Patient Care
    The UC Heart & Vascular Center includes the only adult
cardiac transplant program in the region. Cardiac trans-
plant volume has been steady, and 20-30 transplants per
year are expected in the coming years. This multidisci-
plinary treatment effort has met with excellent clinical
results. Clinical services are performed at The University
Hospital, the Veterans Affairs Medical Center, and the
Cincinnati Children’s Hospital Medical Center.

     The Division performs a wide variety of operative
procedures in patients with cardiac and vascular diseases,
including off-pump coronary revascularization, modified
MAZE procedure for atrial fibrillation without the need for
a sternal incision, left ventricular assist device (LVAD) inser-
tion, heart transplantation for severe heart failure, as well as
all-arterial myocardial revascularization and mitral valve

           The Section of Cardiothoracic Surgery and the
      University of Cincinnati College of Medicine offer a course
      called “Summer Surgery Experience at UC.” This two-week
      program teaches 24 undergraduates from various colleges
      the art and science of surgery. Participants are exposed to
      cardiac anatomy and physiology, learning cardiac diagnos-
      tic techniques, receiving hands-on experience in the
      clinical skills lab, learning about the DaVinci robot, and
      shadowing in the operating room. The students also
      perform library research on several clinical cases and give a
      presentation at the close of the program. John Flege Jr., MD,
      serves as director of the program.

which the faculty participates. The Division serves as one
of the primary rotations of the Cardiothoracic Surgery
training program, based at UC.

    The research efforts within the Division continue to
grow with two basic science laboratories presently within
the Division, as well as the collaboration of Cardiothoracic
Surgical faculty with Cardiology and other faculty on a
number of clinical research projects.
