Lehigh Valley Health Network will be one of the nation’s first hospitals performing a new procedure in which a heart valve is replaced using a catheter. This innovation is for adults with severely diseased aortic valves who are not eligible for traditional open-heart valve replacement surgery. The procedure – called transcatheter aortic valve replacement (TAVR) – will be performed in the health network’s new hybrid operating room (OR), which contains both OR and cardiac catheterization lab imaging and equipment. Clinicians in the hybrid OR are specially educated in both heart surgery and cardiac catheterization. Health network heart specialists expects to begin performing the procedure in early spring.
