Summary
Left ventricular pseudoaneurysm, a rare heart complication, can be challenging to diagnose. This case shows successful surgical repair after diagnosis via multi-angle echocardiography following myocardial infarction.
Area of Science:
- Cardiology
- Cardiac Surgery
- Diagnostic Imaging
Background:
- Left ventricular pseudoaneurysm is a rare, life-threatening complication post-myocardial infarction, surgery, or trauma.
- It arises from myocardial rupture contained by scar tissue, potentially causing hemodynamic instability.
Purpose of the Study:
- To present a case of left ventricular pseudoaneurysm with rupture into the right ventricle.
- To emphasize the diagnostic challenges and successful management of this rare condition.
Main Methods:
- A 62-year-old male patient with post-myocardial infarction left ventricular pseudoaneurysm and right ventricular rupture was treated.
- Diagnosis was confirmed by multi-angle echocardiography after initial studies were inconclusive.
- Successful surgical repair involved pseudoaneurysm excision and rupture/perforation repair.
Main Results:
- The patient underwent successful surgical intervention for left ventricular pseudoaneurysm and associated rupture.
- Postoperative imaging (CT) confirmed successful repair without residual pseudoaneurysm.
- The patient experienced an uneventful recovery with stable cardiac function.
Conclusions:
- Early and accurate diagnosis of cardiac complications like pseudoaneurysms is critical.
- Thorough diagnostic imaging, including multi-angle echocardiography, is essential for identifying challenging cases.
- Surgical intervention can be highly effective for managing left ventricular pseudoaneurysms.

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...
01:21Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
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...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
