Centres for Cardiology

The specialist fields of angiology and cardiology cover all disorders of the cardiovascular system.

Treatment options

This includes the threat of heart attack and stroke, peripheral arterial occlusive disease, renal artery stenosis and the treatment of the corresponding risk factors (high blood pressure, high cholesterol, diabetes, smoking) as well as cardiac arrhythmia, heart valve changes, heart failure, aneurysms, thrombosis, pulmonary embolism, varicose vein disorders and oedema of various origins.

In addition to comprehensive assessments and tailored medical treatments, we also offer interventions using catheter technology (balloon therapy, stent implantation, minimally invasive aneurysm treatment). If necessary for our patients, we work with vascular surgeons, cardiac surgeons and rhythmologists.

Our centres



The HerzGefässKlinik is run by Dr Gabor Sütsch (specialising in interventional and non-interventional cardiology) and Dr Anders J. Leu (specialising in interventional and non-interventional angiology) and their team deals with acute complications such as heart attack and persistent problems such as arrhythmia or conduction disorders – from assessments to appropriate treatment. 

Dr Silviana Spring also treats patients with angiological vascular diseases at the HerzGefässKlinik.

Holistic examinations and treatments of the central and peripheral cardiovascular systems are also carried out. The modern cardiac catheter laboratory, which opened in 2019, features cutting-edge technology, ensuring that all examinations and treatments are always carried out at the highest level. Comprehensive internal medical treatment is also offered for both inpatients and outpatients.
