ABSTRACT
ntroduction: Intravascular ultrasound is a new imaging modality that facilitate the process of coronary intervention. The angiographic evaluation of left main lesions significance is always questionable, IVUSdetect the significance, guide the procedure and some studies proves a benefit in mortality.Objectives:To investigate whether intravascular ultrasound IVUS guided Left Main coronary intervention could improve clinical outcomes compared with angiographic-guided Left main coronary PCI.Patientsand Methods:This controlled study was carried out between June 2017 and June 2019, in Tanta university Hospital and San Donato Hospital, Milan, 83 patients eligible to Left Main coronary intervention divided into two groups, IVUS-guided group (n=19) and angiographic-guided group(n=64). The occurrence of major adverse cardiac events(MACE): death, non-fatal myocardial infarction, or target lesion revascularizations) were recorded 6 and18Months of follow-up Results:The IVUS-guided group had a lower rate of 18-months MACE than the control group. The incidence of target lesion revascularization was lower in the IVUS-guided group than in the control group. The incidence of TLR after 6 months was not different between both groups (1 cases in IVUS group (5.3%), 6 cases in angiography group (9.4%) (P value 0.686) while the incidence of TLR after 18 months was significantly different between both groups (1 cases in IVUS group (5.3%), 17 cases in angiography group(26.6%) (Pvalue 0.048), However, there were no differences in death, myocardial infarction, stent thrombosis and number of patients treated with CABG in the 2 groups.Conclusion:The present study demonstrates that IVUS-guided LM angioplasty can improve 18 -months MACE events especially the incidence of target lesion revascularization
ABSTRACT
Aim:This study aimed to compare between the effect ofpharmacoinvasive strategy (PI)& primary percutaneous coronary intervention (P-PCI) according to PCIrelated delay (door to ballon) on the mortality and morbidityduring in-hospital stay and after 30-day follow up. Moreover, leftventricular systolic function was assessed by two-dimensional echocardiography at cardiology department, Tanta University. Patients and Methods:The study was conducted on 300 patients that were dividedinto 2 main groups. Group A consisted of patients had primaryPCI as reperfusion therapy and further divided into threegroups according to PCI related delay (door toballon). Group A1, PCI-related delay is ≤60 minute(92patients). Group A2, PCI-related delay is >60 to ≤ 90 minute. (54patients). Group A3, PCI-related delay is >90minute (78 patients). The second group (group B), include patients who undergopharmaco-invasive strategy, PCI within 24 hour afterthrombolysis (76 patients). the second group, coronary angiography was done immediately in cases of failedthrombolysis and for successful thrombolysis; coronaryangiography was performed within 3 –24 hours. Results:During hospital stay, more patients in group A3 died than those of group B orgroup A1, A2 with no statistical significance.In addition, morepatients in group A3 showed heart failure symptoms withstatistical significance than those of group B, A1 and A2. Bleeding complications occurred significantly moreingroupB. Duringfollowupvisits more patients in group A3 complained ofheart failure symptoms with statistical significance than those of group B, A1, A2 patients. Conclusion:Primary PCIwithout door to balloon time delay (≤90 minutes)was encouraged and hadthebest results on morbidity and mortality. Also, pharmacoinvasive strategy was encouraged as being better than primary PCIwhen door to balloon time showed marked delay( <90 minutes)
