Insights

Intracardiac thrombus formation occurred during an attempted atrial septal defect closure using a device. Prolonged procedure time and multiple device deployments likely caused this complication, necessitating urgent surgical intervention.

Area of Science:

  • Cardiology
  • Medical Devices
  • Surgical Procedures

Background:

  • Atrial septal defects (ASDs) are commonly closed percutaneously using device closure.
  • Device closure of ASDs requires precise deployment and can be challenging in certain anatomies.

Observation:

  • A rare case of intracardiac thrombus formation was observed at the superior vena cava-right atrium junction.
  • This complication arose during an attempted percutaneous closure of an ASD using a device similar to the Amplatzer septal occluder.

Findings:

  • The intracardiac thrombus was likely associated with multiple device deployment attempts and prolonged procedural duration.
  • The patient required urgent surgical closure of the ASD due to the thrombus complication.

Implications:

  • This case highlights a potential risk of intracardiac thrombus formation during complex ASD device closures.
  • Careful procedural planning and execution are crucial to minimize procedural time and device manipulation, thereby reducing thrombosis risk.
  • Further research may be warranted to identify predictive factors and preventative strategies for thrombosis during ASD device closure.

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.

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...
