Background: J-Valve system is one special designed for trans-apical TAVR (Transcatheter aortic valve replacement) with three U-shape graspers. With the unique structure, J-Valve is suitable for both aortic stenosis and aortic regurgitation.We used the J-Valve system and received good clinical results. Methods: From January 2018 to August 2019, 34 patients underwent trans-apical transcatheter valve replacement using the J-Valve system. 11 patients mainly suffered from aortic stenosis, 14 patients had pure aortic regurgitation. Three patients had a ViV aortic valve position, five in mitral valve ViV and one in tricuspid valve. The average preoperative STS score and EuroSCORE II were 8.9% and 8.7%, respectively. Results: The technique success rate was 97.1% and one patient transferred to open surgery intraoperative. 30-day mortality was 5.9% and one patient died because of acute heart attack during follow up. One patient suffered stroke and recovered well, no more other complication was observed perioperative. The rate of perivalvular leak (larger than moderate) was 0% and the rate of mild and trace leak was 6.7% (2/30). The postoperative average flow rate was 2.1m/s and average transvalvular pressure difference was 15mmHg. Conclusions: J-Valve system is a safe and effect method for complex valve disease patients not suitable for open surgery.
