Effect of Stent Size on Dyssynchrony

NCT04228874 | Completed

• 1 other identifier: dyssynchrony
• Study Type: observational
• Target: 265
• Locations: 1 country
• Sites: 1

Brief Summary

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

Conditions

Left Ventricular Function

Keywords

Stent length; Stent diameter

Outcome Measures

Primary Outcomes (1)

• left ventricular systolic function

  3 months

Interventions

coronary artery stents DEVICE

Coronary angiography was done for all the patients according to the Judkins technique. All images were evaluated by an experienced operator, significant coronary artery disease was defined as \> 70 % luminar diameter stenos. The following data was obtained: * Site of stent implantation within LAD. The first Diagonal branch serves as the boundary between the proximal and mid portion of the LAD. Thus, the portion of the artery prior to the origin of the 1st diagonal is known as the proximal LAD, while the segment just below the1st diagonal branch is the mid LAD. The distal segment of the LAD is the terminal third of the artery (Cao et al., 2017). * Length, diameter and number of stents. * TIMI flow after stent deployment.

Eligibility Criteria

Study Population

adult patients with electively stented LAD lesion with DES were enrolled in the study

You may qualify if:

• 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.

You may not qualify if:

• 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.
