Effective prevention of massive periprocedural embolism during renal artery stenting.

We report the case of a massive embolism of atheromatous material during stenting of a tight renal artery stenosis, which was prevented by using a distal embolic protection device and aggressive aspiration of the blood through a guiding catheter. A 72-year-old man who was referred to our institution for coronary artery disease treated with coronary angioplasty underwent renal angiography which revealed a tight stenosis (99%) located at the ostium of the right renal artery extending for 15 mm into the main tract. The diameter of the artery was estimated to be 5.5 cm in the main tract, and the plaque had a soft appearance complicated by the presence of a thrombus (persistence of contrast agent in the plaque on selective renal angiography). Renal artery Doppler ultrasound and renal scintigraphy confirmed the need for renal revascularization. An embolus protection device (FilterWire EZ, Boston Scientific, Natick, MA, USA) was successfully opened distally to the stenosis after gentle predilation. After stent deployment (Genesis 5.5x18 mm, Cordis, J&J Medical, Miami Lakes, FL, USA), aggressive aspiration of the blood through the guiding catheter was performed. A large amount of embolic material with macroscopic particles was retrieved into the basket of the embolic protection device and in the blood aspirated with the guiding catheter. Good functional results were obtained on Doppler analysis of intrarenal blood flow, with a resistive index of 70. Despite the fact that the extensive use of embolic protection devices in renal artery stenting is still under discussion, this technique may be advisable in selected cases with favorable anatomy and high embolic risk, especially in patients with complex and hazy lesions.

Left main trunk ostial stenosis and aortic incompetence in Takayasu's arteritis.

A 41-year-old woman with recent onset of heart failure and angina due to aortic valve incompetence and critical left coronary ostium stenosis in the setting of Takayasu's arteritis is reported. The patient was successfully surgically treated by aortic valve replacement and coronary artery bypass with saphenous vein graft, showing a cardiac event-free 17 months follow-up. Takayasu's arteritis must be included among the possible causes of coronary artery disease and aortic valve incompetence in young female patients. Although chronic inflammation of the aortic wall may result in late graft occlusion, surgical therapy is effective for short and mid-term clinical improvement.

Clefted bicuspid aortic valve.

We report an unusual case of bicuspid aortic valve in a 67-year-old man who had aortic valve replacement for combined severe aortic stenosis with moderate aortic regurgitation. Both preoperative echocardiography and angiocardiography failed to recognize the bicuspid nature of the aortic valve, which was discovered only at surgical pathology examination. The atypical anatomic findings of the valve consisted of a "cleft-like" appearance of the ventral leaflet formed by the two conjoined cusps together with a fenestrated rudimental raphe.
