Aims: Concomitant severe calcific aortic and mitral stenosis is a relatively uncommon but very challenging valvular heart disease to manage. We sought to evaluate the feasibility of a fully percutaneous approach to replace both stenotic native mitral and aortic valves using SAPIEN 3 valves.
Methods and results: An 87-year-old woman with chronic kidney disease stage 3, pul-monary hypertension, chronic obstructive pulmonary disease, a permanent pacemaker, and atrial fibrillation was referred with Class III heart failure symptoms. Her echocardiogram showed a decreased ejection fraction at 45%, severe mitral stenosis (mean gradient 13 mmHg, area 0.8 cm2) with severe MAC, and severe AS (mean gradient 35 mmHg, area 0.6 cm2). Surgical risk was felt to be very high after evaluation by our cardiothoracic sur-gery group (Society of Thoracic Surgeons risk score of 19%). She underwent simultaneous and fully percutaneous trans-femoral TAVR and transseptal TMVR using SAPIEN 3 valves. Post-implant TEE showed trace paravalvular mitral regurgitation and a mean gradient of 4 mmHg and mean aortic gradient of 8 mmHg with trace paravalvular leak. There was no LVOT obstruction. The patient was discharged seven days after the intervention.
Conclusions: After careful evaluation by experienced Heart Teams, combined native stenotic mitral and aortic valves can be percutaneously replaced using transcatheter SAPIEN 3 valves via transfemoral access in carefully selected high surgical risk patients.
