Optimized definition of right ventricular dysfunction on computed tomography for risk stratification of pulmonary embolism.

Objectives: There is an ongoing discussion on the optimal right to left (RV/LV) diameter ratio threshold and the best definition of RV dysfunction on computed tomography pulmonary angiography (CTPA) for risk assessment of pulmonary embolism (PE).

Methods: On routine diagnostic CTPA, volumetric and diameter measurements (axial and reconstructed views) of the ventricles and reflux of contrast medium into the inferior vena cava (IVC) and hepatic veins were assessed in consecutive PE patients enrolled in a prospective single-center registry. In-hospital adverse outcome was defined as PE-related death, cardiopulmonary resuscitation, mechanical ventilation or catecholamine administration.

Impact of thyroid dysfunction on short-term outcomes and long-term mortality in patients with pulmonary embolism.

Background: A large body of evidence suggest an impact of thyroid function on outcomes of cardiovascular diseases, but results for acute pulmonary embolism (PE) are sparse.

Methods: We analysed the impact of hypothyroidism as well as hyperthyroidism on the short and long-term outcomes of patients with acute PE. The impact was compared to the group of euthyroid PE patients as reference group.

Prognostic value of right atrial dilation in patients with pulmonary embolism.

Aims: Right atrial (RA) dilation and stretch provide prognostic information in patients with cardiovascular diseases. We investigated the prevalence, confounding factors and prognostic relevance of RA dilation in patients with pulmonary embolism (PE).

Methods: Overall, 609 PE patients were consecutively included in a prospective single-centre registry between September 2008 and August 2017.
