An alternative solution for patient with high risk of coronary obstruction underwent TAVI procedure using a novel second-generation device – a case series

Background Obstruction of the left or right coronary artery is a rare but lethal complication during transcatheter aortic valve implantation (TAVI). The new J-Valve™ prosthesis is a new second generation TAVI device which has several features to avoid the coronary obstruction such as low profile design and clip fixation of the native leaflets. The aim of this study is to report our initial experience of using this valve in treating patient with high risk factors for coronary obstruction during TAVI procedure.
