|September 8, 2014
Summary
A rare double-orifice mitral valve in a child with an atrioventricular septal defect was successfully repaired. The innovative surgical technique corrected mitral insufficiency, restoring normal heart function.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Congenital Heart Disease
Background:
- Partial atrioventricular septal defects (AVSD) are congenital heart conditions that can lead to mitral valve abnormalities.
- Mitral insufficiency, particularly secondary to leaflet abnormalities, poses a significant surgical challenge in pediatric patients.
Observation:
- An eight-year-old female presented with moderate mitral insufficiency and a partial AVSD.
- Echocardiography revealed an ostium primum atrial septal defect and a unique double-orifice mitral valve with an anterior leaflet cleft and prolapse.
- Intraoperative findings confirmed the double-orifice mitral valve structure with shared papillary muscle attachments.
Findings:
- Successful mitral valve repair was achieved through chordal shortening and cleft closure.
- Postoperative assessment showed trivial mitral regurgitation (MR) and no evidence of mitral stenosis.
Implications:
- This case highlights the feasibility and success of surgical mitral valve repair in complex congenital heart anomalies.
- The presented technique offers a valuable approach for managing double-orifice mitral valves, improving long-term outcomes in pediatric cardiac surgery.
- Accurate echocardiographic and intraoperative evaluation is crucial for planning effective surgical interventions in congenital mitral valve disease.

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 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.
01:20Mitral 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...
01:25Mitral 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...
01:22Mitral 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.
