Thomas M. Helle-Valle, MD, PhD, Consultant Cardiologist, Rikshospitalet, Oslo University Hospital


Medical doctor and researcher Thomas M. Helle-Valle is a board certified specialist in Internal Medicine and Cardiology from University of Oslo. He was a post-doctoral research fellow at Johns Hopkins Univeristy Hospital, Baltimore in 2008, and received his Ph.D in 2013.


In his Ph.D-thesis “New non-invaisve methods for quantification of myocardial function in the left ventricle”, Helle-Valle introduced and validated new non-invasive methods for detailed assessment of myocardial function. His research demonstrated that new automated pattern recognition algorithms could be applied to echocardiography- or CT recordings to precisely quantify regional and global deformation of the left ventricle. Helle-Valle and colleagues used different models (mathematical simulation, animal experiments and clinical studies) to validate the new analytical methods and demonstrated that the percentage change in myocardial wall deformation (strain) and displacement (rotation) could be used to detect the extent of myocardial ischemia and understand the functional consequences.


Helle-Valle has extensive clinical experience in the use of various echocardiographic modalities and analyses, such as stress-, transesophageal- and intracardiac echocardiography, 4D-imaging and strainanalysis. He is involved in several research projects, particularly regarding atrial function and dyssynchrony, and has a particular responsibility regarding echocardiography during cardiac surgery and percutaneous procedures like MitralClip, TAVI, PTSMA and PFO/ASD/LAA-closure.
