• For patients diagnosed with acute pulmonary embolism (PE), the prognostic significance of concomitant right heart thrombi (RHT) lacks clarity. We performed a meta-analysis of studies that enrolled patients with acute PE to assess the prognostic value of echocardiography-detectable RHT for the primary outcome of short-term all-cause mortality and the secondary outcome of short-term PE-related mortality. Unrestricted searches were conducted of PubMed and Embase from 1980 through January 31, 2016, and used the terms "right heart thrombi," "pulmonary embolism," and "prognos.*" A random effects model was used to pool study results; Begg rank correlation method was used to evaluate for publication bias; and I testing was used to assess for heterogeneity. Six of 79 potentially relevant studies met the inclusion criteria (15,220 patients). Overall, 99 of 593 patients with echocardiography-detectable RHT died (16.7% [95% CI, 13.8-19.9]) compared with 639 of 14,627 without RHT (4.4% [95% CI, 4.0-4.7]). RHT had a significant association with short-term all-cause mortality in all patients (OR, 3.0 [95% CI, 2.2 to 4.1]; I  = 20%) and with PE-related death (three cohorts, 12,955 patients; OR: 4.8 [95% CI, 2.0-11.3; I  = 76%). Results were consistent for the prospective (two cohorts, 514 patients; OR, 4.8 [95% CI, 1.7-13.6]; I  = 56%) and the retrospective (four cohorts, 14,706 patients; OR, 2.8 [95% CI, 2.1 to 3.8]; I  = 0%) studies. In patients diagnosed with acute PE, concomitant RHT were significantly associated with an increased risk of death within 30 days of PE diagnosis.
