The patient, a 78-year-old woman, presented with sudden chest pain and dyspnea. She had previously undergone coronary artery bypass surgery using SVGs for the three vessels and percutaneous coronary intervention with sirolimuseluting stent placement in the posterolateral branch 13 and 3 years ago, respectively. Electrocardiography revealed ST-segment elevation in leads V1-4, whereas emergent coronary angiography revealed total occlusion in her native coronary arteries. Primary PCI was scheduled. A channel dilator was advanced very smoothly and safely into the distal site of the CTO lesion in the LAD, which showed complete occlusion in the proximal region, via an SVG that was temporally occluded four days earlier. A reverse controlled antegrade and retrograde tracking technique was used to successfully perform percutaneous recanalization. Subsequently, the other two native CTO lesions protected by critically degenerated SVGs were treated with retrograde intervention via the SVGs. The retrograde approach via critically degenerated SVGs is safe, reliable, and fast. If an SVG bypassing the native CTO lesion is critically degenerated, percutaneous coronary intervention should be performed via the SVG.展开更多

We herewith present a case of early TRAS detected 6 hours after a successful renal transplant. Renal angiography showed complete stenosis of the internal iliac to renal artery anastomosis. Percutaneous transplant artery angioplasty was attempted, but was not successful;hence the surgical correction of the same was done. This is to demonstrate the use of saphenous vein bypass of anastomotic obstruction of the previous anastomosis, in case of short renal artery.展开更多

TEE revealed normal size left ventricle with severely dilated left atrium. There was moderate aortic regurgitation and moderate aortic stenosis noted. Patient was incidentally found to have an abnormal vascular communication noted to the right atrium. To further evaluate this f inding, the patient underwent cardiac magnetic resonance angiography which revealed that the tubular structure noted on TEE was actually a graft that was abutting onto the coronary sinus, and the f low anomaly was really the graft coming up and running adjacent to the coronary sinus.展开更多

Peri-operative complications like dissection, stenosis involving coronary artery are well described in many series. We present a rare iatrogenic complication of disrupted left main coronary artery during the delivery of cardioplegia while performing AVR in a 54 year male patient for severe calcific aortic stenosis. The inadvertent injury to the artery was timely noticed and managed successfully with long saphenous vein graft.展开更多
