Summary
A rare isolated cleft in the anterior mitral leaflet caused severe mitral regurgitation. Minimally invasive repair using direct closure and annuloplasty proved successful in an adult patient.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Disease
- Minimally Invasive Procedures
Background:
- Isolated clefts of the mitral valve leaflet are an uncommon cause of mitral regurgitation in adults.
- Severe mitral regurgitation necessitates effective treatment strategies.
Observation:
- A large cleft, measuring 5x8 mm, was identified in the center of the anterior mitral leaflet.
- The mitral valve was visualized effectively using a video-assisted minimally invasive approach via the right chest.
Findings:
- Successful direct closure of the isolated anterior mitral leaflet cleft was performed.
- Annuloplasty was completed using a 30-mm Carpenter-Edwards Physio Ring.
Implications:
- Minimally invasive mitral valve repair is a viable option for severe mitral regurgitation due to isolated clefts.
- Video-assisted thoracic surgery offers excellent visualization for complex mitral valve repairs.

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...
01:27Mitral 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...
01:23Mitral 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...
01:25Mitral Regurgitation III: Medical Management
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...
01:28Mitral Regurgitation IV: Nursing Management
Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...
