During the last 21 years, Dr. Gerdisch has performed more than 5,000 innovative surgical procedures, of which 3,500 involved heart valve operations. He is an innovator in heart surgery and presents internationally on novel heart valve repair techniques and participates in ongoing landmark research in next-generation heart valves and heart tissue regeneration.
Dr. Gerdisch’s list of innovations and firsts include:
2014: First in the United States to enroll patient in a landmark study, performing minimally invasive closure of the left atrial appendage to prevent strokes. He also was first in Indiana to use the Edwards SAPIEN XT Transcatheter Aortic Heart Valve.
2013: First in the United States to implant the On-X Aortic Prosthetic Valve with Anatomic Sewing Ring. The innovative valve is the only mechanical valve that matches the contour of the heart.
