Division of Cardiology, Indiana University School of Medicine, Indianapolis, Indiana, USA; and Eskenazi Health Center, Indianapolis, Indiana, USA.

Many dyspneic patients who undergo computerized tomographic pulmonary angiography (CTPA) for presumed acute pulmonary embolism (PE) have no identified cause for their dyspnea yet have persistent symptoms, leading to more CTPA scanning. Right ventricular (RV) dysfunction or overload can signal treatable causes of dyspnea. We report the rate of isolated RV dysfunction or overload after negative CTPA and derive a clinical decision rule (CDR). Read More

Relationship of clot burden and echocardiographic severity of right ventricular dysfunction after acute pulmonary embolism.

Int J Cardiovasc Imaging 2015 Mar 27;31(3):509-15. Epub 2014 Nov 27.

Echocardiography Laboratory - MDP, Hospital Israelita Albert Einstein, São Paulo, Brazil,

The impact of pulmonary embolism on right ventricular (RV) performance can be evaluated by echocardiography, however, the relationship between pulmonary vascular involvement and RV burden is controversial. To assess the effect of clot burden on RV performance we studied 85 patients (aged 53 ± 17 years, 39 female) with confirmed PE by multislice computed tomography (CT) and echocardiography within 24 h of diagnosis. A CT score ranging from 1 to 20 points according to the pulmonary arteries involved was used. Read More

CT-derived atrial and ventricular septal signs for risk stratification of patients with acute pulmonary embolism: clinical associations of CT-derived signs for prediction of short-term mortality.

Int J Cardiovasc Imaging 2014 Jun 29;30 Suppl 1:25-32. Epub 2014 Apr 29.

Division of Cardiology, Department of Internal Medicine, Incheon St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Incheon, Republic of Korea.

A left-bulging atrial septum (AS) is an abnormal sign indicating hemodynamic overloading of the right heart. We tried to evaluate whether computed tomography (CT)-derived AS bulging and ventricular septum (VS) bowing signs would be used to identify patients with acute pulmonary embolism (PE) and significant hemodynamic derangements. In the prospective registry, 208 consecutive patients with a first episode of acute PE diagnosed by chest CT were grouped by clinical hemodynamic assessment: massive or submassive PE (Group 1), and small PE (Group 2).
