Abstract

The present case report describes a 72-year-old woman with drug-resistant heart failure. Cardiac resynchronization therapy was performed. Cardiac function was evaluated using a quantitative gated single-photon emission computed tomography (QGS) program with technetium-99m tetrofosmin. During atrial-right ventricular pacing, the left ventricular ejection fraction (LVEF) was 28%, end diastolic volume (EDV) was 141 mL and end systolic volume (ESV) was 101 mL. LVEF was 31%, EDV was 142 mL and ESV was 98 mL during dual chamber pacing. During atrial-left ventricular pacing, LVEF, EDV and ESV were 32%, 18 mL and 100 mL, respectively. Diastolic function was evaluated using Vcdiff software (Daiichi Radioisotope Laboratories Ltd, Japan). Cardiac resynchronization therapy may improve cardiac function, which was evaluated accurately and non-invasively by electrocardiography-gated single-photon emission computed tomography.

摘要

本病例报告描述了一名72岁的耐药性心力衰竭女性。进行了心脏再同步治疗。使用锝-99m替曲膦的定量门控单光子发射计算机断层扫描（QGS）程序评估心脏功能。在心房-右心室起搏期间，左心室射血分数（LVEF）为28%，舒张末期容积（EDV）为141 mL，收缩末期容积（ESV）为101 mL。双腔起搏期间，LVEF为31%，EDV为142 mL，ESV为98 mL。在心房-左心室起搏期间，LVEF、EDV和ESV分别为32%、18 mL和100 mL。使用Vcdiff软件（日本第一放射同位素实验室有限公司）评估舒张功能。心脏再同步治疗可能改善心脏功能，通过心电图门控单光子发射计算机断层扫描可以准确且无创地评估心脏功能。
