Summary
Parachute mitral valve, a congenital heart defect, often involves complex anatomical changes requiring surgical intervention. Most patients, particularly those without associated syndromes, experience mitral regurgitation and may need multiple surgeries with a high risk of adverse events.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Parachute mitral valve is a congenital anomaly affecting mitral valve structure.
- This condition often presents with complex pathological changes beyond the valve leaflets.
Purpose of the Study:
- To review the morphology of parachute mitral valve.
- To discuss the surgical management strategies for parachute mitral valve.
Main Methods:
- Systematic literature search of PubMed, HighWire Press, and Cochrane Library databases.
- Inclusion of 62 English-language articles encompassing 330 parachute mitral valve patients (2000-2018).
- Investigation of mitral valve morphology and surgical treatment options.
Main Results:
- Non-syndromic parachute mitral valve (87%) was more common than syndromic (13%).
- Non-syndromic cases frequently presented with congestive heart failure and mitral regurgitation.
- Syndromic cases were more commonly associated with mitral stenosis.
Conclusions:
- Parachute mitral valve is rarely an isolated defect, involving extensive mitral apparatus pathology.
- The majority of patients require surgical intervention, often multiple operations.
- High incidence of adverse events including reintervention, heart block, and mortality is noted.

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.

01:27Mitral Valve Prolapse I: Introduction
269
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...

206
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...

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...

211
The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

256
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...
