 3 months, there was a significant reduction in mean and peak valve gradients, and all surviving patients performed at New York Heart Association functional class 1. Conclusions: Aortic valve bypass seems to be an acceptable alternative for the treatment of severe AS in high-risk patients who are not candidates for aortic valve replacement. The Correx automated system may improve the clinical applicability and surgical reproducibility of AVB in appropriately selected patients in which conventional or transcatheter aortic valve replacement is not a feasible options.
