The ACURATE Neo2 valve is an evolution of the first-generation ACURATE Neo valve with a low rate of pacemaker implantation and a decrease in paravalvular leak, also compatible with the 14F introducer. This prospective study included patients with symptomatic severe aortic stenosis at high surgical risk who underwent ACURATE Neo2 valve implantation. The primary endpoint…
The Physiopathology Behind Valve Degeneration in TAVR
The degeneration of transcatheter biological valves clearly depends on time and starts with thrombus generation and subsequent histological changes resulting in valve failure (due to regurgitation, stenosis, or both). Thrombus formation is the first change, observed early in computerized tomography (CT) scans after implantation. Most times it is completely asymptomatic, which leaves many of us…
Tricuspid valve repair with the MitraClip technique
Current surgical and medical treatment options for severe tricuspid regurgitation are extremely limited. However, this historically forgotten valve seems to have the option of transcatheter repair, nowadays. This observational study assessed the safety and feasibility of the MitraClip system for patients with severe chronic tricuspid regurgitation. All patients presented severe tricuspid regurgitation and…
