Abstract
Background: as transcatheter technologies have advanced, the patient population that is referred to open heart surgeries has shifted. This study’s objective was to evaluate recent trends in the characteristics of patients undergo surgical valvular interventions and coronary revascularizations (CABG) in our center over a period of 14 years. Methods: this is a retrospective analysis of ecological trends in the age, sex, and risk profile (Charlson comorbidity index—CCI) of patients who, from January 2010 to December 2023, underwent CABG, aortic valve replacement (AVR), or mitral valve repair or replacement (with or without tricuspid valve intervention). The data were extracted from electronic clinical files using MD-Clone software. Results: for the CABG procedures, the respective data for 2010 and 2023 were: mean ages 68.0 and 64.6 years; 79.7% and 83.1% males; and mean CCI scores 3.16 and 2.51. The p-values for the cumulative differences over the study period were 0.001, 0.005, and 0.013, respectively. The respective data for isolated AVR were mean ages of 69.2 and 62.9 years; 64.1% and 59.1% males; mean CCI 3.64 and 2.32; p-values: p-values: 0.84, 0.422, and 0.318. Conclusions: over a 14-year period, changes were evident in the age, sex distribution, and CCI for operations performed in our center. These changes most likely resulted from accumulated data regarding the advantages and detriments of treatment strategies, mostly of CABG vs. percutaneous coronary intervention; major advancements in transcatheter technologies, mostly in transcatheter AVR; and clinical guidelines facilitating a more collaborative decision-making, open-minded, and personalized approach.
