BACKGROUND : Bifurcational coronary lesions are
frequent and amounts to almost one fifth of routine
practice concerning up to 15 – 20 % of cases .
Revascularization by percutaneous coronary
intervention ( PCI ), of bifurcational lesion has
become easier by stenting yet it remains a frequent
challenge.
OBJECTIVE : To evaluate the success and hospital
complications of two most frequent technique of stent
deployment in bifurcational PCI.
METHODS : We prospectively analysed the data of
140 consecutive patients with bifurcational PCI at
Ibn_Al-Bitar Hospital for cardiac surgery for the
period from July 2008 to July 2009 .
Depending on whether the side branch was stented or
not, the patient has fallen into two groups : -
Group A; stenting of the main vessel and angioplasty
of the branch.
Group B; stenting of both main vessel and its branch .
The early outcome of the bifurcational PCI and all
complications during hospitalization that include;
death, acute Myocardial infarction , emergency
percutaneous treatment and coronary artery bypass
graft (CABG) were evaluated in the studied groups.
RESULTS : The studied sample consisted of 140
patients,107(76.3%)were male and 33(23.7%) were
female. Group A consisted of 90 patients (64.3%)
while group B consisted of 50 patients(35.7%).Acute
procedural success was (94.2%) in group A and (80%)
in group B while hospital major adverse cardiac
event(MACE) were noted in 3.8% of group A and
20% of group B,(PV=0.04)
CONCLUSION: In bifurcational PCI stenting of the
side branch has made no extra advantage in term of
procedural success and early outcome.

In this article four samples of HgBa2Ca2Cu2.4Ag0.6O8+δ were prepared and irradiated with different doses of gamma radiation 6, 8 and 10 Mrad. The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. I
