Abstract

ABSTRACT

Objective: The objective of this study was to conduct a clinical and angiographicfollow up of the patients treated with the MGuard Stent used in PCI in the setting ofacute coronary syndromes.

Methodology: The study was conducted in AFIC-NIHD Rawalpindi, from April2010 and October 2010 twenty one patients were treated with a total of 25MGuard stents. Patients included were those having de novo lesions insaphenous vein grafts or native vessels with angiographic evidence of thrombusand lesion instability with a potential for distal embolization in the setting of acutecoronary syndromes.

Results: 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 elevationMI, and 3 with unstable angina. Two vein grafts were stented while the rest werede novo lesions in native coronary arteries. The mean vessel diameter was3.0mm (2.5- 3.5). The stent length ranged from 12 to 39 mm. MGuard stent wasdeployed successfully with no complications of PCI (distal embolization).Secondary endpoints (TIMI– III flow and myocardial blush grade 3) were met inall 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 repeatintervention. Total MACE events were 47% (1 death and 9 TLR).

Conclusion: Angiographic follow up of MGuard stent at 6 month showedsignificant ISR which needs to be clarified with a larger sample size.
