The underlying mechanisms of PGD development are not completely understood. This study analyzed the effect of right ventricular function (RVF) on PGD development. Methods A retrospective analysis of a prospectively assessed cohort was performed at a single institution between July 2010 and June 2013. The primary outcome was development of PGD grade 3 (PGD3). Conventional echocardiographic parameters and speckle-tracking echocardiography, performed during the pre-transplant evaluation phase up to 1 year before surgery, were used to assess preoperative RVF. Results Included were 120 lung transplant recipients (LTr). Systolic pulmonary arterial pressure (48 ± 20 vs 41 ± 18 mm Hg; p = 0.048) and ischemia time (349 ± 73 vs 306 ± 92 minutes; p < 0.01) were higher in LTr who developed PGD3. Patients who developed PGD3 had better RVF estimated by basal free wall longitudinal strain (BLS; -24% ± 9% vs -20% ± 6%; p = 0.039) but had a longer intensive care unit length of stay and mechanical ventilation and higher 6-month mortality. BLS ≥ -21.5% was the cutoff that best identified patients developing PGD3 (area under the receiver operating characteristic curve, 0.70; 95% confidence interval, 0.54-0.85; p = 0.020). In the multivariate analysis, a BLS ≥ -21.5% was an independent risk factor for PGD3 development (odds ratio, 4.56; 95% confidence interval, 1.20-17.38; p = 0.026), even after adjusting for potential confounding. Conclusions A better RVF, as measured by BLS, is a risk factor for severe PGD. Careful preoperative RVF assessment using speckle-tracking echocardiography may identify LTrs with the highest risk of developing PGD.
