4D Auto LAQ評(píng)估陣發(fā)性房顫患者射頻消融術(shù)前左心房基質(zhì)的臨床價(jià)值

4DAutoLAQ評(píng)估陣發(fā)性房顫患者射頻消融術(shù)前左心房基質(zhì)的臨床價(jià)值摘要：陣發(fā)性房顫是心房顫動(dòng)最常見的類型，對(duì)心功能和預(yù)后等均有明顯影響，射頻消融已被廣泛應(yīng)用于其治療。本研究旨在探討通過4DAutoLAQ評(píng)估陣發(fā)性房顫患者射頻消融術(shù)前左心房基質(zhì)的臨床價(jià)值。通過對(duì)100例陣發(fā)性房顫患者的射頻消融手術(shù)前進(jìn)行左心房基質(zhì)評(píng)估，發(fā)現(xiàn)通過4DAutoLAQ評(píng)估，可以更加準(zhǔn)確地定位左心房?jī)?nèi)的異位起搏點(diǎn)，從而針對(duì)性地實(shí)施消融手術(shù)。在隨訪中發(fā)現(xiàn)，與傳統(tǒng)消融方式相比，采用4DAutoLAQ評(píng)估后的消融手術(shù)，消融效果更加顯著，且存在更少的并發(fā)癥和心律失常。因此，本研究認(rèn)為通過4DAutoLAQ評(píng)估陣發(fā)性房顫患者射頻消融術(shù)前左心房基質(zhì)具有臨床價(jià)值。
