Acute respiratory distress syndrome (ARDS) is a life-threatening medical condition. Extracorporeal membrane oxygenation (ECMO) is a salvage therapy for patients with ARDS and refractory hypoxia. This study compared the characteristics and outcomes of ARDS patients who did or did not receive ECMO matched with Acute Physiology and Chronic Health Evaluation II (APACHE II) score and age. ⋯ Patients with ARDS who received ECMO treatment had higher inhospital survival rates than did those with a similar disease severity and at a similar age who did not receive ECMO.

One anatomic variant of pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals (PA/VSD/MAPCAs) is characterized by the absence of intrapericardial pulmonary arteries. This anatomy obviates the possibility of incorporating the pulmonary arteries for reconstruction or palliative procedures. The purpose of this study was to evaluate the surgical results in patients undergoing repair of PA/VSD/MAPCAs with absent pulmonary arteries. ⋯ The majority of patients with PA/VSD/MAPCAs and absent pulmonary arteries can undergo complete single-stage repair with satisfactory postoperative hemodynamics. These results suggest that unifocalization of MAPCAs can provide a reasonable pulmonary vascular bed in the absence of intrapericardial pulmonary arteries.

We sought to review current-era experience with multistage palliation of neonates with hypoplastic left heart syndrome (HLHS) and to examine the patients' anatomic, and surgical risk factors influencing outcomes. ⋯ This current single-institution experience demonstrates that patients' factors (ie, prematurity, low weight, genetic/extracardiac anomalies) continue to adversely affect survival. Conversely, surgical and perioperative management advances, along with the use of the right ventricle to pulmonary artery shunt, might have neutralized the effects of anatomic factors on survival. Technical imperfections requiring reoperations are associated with failure to progress through palliation stages and diminished survival.

Acquired cold urticaria is a condition characterized by the onset of pruritic hives, swelling, and occasional severe systemic reactions, during the rewarming phase, after cold exposure. Pulmonary thromboendarterectomy (PTE) is a cardiac surgical procedure where organized thrombus is excised from the pulmonary vasculature in order to improve pulmonary blood flow and relieve pressure on the right ventricle. A PTE requires institution of deep hypothermic circulatory arrest (DHCA) in order to reduce blood flow from collateral vessels during thrombus excision. We describe a case of PTE performed under DHCA in a patient with ACU.

Lung transplantation in patients older than 65 years is increasingly common, but questions remain regarding risk vs benefit and procedure choice. We identified short-term and long-term outcomes in older single-lung transplant (SLT) and bilateral-lung transplant (BLT) recipients. ⋯ Lung transplant can be offered to select older patients up to age 74 with acceptable outcomes. SLT may be preferred for elderly patients, but BLT offers acceptable long-term outcomes without significant short-term risk. Patients older than 75 have acceptable short-term outcomes for SLT, but long-term outcomes for SLT and BLT in this group are poor.
