Cardiac Catheterization III: Left Heart Catheterization

421
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Interventional Cardiology

Background:

  • The extracardiac Fontan procedure is a critical surgical intervention for complex single-ventricle congenital heart disease.
  • Previous techniques aimed to anatomically and hemodynamically replicate the standard extracardiac Fontan.
  • Simplification and wider applicability of this procedure remain areas of interest.

Purpose of the Study:

  • To describe modifications to a previously reported technique for extracardiac Fontan procedure.
  • To simplify the procedural sequence for potentially wider application.
  • To detail methods for percutaneous completion and fenestration.

Main Methods:

  • The study describes modifications to an existing technique for extracardiac Fontan completion.
  • Percutaneous completion is achieved using electrocautery, without reliance on a radiofrequency probe.
  • Fenestration is presented as an easily performable option when clinically indicated.

Main Results:

  • The modified technique simplifies the original procedural sequence.
  • Percutaneous completion is feasible using electrocautery.
  • Fenestration can be readily performed if necessary.

Conclusions:

  • The described modifications simplify the extracardiac Fontan procedure.
  • These simplifications may allow for wider application of the technique.
  • The procedure effectively mimics standard extracardiac Fontan hemodynamics and anatomy.
