Summary
Transcatheter aortic valve implantation is safe and effective in patients with prior mitral valve ring repair. The procedure showed no interference with the mitral annuloplasty ring or function.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Limited data exist on transcatheter aortic valve implantation (TAVI) post-mitral valve ring repair.
- Potential interference between TAVI devices and mitral annuloplasty rings is a concern.
Observation:
- A 76-year-old woman with severe aortic stenosis and prior "undersized" mitral annuloplasty for functional mitral regurgitation underwent TAVI.
- Echocardiography monitored mitral function and regurgitation during the procedure.
Findings:
- Percutaneous self-expandable aortic valve implantation showed no deformation of the TAVI device (CoreValve).
- No distortion, malfunction, or conformational changes were observed in the mitral annuloplasty ring.
- Mitral valve function and regurgitation remained unchanged post-procedure.
Implications:
- TAVI is a feasible option for patients with prior mitral valve repair.
- This case suggests TAVI can be safely performed without compromising mitral valve integrity.
- Further studies are warranted to confirm these findings in a larger cohort.

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...
01:22Mitral Valve Prolapse II: Assessment and Management
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.
01:25Mitral Regurgitation III: Medical Management
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...
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...
