AORTİK DAMARDA FARKLI KALP ATIM HIZLARININ KAN AKIŞ DINAMİĞİ ÜZERİNDEKİ ETKİLERİNİN SAYISAL ANALİZİ

Abstract

Farklı kalp atım hızlarının (HR50–HR110) aortik hemodinamik parametreler üzerindeki etkileri, hesaplamalı akışkanlar dinamiği (CFD) yöntemiyle incelenmiştir. Sayısal analizlerde aort duvarı rijit kabul edilerek, tek yönlü akış çözümlemesi gerçekleştirilmiştir. Brakiyosefalik, sol ortak karotis, sol subklavyen ve abdominal aort çıkışlarında elde edilen hız profilleri ile duvar üzerindeki basınç ve duvar kayma gerilimi (WSS) dağılımları, zamana bağlı olarak karşılaştırılmıştır. Kalp atım hızının artışıyla birlikte çıkış hızlarında ve duvar üzerindeki mekanik yüklerde belirgin değişimler gözlemlenmiş; yüksek HR koşullarında daha erken ve daha yüksek tepe değerlerine ulaşılmıştır. Dalga yayılımı ve geri yansıma etkilerinin, özellikle sistol sonrası dönemde basınç ve WSS eğrileri üzerinde farklı zamanlamalarla ortaya çıktığı belirlenmiştir. Elde edilen bulgular, HR değişiminin aortik sistemdeki akış rejimi ve duvar mekaniği üzerinde doğrudan etkili olduğunu ortaya koymakta; rijit duvar modellemesinin temel dalga mekaniği analizleri açısından işlevsel bir yöntem sunduğunu göstermektedir.
