Regarding Ask Dr. Z question ID #3482, do you still recommend 93799, or does 37248 apply here? Example 1: The fenestration was crossed and was balloon test occluded for 10 minutes. The Fontan pressures rose to 16 mmHg, and we decided not to close it. Example 2: Test Occlusion: The fenestration was easily crossed using a 4 French JR4 catheter over a 035 Tureumo guidewire. The catheter was exchanged to a 4 French wedge over a 018 V-18 wire. The fenestration was temporarily test occluded for 10 minutes by inflating the wedge catheter, and repeat hemodynamic evaluation was performed using the LFV catheter. There was mild elevation in his PAp=15 mmHg and arterial saturation increased from 95 to 96%. However, his overall Qs decreased to 2.9.
