Case ReportsPatent foramen ovale causing refractory hypoxemia after off-pump coronary artery bypass: a case report.
Patent foramen ovale (PFO) is not uncommon in the adult population undergoing cardiac surgery. Although usually innocent, PFO can cause severe hypoxemia, which can be reversed only by surgical or interventional interruption of the interatrial right-to-left shunt. Such a case is presented, and the diagnosis and pathophysiology are discussed.

A "fast track" approach to cardiac surgery can be defined as a perioperative process involving rapid progress from preoperative preparation through surgery and discharge from the hospital. Although highly individualized among the various heart surgery centers, the fast-track process is a team activity. ⋯ The necessary elements of the fast-track program are choice and the titration of short-acting anesthetic drugs, standardized surgical procedures, early extubation, rewarming and sustained postoperative normothermia, postoperative pain control, early ambulation, alimentation and discharge, and follow-up after discharge. We review the current approaches to some of these aspects of patient care.

Midterm results of routine bilateral internal thoracic artery grafting.
Skeletonized dissection of the internal thoracic artery (ITA) decreases the occurrence of sternal devascularization, thus decreasing the risk of postoperative sternal complications in patients undergoing bilateral ITA grafting. ⋯ Bilateral skeletonized ITA grafting is associated with satisfactory early and midterm results. We do not recommend the use of this surgical technique in patients with chronic obstructive pulmonary disease.

Off-pump coronary artery bypass grafting attenuates postoperative bleeding associated with preoperative clopidogrel administration.
Clopidogrel is being increasingly administered as primary therapy for acute coronary syndromes and prior to planned percutaneous coronary intervention (PCI). In these settings, surgical revascularization results in signifi- cantly increased postoperative bleeding, transfusion, and reexploration. Off-pump coronary artery bypass grafting (OPCAB) may decrease the extent of postoperative bleeding in patients exposed to clopidogrel. ⋯ Among these 15 OPCAB patients with immediately preoperative administration of clopidogrel and aspirin, outcome was improved compared with published results for on-pump coronary bypass patients and was equivalent to results among OPCAB patients not exposed to clopidogrel. Published, recommended approaches to clopidogrel administration, such as avoidance of pre-PCI clopidogrel, delay of surgery, and platelet transfusion do not appear to be necessary with OPCAB.

Improving neurologic outcome in off-pump surgery: the "no touch" technique.
As patients referred for cardiac surgery include increasingly older individuals, the prevalence of comorbid factors, such as previous cerebrovascular disease, carotid disease, aortic atherosclerosis, and reoperations, is on the rise. Avoiding manipulation of the ascending aorta in this high-risk subgroup may become a necessity to perform safe coronary artery bypass grafting (CABG) surgery. ⋯ Avoiding aortic manipulations in patients with severe atherosclerosis of the aorta, carotid disease, and a previous history of cerebrovascular accidents is technically feasible and is associated with a low risk of mortality and good shortterm results. Adopting this practice may reduce the incidence of stroke and improve early outcome in this subset of patients.
