Additional Information

Official title A Clinical Trial of a 20mm Transcatheter Bioprosthetic Valve for Patients With Aortic Stenosis
Principal investigator Morimasa Takayama, MD
Description Purpose: To evaluate the safety and efficacy of THV-9300 (20mm) for patients who have severe symptomatic aortic stenosis attributed to calcification and degeneration of a valve leaflet and for whom undergoing a surgery safely would be difficult. Enrollment: 15 patients (No.of patients needed: 12) Follow-up: Subject data collection will include clinical information at baseline and during the index procedure. Subjects will undergo clinical follow-up at discharge, 30 days, 6 months and annually for 5 years. Clinical sites: 1)Osaka University Hospital, 2)Kurashiki Central Hospital, 3)Sakakibara Heart Institute, 4) Kokura Memorial Hospital
