Insights

For women with small radial arteries undergoing ad hoc percutaneous coronary intervention (PCI), a modified 6 French workflow using 5 French diagnostic catheters is more effective than a standard 6 French approach.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Access

Background:

  • Transradial percutaneous coronary intervention (PCI) offers advantages over transfemoral PCI.
  • A 6 French workflow is common for ad hoc PCI, potentially limiting options for patients with small radial arteries.

Purpose of the Study:

  • To compare a standard 6 French workflow with a modified 5 French diagnostic catheter workflow for ad hoc PCI in women under 160cm.

Main Methods:

  • 120 women (<160cm) were evaluated using either a full 6 French workflow or a modified workflow (6F sheath, 5F diagnostic catheters, 6F guiding catheter).
  • Outcomes measured included radial spasm, access site switch, and time to guidewire lesion crossing.

Main Results:

  • Radial spasm (43% vs 25%) and access site switch (11% vs 2%) were more frequent with the 6 French diagnostic catheters.
  • Time to guidewire lesion crossing was significantly longer with the 6 French diagnostic catheters (23±11min vs 16±7min).

Conclusions:

  • A modified workflow using a 6 French sheath, 5 French diagnostic catheters, and a 6 French guiding catheter is a more straightforward and effective strategy for ad hoc PCI in patients with anticipated unfavorable radial access.

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

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...
