Minimally Invasive Transaortic Mitral Decalcification During Aortic Valve Replacement.

Mitral annular calcification accompanied by aortic stenosis is hazardous for both double-valve replacement and transcatheter aortic valve implantation. Less invasive mitral procedure is required in this condition, and minimally invasive approach may further reduce the operative risk in high-risk patients. Here, we report minimally invasive transaortic mitral decalcification during aortic valve replacement through minithoracotomy. We believe that this option is feasible in patients who are at prohibitive risk for double-valve replacement or transcatheter aortic valve implantation because of severe mitral annular calcification.
