Rare Sequela of Spontaneous Coronary Artery Dissection.

Non-atherosclerotic spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome. Here, we report a case of acute ischemic mitral regurgitation (MR) due to SCAD of the left main coronary artery. Given the extent of the acute ischemic MR and multi-vessel disease, the decision was made to pursue coronary artery bypass graft surgery and annuloplasty mitral valve ring repair.

Multi-Vessel Coronary Artery Ectasia.

Coronary artery ectasia is a relatively rare entity, especially when it involves the left main coronary artery. Furthermore, it is even more uncommon for such a disease process to involve multiple coronary arteries. Here we describe a case of a 78-year-old female who did not possess any of the common risk factors or vasculitic etiologies associated with coronary artery ectasia, who was found to have multi-vessel ectatic segments, including that of the left main coronary artery. This case illuminates the difficult decision making regarding stenting of the coronary arteries with ectatic segments and the decision to anticoagulate.

Extensive Coronary Thrombosis as a Sequelae of COVID-19 Presenting as a STEMI.

Thrombotic complications, in particular ST-elevation myocardial infarction (STEMI), have been described in active Coronavirus disease 2019 (COVID-19) cases. This is a result of systemic inflammation that often leads to endothelial activation, microvascular thrombosis and a hypercoagulable state. However, it is unknown how long patients who have cleared the COVID-19 infection remain at risk for coronary thrombosis as a sequela of disease burden. We present a case of a patient who presented three to four weeks following the initial infection.
