However, despite recent technological advancements in the area, serious complications remain, such as blood clot formation, valve leakage, or impaired right ventricular function during the therapy. Limited previous research exists on whether advanced medical imaging techniques can contribute to a better understanding of the cardiac impact during the therapy. Computed tomography (CT) can produce high-quality and time-resolved images of the heart, enabling analysis of both geometry, wall motion, and calculated blood flow. However, until recently, metal artifacts made CT a challenging modality for examining patients with mechanical heart pumps.
Exciting enough, the introduction of photon-counting CT now allows for examinations with reduced metal artifacts, and the overall aim of my research is thus to use this new CT technology to examine the inner geometry, motion, and blood flow of the heart during treatment with mechanical heart pumps. This mapping is expected to enhance current understanding of the treatment and contribute to future development of clinical practice and higher-quality patient care.
