The center has eighty-nine beds—including six in its intensive care unit—eleven doctors and 180 staff, and handles an average of 120 outpatients a day. Hayama Heart has a stellar reputation for both surgery and rehabilitation, and was the first facility in Japan to perform a surgical left ventricular restoration. For the past twelve years, it has also been developing a new cardiac catheter ablation method—called a radiofrequency hot balloon catheter—to treat patients with abnormal heart rhythms. This method makes it easier to isolate areas within the heart for treatment, covers more area than other methods, and is easy to use. Trials in Japan have been very successful, and will begin in the U.S. this year.
Along with its specialty, the center offers medical checkups and screenings for colon cancer, cardiac and circulation risk as well as lifestyle diseases. Hayama Heart has several doctors and staff who speak other languages—and plans to add more—and hopes to attract foreign patients, especially from China and other nearby countries.
