Abstract

Background: In some patients with acute pulmonary embolism (APE) thrombi may lodge at the levels of the bifurcation of pulmonary trunk and extend into both main pulmonary arteries, forming so-called saddle embolism (SE).
Aim: To assess the incidence of SE and whether it is associated with an increased risk of complicated clinical course.
Methods: We studied 150 consecutive patients (94 females, 56 males) aged 63.6±16.7 years with APE confirmed with contrast enhanced spiral computed tomography or transesophageal echocardiography.
Results: SE was detected in 22 (14.7%) patients. Mean age (SE vs N-SE) was 64.3±17.4 vs 63.5±16.6 years, heart rate 100.8±14.1 beats/min vs 97.8±21.1 beats/min, systolic blood pressure 126.2±20.1 vs 127.1±23.3 mmHg and blood pulsoximetry 92 (68-98) vs 91 (30-98) % (all differences NS). In patients with SE, echocardiographic signs of the right ventricular overload, defined as right to left ventricular end - diastolic ratio >0.6 with right ventricular hypokinesia and/or maximal tricuspid peak systolic gradient >30 mmHg with shortened acceleration time of pulmonary ejection
