Transcatheter Aortic Valve Replacement Using Echocardiography Guidance for Severe Aortic Stenosis in High-Risk Patients

What this Trial Is About

This research focuses on patients with symptomatic severe aortic stenosis AS who require aortic valve replacement. It explores a method called echocardiography-guided transcatheter aortic valve replacement Echo TAVR as a safer alternative to the conventional TAVR, which usually uses fluoroscopy and contrast agents. This approach is particularly important for high-risk patients who should avoid radiation and contrast exposure. The procedure uses echocardiography instead of traditional imaging methods to guide the valve replacement. This method aims to reduce risks associated with radiation and contrast agents, making it a potentially safer option for certain patients. The study observes patients undergoing this echocardiography-guided procedure without comparing to other treatments. Participants in the study will be monitored for outcomes related to the safety and effectiveness of the Echo TAVR procedure. The main measure will be the Valve Academic Research Consortium-3 VARC-3 criteria assessed 30 days after surgery. The study will collect data on clinical results following the procedure to evaluate this newer guidance method. Participation involves follow-up evaluations around one month after treatment.
