There is a lack of comprehensive data on the prevalence, predictors and prognostic significance of right heart thrombi (RHT) in pulmonary embolism.In this study of patients with pulmonary embolism from the Registro Informatizado de la Enfermedad TromboEmbólica (RIETE) registry, we assessed the prevalence and predictors of RHT, and the association between the presence of RHT and the outcomes of all-cause mortality, pulmonary embolism-related mortality, recurrences, and major bleeding through 30 days after initiation of pulmonary embolism treatment.Of 12 441 patients with pulmonary embolism and baseline echocardiographic data, 2.6% had RHT. The following increased the risk of RHT: younger age, previous bleeding, congestive heart failure, cancer, syncope, systolic blood pressure <100 mmHg, and arterial oxyhaemoglobin saturation <90%. Patients with RHT were significantly more likely to die from any cause (adjusted OR 2.50 (95% CI 1.62-3.84); p<0.001) and from pulmonary embolism (adjusted OR 4.29 (95% CI 2.45-7.48); p<0.001) during follow-up. RHT was associated with an increased risk of recurrence during follow-up (1.8% versus 0.7%; p=0.04). Major bleeding was similar in patients with and without RHT.In patients presenting with pulmonary embolism, RHT is relatively infrequent. Patients with RHT had a worse outcome when compared with those without RHT.

Significant differences in the clinical profile of venous thromboembolic-related outcomes were observed according to the site of cancer. These findings suggest the development of cancer-specific anticoagulant strategies as an area for further research.

Venous thromboembolism (VTE) during or after assisted reproductive technologies (ART) is predicted to rise due to the increased number of women undergoing this technique. We present data collected in the RIETE registry up to October 2016. Overall, 41 (0.6%) out of 6,718 women of childbearing age with VTE had an ART-related event. Most of them underwent autologous ART cycles; 23 had isolated deep vein thrombosis (DVT) (56.1%), 12 isolated pulmonary embolism (PE) (29.3%) and 6 simultaneous occurrence of both the events (14.6%). VTE occurred in 20 successful and 21 unsuccessful (i.e. not resulting in a clinical pregnancy) ART cycles. No recurrence was observed at 90 days. Logistic regression showed that isolated PE was significantly more frequent than DVT alone or combined with PE in unsuccessful in vitro fertilization (IVF) (odds ratio [OR]: 4.13, 95% confidence interval [CI]: 1.4–12.4), as well as in contraceptive users (OR: 2.96, 95% CI: 1.95–4.5) and in puerperium (OR: 1.96, 95% CI: 1.16–3.3). After grouping isolated PE and DVT + PE, we found that PE was significantly more frequent in women with unsuccessful IVF and higher body mass index (OR: 5.0, 95% CI: 1.2–20.7 and OR: 1.0, 95%CI: 1.0–1.1, respectively). These data document a higher risk of PE in unsuccessful cycles than in successful ones. The risk is higher than that observed during pregnancy, puerperium and contraception.
