Summary
A rare congenital left ventricular (LV) diverticulum ruptured, causing a pseudoaneurysm in a 41-year-old woman presenting with chest tightness. Surgical repair was successful, confirming the congenital origin.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Congenital left ventricular (LV) diverticulum is a rare condition.
- LV diverticula can present with various complications, including pseudoaneurysm formation.
- Diagnosis and management require a multidisciplinary approach.
Observation:
- A 41-year-old woman presented with chest tightness and shortness of breath.
- Transthoracic echocardiogram revealed a left ventricular pseudoaneurysm of the inferior wall.
- Coronary angiography showed normal coronary arteries.
Findings:
- Pathological examination confirmed the pseudoaneurysm resulted from a ruptured isolated congenital LV diverticulum.
- Left ventricular systolic function was preserved despite the pseudoaneurysm.
- Surgical repair using a pericardial patch was successfully performed.
Implications:
- This case highlights the importance of considering congenital LV diverticulum in the differential diagnosis of LV pseudoaneurysms.
- Early diagnosis and surgical intervention are crucial for favorable outcomes.
- Understanding the etiology of LV pseudoaneurysms can guide treatment strategies.

Aneurysm I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Aortic Regurgitation I: Introduction
330
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...

Mitral Valve Prolapse I: Introduction
238
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...

Mitral Stenosis I: Introduction
261
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...

Development of the Heart
1.8K
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.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Mitral Regurgitation I: Introduction
281
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...
