Cardiologist — Brussels, Belgium
Dr. Marielle Morissens
Cardiologist trained at ULB since 1995, specialist in adult congenital heart disease and echocardiography.
Since 1995, I have been a cardiologist trained at the Université Libre de Bruxelles.
My expertise covers the full spectrum of cardiac conditions, with a specialization in echocardiography and the management of adult congenital heart disease.
In 2001, I founded the adult congenital heart disease clinic, in partnership with the Hôpital Universitaire des Enfants Reine Fabiola. This initiative aimed to facilitate the transition of young patients from HUDERF to adult cardiology care.
A member of several Belgian and international scientific societies, I notably chaired the Belgian Adult Congenital Heart Disease Group of the Belgian Society of Cardiology.
Alongside my clinical work, I led the cardiology unit at CHU Brugmann, consistently placing patient welfare at the heart of my practice.
In response to increasing specialization in cardiology, I have built an extensive network of expertise.
I practice in both hospital settings and my private practice in Ohain.
In 2025, I joined the cardiology department at Hôpital Erasme to continue my collaboration with HUDERF, now part of the University Hospital of Brussels.
Fully conventioned, I also apply INAMI rates in my private practice in Ohain, in the Brabant Wallon.
My practice is guided by strict adherence to clinical guidelines, continuity of care, and constant availability.
