Multicenter Study Clinical TrialExtended post-ex vivo lung perfusion cold preservation predicts primary graft dysfunction and mortality: Results from a multicentric study.
Ex vivo lung perfusion (EVLP) allows for a reassessment of lung grafts initially deemed unsuitable for transplantation, increasing the available donor pool; however, this requires a pre- and post-EVLP period of cold ischemic time (CIT). Paucity of data exists on how the sequence of cold normothermic-cold preservations affect outcomes. ⋯ Extended cold post-EVLP preservation is associated with a risk for PGD and 1-year mortality. Pre-EVLP CIT does not increase mortality or high-grade PGD. These findings from a multicenter trial should caution on the implementation of extended cold preservation after EVLP.

Multicenter StudyArtificial intelligence for early prediction of pulmonary hypertension using electrocardiography.
Screening and early diagnosis of pulmonary hypertension (PH) are critical for managing progression and preventing associated mortality; however, there are no tools for this purpose. We developed and validated an artificial intelligence (AI) algorithm for predicting PH using electrocardiography (ECG). ⋯ The AI algorithm demonstrated high accuracy for PH prediction using 12-lead and single-lead ECGs.

Elevated pulmonary arterial elastance and right ventricular uncoupling are associated with greater mortality in advanced heart failure.
The objectives of this study were to describe right ventricular-pulmonary arterial elastance coupling hemodynamic phenotypes and their frequency in patients with advanced heart failure and to evaluate the association of elastance-based indices with all-cause mortality, cardiac transplantation, and left ventricular assist device therapy. ⋯ Right ventricular-pulmonary vascular coupling is frequently impaired in heart failure and associated with greater mortality. Elevated pulmonary arterial elastance is associated with greater mortality even when coupling is preserved.

Predicted heart mass-based size matching among recipients with moderate pulmonary hypertension: Outcomes and sex effect.
There is a lack of evidence to guide appropriate donor sizing in recipients with moderate pulmonary hypertension (pHTN) awaiting heart transplantation (HTx). It is common practice to oversize donor hearts for such recipients to prevent post-operative right ventricular failure. Therefore, our objective was to determine if oversizing in pre-transplant moderate pHTN provides a survival advantage. ⋯ In this registry-based analysis, there was no benefit to oversizing donors for cardiac transplant recipients with moderate pHTN. Elimination of this restriction could increase the donor pool and reduce wait times for such recipients.
