Comparative StudyOff-pump coronary artery surgery in the elderly.
We compared the results of off-pump (n = 186) and on-pump (n = 389) coronary artery bypass grafting in elderly patients over 70 years old. Patients undergoing single-vessel revascularization were excluded from the study. ⋯ The off-pump group fared better in intubation time (16 +/- 4 hours versus 25 +/- 5 hours), blood loss (365 +/- 58 mL versus 584 +/- 72 mL), the need for blood transfusion (31.7% versus 44%), reoperation for bleeding (0.5% versus 3.6%), atrial fibrillation (10.2% versus 18.5%), intensive care unit stay (21 +/- 8 hours versus 34 +/- 10 hours), and total hospital stay (5 +/- 2 days versus 8 +/- 3 days). Off-pump bypass surgery is thus safe for elderly patients and is associated with reduced morbidity and shorter hospitalization than on-pump surgery.

Randomized Controlled Trial Clinical TrialEffects of intravenous triiodothyronine during coronary artery bypass surgery.
A prospective randomized and double-blind study was performed to evaluate whether perioperative triiodothyronine administration has any effect on cardiovascular performance after coronary artery bypass surgery. Sixty patients were assigned to 2 groups of 30 each. When crossclamping ended, group A received an intravenous bolus of triiodothyronine, followed by infusion for 6 hours. ⋯ No significant differences were detected between the groups in the incidence of arrhythmia, the need for inotropic support, intensive care unit stay, mortality, and morbidity. Perioperative administration of triiodothyronine increased cardiac output slightly and decreased systemic vascular resistance, but it had no effect on operative outcome. Routine use after coronary surgery is thus not recommended.

Case ReportsRetroesophageal hematoma caused by fish bone perforation of the esophagus.
A 39-year-old man complained of acute dysphagia and dorsal pain while eating fish. Radiologic and endoscopic studies revealed a retroesophageal mass, which was later shown to be a hematoma.

Total reconstruction of the mitral valve with autopericardium: anatomical study.
Mitral valve repair has several advantages over prosthetic valve replacement. A new technique of total reconstruction of the mitral valve with autologous pericardium is described. The native mitral valve leaflets and chordae were excised from 10 human cadaver hearts, in the same way as for prosthetic valve replacement. ⋯ The new valve was fashioned and inserted in the native valve position. Hydraulic probes showed good competence in all 10 reconstructed mitral valves. This method might be a good alternative to prosthetic valve replacement.
