Cardiac Catheterization III: Left Heart Catheterization

1.2K
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...

Cardiac Catheterization I: Pre-Procedure Overview

2.9K
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Pediatric Cardiology

Background:

  • Early failure of the Fontan circulation, though rare, carries a high mortality risk.
  • Surgical Fontan takedown is an established strategy to stabilize circulation and improve survival.
  • This procedure allows for potential future Fontan completion.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of transcatheter Fontan takedown in patients with early Fontan circulation failure.
  • To assess the efficacy of this minimally invasive approach in managing complications associated with Fontan failure.

Main Methods:

  • Transcatheter Fontan takedown was performed in three pediatric patients with extracardiac conduits.
  • Procedures involved occluding the conduit to redirect superior vena cava flow to pulmonary arteries.
  • Stenting and fenestration enlargement redirected inferior vena cava flow to the atrium.

Main Results:

  • No procedure-related complications occurred.
  • All patients experienced resolution of chylous pleural effusions.
  • One patient's protein-losing enteropathy resolved, and two improved from plastic bronchitis.
  • Two of three patients survived at 4-24 months follow-up.

Conclusions:

  • Transcatheter Fontan takedown is technically feasible in select patients with early Fontan circulation failure.
  • It may serve as a viable alternative to surgical takedown.
  • This approach can effectively manage complications like effusions and bronchitis.
