Insights

High-volume operators performing percutaneous coronary interventions (PCI) for chronic total occlusion (CTO) achieve better procedural success and fewer complications. Performing at least 40 CTO cases annually is linked to optimal outcomes.

Area of Science:

  • Interventional Cardiology
  • Vascular Surgery
  • Health Services Research

Background:

  • Low operator and institutional volume negatively impacts percutaneous coronary interventions (PCI) outcomes.
  • This association is particularly critical for complex procedures like chronic total occlusion (CTO) interventions.

Purpose of the Study:

  • To investigate the relationship between operator volume and procedural success in PCI for CTO.
  • To identify optimal operator caseloads for improved patient outcomes in CTO interventions.

Main Methods:

  • Analysis of 14,899 CTO-PCI cases from the ORPKI national registry (2014-2020).
  • Primary endpoint: procedural success (TIMI II/III flow, no in-hospital death/MI).
  • Secondary endpoints: periprocedural complications.

Main Results:

  • Overall procedural success rate was 66.1%.
  • A direct correlation exists between annual operator volume and procedural success (OR: 1.006).
  • Operators performing ≥40 CTO cases/year demonstrated superior technical success and lower complication rates (e.g., coronary artery perforation).

Conclusions:

  • High-volume operators performing CTO-PCI achieve significantly better procedural success rates.
  • Increased annual caseloads for CTO interventions correlate with improved overall quality and reduced periprocedural complications.

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...
