Cardiac imaging (known as imaging of the heart) is comprised of various modalities. Cardiac imaging include coronary catheterization, echocardiogram, Intravascular ultrasound, Cardiac CT scan and Cardiac MRI. All these are offered by our team of heart specialists in collaboration with the radiology department of the Klinik Hirslanden Clinic nearby:

Cardiac ultrasound (echocardiography): cardiac anatomy, cardiac function

Transthoracic Echocardiography (from outside) :

  • At rest, with or without contrast

  • Under load (medication, physical)

Transesophageal Echocardiography (from the inside):

  • With special 3D technology

  • During interventions / operations on heart

Heart scintigraphy: for cardiac perfusion under stress

Cardiac computed tomography (CT) for coronary arteries, cardiac anatomy

Cardiac magnetic resonance imaging (MRI): cardiac anatomy, cardiac function

  • At rest

  • Under stress ( pharmacological)

Coronary angiography: Presentation coronary vessels / large arteries


Coronary Artery Stenosis


When a blood vessel (coronary artery) on the surface heart becomes blocked, this is called a stenosis. This stenosis can be quantified in a percentage of blockage.  A blockage above 50% is considered significant which leads to underperfusion of the heart muscle and to an infarct.


Aortic Stenosis


Aortic stenosis is a common problem with age. The aortic valve calcifies over time, and the valve, in particular its three cusps which open and close during every cardiac cycle become stiff and calcified which impairs the heart to eject sufficient blood into the body.


Heart Failure


This is a serious condition of the heart which can be caused by several instances which lead to a “weak heart”: infection, congenital, arrhythmia, ischemic or valvular. Heart failure is potentially life-threating and needs to be treated according to the underlying problem (CRT, AICD, Mitraclip, Medication)


Left atrial appendage (LAA closure)


Left atrial appendage closure is a treatment option in patients with atrial fibrillation to close the left atrial appendage from the inside with a “plug” brought in with a catheter through the groin. In addition the left atrial appendage can also be closed surgically from the outside with a “clip” brought through a small hole in the chest (=thoracoscopically).
