Avoiding sternotomy in repeat coronary artery bypass grafting: Feasibility, safety, and mid-term outcome of the transabdominal off-pump technique using the right gastroepiploic artery.
Repeat sternotomy is associated with a substantial risk of cardiovascular injury. We evaluated the feasibility and clinical outcome of a transabdominal approach without sternotomy and without cardiopulmonary bypass in repeat coronary artery bypass grafting, using the right gastroepiploic artery to graft vessels of the inferior wall of the heart. ⋯ Transabdominal off-pump coronary artery bypass grafting using the right gastroepiploic artery is a safe and effective procedure with low in-hospital mortality and morbidity and favorable mid-term outcome. In redo operations, this technique excludes the risk of cardiovascular injury.

Optimization of mediastinal staging in potential candidates for stereotactic radiosurgery of the chest.
Patients with medically inoperable nonsmall-cell lung cancer generally have limited staging of the mediastinum using computed tomography and combined positron emission tomography and computed tomography, before stereotactic radiosurgery. Historical data have demonstrated the superiority of tissue sampling techniques such as endobronchial ultrasonography and mediastinoscopy compared with imaging studies in accurately determining the nodal stage. We believe, that at a minimum, mediastinal interrogation with endobronchial ultrasonography should be performed before patients undergo stereotactic radiosurgery. ⋯ Endobronchial ultrasonography-transbronchial needle aspirates is more accurate than computed tomography and positron emission tomography in staging the mediastinum, can be performed with minimal morbidity, and should be considered for all patients considered candidates for stereotactic radiosurgery.

Risk of recurrent gastrointestinal bleeding after aortic valve replacement in patients with Heyde syndrome.
We sought to evaluate the effectiveness of aortic valve replacement for reducing gastrointestinal bleeding in patients with Heyde syndrome, in whom gastrointestinal bleeding is associated with intestinal angiodysplasia and aortic valve stenosis. ⋯ Aortic valve replacement seems to decrease the risk of gastrointestinal bleeding in patients with Heyde syndrome and is curative in approximately 80%. Although rates of recurrent bleeding were not significantly different between the 2 prosthetic valve types, the higher risk of bleeding in patients receiving warfarin makes bioprosthetic valves the valve of choice for most patients.
