Background: Point of care ultrasonography (POCUS) is modality being used in emergency medicine for last two decades.  Case Report: A 76 year old man was referred to the emergency department as flank pain and urolithiasis. However, he complained of dyspnea for a few days. At his triage examination oxygen saturation was 82% in room air. Pulmonary examination revealed bilateral rales with decreasing frequency, decreased respiratory sounds, and elongated expiration. A large-curve transducer (Philips HDI 5000 C5-2R 15 Hz transducer)  was used to examine the apical four chamber view on the obese patient in full sitting position leaning forward which was the only one could be reached at the point of care.  POCUS showed significant myocardial contractility of apex despite free wall hypokinesis of the right ventricle (RV) on visual qualitative evaluation of the apical four chamber view, confirmed as pulmonary thromboembolism of the bilateral branches of the pulmonary arteries. Conclusion: Point-of-care ultrasound can be extremely helpful tool to aid clinical assessment in emergency situations.
