Survival after surgery with cardiopulmonary bypass in low weight patients.
To evaluate risk factors for hospital death in patients weighing < 2.5 kg undergoing open-heart surgery, records of 34 consecutive low-weight patients operated on between December 1997 and November 2004 were reviewed. Mean weight was 2.152 +/- 0.237 kg (range, 1.600 to 2.460 kg). Biventricular repair was achieved in 28 patients. ⋯ Hyperlactatemia at the end of cardiopulmonary bypass was also associated with poor survival. A Comprehensive Aristotle score < 19 was the strongest predictor of survival in low-weight patients undergoing open-heart surgery. Biventricular repair, when feasible, should be promoted to improve outcome.

Case ReportsChylous pericardial effusion after aortic valve replacement.
Chylous pericardial effusion after open-heart surgery is a rare complication. We report a case of chylous pericardial effusion following aortic valve replacement, which presented as cardiac tamponade, and its subsequent management.

Case ReportsHancock valve deterioration in tricuspid position for Ebstein's anomaly.
A 65-year-old woman with a Hancock valve implanted 25 years earlier for Ebstein's anomaly underwent a successful second tricuspid valve replacement with a Mosaic valve because of significant tricuspid regurgitation. At surgery, it was found that the Hancock valve had a cylinder-shaped hole and had lost its entire structure. Tricuspid valve dysfunction may be tolerated for a long time before surgery is contemplated.

Case ReportsMycotic pseudoaneurysm of the ascending aorta at site of aortic cannulation.
Reoperation for pseudoaneurysm of the ascending aorta presents a surgical challenge. Instituting femorofemoral bypass and establishing hypothermic circulatory arrest is a well-known strategy, although not free from complications. We report a case of mycotic pseudoaneurysm after coronary artery bypass in a 53-year-old man, at the site of previous aortic cannulation, and review the surgical strategies proposed to manage this pathologic entity.

Easy technique for placing anchoring sutures for aortic root reimplantation.
In the aortic valve-sparing reimplantation technique, insertion of the anchoring sutures beneath the valve is a crucial but difficult step because the spared aortic cusps obscure the field of view. We present a novel and easy method of placing these anchoring stitches with good exposure of the subvalvular tissue.
