ABSTRACT
ObjectiveTo summarize the echocardiographic features of sinus of Valsalva aneurysm (SVA), analyze the causes of missed diagnosis, thus explore the diagnostic skills and improve the diagnostic accuracy for SVA. MethodsThe echocardiographic features and clinical data of 52 SVA patients who underwent surgery in the First Affiliated Hospital of Sun Yat-sen University from January 2014 to March 2022 were retrospectively reviewed. The patients were divided into 5 types according to modified Sakakibara classification system. ResultsThere were 32 male and 20 female patients with their age of 18~66 (36.1±11.6) years. Of the 52 aneurysms, 44 originated from the right coronary sinus (RCS), 8 from noncoronary sinus (NCS) and none from left coronary sinus (LCS). Among the 35 SVAs protruding into the right ventricle, including type I, type Ⅱ and type Ⅲv, 32 (91.4%) were associated with ventricular septal defect (VSD). There were 2 (17.6%) associated with VSD among the 17 SVAs protruding into the right atrium or other sites of the heart, including type Ⅲa, type Ⅳ and type Ⅴ. SVA was frequently associated with aortic valve disease, 27 cases (51.9%) of which needed surgical valve replacement or valvoplasty. SVA was missed in 4 patients and VSD in 8, with the misdiagnosis rates of 7.7% and 23.5%, respectively. The most commonly missed VSD diagnosis was subarterial VSD with type I SVA. Of the 19 SVAs associated with infective endocarditis (IE), 2 were missed, with the misdiagnosis rate of 10.5%. ConclusionThe ultrasound images of SVA are diverse and complex. SVA protruding into the right atrium is rarely associated with VSD, while SVA protruding into the right ventricle is frequently associated with VSD. SVA is also prone to be associated with aortic valve disease and IE, which makes the diagnosis more challenging. Therefore, during ultrasound examination, we must vigilantly and flexibly make use of the multiple scan slices so as to decrease the rate of missed diagnosis and improve the diagnostic accuracy for SVA.
