Intraoperative Versus Postoperative Hydroxocobalamin for Vasoplegic Shock in Cardiothoracic Surgery.
Hydroxocobalamin inhibits nitric oxide pathways contributing to vasoplegic shock in patients undergoing cardiopulmonary bypass (CPB). The objective of this study was to evaluate the effect of intraoperative versus postoperative application of hydroxocobalamin for vasoplegic shock in patients undergoing CPB. ⋯ A difference in vasopressor-free days after CPB was not found between patients who received hydroxocobalamin intraoperatively versus postoperatively for vasoplegic shock.

Case ReportsDiastolic Left Main Coronary Artery Flow Reversal.
In patients undergoing percutaneous cardiac interventions, perioperative transesophageal echocardiography is used routinely, often revealing an unusual pathology that was not previously detected with transthoracic echocardiography. In this e-challenge, the authors present a patient undergoing percutaneous transcatheter aortic valve replacement, with preprocedural transesophageal echocardiography revealing an abnormal color Doppler signal near the left main coronary artery during diastole.
