Summary
Mitral valve myxomas are rare cardiac tumors. This report details two cases in women, highlighting their varied presentations and successful surgical removal, underscoring good prognosis after resection.
Area of Science:
- Cardiology
- Cardiac Surgery
- Oncology
Background:
- Primary cardiac tumors are rare, with myxomas being the most common.
- Mitral valve myxomas represent an exceptionally infrequent subset of cardiac myxomas.
Purpose of the Study:
- To report and discuss two distinct cases of mitral valve myxomas.
- To highlight the varied clinical presentations and management of these rare tumors.
- To emphasize the favorable prognosis following surgical intervention.
Main Methods:
- Retrospective review of two mitral valve myxoma cases diagnosed over 12 years.
- Surgical resection of cardiac masses.
- Post-operative follow-up including re-operation in one case.
Main Results:
- Two female patients (25 and 72 years old) presented with mitral valve myxomas.
- Presentations ranged from significant left ventricular inflow obstruction to minor flow divergence.
- Both patients underwent successful surgical resection with good outcomes.
- One patient required re-operation due to prosthetic valve obstruction, with no confirmed recurrence.
Conclusions:
- Mitral valve myxomas, though rare, can present differently.
- Prompt surgical resection is crucial for favorable outcomes.
- The macroscopic appearance may suggest malignancy, but prognosis is generally good post-excision.

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...
01:22Mitral 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...
01:22Mitral 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.
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...
01:23Mitral Regurgitation II: Clinical Features and Diagnostic Tests
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...
