Abstract
Radiofrequency Ablation of Multiple VTs. Introduction: As treatment options for ventricular tachycardia (VT) continue to evolve, the use of radiofrequency catheter ablation is rapidly expanding. However, in the presence of multiple morphologies of VT, achieving successful results may seem less likely. We report two patients with multiple morphologies of VT who underwent successful radiofrequency ablation by application of adiofrequency energy to a single region in the left ventricle. Methods and Results: Two patients, each without any apparent cardiac dysfunction and a history of documented VT, were referred to our institution for further management. They underwent an electrophysiologic study and were found to have easily inducible VT, of three morphologies in one patient and two in the other. Using a transaortic approach, left ventricular mapping was performed for detecting a site with presystolic potentials, earliest ventricular activation, or both. Application of radiofrequency energy to a single area in the left ventricle resulted in the elimination of all previously inducible VT in each patient. Conclusion: VTs with distinctly different morphologies can occur in patients with no detectable structural heart disease. These VT circuits may share a common pathway and, therefore, may readily be amenable to therapy with radiofrequency catheter ablation.

Introduction: As treatment options for ventricular tachycardia (VT) continue to evolve, the use of radiofrequency catheter ablation is rapidly expanding. However, in the presence of multiple morphologies of VT, achieving successful results may seem less likely. We report two patients with multiple morphologies of VT who underwent successful radiofrequency ablation by application of adiofrequency energy to a single region in the left ventricle. Methods and Results: Two patients, each without any apparent cardiac dysfunction and a history of documented VT, were referred to our institution for further management. They underwent an electrophysiologic study and were found to have easily inducible VT, of three morphologies in one patient and two in the other. Using a transaortic approach, left ventricular mapping was performed for detecting a site with presystolic potentials, earliest ventricular activation, or both. Application of radiofrequency energy to a single area in the left ventricle resulted in the elimination of all previously inducible VT in each patient. Conclusion: VTs with distinctly different morphologies can occur in patients with no detectable structural heart disease. These VT circuits may share a common pathway and, therefore, may readily be amenable to therapy with radiofrequency catheter ablation.</abstract><subject lang="en"><genre>Keywords</genre><topic>radiofrequency catheter ablation</topic><topic>ventricular tachycardia</topic><topic>multiple morphologies</topic></subject><relatedItem type="host"><titleInfo><title>Journal of Cardiovascular Electrophysiology</title></titleInfo><genre type="Journal">journal</genre><identifier type="ISSN">1045-3873</identifier><identifier type="eISSN">1540-8167</identifier><identifier type="DOI">10.1111/(ISSN)1540-8167</identifier><identifier type="PublisherID">JCE</identifier><part><date>1995</date><detail type="volume"><caption>vol.</caption><number>6</number></detail><detail type="issue"><caption>no.</caption><number>11</number></detail><extent unit="pages"><start>1015</start><end>1022</end><total>8</total></extent></part></relatedItem><identifier type="istex">01662D92CBD281C364F28F3D29CFD64E97ABB886</identifier><identifier type="DOI">10.1111/j.1540-8167.1995.tb00378.x</identifier><identifier type="ArticleID">JCE1015</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
