Multielectrode mapping catheters (MEMC) allow the performance of high resolution and density maps but the utility of these catheters in ventricular tachycardia (VT) ablation procedures has not been yet widely described. We sought to evaluate the utility of a MEMC during scar‐related VT ablation procedures.
Methods
Eighty‐five consecutive scar‐related VT ablation procedures were performed in 81 patients. In the first 26 procedures, a standard 3.5‐mm tip linear catheter was employed for endocardial/epicardial mapping (control group). In the following 59 procedures mapping was performed with a MEMC (study group). Procedural time, LV endocardial and epicardial mapping time, complications and ablation outcomes were compared.
Results
The use of the MEMC resulted in a significant shortening of the endocardial and epicardial mapping times (38 ± 15 minutes vs. 56 ± 24 minutes for endocardial LV mapping in the study and control group, respectively, P = 0.001; and 28 ± 9 minutes vs 41 ± 16 minutes, for epicardial mapping, P = 0.011) as well as the total procedural time (177 ± 53 minutes vs. 206 ± 50 minutes, respectively, P = 0.02). The mapping density was also significantly increased in the study group (mean endocardial LV points: 2,143 ± 1,419 vs. 485 ± 174, for the study and control group, respectively, P |

The mapping density was also significantly increased in the study group (mean endocardial LV points: 2,143 ± 1,419 vs. 485 ± 174, for the study and control group, respectively, P < 0.0001), specially within the scar area (49.6 ± 34 points/cm2 vs. 8.4 ± 4.6 points/cm2, P < 0.001). No differences in acute and long‐term follow‐up outcomes were observed.
Conclusions
High‐density multielectrode mapping is associated with a significant reduction of procedural and mapping times and a significant increase of mapping density without affecting outcomes in patients with scar‐related VT.</description><identifier>ISSN: 1045-3873</identifier><identifier>EISSN: 1540-8167</identifier><identifier>DOI: 10.1111/jce.13302</identifier><identifier>PMID: 28744991</identifier><language>eng</language><publisher>United States: Wiley Subscription Services, Inc</publisher><subject>Ablation ; Aged ; Cardiac arrhythmia ; catheter ablation ; Catheter Ablation - trends ; Catheters ; Cicatrix - diagnostic imaging ; Cicatrix - physiopathology ; Cicatrix - surgery ; Complications ; Density ; Electrodes ; Epicardial Mapping - trends ; Epicardial Mapping - utilization ; Female ; Group dynamics ; Humans ; ischemic cardiomyopathy ; Male ; Mapping ; Medical instruments ; Middle Aged ; multielectrode mapping ; PentaRay® catheter ; Prospective Studies ; Tachycardia ; Tachycardia, Ventricular - diagnostic imaging ; Tachycardia, Ventricular - physiopathology ; Tachycardia, Ventricular - surgery ; Ventricle ; ventricular tachycardia</subject><ispartof>Journal of cardiovascular electrophysiology, 2017-11, Vol.28 (11), p.1306-1315</ispartof><rights>2017 Wiley Periodicals, Inc.</rights><rights>Journal compilation © 2017 Wiley Periodicals, Inc.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3532-d727319fb4730334c3e6f34d1618f9dd8e85571d2c79c970c5d9db2d3377796d3</citedby><cites>FETCH-LOGICAL-c3532-d727319fb4730334c3e6f34d1618f9dd8e85571d2c79c970c5d9db2d3377796d3</cites><orcidid>0000-0001-6783-0138</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fjce.13302$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fjce.13302$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>314,776,780,1411,27901,27902,45550,45551</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/28744991$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Cano, Óscar</creatorcontrib><creatorcontrib>Plaza, Diego</creatorcontrib><creatorcontrib>Saurí, Assumpció</creatorcontrib><creatorcontrib>Osca, Joaquín</creatorcontrib><creatorcontrib>Alonso, Pau</creatorcontrib><creatorcontrib>Andrés, Ana</creatorcontrib><creatorcontrib>Sancho‐Tello, María‐José</creatorcontrib><creatorcontrib>Martínez‐Dolz, Luis</creatorcontrib><title>Utility of high density multielectrode mapping during ablation of scar‐related ventricular tachycardia</title><title>Journal of cardiovascular electrophysiology</title><addtitle>J Cardiovasc Electrophysiol</addtitle><description>Introduction
