OBJECTIVE
To show the real value of cardiac magnetic resonance imaging (CMRI) in the evaluation of patients with symptomatic chronic aortic valve disease.
METHODS
Seventy patients--35 with aortic stenosis (AoS) and 35 with aortic regurgitation (AoR) with surgical indication, who underwent preoperative echocardiogram (ECHO) and CMRI to assess ventricular function, volumes, and left ventricular mass index using cine magnetic resonance imaging, were studied.
RESULTS
No statistically significant difference was observed between the AoS and AoR groups when ECHO and CMRI variables were compared. When compared with the type of symptom, ECHO and CMRI variables showed the same pattern.
CONCLUSION
CMRI data were in agreement with ECHO data regarding the assessment of left ventricular volume and ejection fraction, and with the clinical presentation of patients with chronic aortic valve disease.
目的
展示心脏磁共振成像（CMRI）在评估有症状的慢性主动脉瓣疾病患者中的实际价值。
方法
对70例患者进行了研究，其中35例为主动脉瓣狭窄（AoS）患者，35例为有手术指征的主动脉瓣反流（AoR）患者，这些患者均接受了术前超声心动图（ECHO）和CMRI检查，以使用电影磁共振成像评估心室功能、容积和左心室质量指数。
结果
比较AoS组和AoR组的ECHO和CMRI变量时，未观察到统计学上的显著差异。与症状类型相比，ECHO和CMRI变量呈现相同模式。
结论
在评估左心室容积和射血分数方面，CMRI数据与ECHO数据一致，且与慢性主动脉瓣疾病患者的临床表现相符。
