This is a biopsy of the heart tissue inside the heart. The procedure involves
placement of a catheter through a vein in the neck or groin area while
the mildly sedated patient is lying on a table. The catheter is advanced
through the vessel into the heart with the assistance of x-ray pictures.
Samples of the heart tissue are removed and examined for evidence of abnormalities
by a tiny scoop on the end of the catheter. The cardiologist will send
the samples for review at any issues with the tissue. The procedure takes
less than one hour.
