Summary

Catheter therapy offers a low-risk alternative to surgery for many congenital heart conditions, including valve stenosis and septal defects. Advances in transcatheter closure and balloon dilation are expanding its role in treating complex heart diseases.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Congenital Heart Disease Treatment

Background:

  • Catheter therapy is increasingly vital for treating congenital heart disease.
  • Vascular and valvular balloon dilations show low mortality and morbidity, with short-term outcomes comparable to surgery.

Purpose of the Study:

  • To review the current applications and efficacy of catheter-based interventions in managing congenital and acquired heart diseases.
  • To highlight established and emerging transcatheter techniques for various cardiac defects.

Main Methods:

  • Review of cumulative experience with balloon dilation for specific valvular and vascular lesions.
  • Assessment of transcatheter device closure for intracardiac and extracardiac communications.
  • Evaluation of embolization techniques for surgical shunts and other interventional procedures.

Main Results:

  • Balloon dilation is accepted for pulmonary stenosis, recurrent coarctation, rheumatic mitral stenosis, and aortic stenosis.
  • Transcatheter closure is established for aortopulmonary collaterals, arteriovenous malformations, and patent ductus arteriosus.
  • Nonsurgical closure of septal defects shows promising early results; blade atrioseptostomy and foreign body retrieval are standard procedures.

Conclusions:

  • Catheter therapy provides effective, less invasive options for numerous congenital and acquired heart conditions.
  • Ongoing improvements and new concepts in catheter interventions will further solidify their role in cardiac care.
