Safety and Efficacy of Simultaneous Biplane Mode of 3-Dimensional Transesophageal Echocardiography-Guided Antegrade Multiple-Inflation Balloon Aortic Valvuloplasty in Patients With Severe Aortic Stenosis

摘要

Background: Balloon aortic valvuloplasty (BAV) is resurging as a bridge treatment in patients with severe aortic stenosis (AS) with a dissemination of transcatheter aortic valve implantation. However, the significantly high periprocedural mortality and complication rates still limit the indications of BAV. Further efforts are needed to improve the safety and efficacy of BAV.
