Since 1929 various surgical procedures have been devised to revascularize the ischemic heart to provide it with blood from extracoronary sources. A comparative study has been carried out in 80 mongrel dogs over a two-year period to evaluate the relative merits of cardio-omentopexy, left atrial pulmonary artery anastomosis and the Ivalon sponge operation. The Ivalon sponge procedure proved to be most effective in relieving artificially produced myocardial ischemia. The procedure has subsequently been carried out in two patients with crippling angina pectoris, and a complete relief of symptoms has been achieved in both.
自1929年以来，人们设计了各种外科手术来使缺血心脏重新血管化，以便从冠状动脉外的来源为其供血。在两年时间里，对80只杂种狗进行了一项比较研究，以评估心脏大网膜固定术、左心房肺动脉吻合术和伊瓦龙海绵手术的相对优点。结果证明，伊瓦龙海绵手术在缓解人为造成的心肌缺血方面最为有效。随后，该手术在两名患有严重心绞痛的患者身上实施，两名患者的症状均得到了完全缓解。
