Summary
Selecting the correct transcatheter aortic valve replacement (TAVR) size for bicuspid aortic valves (BAV) is crucial. Balloon predilatation with contrast can help determine the optimal TAVR valve size in challenging BAV cases.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Imaging
Background:
- Transcatheter aortic valve replacement (TAVR) is a common treatment for aortic stenosis.
- Bicuspid aortic valve (BAV) anatomy presents unique challenges for TAVR device selection.
- Accurate valve sizing is critical to minimize complications like paravalvular leak and aortic injury.

01:26Mitral 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...
01:25Aortic 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...
