We describe a case of stenting an unprotected left main coronary artery stenosis in an octogenarian patient with cardiogenic shock complicating acute myocardial infarction. Our patient had no in-stent restenosis of the left main for three years and remains asymptomatic. Since, in the octogenarian patient, the surgical risk for emergent coronary artery bypass graft is extremely high, coronary artery stenting of the unprotected left main for myocardial infarction complicated by cardiogenic shock is an alternative treatment in selected patients.

Case Reports
Late clinical presentation of femoral artery occlusion after deployment of the angio-seal closure device.
We report a case of late femoral artery thrombosis after deployment of the Angio-Seal closure device. The unusual late clinical presentation, aggressive anticoagulation which likely delayed clinical symptoms and the challenging surgical findings are discussed. Physicians need to be alert for possible complications arising late after deployment of closure devices and vascular surgeons must be familiar with the design of these devices since they may be required to repair a variety of arterial injuries associated with their use.

Myocardial infarction is a rare complication that can occur immediately after a blunt chest trauma. We report a 36-year-old male who experienced a fatal anterolateral myocardial infarction after a nonpenetrating chest injury sustained in a car accident. Injuries of the coronary arteries associated with blunt chest trauma predominantly affect the left anterior descending artery. This is the first case of traumatic complete occlusion of the left main coronary artery (LMCA) demonstrated by coronary angiography.

Case Reports
Successful stent treatment of pulmonary vein stenosis following atrial fibrillation radiofrequency ablation.
Pulmonary vein stenosis is a known complication of radiofrequency ablation of atrial fibrillation foci. We report a case of severe unilateral pulmonary vein stenosis following radiofrequency ablation resulting in no perfusion to the right lung. Simple balloon dilation was unsuccessful in this patient. Stent placement in the stenotic right pulmonary veins resulted in reperfusion of the lung as documented by follow-up lung scan at one year.
