Follow up of the patients treated with the mguard stent system in percutaneous coronary intervention [pci] at afic-nihd

ABSTRACT

The objective of this study was to conduct a clinical and angiographic follow up of the patients treated with the MGuard Stent used in PCI in the setting of acute coronary syndromes. The study was conducted in AFIC-NIHD Rawalpindi, from April 2010 and October 2010 twenty one patients were treated with a total of 25 MGuard stents. Patients included were those having de novo lesions in saphenous vein grafts or native vessels with angiographic evidence of thrombus and lesion instability with a potential for distal embolization in the setting of acute coronary syndromes. All patients were male. Mean age was 46.23 years [range 32-70 years]. Fourteen patients were admitted with ST elevation MI, 4 with Non-ST elevation MI, and 3 with unstable angina. Two vein grafts were stented while the rest were de novo lesions in native coronary arteries. The mean vessel diameter was 3.0mm [2.5- 3.5]. The stent length ranged from 12 to 39 mm. MGuard stent was deployed successfully with no complications of PCI [distal embolization]. Secondary endpoints [TIMI- III flow and myocardial blush grade 3] were met in all cases. One patient died within 30 days of PCI. On follow up 9 patients [42%] had critical ISR [2 of these were total occlusions] and all required repeat intervention. Total MACE events were 47% [1 death and 9 TLR]. Angiographic follow up of MGuard stent at 6 month showed significant ISR which needs to be clarified with a larger sample size
