Comparative Study Observational StudyAn exploratory panel of biomarkers for risk prediction in pulmonary hypertension: emerging role of CT-proET-1.
Pulmonary arterial hypertension (PAH) is a rare, deadly condition. Although risk stratification is extremely important for assessment of prognosis and to guide therapy, there is lack of evidence concerning the role of novel biomarkers. In a pivotal study, we sought to comparatively investigate the predictive power of several new biomarkers in PAH. ⋯ CT-proET-1 provided prognostic information independent of other biomarkers. Importantly, we have provided the first evidence that CT-proET-1 may be superior to commonly used biomarkers.

Comparative StudyAn oversized allograft is associated with improved survival after lung transplantation for idiopathic pulmonary arterial hypertension.
Idiopathic pulmonary arterial hypertension (IPAH) is associated with high short-term mortality after bilateral lung transplantation (BLT). Previous studies have suggested that oversized allografts are associated with improved outcomes and that this association was strongest within the first year after transplant. We hypothesized that oversizing the allograft is associated with improved survival after BLT for IPAH. ⋯ Oversizing the allograft is associated with improved survival after BLT for IPAH. In the setting of donor organ shortages and waiting list mortality, it is not practical to intentionally oversize the allograft. However, the pTLC ratio could provide further refinement in the peri-transplant risk assessment.

Comparative StudyImpact of concomitant cardiac procedures performed during implantation of long-term left ventricular assist devices.
There is a paucity of data evaluating the effect of performing a concomitant cardiac procedure (CCP) on peri-operative survival in patients undergoing implantation of long-term left ventricular assist devices (LVADs). The objective of this study was to review our single-institutional experience with patients who underwent a CCP during implantation of a long-term continuous-flow LVAD. ⋯ CCPs performed during implantation of a long-term continuous-flow LVADs does not increase peri-operative or mid-term mortality. In addition, unlike previous reports, there was no additive procedural risk for patients undergoing concomitant aortic valve repair or replacement.
