Insights

Transcatheter closure for atrial septal defects (ASDs) can rarely cause erosion. A child developed life-threatening pericardial effusion due to device erosion, requiring surgical repair.

Area of Science:

  • Cardiology
  • Medical Devices
  • Pediatric Cardiology

Background:

  • Transcatheter device closure is the primary treatment for secundum atrial septal defects (ASDs).
  • The Amplatzer septal occluder (ASO) is a commonly used device for ASD closure.

Observation:

  • A seven-year-old child with secundum ASD underwent successful transcatheter device closure.
  • Two weeks post-procedure, the patient developed acute pericardial effusion.
  • Diagnosis revealed erosion of the atrial roof by the implanted device.

Findings:

  • Echocardiography and cardiac CT confirmed atrial roof erosion by the ASO.
  • The patient required surgical intervention for device removal and atrial tear repair.
  • Successful surgical closure of the ASD and repair of the atrial tear were performed.

Implications:

  • Cardiac erosion is a rare but serious complication of transcatheter ASD device closure.
  • This complication can be life-threatening and necessitates prompt diagnosis and management.
  • Clinicians should maintain a high index of suspicion for cardiac erosion in patients presenting with effusion post-procedure.

Esophageal Perforation-I: Introduction01:22

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
