Abstract

SummaryBackground Right ventricular failure (RVF) is a major cause of morbidity and mortality in left ventricular assist device (LVAD) recipients. Objectives To identify preoperative echocardiographic predictors of post-LVAD RVF. Methods Data were collected for 42 patients undergoing LVAD implantation in Germany. RVF was defined as the need for placement of a temporary right ventricular assist device or the use of inotropic agents for 14 days. Data for RVF patients were compared with those for patients without RVF. A score (ARVADE) was established with independent predictors of RVF by rounding the exponentiated regression model coefficients to the nearest 0.5. Results RVF occurred in 24 of 42 LVAD patients. Univariate analysis identified the following measurements as RVF risk factors: basal right ventricular end-diastolic diameter (RVEDD), minimal inferior vena cava diameter, pulsed Doppler transmitral E wave (Em), Em/tissue Doppler lateral systolic velocity (SLAT) ratio and Em/tissue Doppler septal systolic velocity (SSEPT) ratio. Em/SLAT ≥ 18.5 (relative risk [RR] 2.78, 95% confidence interval [CI] 1.38-5.60; P = 0.001), RVEDD ≥ 50 mm (RR 1.97, 95% CI 1.21-3.20; P = 0.008) and INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) level 1 (RR 1.74, 95% CI 1.04-2.91; P = 0.04) were independent predictors of RVF. An ARVADE score > 3 predicted the occurrence of post-implantation RVF with a sensitivity of 89% and a specificity of 74%. Conclusion The ARVADE score, combining one clinical variable and three echocardiographic measurements, is potentially useful for selecting patients for the implantation of an assist device.
