Evaluating the impact of calcification on coronary artery procedures

Characteristics of Calcification in a Chronic Total Occlusion on Computed Tomography Coronary Angiogram and Percutaneous Coronary Intervention Outcomes- a Single Centre Observational Study

Observational Sandwell & West Birmingham Hospitals NHS Trust · NCT06414551

This study looks at how the amount and type of calcium buildup in heart arteries affects the success of a specific heart procedure in patients with blocked arteries.

What this trial studies

This observational study aims to assess the relationship between calcification characteristics identified through Computed Tomography Coronary Angiography (CTCA) and the outcomes of Percutaneous Coronary Intervention (PCI) in patients with Chronic Total Occlusion (CTO) of the coronary artery. The study will retrospectively analyze data from patients who underwent both CTO PCI attempts and CTCA at the Sandwell and West Birmingham NHS Trust over the past five years. Key factors such as the site, density, and quantity of calcification will be correlated with PCI success and failure rates, utilizing statistical methods for analysis.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have undergone a CTO PCI attempt and a CTCA within the last five years.

Not a fit: Patients who are under 18 years old or who did not undergo a CTCA will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of how calcification affects PCI outcomes, potentially leading to improved treatment strategies for patients with CTO.

How similar studies have performed: Other studies have shown success in correlating imaging characteristics with procedural outcomes, suggesting that this approach is promising.
