Summary
Redo transcatheter aortic valve implantation (TAVI) in patients with small native annuli presents challenges. The Allegra transcatheter heart valve (THV) offers advantages in these complex redo TAVI cases.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Medical Devices
Background:
- Transcatheter aortic valve implantation (TAVI) indications are expanding to younger patients with severe aortic stenosis.
- Increased patient survival leads to a rise in Redo TAVI procedures.
- Small native annuli pose a significant challenge in Redo TAVI.

373
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...

253
Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
