Effect of Stent Size on Dyssynchrony

The Short Term Effect of Stent Size and Number on Left Ventricular Mechanical Dyssynchrony After Elective PCI to Left Anterior Descending Artery

the effect of stent size and number on left ventricular mechanical dyssynchrony after PCI using drug eluting stent is not clear enough

Background: the effect of stent size and number on left ventricular mechanical dyssynchrony after PCI using drug eluting stent is not clear enough Aim: to study short term effect of stent size and number on left ventricular mechanical dyssynchrony after elective PCI to LAD artery.

Patients and methods: the study included 150 adult patients with electively stented LAD lesion with DES. Patients were evaluated pre PCI then follow up at 1m and 3m using tissue synchronization image (TSI).

Inclusion Criteria:

• adult patients with electively stented LAD lesion with DES were enrolled in the study. Patients were evaluated pre PCI then follow up at 1m and 3m after PCI using TSI.

Exclusion Criteria:

• patients with Bundle branch block (BBB),
• Previous percutaneous coronary intervention (PCI),
• Previous coronary artery bypass graft (CABG),
• Rhythm other than sinus,
• Rheumatic heart disease,
• Prosthetic valve,
• Complicated or unsuccessful procedure,
• Patients with significant degenerative changes,
• Patients with previous STEMI,
• and dropped patients from follow up were excluded from the study.
