摘 要：Objective Catheter-based pulmonary vein isolation(PVI) is an established therapy to treat patients with paroxysmal atrial *** high-density mesh mapper(HDMM),a novel multi-electrode circumferential mapping catheter,guides the circumferential atrium isolation without help of 3D electro-anatomic *** compared the difference of the circumferential pulmonary vein anatomy mapping guided between by Carto system(one 3D electro-anatomic mapping system) and by HDMM. Methods From August 2010 to February 2012,forty-four consecutive patients with paroxysmal atrial fibrillation were scheduled for a first procedure of PVI.A circumferential PV ostial anatomy map was set up in Carto system around the HDMM(HDMM,Bard Electrophysiology) firstly,while the operator was blinded to the Carto ***-guided PVI was performed in every patient by irrigated radiofrequency application,which established another circumferential PV(CPV) ostial anatomy *** study compared the difference between the two images,including the point-to-point straight distance,the area,the perimeter and so on. Results All 176 PVs in 44 patients could be mapped by the HDMM and *** 43.2%of the PV ostial anatomies were matched very well between the two different map *** point-to-point straight distance between the HDMM-guided map and Carto-guided map is(6.20±1.44)*** distance in some PV segments between the two images is *** area of circumferential right PV(CRPV) in the two views is 8.41±2.88mm in Carto map,9.37±1.84 mm in HDMM map respectively(P=0.013). The area of circumferential left PV(CLPV) is(8.12±2.48)mm in Carto,(8.98±2.33) mm in HDMM respectively(P=0.071).The CRPV perimeter in Carto and HDMM is(11.63±1.95)mm vs (11.87±1.72)mm(P=0.471),the CLPV(11.29±1.59)mm vs(11.12±1.71)mm(P=0.573). Conclusion Compared to the Carto-guided CPV anatomy image,the HDMM-guided one still has some discrepancies,which maybe explain a part of reasons why the high-density mesh ablator(
