Impact of intraoperative transesophageal echocardiography in patients undergoing valve replacement.
The role of intraoperative transesophageal echocardiography (IOTEE) in valve replacement surgery is not well established. The aim of this study was to explore the impact of immediate postpump IOTEE in valve replacement surgery at a single tertiary medical center. ⋯ Immediate postpump IOTEE is an important diagnostic and therapeutic role in valve replacement surgery and should be widely implemented.

We aimed to identify risk factors for reexploration for bleeding after surgical revascularization in our practice. We also looked at the impact of resternotomy and the effect of time delay on mortality and other in-hospital outcomes. ⋯ Risk factors for reexploration for bleeding after coronary artery bypass grafting include older age, smaller body mass index, nonelective cases, and 5 or more distal anastomoses. Preoperative aspirin and heparin were risk factors for the on-pump coronary artery surgery group. Patients needing reexploration are at higher risk of complications if the time to reexploration is prolonged. Policies that promote early return to the operating theater for reexploration should be encouraged.

Postpneumonectomy syndrome is defined as an airway obstruction due to mediastinal shift and rotation after pneumonectomy. A patient who had undergone a left pneumonectomy for bronchial carcinoma 13 years before presented with tension pneumothorax of her remaining lung. ⋯ The goal of this operation was to reduce the right pleural cavity volume by implanting an intrapleural prosthesis in the pneumonectomy cavity. This treatment is identical to that used for postpneumonectomy syndrome, which allows the right lung to be rejoined with the thoracic wall.

Patients with double inlet left ventricle/l-transposition and similar morphologies have their systemic outflow traverse a bulboventricular foramen (BVF), which has a propensity to narrow over time. A Norwood procedure may be performed as the initial palliation. We prefer aortic arch repair and pulmonary artery banding, delaying Damus-Kaye-Stansel (DKS) or BVF resection until the second palliation. The aims of this study were to compare our results with those reported for Norwood strategy and examine the development of systemic outflow obstruction. ⋯ Our approach achieves low operative mortality and morbidity and compares favorably with reported results for Norwood palliation. The significant rate of systemic outflow obstruction in those who did not undergo DKS at the second stage confirms the utility of early DKS in children with this morphology.

We report the case of a fistula formation between the left circumflex coronary artery draining into the left atrium as a complication of radiofrequency cardio-ablation and resection of the atrial appendages. This complication was diagnosed with the use of transesophageal echocardiography and was subsequently confirmed on coronary angiography.
