Ascending aorta and aortic arch replacement combined with antegrade stent grafting of the descending thoracic aorta represents an emerging hybrid surgical approach for complex and extensive thoracic aortic disease. We present a case of a patient at low risk for spinal cord ischemia who underwent hybrid thoracic aortic surgery (aortic arch replacement and E-vita prosthesis implantation) and developed a spinal cord injury (SCI) after the intervention. Treatment aimed at increasing spinal cord perfusion pressure with the aid of cerebrospinal fluid (CSF) drainage was effective in recovering neuromuscular function.

This study assessed the clinical utility of near-infrared fluorescence imaging using indocyanine green in off-pump beating heart total endoscopic and robotic-assisted coronary artery bypass using the fluorescence imaging system for the da Vinci Si on a canine model for vessel identification, graft patency, and correlation of graft patency with ultrasound transit-time flow measurement probe. ⋯ Use of near-infrared fluorescence with indocyanine green was feasible in our study, and would be of great benefit during total endoscopic robotic-assisted coronary artery bypass using the fluorescence imaging-capable da Vinci Si system to help identify the internal mammary artery, delineate the coronary anatomy, and also determine patency of the anastomoses. This procedure correlated well with transit-time flow measurement.

Comparative Study
The role of the minimally invasive beating heart technique in reoperative valve surgery.
We reviewed our experience to assess potential advantages of minimally invasive surgery without aortic clamping over conventional median sternotomy and cardioplegic arrest during reoperative valve surgery. ⋯ Redo valve surgery with an unclamped aorta is feasible, effective, and at least as safe as surgery using cardioplegic arrest. There was, however, no difference in biochemical or clinical outcomes from conventional surgery using aortic clamping and cardioplegic techniques.

This study assesses surgical procedures, operative outcome, and early and intermediate-term results of infective valve endocarditis in children with congenital heart disease. ⋯ Mitral and tricuspid valve repairs can be performed with low morbidity/mortality rates and satisfactory intermediate-term results in children with infective valve endocarditis.

Cardiac surgical patients with postoperative complications frequently require prolonged intensive care yet survive to hospital discharge. ⋯ Although cardiac surgery patients with major postoperative complications frequently survive to hospital discharge, survival after discharge is significantly reduced in patients requiring prolonged ICU care. Reduced survival in patients with a high risk of complications and anticipated long ICU stays should be considered when discussing surgical versus nonsurgical options.
