Coronary artery anomalies arising from the pulmonary artery are rare, result in reversed flow in the affected coronary artery, and are commonly associated with myocardial ischemia in infancy or childhood. Uncorrected survival to adult age is rare. We present a 77-year-old individual with anomalous right coronary artery from the pulmonary artery (ARCAPA), diagnosed by coronary angiography, whose clinical presentation was governed by coexisting obstructive atherosclerotic coronary disease.

Comparison of Outcomes Between Low-Risk Aortic Valve Replacement Trials and a Surgical Registry.
JAMA Netw Open

Division of Cardiothoracic and Vascular Surgery, Columbia University Irving Medical Center, New York, New York.
Importance: It remains unknown whether outcomes of the Placement of Aortic Transcatheter Valves 3 (PARTNER 3) and Evolut Low Risk trials are comparable with surgical outcomes in nontrial settings, considering the added risk of concomitant cardiac operations.
Objective: To compare 30-day mortality and stroke incidences of patients in the surgical aortic valve replacement (SAVR) arm of low-risk trials with those of similar patients in the US Society of Thoracic Surgeons Adult Cardiac Surgery Database (STS ACSD).
Design, Setting, And Participants: A cross-sectional sampling study was conducted of adults in the STS ACSD with severe aortic stenosis at low surgical risk for AVR who underwent SAVR during the years low-risk AVR trials (PARTNER 3 and Evolut Low Risk) were enrolling (calendar years 2016-2018).

Type I and mixed cryoglobulinemic vasculitis differ in pathophysiology, clinical presentation, and therapeutic response. We report a case of refractory cryoglobulinemic vasculitis diagnosed following ischemic non-obstructive coronary artery disease (INOCA). The patient presented with dyspnea, as well as abdominal pain due to ischemic enteritis, purpura, and renal failure requiring dialysis.

Background: Coronary air embolism is a rare but severe complication of coronary interventions.
Case Presentation: We present a case of a massive air embolism in the right coronary artery during percutaneous coronary intervention, resulting in ventricular fibrillation. The patient was successfully resuscitated with electric defibrillation, leading to full recovery and TIMI 3 coronary flow.

Cangrelor Use for Viabahn Stent Graft Patency as Bridge to Coronary Artery Bypass Graft Surgery.
J Pharm Pract

Department of Cardiothoracic Surgery, Jefferson Health Abington Hospital, Abington, PA, USA.
Utilization of cangrelor following coronary artery stent placement as a bridge to cardiac surgery has been previously described in the literature. However, the use of cangrelor as bridge therapy to cardiac surgery for endovascular revascularization is lacking. We describe a case involving a 47-year-old female who developed a left lower extremity tibioperoneal trunk non-obstructing arterial dissection following extracorporeal membrane oxygenation decannulation, requiring repair with a Viabahn endoprosthesis.
