Background: Sinus of Valsalva aneurysms (SOVA) are very uncommon, with an incidence ranging from 0.1 to 3.5% of all congenital heart defects. Such aneurysms account for only 0.14% of all open heart surgical procedures. SOVA are usually diagnosed as an incidental finding or after an acute rupture into an adjacent cardiac structure. Case Report: We report a case of SOVA associated with severe aortic valve regurgitation. Conclusion: Before rupture, SOVA may present with conduction-system abnormalities attributable to erosion into the inter-ventricular septum, thromboembolism originating in the aneurysm sac, and myocardial ischemia attributable to coronary compression.

Sinus of Valsalva aneurysm (SOVA) is a rare clinical entity. Clinical manifestations can vary from an incidental finding on an imaging study to a life-threatening emergency. We report a case of SOVA associated with severe aortic valve regurgitation. Surgical repair of the aneurysm with reimplantation of the right and left coronary arteries was performed in addition to aortic valve replacement (Bentall procedure). The patient had an uneventful post-operative course and remains asymptomatic at the three-month follow-up visit.

Case Report

A 35-year-old female with no past significant medical history was admitted for exertional dyspnea during last two weeks. There was no relevant family history. Her cardiovascular physical examination was significant for IV/VI early diastolic murmur at third left inter-costal space and other peripheral signs: Corrigan pulse, Hill’s sign, Duroziez’s murmur. Her admission ECG [Fig.1] showed sinus rhythm with a heart rate of 91 bpm, left ventricular hypertrophy. Her portable chest X-ray [Fig.2] was significant for cardiomegaly. Her transthoracic echocardiogram revealed a massively enlarged aortic root with large sinuses of Valsalva aneurysms measuring ˜7.5 cm in diameter [Fig.3]. Severe aortic regurgitation was present, and left ventricular function was normal. The patient was further evaluated by computerized tomography of the ascending aorta [Fig.4a-d]. This imaging modality further confirmed the findings in the echocardiogram. These findings were not previously known by the patient. The patient denied any signs or symptoms of cardiac ischemia or embolic complications such as stroke. Subsequently, the patient underwent replacement of the aortic valve with mechanical prosthesis and Dacron conduit, with reimplantation of the right and left coronary arteries on the anterior and lateral surfaces, respectively (Bentall procedure). The post-operative course was uneventful. She remains asymptomatic at the three-month follow-up visit. Repeat echocardiography shows no residual abnormalities.


SOVA is a rare but serious cardiac anomaly. It was first described by Hope in 1839 [1]. Incidence varies from 0.1-3.5% among all congenital cardiac lesions [2]. The left SOVA is the rarest of all SOVAs (< 5%) [3,4]. SOVA can be congenital or acquired. The right coronary sinus is by far the most common site of origin for congenital SOVAs. These are usually associated with other congenital cardiac defects. Ventricular septal defects and aortic regurgitation are the most common co-existing cardiac defects. Acquired aneurysms are mostly caused by trauma, atherosclerosis, endocarditis, syphilis, and connective tissue diseases [2]. 
Most SOVAs result from a congenital deficiency of elastic lamellae in the wall of the affected sinus, with separation of the media in the sinus of Valsalva from the media adjacent to the aortic valve annulus [5]. Eventually, this weak area enlarges and becomes aneurysmal due to the effect of high aortic pressure. Clinical manifestations may vary from an incidental finding on an imaging study to a life-threatening emergency. 
Unruptured SOVAs typically remain asymptomatic for decades and are often discovered incidentally on echocardiography or other imaging modalities. However, large unruptured aneurysms can produce mass effect and may cause valvular dysfunction, right ventricular outflow tract obstruction, and myocardial ischemia due to compression on the origin of the main coronary arteries [6]. Nonetheless, acute symptoms usually occur in most cases of aneurysmal rupture and subsequent fistula formation to the adjacent cardiac chamber. Acute symptoms consist of sudden shortness of breath and chest pain. Moreover, a characteristic loud continuous murmur accompanied with a thrill is often related to rupture of the aneurysm [7].
Congenital SOVAs usually rupture during the third and fourth decade of life. Generally, aneurysms rupture into the right ventricle followed by right atrium. In contrast, left aneurysms rupture into the pericardial cavity. Other potential complications of SOVAs include aortic regurgitation, myocardial ischemia, conduction abnormalities, and thrombus formation with subsequent systemic embolization [8]. Nonetheless, heart failure is still the main cause of death in patients with SOVAs. Echocardiography is very useful in the diagnosis of SOVAs and associated lesions such as aortic regurgitation, ventricular septal defects, and endocarditis [9]. Other diagnostic modalities such as CTA, cardiac MRI, and cardiac catheterization with aortography are often necessary to confirm diagnosis, identify coronary anatomy, and detect complications. Surgical repair is the treatment of choice for ruptured SOVAs with excellent long term survival of 97% at 10 years [10,11]. An unruptured but symptomatic SOVA should also be considered for surgical intervention. Moreover, concomitant ventricular septal defects, endocarditis, and moderate to severe aortic valve regurgitation require surgery [12]. Conversely, several reports have shown that percutaneous closure of ruptured SOVA using transcatheter closure devices is feasible and effective therapeutic alternative to surgery [13-15].


Aneurysms of sinus of Valsalva are rare congenital or acquired cardiac defects that have been increasingly diagnosed as a result of improved imaging techniques. This is a case of aneurysms of all three coronary sinuses presenting with no clinical signs or symptoms. Despite being asymptomatic and having a favorable course thus far, we recommended that our patient have surgery performed as soon as possible to minimize the risk of future cardiovascular events.
