An urgent echocardiogram was performed on a 36-year-old female who was admitted because of sudden-onset shortness of breath during a long-haul airplane flight. She gave a history of cough and hemoptysis two weeks PTA. She is a known asthmatic, maintained on ventolin and steroids. On physical examination, she was dyspneic, tachypneic, tachycardic, afebrile, and normotensive. ECG showed RBBB, RAD, and increased amplitude of P wave in lead II. PO2 was 74 mmHg with O2 saturation 95%. V/Q scan revealed almost complete absence of perfusion of the right lung and multiple segmental defects in the left lung. Echocardiography findings are shown in [Figure 1],[Figure 2],[Figure 3],[Figure 4]. She was treated with rTPA infusion. [Figure 4] demonstrates regression in size of thrombus with partial restoration of blood flow to distal pulmonary arteries 15 minutes after initiation of thrombolytic therapy. One hour later, the patient went into respiratory arrest and expired.

Abbreviations: RV = right ventricle; RA = right atrium; IVS = interventricular septum; LV = left ventricle; MPA = main pulmonary artery; RPA = right pulmonary artery; LPA = left pulmonary artery; TTE = transthoracic echocardiograpy
