Preoperative and 6\u2010month postoperative biochemical and cardiovascular evaluations, including echocardiography, were performed.

Echocardiographic evaluations significantly improved diastolic parameters, including E velocity (cm\/s) and E\/A(atrial) ratio. Systolic dysfunction also showed significant improvement on conventional echocardiography and STE, as evidenced by reduced left ventricular (LV) mass, ejection fraction (EF), and postoperative GLS. Although a relative drop in EF was noted postprocedure, STE findings suggested a significant improvement in systolic dysfunction, signifying GLS as a more appropriate means of assessing systolic dysfunction. Serum PTH demonstrated a strong positive correlation (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u20090.638,\n
