Summary
Yasui conversion effectively treated progressive left ventricular outflow tract (LVOT) obstruction in two cases following initial repair of aortic arch obstruction and ventricular septal defect. This surgical option offers a safe and simple solution for complex congenital heart disease reinterventions.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Progressive left ventricular outflow tract (LVOT) obstruction can occur after primary repair of complex congenital heart defects like aortic arch obstruction and ventricular septal defects.
- Reintervention for LVOT obstruction presents challenges due to patient anatomy and prior surgical history.
Purpose of the Study:
- To report the successful application of Yasui conversion in managing progressive LVOT obstruction post-biventricular repair.
- To highlight Yasui conversion as a viable alternative when other procedures like the modified Konno or Ross operation are not feasible.
Main Methods:
- Case report of two patients with progressive LVOT obstruction after primary repair.
- Surgical intervention using Yasui conversion for LVOT obstruction.
Main Results:
- Successful resolution of LVOT obstruction in both reported cases following Yasui conversion.
- Demonstrated safety and simplicity of the Yasui conversion procedure in this context.
Conclusions:
- Yasui conversion is a safe, simple, and useful surgical option for managing LVOT obstruction after primary biventricular repair, particularly when other methods are contraindicated or difficult.
- This approach provides a valuable solution for specific cases of recurrent or progressive LVOT obstruction in complex congenital heart disease.

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

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.

01:20Mitral Regurgitation I: Introduction
662
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

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...

Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...
