In 2025, our department performed surgery on 821 patients, including 675 cases of open-heart surgery with cardiopulmonary bypass and thoracoabdominal aortic surgery, 101 cases of peripheral artery surgery, and numerous cases of varicose vein surgery. In terms of surgical techniques, we performed 67 cases of coronary artery bypass surgery, 304 cases of valve repair/replacement, and 238 cases of thoracoabdominal aortic artificial blood vessel replacement or stent graft placement, demonstrating a comprehensive range of procedures for representative diseases. Tokai University Hospital is a facility that actively provides advanced emergency medical care, and more than 30% of our aortic and peripheral vascular surgeries are emergency surgeries. In addition, we treat more than 70 cases of acute aortic dissection annually, including patients who received conservative treatment, and many of these patients were transferred by ambulance from hospitals in the Seisho region. Our areas of particular focus include left ventricular reconstruction, such as the Dor procedure for ischemic cardiomyopathy (over 100 cases performed since 2002), aortic valve replacement with preservation of the aortic valve for aortic root dilation (over 50 cases performed), mitral valve repair (90% of mitral valve surgeries performed), Maze procedure for atrial fibrillation (43 cases in 2025), and stent graft placement for aortic aneurysms (63 cases in 2025). Since 2011, we have had two cardiopulmonary bypass machines in parallel, and since 2017, we have had access to a hybrid operating room, enabling not only hybrid surgeries but also emergency responses during scheduled surgeries. We also perform minimally invasive cardiac surgery (MICS) if requested by the patient. We believe this will allow us to make a further contribution to regional healthcare.
