Summary
This report details a rare case of left main coronary artery atresia in a 33-year-old male. Surgical revascularization successfully treated severe angina and prevented sudden cardiac death.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiovascular Surgery
Background:
- Left main coronary artery atresia is an extremely rare congenital anomaly.
- It can lead to severe symptoms like angina pectoris and dyspnea, and poses a high risk of sudden cardiac death.
Observation:
- A 33-year-old male presented with severe angina pectoris and dyspnea.
- Coronary angiography revealed an atretic left coronary artery (LCA) ostium, with retrograde filling via collateral vessels from the dilated right coronary artery (RCA).
- Multislice computed tomography confirmed the diagnosis.
Findings:
- The patient underwent successful coronary artery revascularization.
- A left internal mammary artery graft was anastomosed to the left anterior descending artery.
- The patient experienced an uneventful 24-month follow-up period.
Implications:
- This case highlights the importance of early diagnosis and surgical intervention for left main coronary artery atresia.
- Successful revascularization can alleviate symptoms and reduce the risk of sudden cardiac death in affected individuals.
- Coronary artery bypass grafting using the internal mammary artery is a viable treatment option.

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...

01:22Mitral 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...
01:24Cardiac Catheterization III: Left Heart Catheterization
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...
01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
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...
01:25Cardiovascular 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.
