Comparative Study
Early Outcomes With Marginal Donor Hearts Compared With Left Ventricular Assist Device Support in Patients With Advanced Heart Failure.
The shortage of donor hearts has limited cardiac transplantation for end-stage heart failure, leading to the increased use of left ventricular assist devices (LVADs) as bridge-to-transplant (BTT) and marginal donor hearts; however, outcomes have been mixed. This study examines differences in wait list survival of patients with continuous flow LVADs and post-transplantation survival of patients receiving a marginal donor heart. ⋯ There was no significant difference between waiting list survival of patients with LVAD support as BTT and post-transplant survival of recipients with marginal donor hearts. There could be clinical benefits for using LVAD support as BTT to allow time for better allocation of optimal donor hearts as opposed to transplantation with a marginal donor heart.

Case Reports
Combined Transcatheter Aortic Valve Replacement and Thoracic Endovascular Aortic Repair Using Transapical Access.
Vascular complications remain an important consideration when selecting access for delivery of large endovascular devices. With the advent of transcatheter aortic valve replacement, transapical access has become an acceptable technique when transfemoral or direct transaortic access is contraindicated. We report the use of the transapical approach during thoracic aortic endovascular repair in 2 patients, one of which included concomitant delivery of a transcatheter aortic valve replacement device. To our knowledge, this is the first reported case of a hybrid single-stage transcatheter aortic valve replacement and thoracic aortic endovascular repair using transapical access.

Lung transplantation (LTx) benefit for survival in cystic fibrosis (CF) patients placed on the wait list is not well studied. ⋯ The benefit of LTx in adults with CF was significant at a lower baseline FEV1 than expected. A threshold for baseline FVC was established below which LTx was protective.

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.

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.
