Summary
Mechanical leaflet modification (LM) offers a new solution for preventing coronary obstruction during transcatheter aortic valve replacement (TAVR) in patients with native aortic stenosis. This novel technique shows promise for improving TAVR safety.
Area of Science:
- Cardiovascular Interventions
- Structural Heart Disease
- Interventional Cardiology
Background:
- Coronary obstruction is a critical risk during transcatheter aortic valve replacement (TAVR).
- Mechanical leaflet modification (LM) is established for degenerated bioprostheses but not for native valves.
- Native aortic valve disease presents unique challenges for TAVR procedures.

Aortic Regurgitation III: Medical Management
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...
Mitral Stenosis III: Medical Management
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...
