Modern cardiothoracic surgery provides some of the most innovative treatment options for patients suffering from severe and end stage cardiovascular and respiratory disease, including mechanical assist and heart-lung transplantation. Despite major progress, these invasive surgeries represent some of the most invasive insults to humans and are associated with high perioperative complication rates, disability, severe morbidity and mortality.

This research is dedicated to better understanding the fundamental mechanisms involved in these complications and translating mechanistic insights into sophisticated diagnostics in real time at the bedside. We are also committed to improving outcomes by assessing our patient care locally and on a global international scale and by evaluating novel therapeutic options and by building international consensus towards the highest quality of care.

We are focusing on two principle mechanistic areas namely the surgical inflammatory response and the consequent metabolic disequilibrium. Translating these alterations, we are conducting biomarker research with major interest in perioperative exhaled breath analysis, especially methods suitable for deployment into the operating room and intensive care unit with real time data acquisition. In the therapeutic domains we are improving ventilation practices, modulating surgical inflammation by novel cytokine absorption therapy, optimising metabolism by inhaled nitric oxide and improving transplantation by revolutionary ex vivo platforms.

Our activities are recognised internationally. By appointments into leading roles at the European Association of Cardiothoracic Anaesthetists and the International Association for Breath Research, we are improving patient care by leading position statements and multisociety clinical consensus guidelines.
