Right ventricular dysfunction (RVD) is a marker of advanced disease and poor prognosis; however, its clinical impact and reversibility after TAVI remain unclear. Insulinlike growth factor binding protein\u20107 (IGFBP\u20107), a biomarker associated with endothelial function and myocardial stress, has been linked to heart failure and adverse cardiovascular outcomes. This prospective study aimed to evaluate changes in right ventricular function after TAVI and to investigate the relationship between IGFBP\u20107 levels and clinical, echocardiographic, and laboratory parameters during follow up. Our findings may provide insight into right ventricular recovery after TAVI and the potential prognostic role of IGFBP\u20107 in this setting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Demographic data (age, gender, height, weight), basic echocardiographic parameters and routine blood laboratory tests of patients who applied to our clinic and underwent TAVI due to severe AS were recorded before TAVI and at 48\u00a0h and 6 months after the procedure. A prospective study was designed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study included 116 individuals, 76 (65.5%) of whom were patients and 40 (34.5%) were controls. Both groups had similar age and gender characteristics. It was shown that there was improvement in the parameters indicating right ventricular function (PAP, RVSM and TAPSE) measured in the preoperative period at the postoperative 48th hour and at the postoperative sixth month follow\u2010up after TAVI. IGFBP\u20107 level was higher in the preoperative patient group compared to the postoperative sixth month follow\u2010up. It was found that IGFBP\u20107 levels showed positive correlations with proBNP, CRP, left atrial volume index (LAVI) and negative correlations with EF Simpson and EGFR at the postoperative sixth month follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study shows that TAVI not only relieves anatomic obstruction but also may contribute to improving right ventricular functions, valve insufficiency degrees, and systemic biomarker levels. IGFBP\u20107 was found to be significantly associated with both cardiac (proBNP, EF, LAVI) and renal (eGFR) functions, suggesting that this marker may be a biomarker reflecting multisystem organ effects. Further studies with larger patient groups and long term follow up will contribute to the validation of these findings and their integration into clinical practice.<\/jats:p>\n
