Case Description: Seventy-nine-year-old woman with permanent atrial fibrillation and scoliosis was admitted to the Department of Internal Diseases because of effort intolerance and back pain. Her physical examination revealed body mass index 20 kg/m2, small body surface area 1.38 m2, and systolic murmur over the heart. Transthoracic echocardiography (TTE) indicated confusing oval structure filling the right ventricle and the lack of aortic wall in the parasternal long-axis view which raised the suspicion of some septal or artery wall defect (Figs. 1–2). Considering these doubts, the patient was transferred to Cardiology Department. Detailed 2D and 3DTTE demonstrated huge aneurysm of right Valsalva sinus causing dilatation of aorta reaching 73 mm, which modeled right ventricle (RV) and was seen as oval structure filling RV cavity. Interestingly, aortic annulus was not dilated (23 mm) with only mild aortic insufficiency. Color Doppler did not corroborate septal defect but indicated on turbulent flow inside RV (Fig. 3 and movie clip S1). Computed tomography confirmed the diagnosis of unruptured aneurysm of right aortic sinus (Fig. 4). Our case is atypical due to relatively large dimensions of aneurysm, which seemed to fill completely RV cavity and was misdiagnosed by less experienced echocardiographer.

Aneurysm of Valsalva sinus (SVA) is a rare, usually congenital anomaly, sometimes connected with supracristal VSD, although traumatic, infective, and inflammatory origins were also described.1 Unruptured SVA may be asymptomatic, cause RV outflow tract obstruction, compress coronary arteries, or lead to thrombotic complications—acute coronary syndrome or stroke.2,3 Surgical and percutaneous interventions with occluding devices are applied in patients with SVA.4

Figure 1. Presentation of SVA in 2D parasternal long-axis view (LAX) suggesting “lack of aortic wall” over interventricular septum (red arrow) which in the reality corresponds with the neck of right Valsalva sinus aneurysm. Ao = ascending aorta; LA = left atrium; LV = left ventricle; RV = right ventricle; SVA = sinus Valsalva aneurysm.

Figure 3. Presentation of SVA in color Doppler echocardiography in parasternal long-axis view. Arrows indicate SVA and its neck without flow of significant velocity as well as turbulent diastolic flow in right ventricle related to the obstruction of RV cavity with SVA and mild, central aortic regurgitation. AR = aortic regurgitation; SVA = sinus Valsalva aneurysm; RV = right ventricle.
