Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

1.2K
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

396
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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

643
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...

Cardiovascular System Abnormal Findings II: Auscultation

751
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

873
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 Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

916
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...

Summary

A rare cardiac hemangioma was incidentally found in an asymptomatic 45-year-old man. Surgical resection was successful, highlighting it as the preferred treatment for this benign cardiac tumor.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Oncology

Background:

  • Cardiac hemangiomas are rare benign cardiac tumors, comprising 5-10% of such cases.
  • Clinical presentations typically include dyspnea on exertion and arrhythmia, with asymptomatic cases being uncommon.

Observation:

  • An asymptomatic 45-year-old man presented with an incidentally discovered left ventricular mass during an echocardiogram.
  • Magnetic resonance imaging revealed an isointense, protruding mass on the lateral wall of the left ventricle.

Findings:

  • Histopathological examination confirmed the mass as a cavernous hemangioma.
  • The patient underwent successful complete surgical resection of the cardiac hemangioma.

Implications:

  • This case underscores the importance of considering rare diagnoses even in asymptomatic patients.
  • Complete surgical resection is the favored treatment for cardiac hemangiomas due to variable natural courses.
  • Successful resection offers a good prognosis for patients with cardiac hemangiomas.
