"I also had a 70% pericardectomy. My surgery lasted a total of 13 hours. Dr Unai was unbelievable and without him I believe I would not have survived all of my problems. I am returning on Sept 12th 2019 for a checkup as I wish to stay in touch with the Cleveland Clinic and Dr Unai in case I need help in the future. Much gratitude for Dr Unai and his entire team who could not have been more compassionate and helpful in my struggle to survive. I am truly grateful to have found them."
