Summary

To study whether renal sympathetic denervation(RSD) will reduce the all-cause mortality and the recurrence rate of a composite of cardiovascular event(including angina, myocardial infarction, repeat percutaneous coronary intervention and coronary artery bypass grafting) in patients after percutaneous coronary intervention(PCI). Besides whether RSD can reduce the risk factors for coronary heart disease.

PROCEDURE

RSD

Contrast renal angiography was performed to localize and assess the renal arteries for accessibility and appropriateness for RSD. Once the anatomy was deemed acceptable, the internally irrigated radiofrequency ablation catheter(Celcius Thermocool,Biosense Webster, Diamond Bar, California) was introduced into each renal artery. then was maneuvered within the renal artery to allow energy delivery in a circumferential, longitudinally staggered manner to minimize the chance of renal artery stenosis. About six to nine ablations at 10 W for 1 min each were performed in both renal arteries. During ablation, the catheter system monitored tip temperature and impedance, altering radiofrequency energy delivery in response to a predetermined algorithm.

PROCEDURE

PCI

Percutaneous coronary intervention (PCI) is a non-surgical procedure used to treat the stenotic coronary arteries of the heart found in CHD. During PCI, a cardiologist feeds a deflated balloon or other device on a catheter from the inguinal femoral artery or radial artery up through blood vessels until they reach the site of blockage in the heart. X-ray imaging is used to guide the catheter threading. At the blockage, the balloon is inflated to open the artery, allowing blood to flow. A stent is often placed at the site of blockage to permanently open the artery.
