Summary
Transcatheter tricuspid valve intervention (TTVI) shows promising procedural success and low early mortality in patients with previous left valve surgery (PLVS). Midterm follow-up reveals rehospitalization or death in about one-third, highlighting the need for earlier treatment.
Area of Science:
- Cardiology
- Interventional Cardiology
- Valvular Heart Disease
Background:
- Limited data exists on transcatheter tricuspid valve intervention (TTVI) outcomes in patients with previous left valve surgery (PLVS).
- Understanding these outcomes is crucial for managing complex valvular heart disease.
Purpose of the Study:
- To investigate the procedural and early clinical outcomes of TTVI in patients with PLVS.
- To compare outcomes between patients with and without a history of PLVS.
Main Methods:
- A subanalysis of the multicenter TriValve registry was performed.
- 82 patients with PLVS were compared to patients without PLVS, using propensity score matching.
Main Results:
- Patients with PLVS were younger and more frequently female.
- Procedural success rates (80.5% vs 82.1%) and 30-day mortality (2.4% vs 3.4%) were similar between groups.
- Midterm follow-up showed no significant differences in rehospitalization or mortality after matching.
Conclusions:
- TTVI is a viable alternative to redo surgery for patients with PLVS, demonstrating high procedural success and low early mortality.
- Despite initial success, about one-third of PLVS patients faced rehospitalization or death at midterm, underscoring the importance of timely intervention.

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...

109
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
122
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
168
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...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

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...
