Summary
Transcatheter aortic valve replacement (TAVR) is feasible for inoperable severe aortic stenosis. This study details successful TAVR with cardiopulmonary support (CPS) in patients with low left ventricular function.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Severe aortic stenosis poses risks for inoperable patients.
- Transcatheter aortic valve replacement (TAVR) offers a less invasive option.
- Low left ventricular (LV) function presents unique challenges for TAVR.
Observation:
- Two cases of TAVR were performed in patients with severe aortic stenosis and low LV function.
- Cardiopulmonary support (CPS) was utilized during the TAVR procedures.
- The technique involved TAVR on CPS for patients with compromised LV function.
Findings:
- Successful TAVR outcomes were achieved in both reported cases.
- The use of CPS facilitated TAVR in patients with low LV function.
- The described technique demonstrated feasibility and success in this challenging patient group.
Implications:
- TAVR with CPS may be a viable option for inoperable severe aortic stenosis patients with low LV function.
- This approach could expand treatment options for high-risk cardiac patients.
- Further research is warranted to evaluate the long-term efficacy and safety of TAVR on CPS.

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
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...
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...
01:25Mitral 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...
