Cost of illness of Heart Valve Diseases (HVDs): A real-world analysis in Italy.

Introduction: Heart valve diseases constitute a significant public health challenge with substantial clinical and economic implications. The ageing population, coupled with advancements in surgical techniques, has led to increased hospitalizations for cardiac valve interventions over the past decade. Despite progress, the economic burden of heart valve diseases remains underexplored, particularly in the context of the Italian healthcare system. This study aims to comprehensively assess the economic burden of heart valve diseases in Italy through a real-world analysis. Methods: Using data from the national Italian Hospital Discharge Records (SDO), we identified the number of adult patients undergoing interventions on the aortic, mitral, and tricuspid valves, along with the associated costs borne by the National Health System. Additionally, we estimated indirect costs by analyzing social security benefit applications related to valve diseases from 2016 to 2019. Results: A notable rise in hospitalizations for cardiac valve interventions, particularly for the aortic (+53.3%) and mitral valves (+29.5%) was revealed through the study period. In-hospital mortality rates declined, reflecting advancements in perioperative care. The economic burden of heart valve diseases in Italy was substantial, with hospitalization costs reaching €808 million in 2018. Social security benefit applications also increased, adding an annual cost of €29 million. Conclusions: Heart valve diseases represent a growing clinical and socio-economic challenge in Italy. This study underscores the imperative for a multidisciplinary approach to effectively manage these conditions. Emphasizing prevention, early diagnosis, and timely interventions is crucial to mitigate the economic impact and enhance the quality of life for patients.
