Assist. Prof. Dr. Dimitrios Tsiachris | Medicine | Best Researcher Award

EP and Pacing Lab Director | National and Kapodestrian University of Athens | Greece

Dr. D. L. Tsiachris is a highly accomplished cardiovascular researcher and clinician whose work has profoundly influenced the fields of cardiac electrophysiology and interventional cardiology. With an extensive research portfolio encompassing 224 scientific publications, 4,004 citations, and a Scopus h-index of 34, his contributions have advanced the understanding and management of complex cardiac rhythm disorders. His primary research interests lie in atrial fibrillation, ventricular arrhythmias, catheter ablation, and cardiac resynchronization therapy, with particular emphasis on novel energy-based interventions such as pulsed field ablation, cryoballoon technology, and radiofrequency systems. Dr. Tsiachris possesses exceptional research skills in clinical trial design, data synthesis, systematic reviews, and meta-analysis, enabling him to provide robust evidence supporting safer and more effective therapeutic strategies for patients with structural and electrical heart diseases. His investigations into leadless pacing systems, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, and the optimization of device-based therapies have contributed to personalized and precision-based cardiology. In addition, his studies on patient-reported outcomes and long-term ablation success rates bridge the gap between procedural innovation and patient-centered care. Recognized for his scientific leadership and collaborative excellence, Dr. Tsiachris has co-authored with more than 700 international researchers and continues to influence clinical practice guidelines through his impactful findings. Though his work is primarily published in high-impact journals such as Heart Rhythm, Europace, and Journal of Clinical Medicine, his commitment to advancing cardiovascular science stands as his greatest distinction. Honored for his research excellence and global contributions to electrophysiology, Dr. D. L. Tsiachris remains a driving force in redefining the standards of modern cardiac care through innovation, precision, and evidence-based practice.
