Insights

Coil occlusion is a common treatment for patent ductus arteriosus (PDA). This study found adults experienced more hemolysis complications than children after PDA coil occlusion.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology

Background:

  • Patent ductus arteriosus (PDA) coil occlusion is a standard first-line treatment.
  • Limited data exists on age-related complications of PDA coil occlusion.

Purpose of the Study:

  • To investigate age-dependent differences in complications following coil occlusion for patent ductus arteriosus (PDA).

Main Methods:

  • Retrospective analysis of 16 patients (11 adults, 5 children) with PDA > 3 mm treated with coil occlusion.
  • Evaluation of immediate and intermediate outcomes and complications.

Main Results:

  • Procedural success rates were 72.7% in children and 100% in adults.
  • Coil migration occurred in 4 children and 1 adult.
  • Hemolysis was observed in 3 adult patients, a higher incidence than in children.

Conclusions:

  • Hemolysis is a more frequent complication in adults compared to children undergoing PDA coil occlusion, even with trivial residual shunts.

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
