We just spoke with Dr. Glatz, Zoe's interventional cardiologist, who reviewed the preliminary results of this morning's MRI of Zoe's heart. He indicated that everything looked good on the MRI, but some slight narrowing of the left pulmonary artery remains; he also saw a decent amount of collaterals.
Zoe's left pulmonary artery has a history of narrowing. In September of 2010, Dr. Spray performed the hemi-Fontan, instead of the Glenn, since her left pulmonary artery was narrowed, and went ahead and patched the artery to the lung. Later, in July of 2011, Dr. Glatz observed further narrowing during a cath and ballooned it open to increase blood flow. On today's MRI, he didn't think it looked narrowed enough that it would require intervention, but suggested there was a possibility Dr. Spray may want to patch it again tomorrow, which ads a step to the Fontan. He'll consult with Dr. Spray during the cath, if necessary, once he's inside her pulmonary arteries/heart.
Because of the amount of presence of collateral vessels, he indicated he planned to go ahead and coil/embolize. The theory is that by coiling, it lowers the pulmonary pressures, which can lessen the most common side effect of the Fontan, fluid retention in the chest.
Because of the cath and intervention, Zoe will spend the night in the hospital tonight and have her Fontan first thing in the morning. She may experience lowered oxygen saturations tonight and low-grade fever due to the coiling.
We'll get the next update in about an hour.
