Valve replacement in high-risk patients with severe aortic stenosis has undergone a huge paradigm shift in the recent years in terms of procedural details and vascular access site for patients who have poor peripheral access. Carotid artery is one of the more promising access sites which has been proven to provide a good alternative site with comparable outcomes to transfemoral approach. In this manuscript, we will provide a review of the current literature on transaortic, transapical, transaxillary and transcarotid approaches to transcatheter aortic valve replacement (TAVR) while focusing on the transcarotid approach.

Utilization of direct oral anticoagulants (DOAC) have steadily increased since their approval and are now recommended over warfarin for both stroke prevention in nonvalvular atrial fibrillation and treatment of venous thromboembolism (VTE). With increased DOAC use, the number of major bleeding events requiring medical intervention will continue to rise. Until 2015, warfarin maintained an advantage as the only oral anticoagulant with a specific reversal agent. ⋯ Due to the manufacturing practices required to yield these reversal therapies, they are available at high cost to hospital systems and as a result, have been met with resistance. Data exists describing both prothrombin complex concentrates (PCC) and andexanet alfa for DOAC reversal, however, without head-to-head comparison. Until future studies are available, current literature must be critically evaluated to aid in the clinical decision-making process of how to treat patients with life-threatening DOAC-related bleeding.

Out-of-hospital cardiac arrest (OHCA) is the leading cause of death in the United States, as 90% of them are fatal per the 2018 American Heart Association statistics. As many as fifty-percent of cardiac arrest events display an initial rhythm of pulseless ventricular tachycardia (pVT) and ventricular fibrillation (VF), and of those, coronary artery disease (CAD) is found in 60-80% of patients. ⋯ The Coronary Angiography after Cardiac Arrest (COACT) trial was designed to compare survival between an immediate or delayed coronary angiography strategy in non-STEMI (NSTEMI) OHCA patients, following successful resuscitation. We present a systematic review of the history of management strategies in OHCA and propose guidelines to manage such patients in light of the COACT trial.
