Teaching Concepts of Transesophageal Echocardiography via Web-based Modules.
Teaching transesophageal echocardiography (TEE) remains challenging. The authors hypothesized that using online modules with live teaching in an echo training course would be feasible and result in superior knowledge acquisition to live teaching only. ⋯ A multimodal TEE curriculum increased trainees' knowledge of TEE concepts and had a positive reception from trainees.

Dexmedetomidine Does Not Reduce Atrial Fibrillation After Lung Cancer Surgery.
To evaluate whether the use of intraoperative dexmedetomidine (DEX) during lung cancer surgery may reduce the incidence of postoperative atrial fibrillation (POAF). ⋯ These results were similar to those published elsewhere on POAF incidence and risk factors. This study could not confirm the hypothesis that the intraoperative use of DEX is associated with a reduced rate of POAF after thoracic surgery for lung cancer.

Elevated Arterial Lactate Concentrations Early After Coronary Artery Bypass Grafting Are Associated With Increased Anaerobic Metabolism in Skeletal Muscle.
To assess the effect of coronary artery bypass grafting with cardiopulmonary bypass on muscle perfusion, oxygen extraction, and lactate release during postoperative rest and exercise. ⋯ The patients had elevated anaerobic metabolism in skeletal muscle after surgery to compensate for anemia. Lactate was released from the leg into the general circulation during postoperative rest and exercise. The postoperatively reduced hemoglobin concentration of 11.4 mg/dL (10.6-12.3) resulted in increased anaerobic metabolism and release of lactate from skeletal muscle. The authors concluded that coronary artery bypass grafting patients are susceptible to anaerobic metabolism even with maintained peripheral blood flow.

Complications of Catheter-Based Electrophysiology Procedures in Adults with Congenital Heart Disease: A National Analysis.
To determine whether adult congenital heart disease patients (ACHD) undergoing catheter-based electrophysiology (EP) procedures have an increased risk for complications compared with adults without congenital heart disease. ⋯ ACHD patients experienced greater morbidity after catheter-based EP procedures. This finding will be of increasing significance as ACHD patients occupy a growing segment of the population undergoing these procedures. Further investigations are warranted to determine whether this increased risk is modifiable, with the aim of improving patient safety.
