Primary percutaneous coronary intervention of anomalous origin of a high take-off of right coronary artery arising from ascending aorta with percutaneous cardiopulmonary support in acute myocardial infarction.

Coronary angiography of high take-off right coronary artery (RCA) arising from ascending aorta under percutaneous cardiopulmonary support may be more effective at the site distal to RCA ostium rather than proximal. Guide extension catheters (GECs) may be useful to strengthen backup of percutaneous coronary interventions (PCI) system and to contrast coronary lesions clearly during PCI of these RCAs.

Nine-year trend of oral anticoagulant use in patients with embolic stroke due to nonvalvular atrial fibrillation.

Background: Direct oral anticoagulants (DOACs) are increasingly used as an alternative to warfarin in patients with nonvalvular atrial fibrillation (NVAF). However, whether there is sufficient prescription of oral anticoagulants (OACs) to decrease the incidence of embolic stroke remains unclear.

Methods And Results: We conducted a retrospective observational study of patients hospitalized with ischemic stroke between January 1, 2010 and December 31, 2018.
