Summary
Tricuspid regurgitation repair in rheumatic heart disease is challenging. A novel leaflet augmentation technique with a pericardial patch and annuloplasty ring effectively restored valve function in a complex case.
Area of Science:
- Cardiology
- Cardiac Surgery
- Valvular Heart Disease
Background:
- Tricuspid regurgitation is common and debilitating in rheumatic heart disease patients post-left-sided valve replacement.
- Surgical repair of the tricuspid valve is preferred but technically demanding.
Purpose of the Study:
- To present a novel surgical technique for complex rheumatic tricuspid regurgitation.
- To evaluate the efficacy of leaflet augmentation with a pericardial patch and partial annuloplasty ring.
Main Methods:
- A 60-year-old female patient with severe tricuspid regurgitation underwent repair via median sternotomy and cardiopulmonary bypass.
- The technique involved leaflet detachment, augmentation with a bovine pericardial patch, and implantation of a partial rigid annuloplasty ring.
Main Results:
- Intra-operative echocardiography confirmed trace residual tricuspid regurgitation.
- The patient experienced an uneventful recovery with early resolution of symptoms like leg edema.
Conclusions:
- Leaflet augmentation combined with partial ring annuloplasty is a simple, reproducible technique for rheumatic tricuspid regurgitation.
- This approach restores early valve competence, though long-term durability requires further study.

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

691
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...

599
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...

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
