The crista terminalis (CT) region lies close to the right phrenic nerve and may exhibit anisotropic conduction and native or functional conduction block, while also serving as a potential non\u2010pulmonary\u2010vein trigger site. We evaluated the acute feasibility and electroanatomic endpoint of the Crista Caval Line (CCL), a CT\u2010guided, sinoatrial node (SN)\u2013sparing lesion set created with lattice\u2010tip pulsed field ablation (PFA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p>We prospectively enrolled 36 consecutive patients undergoing CCL creation during repeat AF ablation or ablation for non\u2010paroxysmal AF. Pre\u2010CCL sinus\u2010rhythm high\u2010density right atrial activation mapping was performed in all patients. CT\u2010related conduction delay or block was observed in 27 patients (75.0%). In 14 patients (38.9%) with an apparent CT block line, the inferior application\u2010set edge was aligned to the block line; in the remaining 22 patients without an apparent block, placement was primarily guided by intracardiac echocardiography. The CCL was positioned posterior to the CT, with the lateral margin of its superior application set kept approximately 15\u2009mm posterolateral to the earliest mapped sinus activation site for SN protection. The CCL measured 78.8 [66.4\u201386.0]\u2009mm from first to last tag and required 26 [22\u201330] PFA applications over 370 [282\u2013481]\u2009s. First\u2010pass bidirectional transverse conduction block was confirmed in all patients by postablation activation mapping and differential pacing from both sides of the CCL. Next\u2010day inspiratory\/expiratory chest radiography showed no abnormality suggestive of phrenic nerve palsy; no pacemaker\u2010requiring SN dysfunction or other clinically apparent collateral injury occurred.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A CT\u2010guided, SN\u2010sparing CCL can be reproducibly created with lattice\u2010tip PFA, producing a first\u2010pass bidirectional transverse conduction block without clinically apparent phrenic nerve palsy.
