Recently, surgeons have embraced axillary artery cannulation for type A aortic dissection repair out of concern for malperfusion phenomena with traditional femoral artery cannulation. My colleagues and I sought to determine whether these concerns are justified. ⋯ Straight femoral cannulation for all phases of type A dissection repair is appropriate and yields excellent clinical results. The anticipated malperfusion events are actually rare (2 of 79 with femoral artery cannulation, or 2.5%).

Multicenter Study Comparative Study Clinical Trial Controlled Clinical Trial
Fenoldopam prophylaxis of postoperative acute renal failure in high-risk cardiac surgery patients.
Acute renal failure requiring replacement therapy occurs in 1% to 2% of patients who have undergone cardiac surgery with cardiopulmonary bypass and is associated with a very high mortality rate. The aim of this study was to determine if prophylactic treatment with fenoldopam mesylate of patients at high risk of postoperative acute renal failure reduced the incidence of this event. ⋯ Given the limitations of a nonrandomized prospective trial, our results support the hypothesis that fenoldopam may reduce the risk of acute renal failure in patients in whom endogenous and exogenous cathecolamines action may induce a renal vascular constrictive condition.

Left ventricular assist device performance with long-term circulatory support: lessons from the REMATCH trial.
Left ventricular assist device (LVAD) failure and malfunction rates are critical gauges for establishing LVADs as a long-term therapy for end-stage heart failure patients. These device performance measures, however, have been inadequately characterized in the bridge-to-transplantation literature. ⋯ Despite the observed rates of device malfunction and replacement, LVAD implantation confers clinically significant improvement with regard to survival as compared with medical management. Device modifications and innovations for infection management exhibit great promise of improving device performance in the near future.

Review Comparative Study
Factors affecting postoperative course and survival after en bloc resection for esophageal carcinoma.
To identify factors affecting postoperative course and survival after esophagectomy for cancer and reasons for improved survival over time. ⋯ Short-term outcome and survival of patients with resected esophageal cancer have improved over time. Advances in perioperative technique, staging methods, and surgical management combined with higher patient selection and use of neoadjuvant chemoradiation may be responsible for this progress.

Off-pump versus on-pump myocardial revascularization in low-risk patients with one or two vessel disease: perioperative results in a multicenter randomized controlled trial.
To evaluate hospital mortality and morbidity after myocardial revascularization in a prospective and multicenter study, comparing on-pump versus off-pump in a special subset of patients with lesions in the left descending artery, alone or associated with the right coronary artery. ⋯ We did not find any statistical difference in hospital mortality and morbidity using on-pump or off-pump techniques for low-risk patients.
