Summary
Annular sub-mitral aneurysms are rare cardiac defects. This case report details a calcified variant, emphasizing pre-operative imaging and surgical considerations for successful management.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Imaging
Background:
- Annular sub-mitral aneurysms are uncommon cardiac lesions with diverse causes.
- A sub-mitral membrane may predispose individuals to aneurysm formation.
- These aneurysms originate from the atrioventricular groove, near the mitral valve's mural leaflet.
Observation:
- The case involves a calcified, bi-lobed sub-mitral aneurysm with a left atrial connection.
- Lesions can cause mass effects, mitral regurgitation, and impaired left ventricular function.
- Surgical repair is complex due to proximity to the circumflex artery, atrioventricular junction, and mitral valve.
Findings:
- Computed tomogram angiography is crucial for detailed pre-operative anatomical assessment.
- Understanding the anatomical basis is key to managing these rare aneurysms.
- The report highlights the surgical approach for this specific calcified variant.
Implications:
- Accurate pre-operative imaging aids in planning complex cardiac surgeries.
- Improved understanding of sub-mitral aneurysm anatomy can refine surgical techniques.
- This case contributes to the literature on rare cardiac pathologies and their management.

01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
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...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:25Cardiovascular System Abnormal Findings II: Auscultation
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

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...

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
