Insights

A rare case of cardiac strangulation caused by a pacemaker lead in a child with congenital heart block is presented. Surgical intervention successfully removed the lead and implanted a new system, preventing recurrence.

Area of Science:

  • Pediatric Cardiology
  • Cardiac Electrophysiology
  • Cardiovascular Surgery

Background:

  • Congenital complete atrioventricular block requires pacemaker implantation.
  • Permanent epicardial pacemaker leads can pose long-term risks.

Observation:

  • An 8-year-old boy with a history of congenital heart block presented with pulmonary and mitral stenosis.
  • Echocardiography, CT, and cardiac catheterization revealed pacemaker lead encirclement of the heart, termed "cardiac strangulation".

Findings:

  • The patient underwent removal of the constricting pacemaker lead and generator.
  • A new dual-chamber epicardial pacing system was implanted.
  • An expanded polytetrafluoroethylene sheet was used to prevent lead adherence and recurrence.

Implications:

  • This case highlights a rare but serious complication of epicardial pacemaker leads in pediatric patients.
  • Careful lead placement and follow-up are crucial in managing congenital heart block.
  • Surgical techniques can effectively address and prevent cardiac strangulation complications.

Cardiac Catheterization II: Right Heart Catheterization

Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

Introduction Cardiac Emergencies

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

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...
