At the Cardiology Centre Aargau, which is a collaboration between the Hirslanden Klinik Aarau and the Aarau Cantonal Hospital, cardiac specialists and heart surgeons work together closely to provide patients with the highest standard of medical care. Cardiology team meetings are held every week at the Aarau Cantonal Hospital and the patients at the Hirslanden Klinik Aarau are visited daily. Specialised operations such as TAVI (minimally invasive aortic valve replacement using a catheter) are carried out by the cardiologists and heart surgeons at the cardiac catheterisation laboratory at the Hirslanden Klinik Aarau.
