Abstract:

Objective

To assess the pathologic anatomy features of right coronary artery fistula to left ventricle and the diagnostic value of echocardiography.

Methods

One adult with right coronary artery fistula to left ventricle who admitted to Qingdao Municipal Hospital (Group) on May 14, 2015 and 31 cases who reported by literatures were enrolled in this study.The echocardiographic characteristics and echocardiographic diagnostic value of right coronary artery left ventricular fistula were analyzed.

Results

All 32 cases were confirmed by surgery or angiography, including 29 cases of surgical cases.Twenty-nine cases were diagnosed by preoperative echocardiography, the diagnosis coincidence rate was 90.63%; Two case were diagnosed by preoperative ultrasonography (not clear) combined with imaging diagnosis.One case was misdiagnosed as sinus of valsalva aneurism rupture, the misdiagnosis rate was 3.12%.

Conclusion

Echocardiography can real-time dynamically display pathological anatomy of right coronary artery to left ventricular fistula and hemodynamic changes dynamically noninvasively, quickly, efficiently with high, accurately.It is the preferred method in the diagnosis of right coronary artery left ventricular fistula.

Key words: Echocardiography, Coronary vessels, Fistula
