Cardiomyopathy III: Hypertrophic Cardiomyopathy01:29

Cardiomyopathy III: Hypertrophic Cardiomyopathy

18
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Mitral Stenosis I: Introduction

20
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...

Mitral Stenosis II: Clinical features and Diagnostic Tests

27
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

23
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...

Area of Science:

  • Cardiovascular Surgery
  • Pathology
  • Oncology

Background:

  • Right ventricular haemangiomas are rare, typically solitary, benign tumors affecting the right heart.
  • Previous literature predominantly documents solitary cases, making multiple occurrences exceptionally uncommon.

Observation:

  • A 49-year-old female presented with four distinct masses within the right ventricle.
  • Three masses originated from the right ventricular free wall, and one was located on the anterior tricuspid valve leaflet.

Findings:

  • Surgical excision of all four tumors was performed.
  • Histopathological analysis confirmed the diagnosis of cavernous haemangioma.
  • Severe tricuspid regurgitation, secondary to tumor excision, necessitated an anteroinferior commissuroplasty.

Implications:

  • This report is the first to describe multiple right ventricular haemangiomas.
  • Highlights the importance of considering multiple lesions in the differential diagnosis of right ventricular masses.
  • Contributes to the limited understanding of the clinical presentation and management of complex ventricular tumors.
