Background: Right ventricular dysfunction (RVD) is the main determinant of mortality in patients with pulmonary embolism (PE). Thus, guidelines recommend the assessment of RVD with transthoracic echocardiography (TTE) or computed tomography pulmonary angiography (CTPA) among these patients. In this study, we investigated the agreement between TTE and CTPA for the detection of RVD. Materials and Methods: This single-center retrospective study included patients who were diagnosed with CTPA and underwent TTE within the first 24 hours following the diagnosis. Results: Two hundred fifty-eight patients met the inclusion criteria. In 71.3% (184) of them, CTPA and TTE agreed on both the presence and absence of RVD. There was a moderate agreement between the 2 tests (Cohen’s kappa = 0.404, P < .001). The agreement between right ventricle dysfunction on TTE and the increased right ventricle/left ventricle (RV/LV) on CTPA was fair (Cohen’s kappa = 0.388, P < .001). Three patients died due to PE, and another 5 patients required urgent reperfusion therapy. Overall, adverse outcomes occurred in 4% (8) of patients. The sensitivity of modalities in the detection of adverse outcomes was 100%. Transthoracic echocardiography was more specific compared to CTPA (43% vs. 28%). Statistically, flattening/bulging of the interventricular septum on TTE was significantly associated with adverse outcomes. No individual CTPA parameter was related to adverse outcomes. Conclusion: Both CTPA and TTE are reliable imaging modalities in the detection of RVD. However, TTE is more specific, and this may help in the identification and appropriate management of patients at higher risk of decompensation. A combination of CTPA parameters rather than individual RV/LV ratios increases the sensitivity of CTPA.

Sarcoidosis is a multi-system disease of unknown etiology characterized by non-caseating granulomatous inflammation. Determining the characteristics and prognosis of sarcoidosis cases and revealing the factors that may affect the prognosis are important for approach to patient. This study was planned to obtain prognosis data for our country and to determine the factors affecting the prognosis. 188 patients, followed regularly for three years or more, admitted to Ankara University Faculty of Medicine, Department of Chest Diseases between 2012-2017 were evaluated retrospectively. Increased radiological findings, functional impairment and any of the clinical conditions requiring initiation/modification of treatment were accepted as progression. Clinical status of the patients at the last follow-up was defined as remission with treatment, spontaneous remission, stable disease, progression, chronic case and recurrence. Spontaneous remission and remission with treatment, regression, stable disease, and recurrence that followed without treatment and didn’t cause symptom or functional impairment were accepted in good prognosis group. Progression, chronic cases that couldn’t be followed without treatment and recurrence requiring treatment were included in poor prognosis group. 58% of patients was accepted in good prognosis and 42% had poor prognosis group. During follow-up, spontaneous remission rate was 20.2%, pulmonary hypertension development rate was 10.6% and mortality rate was 4.25%. Low radiological stage, high spirometry and diffusion capacity values, being asymptomatic and having no previous treatment were associated with spontaneous remission and good prognosis. Increase in serum angiotensin converting enzyme and C-reactive protein and decrease in spirometry parameters and diffusion capacity values were associated with progression.
