Cardiovasc.

This updated review explores the integration of various imaging techniques, including echocardiography, cardiac magnetic resonance (CMR), multidetector computed tomography (MDCT), electroanatomical mapping (EAM), and nuclear imaging, to optimize VT ablation outcomes. Echocardiography, particularly transthoracic echocardiography (TTE), is an essential first-line tool for evaluating structural heart disease and left ventricular function. Moreover, echocardiography aids in risk stratification and procedural planning by detecting regional wall motion abnormalities and thrombus formation. Meanwhile, intracardiac echocardiography (ICE) enhances ablation precision by providing real-time catheter visualization, improving procedural success, and reducing complications such as cardiac tamponade. Nonetheless, CMR is the gold standard for myocardial tissue characterization, enabling the identification of scar burden and conduction channels critical for VT pathogenesis. Late gadolinium enhancement (LGE) facilitates preprocedural planning by localizing arrhythmogenic substrates, predicting VT recurrence risk, and informing ablation strategies. Additionally, T1- and T2-mapping techniques refine the assessment of myocardial fibrosis and inflammation, further improving patient selection and outcomes. MDCT complements CMR by offering high-resolution anatomical visualization and aids in delineating scar distribution, epicardial fat, and vascular structures, informing safe and effective ablation approaches. The integration of these imaging modalities significantly enhances VT ablation precision, reduces recurrence rates, and improves patient outcomes.<\/jats:p>","DOI":"10.31083\/rcm47045","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T01:28:22Z","timestamp":1785115702000},"source":"Crossref","is-referenced-by-count":0,"title":["The Role of Multimodality Imaging in Guiding Ventricular Tachycardia Ablation: An Updated Review"],"prefix":"10.31083","volume":"27","author":[{"given":"Eiad","family":"Habib","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8016-9049","authenticated-orcid":true,"given":"Mahmoud","family":"Abdelnabi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ramzi","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Kanaan","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hoang Nhat","family":"Pham","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Arizona, Tucson, AZ 85721, USA"},{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Rochester, MN 55902, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmad","family":"Alkhatib","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, MedStar Health, Baltimore, MD 21044, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hesham","family":"Abdalla","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hunter","family":"VanDolah","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Bacon","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Malak","family":"Tahsin","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Creighton University, Phoenix, AZ 85013, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fares","family":"Jamal","sequence":"additional","affiliation":[{"name":"Department of Hematology and Oncology, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulrhman","family":"Eldeib","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, King Faisal Specialist Hospital and Research Center, 12713 Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Arsanjani","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hicham El","family":"Masry","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Mayo Clinic, Phoenix, AZ 85259, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2026,5,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Kuo L, Liang JJ, Nazarian S, Marchlinski FE.
