Summary
This case report highlights a rare cardiac myxoma on the mitral valve, a common primary heart tumor. Surgical resection is the only effective treatment to prevent recurrence.
Area of Science:
- Cardiology
- Cardiac Surgery
- Pathology
Background:
- Cardiac myxomas are the most frequent primary cardiac tumors, typically found in the interatrial septum.
- Surgical excision is the definitive treatment for cardiac myxomas.
- Mitral valve involvement by myxoma is exceptionally rare.
Observation:
- A 69-year-old patient presented with dyspnea and lipothymia, alongside significant aortic stenosis.
- Echocardiography and transesophageal echocardiography revealed a 15mm mass on the mitral valve's posterolateral leaflet, initially suspected as myxoma or fibroelastoma.
- Intraoperative findings confirmed a sessile mass on the mitral valve's auricular wall.
Findings:
- Post-surgical histopathological analysis confirmed the mass as a cardiac myxoma.
- The patient underwent successful aortic valve replacement with a mechanical prosthesis.
- The patient experienced an uneventful recovery and was discharged on postoperative day 8.
Implications:
- This case underscores the rarity of mitral leaflet myxomas and the importance of surgical management.
- Complete surgical resection with wide margins is crucial to minimize the risk of myxoma recurrence.
- Comprehensive cardiac evaluation and management are essential for patients with cardiac tumors.

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...

369
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
760
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...

01:22Mitral Stenosis I: Introduction
976
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...

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...

Mitral regurgitation (MR) is characterized by retrograde blood circulation from the left ventricle into the left atrium due to inadequate mitral valve closure. The severity of the condition, symptoms, and underlying cause determine treatment strategies.Monitoring and Pharmacological TreatmentPatients with mild to moderate MR typically do not need immediate intervention but regular monitoring to assess progression and guide treatment. Patients with mild MR should have an echocardiogram every 3-5...
