It was the Big Day today. At 1pm, Ri underwent a procedure to drain the pericardial effusion and to take a sample of the mass for biopsy. By 4pm, she was moved to the Pediatric ICU for close observation overnight. When I went to see her at PICU, she looked fine although still groggy from the anesthesia. Her cardiovascular and thoracic surgeon, Dr. Karl Reyes, said he drained about 500 cc of fluid. A pericardial drain was left attached to Ri to collect in the next few days whatever fluid is left.
