New ISHLT cardiac allograft vasculopathy standardized nomenclature

25.06.2010
A common international definition will benefit heart transplant patients

Cardiac allograft vasculopathy (CAV), the major limitation to long term survival after heart transplantation, occurs when blood vessels in a transplanted heart progressively narrow and lead to dysfunction of the heart muscle or sudden death.

Ascertaining benefit from appropriate treatment for this condition has been hampered in part because of the lack of a standard nomenclature. In an article published online today in The Journal of Heart and Lung Transplantation (www.jhltonline.org), clinicians representing the International Society for Heart and Lung Transplantation (ISHLT) Working Group on Classification of Cardiac Allograft Vasculopathy issued the first international consensus formulation of a standardized nomenclature for CAV.

"The development of cardiac allograft vasculopathy remains the Achilles heel of cardiac transplantation," commented working group leader, Mandeep R. Mehra, MD, Herbert Berger Professor and Head of Cardiology, University of Maryland School of Medicine, Baltimore, MD. "Unfortunately, the definitions of cardiac allograft vasculopathy are diverse and confusion abounds. There have been no uniform international standards for the nomenclature of this entity. The lack of a standard language has led to confusion in the interpretation of various studies and several unanswered questions persist. The ISHLT consensus statement is the first step in resolving these issues and improving cardiac transplant patient outcomes."

This consensus document, commissioned by the International Society for Heart and Lung Transplantation Board, is based on best evidence and clinical consensus derived from critical analysis of available information pertaining to angiography, intravascular ultrasound imaging, microvascular function, cardiac allograft histology, circulating immune markers, noninvasive imaging tests, and gene-based and protein-based biomarkers.

ISHLT President, John Dark, FRCS, stated, "The consensus document from the international working group led by Dr. Mehra defines the descriptors of the major clinical challenge late after cardiac transplantation. It also defines the ISHLT as the organization unifying all those, scientists and clinicians, working in this field, and able to put the stamp of authority on the recommendations. The topic is rapidly evolving, but Dr Mehra and his colleagues have undertaken to keep the data under close review. We can anticipate further definitive analyses in the future."

This article presents 5 consensus statements that describe how to best identify CAV and assess its severity. By developing a standard nomenclature, appropriate treatment options can be selected, depending on the level of CAV. Four levels of CAV are defined, ranging from CAV0 (not significant), where no angiographic lesions are detected, to CAV3 (severe), where multiple major heart vessels are involved. Key among the recommendations to define the severity of CAV is to view the anatomy of the allograft vasculature in concert with the physiological effects of the disease on cardiac allograft function.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
