BACKGROUND: Lung transplantation (LuTx) is a challenge when right heart function fails. Mechanical circulatory support (MCS) is then necessary.
METHODS: We aimed to investigate whether preoperative transthoracic echocardiography (TTE) can predict MCS use and help to exclude the sickest patients. Between 2011 and 2018, 52 patients at our institution received LuTx and qualified for this study: 35 bilateral, 16 single, 1 lobar [1] and 1 retransplantation procedure. Of these, 22 were operated using MCS and 30 without MCS. The patients were aged between 18 and 65 years, and 23 were women. The indications were lung fibrosis for 18 patients, chronic obstructive lung disease for 16, cystic fibrosis for 15, primary pulmonary hypertension for 2 and bronchiectasis for 1. TTE was performed up to 30 days before treatment and 1 to 7 days after.
RESULTS: Patients undergoing MCS versus patients not undergoing MCS: preoperative right ventricular systolic pressure 56.5 (30) vs 37.8 (11.5) mm Hg (P = .03); tricuspid regurgitation pressure gradient 48.7 (27) vs 30.2 (10.8) mm Hg (P = .015); tricuspid annular plane systolic excursion 17.8 (4.3) vs 19.9 (2.8) mm Hg (P = .04); pulmonary artery diameter 27.5 (5.2) vs 23.9 (4.1) mm (P = .004); age 41.9 (14.1) vs 54.3 (11.8) years (P = .001). Patients who were Dead versus patients who were alive pulmonary valve acceleration time of 82.8 (24.1) vs 104.9 (27.2) ms (hazard ratio [HR] = 0.959, 95% confidence interval [CI] = 0.923-0.996 per ms, P = .02) and pulmonary artery diameter of 28.9 (5.8) vs 24.4 (4.1) mm HR = 1.225, 95% CI = 1.028-1.460 per 1 mm, P = .016 were predictors of death.
CONCLUSIONS: Preoperative TTE parameters: right ventricular systolic pressure, tricuspid regurgitation pressure gradient, tricuspid annular plane systolic excursion, and pulmonary artery diameter predicted MCS use during LuTx. Certain values of valve acceleration time and pulmonary artery diameter could help discern LuTx qualification.
