Transcatheter aortic valve replacement (TAVI), though a preferred treatment option in the elderly population carrying increased risks for open heart surgery, may result in prognosis-limiting moderate or severe aortic regurgitation. Here, we report a series of 11 patients from 3 German TAVI centers, suffering from moderate- to high-grade aortic regurgitation after CoreValve implantation, who were subsequently treated by Edwards Sapien XT implantation.
Methods: The patients were 79.5 ± 4.2 years of age and presented between November 2009 and February 2013 with a symptomatic high-grade aortic stenosis (mean maximum gradient 57 ± 22 mmHg) and EuroSCORE of 16 ± 7%. Initial implantation of a Medtronic CoreValve resulted in moderate-to-severe aortic regurgitation (grade 2.64 ± 0.37) although postdilatation was attempted in eight cases and snare repositioning was attempted in one case.
Results: All 11 patients were treated by a Sapien XT (Edwards) valve implanted into the initially deployed CoreValve: four via transfemoral, one via transaortical and six via transapical approaches. Successful implantation was possible in all 11 patients resulting in a reduction of aortic regurgitation to mean grade 0.23 ± 0.39. Two patients required permanent pacemaker. After 30 days, ten patients were alive, whereas one patient succumbed to pneumonia complicating advanced chronic obstructive pulmonary disease.
Conclusion: In the instance of moderate or severe aortic regurgitation after TAVI of a CoreValve, transfemoral or transapical Sapien XT valve-in-valve deployment is an excellent option to reduce residual regurgitation to none or mild.
