Scintigraphy using iodine-123-metaiodobenzylguanidine (I-123-MIBG) has been used to demonstrate that >50% of orthotopically transplanted hearts undergo partial cardiac sympathetic re-innervation and that this occurs no earlier than 1 year post-transplant. This study used planar and singe-photon emission computed tomography (SPECT) I-123 MIBG scintigraphy to show that cardiac re-innervation was not detectable in any of the 8 patients studied 1.1 to 6.3 years post-heterotopic transplantation. Thus, potential for cardiac re-innervation varies according to the type of procedure performed.

UI MeSH Term Description Entries
D007457 Iodine Radioisotopes Unstable isotopes of iodine that decay or disintegrate emitting radiation. I atoms with atomic weights 117-139, except I 127, are radioactive iodine isotopes. Radioisotopes, Iodine
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
D013564 Sympathetic Nervous System The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.
