Myocardial infarction is the leading cause of death in most of the industrializedcountries.Manual aspiration catheters are new devices that are used during primary PCIaiming to improve myocardial perfusion by reducing the thrombus burden in theinfarct related artery.This study aimed to define the benefits of thrombus aspiration by EXPORTsuction catheter during primary PCI for acute STEMI in terms of angiographicresults (TIMI flow, MBG) and ST resolution after PCI, morbidity and mortalitywithin 30 days after PCI.This study was carried on 30 patients who presented with acute STEMI within12 hours of chest pain to the emergency department of “Prince Sultan CardiacCenter, Al-Hassa, KSA” during the period from April 2010 to October 2010.Patients were divided into two groups; fifteen patients were subjected tothrombectomy device (EXPORT suction catheter) before proceeding to theprimary PCI and this group was considered as group (1), and the remaining 15patients were subjected to conventional primary PCI and this group was consideredas group (2).The use of EXPORT suction catheter during primary PCI for acute STEMI isfeasible in the majority of the cases and it results in significant improvement inmyocardial perfusion as evidenced by better myocardial blush grade (MBG) aswell as better TIMI flow after PCI.162There was better ST resolution 90 minutes after PCI, less incidence of persistentST deviation with the use of Export suction catheter.The use of Export suction catheter reduced the need for balloon predilatationbefore stenting.The use of Export suction catheter resulted in improvement of the leftventricular ejection fraction.But, it did not show difference in morbidity or mortality within 30 days afterPCI.
