In patients with moyamoya syndrome requiring heart surgery, the brain blood flow during the low perfusion state under cardiopulmonary bypass is a concern. We report on a successful mitral valve repair and tricuspid repair in a patient with moyamoya syndrome, performed using an integrated cerebral protection strategy with cerebral oxygen saturation monitoring, intraaortic balloon pumping, and cardiopulmonary bypass perfusion at a relatively high pressure. An integrated approach with a thorough discussion among cardiac surgeons, anesthesiologists, and perfusionists was invaluable to protect brain perfusion in a patient with moyamoya syndrome.

In 2007 we began a hybrid program for hypoplastic left heart syndrome (HLHS) variants to potentially improve outcome in high-risk patients. During implementation we offered both hybrid and Norwood approaches to all risk categories. The purpose of this study was to perform a comparative analysis of intermediate survival. ⋯ While a risk-stratified approach for HLHS variant patients with selective use of hybrid palliation resulted in acceptable stage I mortality, the longer term mortality for high-risk patients remains higher than for standard risk regardless of treatment modality. Intrinsic patient risk factors (rather than treatment modality) likely determine long-term outcome in experienced centers. Our current high-risk approach has evolved to HPGE application with Norwood conversion whenever deemed medically possible.

We conducted a retrospective study to assess whether providing extracorporeal membrane oxygenation (ECMO) support to elderly patients (aged 70 years or more) who failed separation from cardiopulmonary bypass after cardiac surgery was a viable option. ⋯ Postcardiotomy ECMO support in elderly patients is associated with high postoperative morbidity and mortality. Nevertheless, it often provides the last line of therapy for these critically ill patients and may provide positive outcomes in selected subgroups.

Conflicting evidence currently exists regarding the causes and effects of delay of care in non-small cell lung cancer (NSCLC). We hypothesized that delayed surgery in early-stage NSCLC is associated with worse short-term and long-term outcomes. ⋯ Patients receiving delayed resection for clinical stage I NSCLC have higher comorbidity scores that may affect ability to perform lobectomy and result in higher perioperative mortality. However, delay in resection is independently associated with increased rates of upstaging and decreased median survival. Strategies to minimize delay while medically optimizing higher risk patients are needed.
