Summary
Ruptured chordae tendineae can cause severe mitral insufficiency in adults, presenting with a unique murmur and acute pulmonary edema. Early diagnosis and mitral valve replacement offer significant patient improvement.
Area of Science:
- Cardiology
- Cardiac Surgery
Background:
- Mitral insufficiency due to ruptured chordae tendineae is a distinct clinical entity.
- Understanding its presentation and outcomes is crucial for timely intervention.
Observation:
- Seven adult patients presented with mitral insufficiency from ruptured chordae tendineae.
- Key findings included adult-onset systolic murmur mimicking aortic stenosis, acute pulmonary edema with normal left atrial size, and variable left ventricular size.
Findings:
- Three patients underwent successful mitral valve replacement, showing dramatic clinical improvement.
- Two patients were diagnosed and are awaiting potential surgery, while two died before intervention.
- Myxomatous degeneration was noted, but the etiology of chordal rupture remains unknown.
Implications:
- This condition, though etiology is uncertain, may be more common than previously thought.
- Prompt diagnosis and surgical management of mitral insufficiency from ruptured chordae tendineae can lead to favorable outcomes.
- Further research into the incidence and causes of ruptured chordae tendineae is warranted.

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...
01:20Mitral 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...
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...
01:26Mitral Stenosis III: Medical Management
Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage. Timely...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
