Show all keywords - [Heart and Lung Center](< /en/search?q=Heart and Lung Center >) The Cardiac Unit at Meilahti Tower Hospital is a treatment unit that performs both invasive and non-invasive diagnostic and therapeutic procedures. Our unit has facilities in four hospitals: Meilahti, Jorvi, Peijas and Hyvinkää. The Meilahti Cardiac Unit is the largest and most extensive of our units. There are six treatment rooms for invasive procedures, two rooms for echocardiography, and one room for gamma imaging. Thanks to its cardiological emergency services, the unit is prepared for operations around the clock. The unit does not have beds for overnight stays. ## The most common invasive operations include: - coronary artery angiography - coronary balloon angioplasty - catheterization examination of valve defects - pacemaker implantation - catheterization examination and treatment of arrhythmia - myocardial biopsies. ## In addition, our non-invasive examinations include: - echocardiography - cardiac perfusion scans with a gamma camera. You will primarily arrive at the unit for treatment after being assessed by specialists in the outpatient clinics, cardiological units, coronary care units, or other hospitals or departments in Southern Finland. A significant proportion of examinations are implemented on an outpatient basis. We kindly ask that patients arrive to the cardiac unit with an escort only if it is necessary. **Patients’ escorts cannot stay in our unit before or during the procedure.** We train future health care professionals in our unit. We hope that you will allow students to participate in your care. Consenting or refusing student participation will not affect your care. ## [ Maisa Portal (opens in new window, links to another website) ](https://www.maisa.fi/maisa/Authentication/Login?lang=britishenglish) Maisa.fi You can use our online services by signing in to the Maisa Portal.
