The aim of our study is to report our experience with this option and to discuss its advantages and disadvantages.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods and Results\u2014<\/jats:title>\n            <jats:p>\n              In our center from 1983 to 2010, 4221 patients underwent diagnostic EMB. In particular, 2396 (56.8%) underwent biventricular EMB, 1153 (27.3%) underwent selective LVEMB, and 672 (15.9%) underwent selective RVEMB. The rate of complications and histological findings were retrospectively analyzed. The periprocedural major complication rate (perforation with or without cardiac tamponade, embolization) was 0.33% for LVEMB and 0.45% for RVEMB, with a significant decrease in the rate of major complications with time (from 1.6% and 1.9% in 1983\u20131988 to 0% and 0.3% in 2007\u20132013, respectively;\n              <jats:italic>P<\/jats:italic>\n              &lt;0.001 for both), denoting a steep learning curve. No patients died. When the structural and functional abnormalities affected exclusively the LV, the diagnostic yield of LVEMB was 97.8% compared with 53% for RVEMB. Conversely, when the echocardiographic presence of increased wall thickness, local or global ventricular dilation, or dysfunction also involved the RV, the diagnosis was reached in 98.1% of LVEMBs and 96.5% of RVEMBs. This discrepancy was particularly evident for myocarditis, whereas in infiltrative and storage diseases, the histological abnormalities were always detectable in both ventricles.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>LVEMB is a safe procedure with very low transient complications, comparable to RVEMB.
