Outcome after pulmonary endarterectomy for segmental chronic thromboembolic pulmonary hypertension.
Determine the long-term outcome and need for additional therapy after pulmonary endarterectomy (PEA) for segmental chronic thromboembolic pulmonary hypertension. ⋯ PEA achieved excellent early and long-term results in segmental chronic thromboembolic pulmonary hypertension. However, patients with segmental disease are at increased risk of requiring additional therapy after PEA and should be carefully monitored.

Preoperative left atrial strain abnormalities are associated with the development of postoperative atrial fibrillation following isolated coronary artery bypass surgery.
Postoperative atrial fibrillation (POAF) is a common complication after coronary artery bypass grafting (CABG). Currently, there is no reliable way to determine preoperatively which patients will develop POAF following CABG. The aim of this study was to determine whether preoperative left atrial (LA) strain analysis might identify patients destined to develop POAF following CABG. ⋯ Decreased preoperative LA strain measurements, especially LA-fractional area change, LA-emptying fraction, and LA-reservoir strain, taken jointly, are more specific and sensitive than other preoperative parameters in identifying patients who will develop POAF following CABG. The ability to identify patients preoperatively who are destined to develop POAF following CABG provides a basis for limiting POAF prophylactic therapy to only those patients undergoing CABG who are most likely to benefit from it rather than to all patients undergoing CABG.

Priming protects the spinal cord in an experimental aortic occlusion model.
Paraplegia is a devastating complication in aortic aneurysm surgery. Modifying the spinal cord vasculature is a promising method in spinal cord protection. The aim of this study was to assess whether the spinal cord can be primed by occluding thoracic segmental arteries before simulated aneurysm repair in a porcine model. ⋯ Acute priming protects the spinal cord from ischemic injury in an experimental aortic crossclamp model.
