Sebastian Sarvari, MD, PhD, Consultant Cardiologist, Department of Cardiology, Rikshospitalet, Oslo University Hospital.

He defended his PhD thesis titled "Detection of subtle myocardial alterations by echocardiographic techniques for improved prognostic information in patients with heart disease." in September 2013. Sarvari's main supervisor was Professor Thor Edvardsen, MD, PhD.

Sarvari showed that new ultrasound methods can detect cardiac function at a very early stage in different patient groups.

Sudden cardiac death due to arrhythmia is one of the most common causes of death in the Western world and in younger is often caused by hereditary heart disease. A new ultrasound method can predict which patients are going to get serious heart rhythm abnormalities. The thesis examined patients with arrhythmogenic right ventricular cardiomyopathy. The disease is one of the most common hereditary disorders that lead to sudden cardiac death. The study shows that irregular cardiac contractility measured by the new method is a risk marker of cardiovascular arrhythmia. The method improves the selection of patients with high risk of death so that these can be fitted with a defibrillator.
