Summary
Postoperative ventricular septal function is reduced in children with multiple ventricular septal defects, particularly when large patches are used for closure. Minimizing patch material may preserve function.
Area of Science:
- Pediatric Cardiology
- Cardiac Surgery
- Echocardiography
Background:
- Assessed global and regional ventricular septal function in children with postoperative multiple ventricular septal defects (VSDs).
- Utilized conventional echocardiography and 2D speckle tracking imaging (STI).
Purpose of the Study:
- To evaluate the impact of surgical closure techniques on ventricular septal function in children with multiple VSDs.
- To correlate patch material usage with postoperative cardiac function.
Main Methods:
- Studied 36 children (16 with postoperative multiple VSDs, 20 controls).
- Analyzed 60 VSD closures using patch, sandwich, or direct techniques.
- Applied STI to three short-axis echocardiographic views.
Main Results:
- Total patch area correlated with reduced ejection fraction and Tei index.
- Global septal function (displacement and strain) was significantly lower in the VSD group.
- Patch and sandwich techniques showed reduced regional function compared to intact segments; direct closure had no significant regional depression.
Conclusions:
- Postoperative ventricular and septal functions are significantly reduced in children with multiple VSDs, especially with complex disease and large prosthetic material use.
- Minimizing patch material may help preserve postoperative ventricular function.

01:22Mitral Stenosis I: Introduction
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...
01:28Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
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...
01:27Mitral Valve Prolapse I: Introduction
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...
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...

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...
