Left and codominant coronary artery circulations are associated with higher in-hospital mortality among patients undergoing percutaneous coronary intervention for acute coronary syndromes: report From the National Cardiovascular Database Cath Percutaneous Coronary Intervention (CathPCI) Registry.
Left or codominant coronary arterial circulation may represent less well-balanced myocardial perfusion and thus confer worse prognosis in acute coronary syndrome, especially for culprit lesions arising from the left coronary artery. ⋯ Left and codominance are associated with modestly increased post-percutaneous coronary intervention in-hospital mortality in patients with acute coronary syndrome. Confirmation of these findings with angiographic core laboratory verification of coronary dominance and longer term follow-up will be desirable.

ReviewHow small is too small? A systematic review of center volume and outcome after cardiac transplantation.
The aim of this study was to assess the relationship between the volume of cardiac transplantation procedures performed in a center and the outcome after cardiac transplantation. ⋯ There is a relationship between center volume and mortality in heart transplantation. The existence of a minimum acceptable center volume or threshold is unproven. However, a level of 10 to 12 heart transplants per year corresponds to the upper limit of low-volume categories that may have relatively higher mortality. It is not known whether outcomes for patients treated in low-volume transplant centers would be improved by reorganizing centers to ensure volumes in excess of 10 to 12 heart transplants per year.
