The membrane was crossed by needle re-entry and divided with an electrified through-and-through guidewire at 40-60 W under fluoroscopy, without routine intravascular ultrasound or image fusion. A perfused-lumen index (perfused lumen divided by total aortic diameter) was measured before and after the procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Septotomy was performed in 20 of 21 patients (technical success 95% on an intention-to-treat basis). Indications were landing-zone preparation (57%), malperfusion (33%), preparation for open repair, and true-lumen collapse. Malperfusion resolved in all 7 patients treated for that indication, and the perfused-lumen index rose from a median of 0.16 to 0.98 (18 patients, P\u2009&amp;lt;\u2009.001). There was no stroke, spinal cord ischaemia, or retrograde type A dissection. Thirty-day, in-hospital, and overall mortality were 10%, 14%, and 19%, respectively, with 1 fatal delayed aortic rupture and no intraprocedural death. Three unplanned reinterventions occurred; median follow-up was 5.1 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Electrosurgical septotomy was feasible across the full spectrum of aortic dissection and, in selected patients, as stand-alone treatment for malperfusion, using standard electrosurgical equipment.
