Alexander Maass


Alexander Maass has been trained in Würzburg/Germany as Internist, Cardiologist and Clinical Electrophysiologist. Since May 2006, dr. Maass works as Cardiologist and Director of the Cardiac Device Program in the University Medical Centre Groningen, The Netherlands. In 2016, he became Deputy Director of the Cardiology Training program and since September 2019, he is fully responsible for training young doctors to become cardiologists.

Current activities

His research focus is on optimization of cardiac device implantation and programming. He has participitated as an investigator in several landmark device studies and is member of the critical event committee of several ongoing landmark device studies. He is supervising students on several investigator-initiated studies to improve delivery of pacemakers and implantable cardioverter-defibrillators with the main focus on cardiac resynchronisation therapy.

Reappraisal of Atrial Fibrillation: Interaction between hyperCoagulability, Electrical remodeling, and Vascular Destabilisation in the Progression of AF

My publications

Heart failure with preserved ejection fraction, atrial fibrillation, and the role of senile amyloidosis.

Heart failure with preserved ejection fraction and AF are very common diseases that also often occur in combination, further aggravating each other. Senile amyloidosis, either due to TTR (ATTRwt) or ANP (IAA) appears to play an important role in both diseases and in their interaction. In terms of diagnostics, bone scintigraphy has become available and affords an easy and reliable way to establish the presence of cardiac ATTRwt. Moreover, pharmacological options are now available or under development to treat ATTRwt and possibly also IAA, thereby potentially stopping, or even reversing, the downhill course of some patients with HFpEF and AF.
