An interventional lung assist membrane ventilator (iLA) for arteriovenous extracorporeal CO2 removal was connected to a small-diameter femoral artery by use of a chimney graft in an underweight patient with acute respiratory failure and a previous history of heart-lung transplantation. This concept offers additional therapeutic options in underweight patients requiring extracorporeal CO2 removal with arterial vessels that are too small for percutaneous arterial cannulation with standard-sized percutaneous insertable iLA cannulae.

Randomized Controlled Trial Comparative Study
The myocardial protective effects of a moderate-potassium blood cardioplegia in pediatric cardiac surgery: a randomized controlled trial.
We investigated the myocardial protective effect of a moderate-potassium cold blood cardioplegic solution (K+, 10 mmol/L) in pediatric cardiac surgery. ⋯ The present study demonstrated that the M (10 mmol/L) cold blood cardioplegia formula is associated with better myocardial protective effects when compared with conventional HP cardioplegia in pediatric patients.

Comparative Study
Valve-sparing root reconstruction does not compromise survival in acute type A aortic dissection.
The optimal management of the dissected aortic root remains unclear. The purpose of this study was to determine whether aortic valve-sparing root replacement (VSRR) compromises survival in aortic dissection repair and to evaluate the comparative efficacy of 2 types of VSRR procedures. ⋯ Both the David and Yacoub techniques have similar midterm durability in AAAD repair. When compared with the Bentall procedure, neither technique compromises short-term or midterm survival after AAAD repair.

Comparative Study
Aortic valve reconstruction of unicuspid aortic valve by tricuspidization using autologous pericardium.
Unicuspid aortic valve is a rare anatomic variant, but patients may require intervention for severe valve dysfunction at a young age. We introduce a new reconstructive technique for diseased unicuspid valve by tricuspidization with glutaraldehyde-treated autologous pericardium. ⋯ Diseased unicuspid aortic valves were treated by our original aortic valve reconstruction technique with excellent early results. We continue to study the long-term results.

Comparative Study
Postoperative assessment of laryngopharyngeal dysfunction in neonates after Norwood operation.
The purpose of this study was to evaluate the incidence of vocal cord (VC) and swallowing dysfunction in infants after the Norwood operation and to examine the relationship between laryngopharyngeal dysfunction and postoperative outcomes. ⋯ Vocal cord and swallowing dysfunction are common in infants after the Norwood operation and may increase the need for tube feeding regimens. Modification of surgical techniques for dissection and mobilization of the aorta can significantly reduce the incidence of these adverse outcomes.
