Using a dynamic roadmap system to guide heart artery pressure measurements

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of a dynamic coronary roadmap system during coronary angiography in patients with significant coronary artery stenosis. It aims to improve the accuracy and efficiency of measuring fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) by utilizing advanced software to visualize the coronary anatomy. Patients with stable angina or acute coronary syndrome will be included, and the study will assess how the roadmap can enhance the procedural outcomes compared to traditional methods. The goal is to determine if this innovative approach can streamline the evaluation process and improve patient management.

2. Patients with stable angina, including asymptomatic ischemic heart disease, who have 50-90% stenosis of the causative vessel by coronary angiography
3. Acute coronary syndrome patients with multivessel disease and 50-90% stenosis of non-caused vessels that did not cause acute coronary syndrome
4. Patients who voluntarily decided to participate in this study and gave written consent to the subject consent form

Exclusion Criteria:
