Direct coronary stenting in reducing radiation and radiocontrast consumption

Direct coronary stenting in reducing radiation and radiocontrast consumption

INTRODUCTION Coronary stenting is the primary means of coronary revascularization. There are two basic techniques of stent implantation: stenting with balloon predilatation of stenosis and stenting without predilatation (direct stenting). Limiting the time that a fluoroscope is activated and by appropriately managing the intensity of the applied radiation, the operator limits radiation in the e...

Direct coronary stenting without predilation.

OBJECTIVES Coronary stenting is the primary therapeutic option for percutaneous treatment of many coronary lesions, after the risk of subacute stent thrombosis and bleeding complications has been reduced by improved antithrombotic regimens and high pressure stent expansion. BACKGROUND Direct stent implantation (without predilation) has been considered a promising new technique that may reduce...

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Minimally invasive direct coronary artery bypass versus stenting.

We readwith great interest the article by Boodhwani et al. [1] titled ‘Mortality and myocardial infarction following surgical versus percutaneous revascularization of isolated left anterior descending artery disease: a meta-analysis’. Randomized studies demonstrated a beneficial effect of surgery compared to percutaneous therapy on mid-term (1 month to 5 years) major adverse cardiac events (MAC...
