Background: There are limited data about determinant factors of target lesion failure (TLF) in lesions after percutaneous coronary intervention (PCI) using a drug-coated balloon (DCB) for de novo coronary artery lesions, including optical coherence tomography (OCT) findings.
Aims: The present study aims to investigate the associated factors of TLF in de novo coronary artery lesions with DCB treatment.
Methods: We retrospectively enrolled 328 de novo coronary artery lesions in 328 patients who had undergone PCI with a DCB.
Purpose: The association between the extent of the wire and device bias as assessed by optical coherence tomography (OCT) in the healthy portion of the vessel and the risk of coronary artery injury after orbital atherectomy (OA) has not been fully elucidated. Thus, purpose of this study is to investigate the association between pre-OA OCT findings and post-OA coronary artery injury by OCT.
Methods: We enrolled 148 de novo lesions having calcified lesion required OA (max Ca angle > 90°) in 135 patients who underwent both pre- and post-OA OCT.
Article Synopsis
- * It involved 307 patients treated at 12 centers in Japan, finding that INR (a measure of blood clotting) levels were typically too low before and after the procedure, contributing to complications.
- * Despite the low levels of anticoagulation, major bleeding events occurred in 10% of patients, while serious thromboembolic events were not observed, suggesting a need for better management of anticoagulation in these patients.
Although the novel coronavirus disease 2019 (COVID-19) causes severe viral pneumonia, it has also been reported, in some cases, to co-exist with ST-segment elevation myocardial infarction. Here, we describe the case of a patient with COVID-19 and coronary risk factors for hypertension, including smoking and obesity, who developed acute myocardial infarction due to primary coronary artery thrombosis and was treated with transcatheter thrombus aspiration and percutaneous transluminal coronary recanalization (PTCR) with intracoronary urokinase administration. A large volume of thrombus was collected and thrombolysis in myocardial infarction flow grade 3 was obtained after the procedures.
