ABSTRACT
BACKGROUND:
Limited data are available regarding myocardial injury and its risk factors in percutaneous coronary interventions (PCI) of severe calcified lesions using orbital atherectomy (OA).METHODS:
Patients who underwent OA at our institution were retrospectively enrolled into the present registry. High-sensitive Troponin I (hsTroponin I), EKG and echocardiography were used to assess myocardial injury after the procedure.RESULTS:
A total of 27 patients between who underwent OA between January 2022 and June 2023 were included. Myocardial injury (elevation of hsTroponin I above the 99th percentile upper reference limit) occurred in all patients. Median hsTroponin I on the first day after the procedure was 1093 (557-4037) ng/l with a minimum of 86 ng/l and a maximum of 25,756 ng/l. Myocardial infarction occurred in two patients (7 %), who had severe coronary dissection after OA. Lesions were longer (47 [38-52] mm vs. 20 [14-47] mm; p = 0.009) in patients with hsTroponin I levels above the median compared to those with levels below. Furthermore, a moderate correlation between hsTroponin I and lesion length was detected (r = 0.54; p = 0.004).CONCLUSIONS:
In the present study myocardial injury occurred in all patients after OA without loss of viable myocardium in the majority of patients. Lesions length was found to be a significant factor associated with markedly increased hsTroponin I after the OA procedure.Palavras-chave
