Study Overview
Brief Summary
The study aims to evaluate the decision-making pathways of interventional cardiologists, when assessing patients, presented with stable coronary artery disease.
Detailed Description
2nd International Survey on Interventional Strategies is a web-based platform.
The survey contains specific questions and dedicated case presentations on two major topics.
The first part queries the characteristics of the participants, including overall experience in interventional cardiology, annual volume of percutaneous coronary intervention (PCI), and duration of experience with quantitative coronary angiography (QCA), intravascular ultrasound (IVUS),optical coherence tomography (OCT), fractional flow reserve (FFR) and non-hyperaemic pressure ratios (NHPR). The survey uses here predefined categories and single-choice questions.
The second part investigates personal strategies for evaluating angiographically intermediate stenoses in the catheterization laboratory. Here, participants are asked to evaluate 5 complete coronary angiograms. All cases are characterised as stable angina without relevant changes on resting ECG. No information about non-invasive testing is known or provided.
Here participants are asked to (1) localise all relevant stenoses by indicating the involved segment; (2) define percent diameter stenosis (%DS) by visual estimate; and (3) determine the significance of the stenosis of interest. In cases of angiographic uncertainty, the preferred diagnostic tool is asked to be selected from the arsenal available in the catheterisation laboratory, namely QCA, IVUS, OCT, FFR or NHPR. Participants are asked to make their decisions assuming ideal world conditions, without considering any financial restrictions or local regulations, but only after the best clinical practice achievable in this virtual catheterisation laboratory.
