Thrombolytic therapy was associated with lower short-term mortality compared to anticoagulation alone (13.7% vs 37.1%; OR 4.83, 95% CI 1.52-15.36) in patients with right heart thrombi.

Does thrombolysis or surgical embolectomy reduce short-term mortality compared to anticoagulation alone in patients with right heart thrombi and pulmonary embolism?
Aggressive management with thrombolysis or surgical thrombectomy may be more effective than anticoagulation alone for reducing short-term mortality in patients with right heart thrombi and pulmonary embolism.
Odds Ratio: 4.83 (95% CI 1.52–15.36)
Tasa de eventos absoluta: 13.7% vs 37.1%
The objective was to compare the efficacy of treatment options for right heart thrombi (RHT) in transit. All published reports between 1992 and 2013 were identified and pooled. We analyzed 328 patients with RHT and pulmonary embolism (PE). The treatments administered were none in 11 patients (3.4%), anticoagulation (AC) with heparin in 70 patients (21.3%), thrombolytics in 122 patients (37.2%), catheter-related treatments in five patients (1.5%) and surgical embolectomy in 120 patients (36.6%). The overall short-term mortality for the entire cohort was 23.2%. The mortality rate associated with no therapy was highest at 90.9%. The mortality associated with AC alone was significantly higher than surgical embolectomy or thrombolysis (37.1% vs 18.3% vs 13.7%, respectively). In univariate analysis, any therapy was better than no therapy with a favorable odds of 16.92 (95% CI 2.05-139.87) for AC, 61.76 (95% CI 7.42-513.81) for thrombolysis and 44.54 (95% CI 5.42-366.32) for surgical embolectomy. In multivariate analysis with age and hemodynamic status entered as covariates, thrombolytic therapy was better than AC with favorable odds of 4.83 (95% CI 1.52-15.36). Similarly, there was a trend in favor of surgical embolectomy with an odds of 2.61 (95% CI 0.90-7.58). The estimated probability of survival in hemodynamically unstable patients with AC, surgical embolectomy and thrombolysis was 47.7%, 70.45% and 81.5%, respectively. There was no significantly increased risk of complications with thrombolytic therapy. In conclusion, left untreated, patients with RHT and PE have very high mortality. Aggressive management with thrombolysis or surgical thrombectomy may be more effective than AC alone in the management of these patients.
Athappan et al. (Wed,) conducted a meta-analysis in Right heart thrombi (RHT) and pulmonary embolism (PE) (n=328). Thrombolysis vs. Anticoagulation alone was evaluated on Short-term mortality (OR 4.83, 95% CI 1.52-15.36). Thrombolytic therapy was associated with lower short-term mortality compared to anticoagulation alone (13.7% vs 37.1%; OR 4.83, 95% CI 1.52-15.36) in patients with right heart thrombi.
