Background: A small number of female cardiologists work in the field of interventional cardiology. Such disparity is observed in most European countries.
Aims: We present the first national report on the practice patterns and outcomes regarding percutaneous coronary interventions (PCIs) performed by female operators (FOs) in Poland.
Methods: Data were collected from the National Registry of Invasive Cardiology Procedures (Ogólnopolski Rejestr Procedur Kardiologii Inwazyjnej [ORPKI]) between January 2014 and December 2017.
Results: A total of 31 FOs (4.1%) performed 12 935 PCIs (2.8%). The median (interquartile range [IQR]) number of PCIs performed by FOs per year was 75 (43-154), whereas that by male operators was 139 (67-216; P <0.01). Patients handled by FOs were characterized by a lower prevalence of cardiovascular risk factors and previous coronary artery interventions. Acute coronary syndrome was the main indication for treatment (74.66%). Compared with male operators, FOs handled significantly more patients with single‑vessel disease (87.02% vs 84.72%; P <0.001). They used smaller contrast doses during PCIs (median [IQR], 170.36 [77.54] cm3 vs 173.48 [77.54] cm3; P <0.001) yet higher doses of radiation exposure (median [IQR], 843 [472-1409] mGy vs 815 [458-1390] mGy; P = 0.01). There was no difference in clinical outcomes (a composite of all‑cause death, bleeding at the puncture site, or coronary artery perforation) associated with the operator's sex.
Conclusions: Women represent a minority of operators in interventional cardiology and are responsible for a low percentage of PCIs. Nonetheless, the practice patterns and outcomes of PCIs performed by FOs are similar to those of male operators.
