Welcome to HealingWell. I am so glad you found us. Has you Dr. done a
Transesophageal echocardiography - an ultrasound test used to visualize the heart and defect, where an imaging probe with a camera is placed into the esophagus . The bubble test is normally done at this same time by the cardiologist that performs the TEE. I had 2 TEE's in one day - long story .
Try not to anticipate that you will not be able to resume you normal activities but do discuss these questions prior to surgery if you should need to go that way.
Thinking of you and please know I care.
