Background-There are limited data on typical arrhythmogenic substrates and associated ventricular tachycardias (VT) in patients with nonischemic cardiomyopathy. The substrate location may have implications for the ablation strategy. Methods and Results-Nineteen consecutive patients with nonischemic cardiomyopathy (age 58±14 years, 79% men, left ventricular ejection fraction 41±11%) who underwent contrast-enhanced MRI and VT ablation were included. On the basis of 3-dimensional contrast-enhanced MRI-derived scar reconstructions, 8 patients (42%) had predominant basal anteroseptal scar, 9 patients (47%) had predominant inferolateral scar, and 2 patients (11%) had other scar types. Three distinct VT morphologies (≥1 of 3 inducible in 16/19 patients) were associated with underlying scar type. In 9 patients with anteroseptal scar-related VT (8/9 predominant scar, 1/9 nonpredominant), ablation target sites (defined as sites with ≥11/12 pacemap, concealed entrainment or VT termination during ablation) were located in the aortic root and/or anteroseptal left ventricular endocardium in 8 patients (89%) and in the anterior cardiac vein in 1 patient (11%), with additional target sites at the right ventricular septum in 2 patients (22%) and at the epicardium in 1 patient (11%). In contrast, in 8 patients with predominant inferolateral scar-related VT, target sites were located at the epicardium in 5 patients (63%) and in the endocardial inferolateral left ventricle in 3 patients (37%). Conclusions-Two typical scar patterns (anteroseptal and inferolateral) account for 89% of arrhythmogenic substrates in patients with nonischemic cardiomyopathy. Three distinct VT morphologies are highly suggestive of the presence of these scars. Anteroseptal scars were, in general, most effectively approached from the aortic root or anteroseptal left ventricular endocardium, whereas inferolateral scars frequently required an epicardial approach.

SAŽETAK: Kardiomiopatije su bolesti miokarda koje se ne mogu objasniti abnormalnim uvjetima punjenja niti promjenama koronarnih arterija. One se klasifi ciraju u više morfoloških i funkcionalnih fenotipova čiji uzrok mogu biti genetički i negenetički mehanizmi. Dominantne teme u radovima objavljenima u razdoblju 2012.-2013. slične su onima navedenima u Almanahu 2011.: uporaba (i interpretacija) genetskog testiranja, razvoj i primjena novih neinvazivnih tehnika slikovne dijagnostike te uporaba serumskih biomarkera u procesu dijagnoze i za prognozu. Važna inovacija od posljednjeg Almanaha jest razvoj sofi sticiranijih modela za predviđanje neželjenih kliničkih događaja. SUMMARY:Cardiomyopathies are myocardial disorders that are not explained by abnormal loading conditions and coronary artery disease. They are classifi ed into a number of morphological and functional phenotypes that can be caused by genetic and non-genetic mechanisms. The dominant themes in papers published in 2012-2013 are similar to those reported in Almanac 2011, namely, the use (and interpretation) of genetic testing, development and application of novel non-invasive imaging techniques and use of serum biomarkers for diagnosis and prognosis. An important innovation since the last Almanac is the development of more sophisticated models for predicting adverse clinical events.CITATION: Cardiol Croat. 2014;9(11-12):543-557. | DOI: http://dx
