7. A method comprising:
intravenously directing first bubbles into a patient's venous circulatory system and to a right side of the patient's heart, the first bubbles having sizes that fall within a first range;
monitoring the patient's heart, with ultrasound imaging, and detecting presence of the first bubbles on a left side of the patient's heart;
after detecting of the first bubbles on the left side of the patient's heart, intravenously directing second bubbles into the patient's venous circulatory system and to the right side of the patient's heart, the second bubbles having sizes that are greater than sizes in the first range;
monitoring the patient's heart, with ultrasound imaging, to detect presence of the second bubbles on the left side of the patient's heart;
if the presence of the second bubbles is not detected on the left side of the patient's heart, then administering a prophylactic medication; and
if the presence of the presence of the second bubbles is detected on the left side of the patient's heart, then surgically closing a shunt in the patient's heart.
