We present the case of a 10-month-old female with a right coronary sinus of Valsalva aneurysm with rupture into the right atrial appendage who presented with a murmur. Surgical repair was performed shortly after diagnosis with pericardial patch closure from within the aorta and closure of the right atrial rupture site. To our knowledge, this is the youngest child with sinus of Valsalva aneurysm with rupture to be identified in the literature.

Echocardiography is the primary modality for imaging the aorta for the diagnosis and serial evaluation of pathological conditions. In this article, we review the methodology for optimal echocardiographic imaging of the various segments of the aorta and discuss abnormalities of the aorta including stenosis, dilation including aortopathy and sinus of Valsalva aneurysms, and fistulous communications involving the ascending aorta including aortoventricular tunnel and ruptured sinus of Valsalva aneurysm. We review novel echocardiographic measurements of aortic functional properties of the aorta such as elasticity and stiffness, and review the literature on the potential additive value of such measurements for structural assessment alone. Finally, we discuss the limitations of echocardiography in the precise and optimal imaging of the aorta.

Aneurysm of the sinus of Valsalva is a rare congenital cardiac anomaly. It occurs as an outpouching that progresses like a windsock, and it may rupture producing aortic regurgitation, cardiac tamponade, congestive heart failure, conduction abnormalities, and stroke. We describe a case of rupture of the sinus of Valsalva into the interventricular septum producing a large dissecting aneurysm. Despite the location, it did not produce a conduction abnormality.

There is a collection of rare congenital cardiac defects that can produce significant haemodynamic embarrassment. Owing to their rarity, these lesions may be overlooked or mistaken for other more common congenital cardiac defects. Using careful segmental echocardiographic techniques, such as multiple planes of imaging and inferential Doppler findings, it is possible to identify these lesions and thus plan surgical management. Some of the lesions of importance reviewed include the aortopulmonary window, the aorto-ventricular tunnels, the aorto-atrial tunnels, and aneurysm of the sinuses of Valsalva. Some conditions such as the aortopulmonary window and aneurysm of the sinuses of Valsalva often occur in the setting of other congenital cardiac lesions. At times, the presence of coexisting lesions may mask some of the characteristic features of these defects. With prompt identification, all of these rare conditions are amenable to complete surgical repair. Newer modalities such as three-dimensional echocardiography can further enhance surgical planning.

This study reviews the results of the surgical management of 154 cases of ruptured aneurysm of the sinus of Valsalva. Of the patients0 73% were male, with an average age of 28 years. An associated ventricular septal defect was found in 40% and 23% had aortic valvar regurgitation. The aneurysms originated from the right coronary sinus in 79% and from the non-coronary sinus in the remainders. The aneurysms ruptured into the right ventricle in 73%, into the right atrium in 27% and into the left ventricle in less than 1%. Operative mortality was 4.5%. Long-term follow-up was achieved in 80% of patients, with a mean duration of 5.7 years and a range from two months to 29 years. Preoperative aortic regurgitation and preoperative functional class (NYHA III or IV) were both predictive of a worse long-term outcome. The optimal surgical approach was closure of the distal end of the fistula by direct suture together with reinforcement of the aortic sinus with a Dacron patch.

Ruptured aneurysm of an aortic sinus of Valsalva is a rare cause of left-to-right shunting. We show how resonance imaging can be used to make the diagnosis. This technique can successfully characterize the shunt as well as determine the presence of associated anomalies, such as ventricular septation and aortic regurgitation. It may be the only study required prior to therapeutic intervention.
