Summary
Ventricular septation offers a viable biventricular repair for double inlet left ventricle (DILV). This surgical approach provides a long-term survival alternative to the Fontan operation for select single-ventricle patients.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Congenital Heart Disease
Background:
- Functionally univentricular hearts present complex surgical challenges.
- Double inlet left ventricle (DILV) is a specific type of single-ventricle defect.
- Surgical options for DILV aim to create a biventricular physiology.
Purpose of the Study:
- To evaluate the long-term outcomes of ventricular septation in patients with DILV.
- To assess the efficacy of ventricular septation as an alternative to the Fontan operation for DILV.
- To determine the survival rates following ventricular septation for DILV.
Main Methods:
- Retrospective analysis of 34 patients with DILV undergoing ventricular septation between 1971 and 2000.
- Data collection included in-hospital and late mortality, and follow-up duration.
- Actuarial survival rates were calculated over extended periods.
Main Results:
- Seven hospital deaths and two late deaths were recorded among the 34 patients.
- The mean follow-up period was 15 years.
- Actuarial survival rates remained consistent at 73.3% at 15, 20, 25, and 30-40 years post-surgery.
Conclusions:
- Ventricular septation is a feasible and effective surgical treatment for selected patients with DILV.
- This procedure provides a durable alternative to the Fontan operation, offering significant long-term survival.
- Ventricular septation represents a valuable option in the management of complex congenital heart defects like DILV.

01:16Chambers 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.

01:27Development of the Heart
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.

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...
01:16Heart Valves
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

01:21Coronary Circulation
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

01:20Mitral 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...
