Inventional cardiologist and heart valve specialist Dr. Guilherme Attizzani completed cardiology training at Dante Pazzanese Institute, University of Sao Paulo, Brazil, which is the largest cardiology hospital in Latin America. He also completed two years of interventional cardiology training there and then moved to the U.S. for a three-year research fellowship in intravascular imaging.

As a heart disease specialist, Dr. Attizzani has become one of the world’s greatest experts in intravascular optical coherence tomography (OCT). His outstanding research has helped improve stent implantation techniques, enabled a better understanding of vascular healing after drug-eluting stent implantantion, and revealed important features of unstable coronary plaques. Dr. Attizzani published several scientific papers on OCT and was the editor of a book entirely dedicated to this modality. He has also trained hundreds of physicians worldwide on OCT.

With the development of structural heart disease interventions, in particular the implantation of transcatheter heart valves, Dr. Attizzani sought specialized training in this growing field. He went to Italy to train for two years in a clinical fellowship devoted exclusively to valve and structural heart intervention at Ferrarotto Hospital, University of Catania, one of Europe’s largest volume centers for transcatheter valves.

Dr. Attizzani was recruited at University Hospitals Harrington Heart & Vascular Institute in 2014 as part of the Valve and Structural Heart Disease Center team, and in 2016 became director of the program.

Dr. Attizzani has become a world leader in optimal practices and the minimalist approach (procedure performed under local anestesia only) for transcatheter aortic valve replacement, or TAVR. His extensive experience includes implant and oversight of more than 1,300 transcatheter heart valves. He travels all over the U.S. teaching physicians how to optimally implant these devices. In addition, Dr. Attizzani’s expertise has led him to help launch the use of transcatheter heart valve interventions in Japan where he continues to proctor physicians.

Patient Satisfaction Reviews

About Our Survey

At University Hospitals, we believe in providing patients with all the information they need to make educated decisions about their health care and to choose the right doctor to meet their needs. That is why we partner with the independent patient satisfaction company Press Ganey to survey patients about their experiences at UH facilities and with UH physicians. We hold ourselves to the highest standards of care and are dedicated to creating a positive patient experience for every individual who sees a UH doctor.

Industry Relationships

University Hospitals is committed to transparency in our interactions with industry partners, such as pharmaceutical, biotech, or medical device companies. At UH, we disclose practitioner and their family members’ ownership and intellectual property rights that are or in the process of being commercialized. In addition, we disclose payments to employed practitioners of $5,000 or more from companies with which the practitioners interact as part of their professional activities. These practitioner-industry relationships assist in developing new drugs, devices and therapies and in providing medical education aimed at improving quality of care and enhancing clinical outcomes. At the same time, UH understands that these relationships may create a conflict of interest. In providing this information, UH desires to assist patients in talking with their practitioners about industry relationships and how those relationships may impact their medical care.

UH practitioners seek advance approval for certain new industry relationships. In addition, practitioners report their industry relationships and activities, as well as those of their immediate family members, to the UH Office of Outside Interests annually. We review these reports and implement management plans, as appropriate, to address conflicts of interest that may arise in connection with medical research, clinical care and purchasing decisions.
