Patient demographics, procedural details, and yearly echocardiographic findings were collected and compared as appropriate. The risk of IE was compared between groups defined by baseline characteristics using time\u2010to\u2010event methods. Joint modeling was used to evaluate the association between peak\u2010to\u2010peak gradient trajectories over time and the risk of IE. The predictive performance of using peak\u2010to\u2010peak gradient thresholds to predict IE was evaluated using receiver operating characteristic (ROC) analyses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>\n                      A total of 226 patients underwent successful TPVR of which 26 patients developed IE. The annualized incidence of IE was 2.96 per 100 patient years. Patients with and without IE had similar ages, weights, and diagnoses. All IE cases were with the Melody valves. Patients who had higher postimplantation echo\u2010derived peak instantaneous gradients (PGs) were significantly more likely to develop IE. Patients with immediate postimplant invasive peak to peak gradient \u2265\u200915\u2009mmHg were more likely to develop IE. Higher PGs over time were significantly associated with a higher risk of IE (HR 1.04 per mmHg; 95% CI: 1.00\u22121.07,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.03).

Patients who ultimately developed IE trended to have higher PPG post\u2010TPVR and higher gradients over time before the development of IE. The rate of change of echo\u2010derived gradients in patients with lower initial invasive gradients was more pronounced. These findings suggest that longitudinal monitoring of echocardiographic gradient could provide targeted surveillance in those identified at higher risk for IE.<\/jats:p>\n
