Summary
This report details an extremely rare, asymptomatic giant left atrial myxoma with unusual ossification and blood supply from the right coronary artery. The findings highlight atypical presentations of common cardiac tumors.
Area of Science:
- Cardiovascular Surgery
- Cardiac Pathology
- Oncology
Background:
- Atrial myxomas are the most common primary cardiac tumors, typically presenting with non-specific symptoms.
- Most myxomas are small to moderate in size and lack ossification.
Observation:
- A case of a giant (12x10 cm) left atrial tumor in an asymptomatic 58-year-old male is presented.
- The tumor was an incidental finding during evaluation for hemoptysis and showed neovascularization from the right coronary artery (RCA).
- Macroscopically, the tumor's size and solid consistency were atypical for a myxoma.
Findings:
- Surgical excision revealed a benign myxoma with significant ossification (mature bone).
- The tumor's blood supply originated from the RCA.
- Pathology confirmed a benign myxoma with excessive osteoid content.
Implications:
- This case underscores the possibility of asymptomatic giant atrial myxomas with rare features like ossification and atypical vascular supply.
- It emphasizes the importance of thorough histopathological examination for accurate diagnosis of cardiac tumors.
- The findings contribute to understanding the diverse presentations of atrial myxomas.

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...
01:22Mitral 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...
01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:27Mitral Valve Prolapse I: Introduction
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...
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...
01:22Mitral Valve Prolapse II: Assessment and Management
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.
