Impact of Left Ventricular Diastolic Dysfunction on Lung Transplantation Outcome in Patients With Pulmonary Arterial Hypertension

Diastolic dysfunction may influence perioperative outcome, early graft function, and long‐term survival. We compared the outcomes of double lung transplantation (DLTx) for patients with pulmonary arterial hypertension (PAH) with preoperative left ventricular (LV) diastolic dysfunction with the outco...

Description
Summary:	Diastolic dysfunction may influence perioperative outcome, early graft function, and long‐term survival. We compared the outcomes of double lung transplantation (DLTx) for patients with pulmonary arterial hypertension (PAH) with preoperative left ventricular (LV) diastolic dysfunction with the outcomes of patients without diastolic dysfunction. Of 116 consecutive patients with PAH (who underwent transplantation between January 1995 and December 2013), 44 met our inclusion and exclusion criteria. Fourteen (31.8%) patients with diastolic dysfunction pretransplantation had a higher body mass index (29 [IQR 21.5–32.6] vs 22.4 [IQR 19.9–25.3] kg/m2) and mean pulmonary arterial pressure (54.6 ± 10 mmHg vs 47 ± 11.3 mmHg) and right atrial pressure (16.5 ± 5.2 mmHg vs 10.6 ± 5.2 mmHg). The patients received extracorporeal life support more frequently (33% vs 7% [p = 0.02]), had worse APACHE II scores (21.7 ± 7.4 vs 15.3 ± 5.3 [p = 0.02]), and a trend toward worse ventilator‐free days (2.5 [IQR 6.5–32.5] vs 17 [IQR 3–23] [p = 0.08]). There was no effect on development of primary graft dysfunction or intensive care unit/hospital survival. One‐year survival was worse (hazard ratio [HR] 4.45, 95% confidence interval [CI] 1.3–22, p = 0.02). Diastolic dysfunction was the only variable that correlated with overall survival (HR 5.4, 95% CI 1.3–22, p = 0.02). Diastolic dysfunction leads to early postoperative morbidity and worse survival in patients with PAH after DLTx. Left ventricular diastolic dysfunction is associated with worse perioperative course and survival in the first year after lung transplantation for pulmonary arterial hypertension.
