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: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
