A 16-year-old male patient underwent bilateral pulmonary embolectomy complicated by reperfusion injury and acute respiratory distress syndrome requiring venovenous extracorporeal membrane oxygenation support using a bicaval double-lumen catheter. A unique hemodynamic profile developed consistent with tamponade but without an associated decrease in venovenous extracorporeal membrane oxygenation pump flow, improved venovenous extracorporeal membrane oxygenation circuit preload, and decreased recirculation. The use of newer bicaval double-lumen catheters can result in old problems presenting in new ways and require clinicians to be ever vigilant.

Case Reports
Innominate pseudoaneurysm subtotally compressing the trachea as a result of blunt trauma.
Blunt traumatic innominate pseudoaneurysm is rare, and coexisting airway distress is even rarer. We describe a case of innominate pseudoaneurysm that subtotally compressed the trachea in a 45-year-old man. The patient also had bovine-type arch anatomy. ⋯ The pseudoaneurysm was eliminated and airway compression was completely relieved. The patient fully recovered without major complications. The unique feature of this case is its association with airway compression, which is uncommon but potentially lethal.

This study is a single-center experience with surgical repair of anomalous origin of left coronary artery from pulmonary artery (ALCAPA) with focus on the management of associated mitral regurgitation (MR). ⋯ Surgical repair of ALCAPA has good long-term results with low mortality and reintervention rates. The majority of MR is functional and will improve with reperfusion, but structural mitral valve abnormalities should be repaired at the time of surgery.

Lung transplantation (LTx) is significantly limited by donor organ shortage. Donor smoking history of more than 20 pack-years is considered an extended donor criterion. In this study, we retrospectively evaluated impact of donor smoking history and extent of smoking on midterm outcome after LTx. ⋯ In our experience, history and extent of donor smoking do not significantly affect early and midterm outcomes after LTx. Although this finding does not obviate the need for longer-term observation, donor lungs from even heavy smokers may not per se contraindicate LTx and may provide a valuable avenue for expanding donor organ availability.

Pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals (PA/VSD/MAPCAs) is a complex and diverse form of congenital heart defect. Although most patients with PA/VSD/MAPCAs can wait until they are 3 to 6 months of age to undergo surgical reconstruction, there are three specific criteria that merit an earlier repair. These 3 criteria are (1) unremitting heart failure; (2) a ductus to one lung and MAPCAs to the other; and (3) hemitruncus to one lung and MAPCAs to the other. The purpose of this study was to evaluate our surgical experience with early complete repair of PA/VSD/MAPCAs. ⋯ The data demonstrate that early complete repair of PA/VSD/MAPCAs can be accomplished with low mortality and excellent postoperative hemodynamics. These early hemodynamic results are maintained at medium-term follow-up. We conclude that early complete repair is an appropriate choice for this highly select subgroup of patients.
