An 80-year-old woman was admitted to our emergency department with ongoing dyspnea for 2 weeks. The patient was immediately intubated endotracheally because of the hypoxia with flush pulmonary edema. Electrocardiogram showed ST depression and echocardiogram showed hypokinesis of anterior left ventricular wall with poor systolic function. Also her cardiac enzymes were elevated, emergency coronary angiogram was performed from radial artery because both femoral arteries were not fully palpable. Coronary angiogram showed three vessels disease including chronic total occlusion of right coronary artery and left main bifurcation lesion. Also blood flow of left anterior descending coronary artery was delayed. Acute coronary syndrome was the cause of acute heart failure and revascularization was needed but aortography revealed total occlusion of infrarenal aorta. Patient was relatively hemodynamically stable; we planned treating total occlusion of infrarenal aorta with endovascular therapy to maintain a rout for cardiopulmonary support system. With bi-directional approach from both femoral artery and left brachial artery, occlusion site with heavy calcification was finally passed through by guide wire from retrograde approach. After pull-through technique, self-expanding nitinol stent was implanted after pre dilation with small balloon. Considering her EURO score, supposed perioperative mortality was high, percutaneous coronary intervention was performed. A 7 fr sheath was inserted from right femoral artery and intra-aortic balloon pump was inserted from left femoral artery. Sirolimus-eluting stent was implanted to left circumflex artery and also from ostium of left main to mid left anterior descending coronary artery after using an atherectomy device. After successful revascularization, patient became hemodynamically stable and weaning off the respirator was successful. Reporting case achieved successful revascularization to severe coronary artery disease after endovascular recanalization with infrarenal aortic occlusion.
