A 24-yeаr-оld mаle wаs admitted tо the surgical ICU fоllowing open reduction and internal fixation of a tibial fracture after symptoms consistent with a transient ischemic attack in phase II of recovery. All workup thus far has remained inconclusive of a cause to include MRI/MRA, echocardiogram, telemetry, and EEG. The next day he has downtrending hemoglobin and platelets, an increase in serum creatinine, and a temperature of 38.8 without leukocytosis or leukopenia. His surgical site is without any obvious sign of infection. Physical examination is remarkable for petechiae seen all over his body. Blood smear reveals schistocytes.

A 54-yeаr-оld femаle develоps fevers аnd cоugh on the final day of her vacation on a cruise ship in the Caribbean. She returns to her home in Florida, and over the following 3 days, she has continued fevers, productive cough, and new dyspnea on exertion. She presents to the ED and her vitals at that time are T 39°C, BP 110/80 mm Hg, HR 95 beats per minute, respiratory rate 21 breaths per minute, and SpO2 85% breathing ambient air. Her chest radiograph demonstrates multifocal patchy opacities and increased interstitial markings throughout all lung fields. Ceftriaxone and azithromycin are administered, along with 2 L of lactated ringers solution intravenously and her urinary Legionella antigen subsequently returns positive. She is admitted to the ICU on high-flow nasal cannula at FiO2 0.7 and flow 50 L per minute.  Which of the following statements is most accurate regarding Legionella pneumonia?

Vital signs on presentation are: Temp 36.3, BP 200/89 mmHg, HR 81 bpm, RR 18, O2 sat 93% on RA. Laboratory studies are notable for a cardiac troponin that is undetectable. 12-lead ECG demonstrates normal sinus rhythm with Q-waves in inferior leads, and nonspecific ST-segments changes. A CXR is obtained.  CXR3.jpg Bedside point-of-care ultrasound demonstrates a moderate-sized circumferential pericardial effusion. Which of the following is the most appropriate next step in work-up?
