Insights

A giant left atrial ball thrombus caused acute heart failure and syncope by blocking blood flow. Surgical removal resolved the obstruction and symptoms in this patient.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Pathology

Background:

  • Acute heart failure and syncope can present with various underlying cardiac pathologies.
  • Left atrial masses, though uncommon, pose significant risks due to potential hemodynamic compromise.

Observation:

  • A 70-year-old female presented with acute heart failure and near syncope.
  • Transthoracic and transesophageal echocardiography revealed a large, mobile left atrial mass (4.9 x 3.9 cm).
  • The mass obstructed the left ventricular inflow tract supravalvularly, despite normal mitral valve leaflets.

Findings:

  • The resected left atrial mass was pathologically confirmed as thrombus, consistent with a left atrial ball thrombus (LABT).
  • The obstruction of the left ventricular inflow tract by the giant LABT was the direct cause of the patient's acute diastolic heart failure and syncope.

Implications:

  • Giant LABTs are a critical cause of acute heart failure and syncope, necessitating prompt diagnosis and intervention.
  • Emergent surgical excision is crucial for managing symptomatic LABTs causing significant hemodynamic compromise.
  • This case highlights the importance of echocardiography in identifying intracardiac masses and guiding urgent surgical management.

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

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...

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...

Mitral Stenosis I: Introduction

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

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

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...
