Comparing the effects of rotational atherectomy and conventional stenting on coronary microcirculation

Impact of Rotational Atherectomy on Coronary Microvascular Function in Patients With Stable Angina and Calcified Coronary Artery Disease

Not applicable Interventional Lithuanian University of Health Sciences · NCT05771961

This study is testing whether a special heart procedure called rotational atherectomy works better than regular stenting for improving blood flow in the tiny vessels of the heart for people with blocked arteries and stable heart disease.

What this trial studies

This observational study aims to compare the effects of rotational atherectomy and conventional stenting on coronary microcirculation in patients with calcified coronary artery lesions and stable coronary artery disease (CAD). Patients will undergo serial invasive and non-invasive microvascular testing before and after the interventions to assess the prevalence of coronary microvascular dysfunction. The study will provide insights into how each procedure impacts blood flow in the smallest vessels of the heart, which is crucial for overall cardiac health.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with stable coronary artery calcified lesions requiring percutaneous coronary intervention.

Not a fit: Patients with a history of myocardial infarction, CABG, or those with significant comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with stable CAD, enhancing their heart health and quality of life.

How similar studies have performed: While the approach of comparing these two interventions is not widely tested, previous studies have indicated potential benefits of rotational atherectomy in similar patient populations.
