Cardiac Catheterization III: Left Heart Catheterization

1.0K
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

2.2K
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:

  • Cardiovascular Surgery
  • Interventional Cardiology

Background:

  • Transapical aortic valve implantation (TAVI) is an emerging treatment for severe aortic valvular disease.
  • It offers an alternative for patients unsuitable for traditional or transfemoral valve replacement.

Purpose of the Study:

  • To identify complications associated with the initial learning curve of transapical aortic valve implantation.
  • To outline technical and management considerations for this procedure.

Main Methods:

  • Retrospective review of 60 transapical aortic valve implantations in high-risk patients.
  • Analysis of perioperative complications, focusing on apical access site management.
  • Utilized echocardiography and fluoroscopy for procedural guidance.

Main Results:

  • Technical success rate of 98.3% in a high-risk cohort (mean STS score 12.3%).
  • In-hospital/30-day mortality decreased from 33.3% to 13.3% over the learning curve.
  • Key complications included ventricular apical bleeding (5.0%), stroke (3.3%), and pseudoaneurysm (6.6%).

Conclusions:

  • Early experience with transapical aortic valve implantation yielded valuable lessons.
  • These findings can guide broader adoption and refinement of the technique.
