Department of Clinical Electrophysiology and Electrostimulation @ Ospedale Galeazzi - Sant'Ambrogio

The Clinical Electrophysiology and Electrostimulation Center at Ospedale Galeazzi-Sant'Ambrogio evaluates all arrhythmological issues of cardiac rhythm disturbance through specialist examinations and instrumental tests, pacemaker and automatic defibrillator checks are also performed.

The Center is equipped with highly sophisticated equipment for the diagnosis and treatment of cardiac arrhythmias, and provides:

  • electrophysiological studies;
  • transcatheter ablation interventions for any type of arrhythmia (atrial or ventricular);
  • pacemaker implants (also latest generation Leadless systems);
  • implants of automatic defibrillators (also latest generation subcutaneous systems);
  • implants of biventricular cardiostimulators in patients with congestive heart failure;
  • pacemaker or defibrillator explants with cardiac standby.

This allows both the precise framing of the potentially arrhythmic patient and the assessment of the need for pharmacological treatment or the execution of more sophisticated investigations, up to and including defining the indication for possible admission to the Cardiology department.

24-hour monitoring allows for continuous control of the patient's rhythm, the possibility of checking the effect of antiarrhythmic drug therapies, and postoperative monitoring of transcatheter ablation, together with pacemaker and defibrillator implants.

Ospedale Galeazzi - Sant'Ambrogio

The new hospital brings together in a single facility Istituto Ortopedico Galeazzi, the first hospital for orthopaedic admissions that performs 75% of all revision orthopaedic surgeries in Italy, and Istituto Clinico Sant'Ambrogio, example of healthcare excellence for its cardiovascular unit as well as for the diagnosis and treatment of obesity.

The new Ospedale Galeazzi - Sant’Ambrogio (OGSA), accredited by the Italian National Healthcare System (SSN), and given an IRCCS status (Scientific Institute for Research, Hospitalization and Healthcare) by the Italian Ministry of Health for the study of the locomotor system disorders, it is a center of excellence for clinical and pre-clinical biomedical research, and it is well-known for its teaching activity as a learning site for the Bachelor of Medicine and Surgery in agreement with the University of Milan.

As former Istituto Ortopedico Galeazzi, it is known for its achievements in the field of sports medicine and is now home for RE.GA.IN, a regenerative medicine center for the treatment of cartilage and tendon pathologies.

Since 2007, the Institute has become a member of the ISOC (International Society of Orthopaedic Centers), recognized as one of the 19 institutes of excellence in the field of orthopaedics representing 16 countries.

Former Istituto Clinico Sant'Ambrogio adds to the new OGSA its healthcare excellence in treatment of cardiovascular pathologies with over 500 interventions of cardiac surgery and 2,500 interventional cardiology procedures per year thus becoming among the first Italian centers for cardiovascular treatments. The Cardiothoracic Center represents a point of excellence in mini-invasive cardiac surgery and in the percutaneous aortic valve replacement. Additionally, former Istituto Clinico Sant'Ambrogio is in the first place among the Lombardy hospitals for the treatment of acute myocardial infarction.
