SCD occurs rapidly when sinus rhythm degenerates into ventricular tachycardia (VT) and\/or ventricular fibrillation (VF), followed by asystole. Such progressive worsening of the cardiac rhythm is in most cases observed in the setting of ischemic heart disease and often associated with advanced left ventricular (LV) impairment. Revascularization prevents negative outcomes including SCD and heart failure (HF) due to LV dysfunction (LVD). The implantable cardioverter\u2013defibrillator (ICD) on top of medical therapy is superior to antiarrhythmic drugs for patients with LVD and VT\/VF. The beneficial effects of ICD have been demonstrated in primary prevention of SCD as well. However, yet debated is the temporal management for patients with LVD who are eligible to ICD prior to revascularization, either through percutaneous or surgical approach. Restoration of coronary blood flow has a dramatic impact on adverse LV remodeling, while it requires aggressive long-term antiplatelet therapy, which might increase complication for eventual ICD procedure when percutaneous strategy is pursued; on the other hand, when LV and\/or multiorgan dysfunction is present and coronary artery bypass grafting is chosen, the overall risk is augmented, mostly in HF patients. The aims of this review are to describe the pathophysiologic benefits of revascularization, the studies addressing percutaneous, surgical or no revascularization and ICD implantation, as well as emerging defibrillation strategies for patients deemed at transient risk of SCD and\/or at higher risk for transvenous ICD implantation.<\/jats:p>","DOI":"10.3390\/life13091940","type":"journal-article","created":{"date-parts":[[2023,9,21]],"date-time":"2023-09-21T04:53:05Z","timestamp":1695271985000},"page":"1940","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Revascularization and Left Ventricular Dysfunction for ICD Eligibility"],"prefix":"10.3390","volume":"13","author":[{"given":"Letizia Rosa","family":"Romano","sequence":"first","affiliation":[{"name":"Division of Cardiology, Department of Medical and Surgical Sciences, Magna Graecia University, 88100 Catanzaro, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carmen Anna Maria","family":"Spaccarotella","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Advanced Biomedical Sciences, Federico II University, 80134 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1241-6487","authenticated-orcid":false,"given":"Ciro","family":"Indolfi","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medical and Surgical Sciences, Magna Graecia University, 88100 Catanzaro, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3213-4436","authenticated-orcid":false,"given":"Antonio","family":"Curcio","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Department of Medical and Surgical Sciences, Magna Graecia University, 88100 Catanzaro, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Nageh, M.F., Kim, J.J., Chen, L.-H., and Yao, J.F.
