Y1 - 2018 N1 - T2 - Color Atlas and Synopsis of Interventional Cardiology AB - A 63-year-old man arrives in the emergency department with acute shortness of breath. His past medical history is remarkable for well-controlled hypertension. On admission, his heart rate is 113 bpm, oxygen saturation is 91%, and respiratory rate is 35 breaths/min. His blood pressure is 145/65 mm Hg. He underwent knee replacement surgery 15 days earlier. His physical examination is unremarkable, as are an electrocardiogram and chest radiograph. Computed tomography pulmonary angiography of the chest demonstrates large thrombi in the right and left main pulmonary arteries, extending into the lobar branches. His right-to-left ventricular ratio is markedly increased at 1.2, and troponin is elevated. Echocardiography performed at the bedside reveals moderate right ventricular hypokinesis and dilation. He is started on intravenous heparin and admitted to the intensive care unit.
