Endoventricular circular patch repair: the "Dor procedure"

Abstract

Although during recent decades the prompt clinical management of myocardial infarction has significantly reduced the incidence of mechanical complications, post-infarction heart failure is still an open issue. The surgical ventricular reconstruction technique, also called the "Dor procedure", was introduced as a surgical strategy to reduce left ventricular volume and restore its shape and function by performing an endoventricular circular patch plasty. Although its use was not clearly beneficial, there is growing evidence from specialized centres suggesting its safety and efficacy, thus bringing this technique back to a leading role in the surgical armamentarium to treat patients with heart failure. The objective of this work was to present a step-by-step explanation of the Dor procedure as a landmark for all surgeons who want to perform it.
