1/185. Coronary-subclavian steal associated with severe aortic stenosis treated with combined percutaneous stenting and minimally invasive aortic valve replacement.

    We describe coronary-subclavian steal restricting flow to the left internal mammary artery (LIMA) associated with critical aortic stenosis treated with combined percutaneous transluminal stenting and minimally invasive aortic valve replacement (AVR). An 86-year-old patient had coronary artery bypass graft placement (CABG) seven years prior with the LIMA anastomosed to the left anterior descending coronary artery (LAD). At the time of CABG, the patient had mild aortic stenosis and normal left ventricular function. By the time of re-presentation with refractory angina and heart failure, the patient had developed critical aortic stenosis. Because repeat CABG with median sternotomy risked damaging the LIMA, pre-operative revascularization was planned to minimize the likelihood of peri-operative ischemia. Stenting of the subclavian artery was performed prior to minimally invasive AVR.

2/185. Primary and elective stenting of unprotected isolated left main coronary ostial stenosis in acute coronary syndrome.

    Direct surgical angioplasty or coronary artery bypass graft has been done in patients who have left main coronary ostial stenosis. Recent reports have demonstrated that stenting of unprotected left main coronary artery stenosis has been attempted as an alternative to bypass surgery in selected patients with normal LV function. We report two patients with isolated left main coronary ostial stenosis who are undergoing primary and elective stenting, respectively. Major cardiac events did not occur during a 3-month follow-up. This study suggests that stenting of isolated left main coronary ostial stenosis in acute coronary syndrome is feasible and results in excellent outcomes.

3/185. Electrical neuromodulation for disabling angina pectoris related to isolated stenoses of small epicardial coronary arteries.

    patients with symptomatic small vessel coronary artery disease may be inadequate candidates for revascularization procedures. They may suffer from refractory angina, which does not respond to maximal anti-anginal drug therapy. In addition to patients with end stage coronary artery disease and syndrome X, this newly defined group of subjects with an isolated stenosis of a small coronary artery may benefit from electrical neurostimulation. We describe two patients with intractable angina caused by a significant narrowing of a diagonal branch. This treatment modality should be considered as an alternative method for unsatisfactory revascularization procedures.

4/185. Second generation bifurcation stent: the rapid development of device technology.

    A 57-year-old male with unstable angina and an eccentric 88% diameter stenosis of the left anterior descending artery prior to, and involving the first diagonal branch was treated with the 2nd generation Jomed Sidebranch stent (Jomed, Randingengen, germany). This case outlines the improvements in this novel stent design and demonstrates the rapid advance of device design.

5/185. Stent-supported angioplasty of an ostial left main stenosis following replacement of the ascending aorta with reimplantation of the coronary arteries.

    We describe a patient who underwent replacement of the descending aorta with reimplantation of the coronary arteries for acute type II aortic dissection and developed iatrogenic left main stem stenosis 1 year after operation. The patient was successfully treated by stent implantation in the left main stem.

6/185. Stenting to reverse left ventricular ischemia due to left main coronary artery compression in primary pulmonary hypertension.

    Angina is a common symptom of severe pulmonary hypertension. Although many theories for the source of this pain have been proposed, right ventricular ischemia is the one most commonly accepted as the cause. We report on two patients with primary pulmonary hypertension who had angina with normal activity or on provocation. One patient had severe left ventricular dysfunction. Both were found to have severe ostial stenosis of the left main coronary artery as a result of compression from a dilated pulmonary artery. Both patients underwent stenting of the left main coronary artery with excellent angiographic results, and complete resolution of the signs and symptoms of angina and left ventricular ischemia. Left ventricular ischemia due to compression of the left main coronary artery may be a much more common mechanism of angina and left ventricular dysfunction in patients with pulmonary hypertension than previously acknowledged. Stenting of the coronary artery can be done safely with the resolution of these symptoms.

7/185. Percutaneous revascularization of coexisting severe carotid and coronary artery disease: a case report.

    Following the NASCET and ACAS trials, the use of carotid endarterectomy for the treatment of carotid artery stenosis has become widespread. However, in high-risk patients, the perioperative morbidity and mortality have reached 18%. In such populations, a percutaneous approach including coronary angioplasty and stenting of the carotid lesion could be an option worth exploring. In this report we discuss a case that is representative of our experience with the simultaneous treatment of critical carotid and coronary stenosis. A 74-year-old patient with advanced coronary artery disease and severe bilateral carotid pathology was submitted to coronary angioplasty and stenting of the carotid lesions.

8/185. Stenting unprotected left main coronary artery stenosis in heart transplant patients--the good, bad, and the ugly.

    The major cause of late death following orthotopic heart transplantation is coronary artery vasculopathy. Approximately 50% of heart transplant patients have coronary artery vasculopathy 5 years post-transplantation. With advances in interventional cardiology technology, heart transplant patients with selected lesions are now undergoing intravascular stenting with acute-gain and late-loss rates similar to stenting in non-transplanted patients. We describe 3 consecutive cases of stenting unprotected left main coronary artery disease in orthotropic heart transplant patients. With follow-up to 3 years and no evidence of restenosis, these results suggest that stenting unprotected left main coronary artery lesions in heart transplant patients can be performed with excellent immediate and long-term results.

9/185. Ostial stenosis of coronary arteries after complete replacement of aortic root using gelatin-resorcinol-formaldehyde glue.

    Coronary ostial stenosis between an interposition graft and coronary artery is rare and fatal. A 46-year-old woman who had reconstruction of both coronary arteries using interposition grafts for type A acute dissecting aneurysm presented with acute chest pain. Emergent coronary artery bypass grafting was done with saphenous vein grafts. Inappropriate use of gelatin-resorcinol-formaldehyde glue can be associated with ostial stenosis in the long term. Transesophageal echocardiography is useful to diagnose ostial stenosis of the coronary arteries.

10/185. Negative remodeling at the ostium of the left circumflex artery.

    We report an ostial lesion with negative remodeling. coronary angiography revealed a 60% stenosis at the ostium of the left circumflex artery (LCX). Intravascular ultrasound (IVUS)-guided directional atherectomy followed by stenting was planned. However, IVUS images revealed no significant stenosis and negative remodeling at the ostium of the LCX. The lesion did not undergo intervention.
