The incidence and the clinical course of the disorder have changed dramatically in the last few decades due to improved and fast reperfusion strategies. Despite this decreasing incidence and an improved standard of care, mortality following post-MI VSDs remains high with medical treatment alone. While traditionally post-MI VSDs were only closed surgically, percutaneous closure is a promising treatment strategy that has been introduced with success in recent years.,
