Endowed Chair Fulfills Dream of Congenital Heart Disease Program for Adults


A generation ago, adult cardiologists had little need to study congenital heart disease. Few children born with these heart conditions lived to adult age. Great advances have been made during the past few decades in caring for children with major structural heart issues (congenital heart diseases), allowing survival to adulthood and a productive life. Today, more adults are living with congenital heart disease than children with these conditions. This endowed chair provides an opportunity to make important strides toward fulfilling a dream of building a comprehensive adult congenital cardiology program for southern Arizona.

Marnell Endowed Chair for Research in Cardiothoracic Surgery Aims to Expand Options for Transplant Patients


Zain Khalpey, MD, PhD, MRCS (Eng), associate professor of surgery at the University of Arizona College of Medicine – Tucson, has been named the Tony A. Marnell, Sr. Endowed Chair for Research in Cardiothoracic Surgery at the UA Sarver Heart Center. One goal of his lab is to recondition human hearts and lungs unsuitable for transplantation by chemically stripping unusable cadaveric lungs of their cells, leaving a functional lung “bioscaffold.” This structure then can be “re-seeded” with autologous (a patient’s own) stem cells to rebuild the organ.
