Cardiac Catheterization III: Left Heart Catheterization

968
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

2.0K
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...

Imaging Studies for Cardiovascular System III: X-Ray

564
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Technology

Background:

  • Catheter ablation is the primary treatment for supraventricular tachycardia (SVT).
  • Traditional catheter ablation relies heavily on fluoroscopy for catheter visualization.
  • Advancements in 3D mapping technology offer alternatives to reduce or eliminate fluoroscopy.

Purpose of the Study:

  • To review an 8-year experience with a zero-fluoroscopy catheter ablation approach.
  • To discuss techniques for minimizing fluoroscopy in SVT ablation.
  • To evaluate the feasibility of performing ablations outside the traditional catheterization lab.

Main Methods:

  • A retrospective review of 524 zero-fluoroscopy catheter ablation procedures performed between January 2006 and October 2013.
  • Exclusive use of the Ensite 3D mapping system (NavX and Velocity modes).
  • Transesophageal echocardiography (TEE) utilized for left-sided arrhythmias to assist with transseptal puncture.

Main Results:

  • No complications were reported in 524 procedures.
  • Fluoroscopy was rarely required (25 patients, mostly for concurrent procedures).
  • A single instance of unexpected fluoroscopy use occurred.

Conclusions:

  • 3D mapping systems enable the elimination of fluoroscopy in nearly all routine ablation procedures.
  • The safety and efficacy of zero-fluoroscopy ablation are demonstrated.
  • Technological advancements support the shift of ablation procedures beyond traditional catheterization labs.
