Yet, for adults with congenital heart disease (ACHD), the role of sHPT and the factors contributing to its development remain poorly understood.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>This cross-sectional, single-centre study assessed the prevalence of sHPT in 754 patients with ACHD.

SHPT was more common in patients with univentricular physiology (29.6%) than biventricular physiology (13.3%) (P &amp;lt; 0.001). In multivariate analysis, glomerular filtration rate (P &amp;lt; 0.001), serum 25-hydroxyvitamin D\u2083 (P = 0.004), use of loop diuretics (P = 0.001), oxygen saturation (P = 0.03), and liver stiffness (P = 0.033) were independently associated with sHPT. Among patients with biventricular physiology, right ventricular free wall longitudinal strain (P = 0.028)\u2014rather than left ventricular global longitudinal strain\u2014showed a significant
