In this study, we sought to retrospectively analyze the long\u2010term outcomes of CSD in patients with refractory VT and\/or VT storm with a majority of the patients being taken up for CSD ahead of CA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We included consecutive patients with SHD who underwent CBD from 2010 to 2019 owing to refractory VT.

The underlying VT substrate was ischemic heart disease (IHD) in 30 (46.2%) patients while the remaining 35 (53.8%) patients had other nonischemic causes. The mean duration of follow\u2010up was 27\u2009\u00b1\u200924 months. A complete response to CSD was achieved in 47 (72.3%) patients. There was a significant decline in the number of implantable cardioverter\u2010defibrillator (ICD) or external defibrillator shocks post\u2010CSD (24\u2009\u00b1\u200937 vs. 2\u2009\u00b1\u20094, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.01).
