Clinical and experimental cardiovascular monitoring

The research profile is to test and develop new technologies in perioperative patient monitoring.

This involves evaluating circulatory effects of new therapies, such as minimally invasive image-guided treatment of aortic stenosis (TAVI) and laparoscopic surgery and radiofrequency ablation for the treatment of liver metastases.

We also test miniaturized sensors and artificial intelligence for monitoring mechanical circulation support (ECMO and LVAD) in the treatment of heart and lung failure.

Long-term goals

The long-term goal of the research group is to transfer new technologies and new concepts in physiology to clinical practice.

Treatment trends

Trends in the treatment of various heart diseases increasingly involve the use of minimally invasive techniques and procedures, such as PCI for coronary artery disease, TAVI for aortic stenosis, treatment of severe heart failure with CRT.

Another trend is more and more use of advanced mechanical circulatory devices such as ECMO and LVAD as part of the treatment of life-threatening heart failure.

Although a method is classified as minimal invasive, the procedure can still involve high risk for the patient, for instant cardiac tamponade in TAVI. Unlike TAVI, LVAD implantation is a very invasive procedure.

In both cases, assessment of cardiovascular status is important, but requires different approaches and must be adapted to the invasiveness of the procedure.

New methods

We test new methods for monitoring perioperative cardiovascular status. This includes non-invasive cardiac ultrasound, new sensor technologies and signal processing methods on vital signs. The purpose is to detect and predict complications and thus be able to optimize the treatment.

An object in our research is that novel monitoring modalities should also be applicable in circulatory unstable patients in the intensive care unit, such as patients with septic shock and patients treated after cardiac arrest.
