Insights

Early surgical repair of common atrioventricular canal defects (CAVCD) is safe and effective. This study shows good early and long-term outcomes for patients undergoing CAVCD repair, emphasizing individualized early intervention.

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Surgery
  • Cardiovascular Research

Background:

  • Established policy of elective repair for common atrioventricular canal defects (CAVCD) in infants aged 8-12 weeks.
  • Long-term evaluation of a 20-year surgical experience with CAVCD repair.

Purpose of the Study:

  • To assess the outcomes of a 20-year policy of elective CAVCD repair in infants.
  • To identify factors influencing reoperation and long-term valve performance.

Main Methods:

  • Retrospective review of 159 consecutive patients undergoing CAVCD repair (January 1992 - April 2014).
  • Surgical techniques included double-patch (86%) and modified single-patch (14%).
  • Analysis of operative mortality, late mortality, reoperation rates, and left atrioventricular valve (LAVV) performance.

Main Results:

  • 3 operative (1.9%) and 12 late (7.7%) deaths occurred.
  • 13% of patients required reoperation, primarily for LAVV regurgitation (10%).
  • LAVV dysplasia and cleft closure were associated with increased reoperation risk; older age at repair (>3 months) and LAVV dysplasia worsened late LAVV performance.

Conclusions:

  • Individualized early repair of CAVCD is a safe and beneficial strategy.
  • The study demonstrates good early and long-term results supporting this approach.
  • Attention to LAVV status and timing of repair is crucial for optimal outcomes.

Chambers of the Heart01:16

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Mitral 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...

Mitral 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...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

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 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...

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
