The frequency of using these procedures continuously increased over time. Overall, the prevalence of in\u2010hospital complications was 3.5% (cardiac tamponade, 0.8%; stroke, 0.6%; critical bleeding, 1.9%; mechanical circulatory support, 0.9%; and in\u2010hospital death, 0.8%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The results of this study show the clinical features of VT ablation in a real\u2010world clinical setting.
