TPVR was successful in 23 patients (85%). Five serious adverse events occurred in 4 cases (15%), including pulmonary hemorrhage, hypotension requiring vasoactive support, conduit disruption requiring covered stent (n=2), and acute RV dysfunction with flash pulmonary edema. After TPVR, the LVOT peak systolic ejection gradient decreased from median of 35 to 17 mm\u2009Hg (\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001); pulmonary insufficiency was trivial\/none in all but 1 patient, where it was mild. Worsening of systemic RV dysfunction or tricuspid regurgitation was seen in 12 patients (57%) and was associated with a significantly lower post-TPVR LVOT peak systolic ejection gradient (median 17 versus 21 mm\u2009Hg;\n              <jats:italic>P<\/jats:italic>\n              =0.02) and higher post-TPVR RV sphericity index (median 0.88 versus 0.52;\n              <jats:italic>P<\/jats:italic>\n              =0.004).
