Association of Non-Severe Aortic Stenosis With Left Ventricular Reverse Remodeling and Clinical Outcomes After Cardiac Resynchronization Therapy

Masaki Ishiyama, Naoki Fujimoto, Tetsuji Kitano, Taku Omori et autres

Background: The clinical impact of non-severe aortic stenosis (AS) on the response to cardiac resynchronization therapy (CRT) remains unclear. We investigated whether non-severe AS affects left ventricular (LV) reverse remodeling and long-term outcomes after CRT. Methods and Results: We retrospectively analyzed 181 …

Impact of Preoperative Diuretics Treatment on Long-Term Clinical Outcomes After Transcatheter Aortic Valve Implantation

Shun Hirosawa, Hiroaki Yokoyama, Ken Yamazaki, Shun Shikanai et autres

Diuretics are used to relieve congestive symptoms in patients with severe aortic stenosis (AS). However, the effect of preprocedural diuretic treatment on long-term outcomes in AS patients who undergoing transcatheter aortic valve implantation (TAVI) remains unclear. We prospectively enrolled 4,903 consecutive AS …

Prognostic factors and outcomes in patients under 75 years old receiving transcatheter aortic valve implantation: insights from the LAPLACE registry

Ryotaro Matsuo, S Doi, N Takahashi, H Iwata et autres

Abstract Background Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis. However, from the perspective of prosthetic valve durability, surgical aortic valve replacement (SAVR) is often prioritized in younger patients. The ESC/EACTS Guidelines for the management of valvular …
