Summary
Parachute mitral valve, a congenital heart defect, often causes mitral stenosis or regurgitation, leading to haemodynamic compromise. Surgical repair is preferred, offering satisfactory outcomes with 84.8% event-free survival.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- Parachute mitral valve is a rare congenital heart defect characterized by abnormal mitral valve geometry and a single papillary muscle.
- It can occur in isolation or as part of Shone syndrome, often leading to significant hemodynamic compromise.
Purpose of the Study:
- To review and analyze the current literature on parachute mitral valve.
- To understand the clinical presentation, surgical management, and outcomes of patients with this condition.
Main Methods:
- A comprehensive literature search was conducted for articles published since 2000.
- Data from 22 articles, encompassing 149 cases of parachute mitral valve, were analyzed.
Main Results:
- Most patients presented with mitral valve stenosis or regurgitation, frequently associated with left heart obstructions.
- Surgical intervention is often necessary, with mitral valve repair being favored over replacement.
- The study reported a satisfactory overall outcome, with an 84.8% event-free survival rate for surgically treated patients.
Conclusions:
- Parachute mitral valve necessitates surgical intervention due to associated left heart obstructions and hemodynamic compromise.
- Mitral valve repair is the preferred surgical approach, associated with favorable long-term outcomes.
- This review highlights the importance of timely surgical management for parachute mitral valve to improve patient survival and quality of life.

01:27Mitral Valve Prolapse I: Introduction
195
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...

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.

145
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...

01:20Mitral Regurgitation I: Introduction
202
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...

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...

166
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...
