Abstract Background: Bifurcation lesions are frequent among patients with symptomatic coronary artery disease treated by percutaneous coronary intervention. Current evidence recommends a conservative (provisional) approach when treating the side branch (SB). Here, the aim was to determine the effect of different bifurcation techniques (one stent and two stent strategies) on LV myocardial function assessed by speckle tracking echocardiography in patients subjected to elective PCI. |
