ObjectiveTo assess outcomes of transcatheter aortic valve replacement (TAVR) for pure native aortic valve regurgitation.MethodsA total of 129 patients underwent transfemoral TAVR in Fuwai Hospital from May 2019 to October 2020 were retrospectively analyzed. There were 83 males and 46 females with an average age of 72.26±8.97 years. The patients were divided into a pure native aortic valve regurgitation group (17 patients) and an aortic valve stenosis group (112 patients).ResultsThe incidence of valve in valve was higher in the pure native aortic valve regurgitation group (47.0% vs. 16.1%, P<0.01). There was no statistical difference between the two groups in conversion to surgery, intraoperative use of extracorporeal circulation, intraoperative left ventricular rupture, postoperative use of extracorporeal membrane oxygenation (ECMO), peripheral vascular complications, disabled stroke, death, or pacemaker implantation. There was no statistical difference in the diameter of annulus (25.75±2.21 mm vs. 24.70±2.90 mm, P=0.068) or diameter of outflow tract (25.82±3.75 mm vs. 25.37±3.92 mm, P=0.514) between the pure native aortic valve regurgitation group and the aortic valve stenosis group.ConclusionTransfemoral TAVR is a feasible method for patients with pure native aortic valve regurgitation. The diameter of annulus plane, the diameter of outflow tract and the shape of outflow tract should be evaluated.
