Pulmoner Arteriyel Hipertansiyonun Bir Sıçan Modelinde Sağ Ventrikül Fonksiyonunun Kapsamlı Ekokardiyografik Değerlendirmesi

Overview

This study details the echocardiographic characterization of right ventricular morphology and function in a rat model of pulmonary arterial hypertension induced by Monocrotaline. The protocol highlights the importance of proficient imaging techniques for assessing the right ventricle's size and performance, revealing significant morphological changes in the right ventricle of treated rats.

Key Study Components

Research Area

• Cardiovascular imaging
• Pulmonary hypertension
• Echocardiography techniques

Background

• Pulmonary arterial hypertension affects right ventricular function.
• Echocardiographic evaluations are critical for understanding cardiac structure.
• Previous studies have utilized monocrotaline to induce pulmonary hypertension in animal models.

Methods Used

• Echocardiographic imaging techniques for right ventricular assessment
• Rat model of pulmonary hypertension
• Measurement of right atrial and right ventricular dimensions

Main Results

• MCT-treated rats displayed significant dilation of the right ventricle.
• Key echocardiographic parameters such as RV wall thickness indicated altered function.
• Reduced TAPSE values in MCT-treated rats suggest compromised cardiac function.

Conclusions
