Insights

The Tiger catheter significantly reduced contrast volume and procedure time during transradial coronary angiography compared to Judkins and Jacky catheters. This study highlights the Tiger catheter

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • The transradial approach is standard for coronary angiography.
  • Limited research compares Tiger, Jacky, and Judkins catheters for transradial coronary angiography.
  • This study evaluates three common catheter strategies.

Purpose of the Study:

  • To compare the procedural performance of Tiger, Jacky, and Judkins catheters in transradial coronary angiography.
  • To assess differences in procedure time, contrast volume, and fluoroscopy time.

Main Methods:

  • A single-center, randomized trial allocated 99 patients 1:1:1 to Tiger (T), Jacky (JA), or Judkins (JU) initial strategies.
  • Elective right transradial coronary angiography was performed by experienced operators.
  • Primary endpoints were procedure time, contrast volume, and fluoroscopy time.

Main Results:

  • The Tiger group used significantly less contrast volume (40ml) than JA (50ml) and JU (55ml) groups (P=0.04).
  • Total procedural time was significantly lower in the Tiger group (9.2 min) compared to JA (11.92 min) and JU (12.8 min) groups (P=0.003).
  • No significant difference in fluoroscopy time was observed between the groups (P=0.08).

Conclusions:

  • The Tiger catheter demonstrates superior procedural efficiency in terms of reduced contrast volume and procedure time for transradial coronary angiography.
  • Catheter choice impacts procedural outcomes, suggesting potential for optimization with the Tiger catheter.
  • Further research may explore broader adoption of the Tiger catheter in clinical practice.

Cardiac Catheterization I: Pre-Procedure Overview

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 V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
