Snapshot A 65-year-old man presents to the emergency department for worsening shortness of breath over the course of 2 weeks. He noticed that his feet are swelling and that he feels short of breath when climbing the stairs or walking more than 2 blocks. Medical history is significant for a myocardial infarction approximately 1 month ago which he required a drug-eluting stent. Physical examination is notable for bibasilar crackles, jugular venous distension, and bilateral lower extremity edema. A chest radiograph is obtained, which demonstrates bilateral pleural effusion, cephalization, and Kerley lines.
