Insights

A large cardiac lipoma in the ventricular septum was successfully resected in a 45-year-old man. This rare case highlights diagnostic imaging and surgical management of cardiac tumors.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Diagnostic Imaging

Background:

  • Cardiac lipomas are rare, benign tumors originating from mature adipose tissue.
  • Symptomatic cardiac lipomas can cause significant hemodynamic compromise.

Observation:

  • A 45-year-old male presented with a systolic murmur, leading to the discovery of a large ventricular septal mass.
  • Imaging studies including echocardiography, CT, and MRI confirmed a cardiac lipoma with specific attenuation and signal characteristics.
  • The mass caused a pressure gradient and bulged into the right ventricle.

Findings:

  • Surgical resection via cardiopulmonary bypass was performed, yielding a 6.5 cm yellow, soft tumor.
  • Histological examination confirmed mature fatty tissue within myocardial fibers.
  • Post-operative complications included ventricular septal split and left-to-right shunt, managed with primary closure and patch reinforcement.

Implications:

  • This case underscores the importance of advanced imaging in diagnosing cardiac lipomas.
  • Successful surgical management is feasible for symptomatic ventricular septal lipomas.
  • Postoperative conduction abnormalities, such as left axis deviation and right bundle branch block, can occur due to surgical manipulation.

Anatomy of the Brain: Ventricles

There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
Chambers of the Heart01:16

Chambers of the Heart

The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Mitral Valve Prolapse I: Introduction

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 II: Clinical features and Diagnostic Tests

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

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...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
