Summary
Cor triatriatum with complete atrioventricular septal defect is a rare congenital heart defect. This case study details successful surgical repair in an infant, achieving normal cardiac function post-operation.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Pediatric Cardiac Surgery
Background:
- Cor triatriatum (CT) is a rare cardiac anomaly involving left atrial partitioning.
- Association of CT with atrioventricular septal defects (AVSD) is exceptionally uncommon.
- Few cases of CT combined with complete AVSD have been previously documented.
Observation:
- An 11-month-old female infant presented with a rare combination of complete atrioventricular septal defect and cor triatriatum.
- The infant underwent surgical correction for both cardiac anomalies.
Findings:
- The patient experienced an uneventful recovery following surgical intervention.
- Normal cardiac performance was successfully restored 2 years after the surgery.
Implications:
- This case highlights the feasibility of surgical correction for complex congenital heart defects like CT and complete AVSD in infants.
- Successful surgical outcomes underscore the importance of early diagnosis and intervention for rare cardiac anomalies.
- Further research into the management of combined CT and AVSD may improve clinical guidelines and patient outcomes.

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.

01:22Mitral 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...
01:20Mitral 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...
01:15Aortic 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...
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...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
