Summary
Transcatheter aortic valve-in-valve (TAV-in-V) in a Lotus valve is feasible for high-risk patients. Careful planning and coronary protection strategies ensure successful outcomes, preventing complications like coronary obstruction.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Device Technology
Background:
- Transcatheter aortic valve-in-valve (TAV-in-V) procedures are increasingly used for degenerated bioprosthetic valves.
- The Lotus valve presents unique challenges for TAV-in-V due to its design and potential for coronary obstruction.

246
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...

01:25Aortic Regurgitation III: Medical Management
396
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
