Mitral Valve Prolapse II: Assessment and Management01:22

Mitral Valve Prolapse II: Assessment and Management

204
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...

Mitral Valve Prolapse I: Introduction

196
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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

236
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

204
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...

Aortic Regurgitation I: Introduction

261
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Heart Valves

10.1K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Cardiac Surgery

Background:

  • Parachute tricuspid valve is an exceedingly rare congenital cardiac anomaly.
  • Its morphological characteristics and clinical significance remain incompletely understood.
  • This systematic review aims to elucidate these aspects.

Purpose of the Study:

  • To comprehensively review the literature on parachute tricuspid valve.
  • To describe its morphological and clinical features.
  • To discuss diagnostic modalities, treatment strategies, and patient outcomes.

Main Methods:

  • Systematic review adhering to PRISMA guidelines.
  • Literature search across PubMed, Highwire Press, and Cochrane Library databases.
  • Inclusion of 13 reports comprising 14 patients diagnosed between 1979 and 2019.

Main Results:

  • A single papillary muscle in the right ventricle was a consistent finding.
  • Tricuspid valve dysfunction varied, including regurgitation (60%), stenosis (30%), and normal function (10%).
  • 40% of patients were asymptomatic or mildly symptomatic; 60% required surgical/interventional treatment for severe symptoms or associated defects.

Conclusions:

  • Parachute tricuspid valve management depends on symptom severity and associated cardiac anomalies.
  • Surgical or interventional treatment is indicated for severe symptoms, right ventricular inflow obstruction, or tricuspid stenosis.
  • Patient outcomes are variable, with a reported survival rate of 70%.
