About Juhana Karha
Dr. Juhana Karha was born in Finland, raised in Chicago, and happy to now call Austin, Texas his home. He earned his undergraduate degree at the University of Chicago and went on to receive his medical degree from Northwestern University Medical School. Post-graduate training began with an Internal Medicine internship and residency from Brigham and Women’s Hospital at Harvard University. He completed a cardiovascular medicine and interventional cardiology fellowship at the Cleveland Clinic Foundation. Dr. Karha is the author of 23 peer-reviewed scientific publications and several cardiology textbooks.
He joined Austin Heart in 2008 specializing in Interventional Cardiology, Peripheral Vascular Intervention, PFO/ASD closure, Carotid Stenting, Structural Heart Intervention, such as mitral and pulmonic valvuloplasty, and the Transcatheter Aortic Valve Replacement (TAVR). Partnering with interventional cardiologist, Dr. Frank Zidar, and Cardiovascular and Thoracic Surgeons Drs. Stephen Dewan and Faraz Kerendi, they established the first Heart Valve Clinic in Central Texas located at the Heart Hospital of Austin, utilizing a new treatment in valve replacement, called TAVR. By collaboratively combining the skills and knowledge of both cardiovascular surgeons and interventional cardiologists, patients with valve disease now have a new treatment option.
Dr. Karha is board certified in internal medicine, interventional cardiology, and cardiovascular medicine. He is board certified in the interpretation of non-invasive vascular studies (RPVI) and certified in nuclear cardiology by the Certification Board of Nuclear Cardiology. Dr. Karha also serves as an Austin Heart Med Exec committee member.
He and his wife have 3 children, 2 girls and a boy. When Dr. Karha is not providing care to his patients, he is enjoying sports and time with his family.
