Aneurysms of the Sinuses of Valsalva

Sinus of Valsalva aneurysms are rare cardiac anomalies which may be acquired or congenital, most commonly involving the right or noncoronary sinuses. The congenital aneurysms are more common and often caused by weakness at the junction of the aortic media and the annulus fibrosus. Acquired aneurysms are caused by conditions affecting the aortic wall, such as infections (syphilis, bacterial endocarditis, or tuberculosis), trauma, or connective tissue disorders. Unruptured aneurysms are usually found incidentally during diagnostic studies. More commonly, sinus of Valsalvaaneurysms are diagnosed after clinical sequelae of rupture. Diagnosis of sinus of Valsalva aneurysm is facilitated by echocardiography, contrast aortography, and more recently, magnetic resonance imaging. Repair is generally required for ruptured aneurysms; unruptured aneurysms encroaching on nearby structures, causing myocardial ischemia, or having the potential to rupture warrant repair. A review of the literature is presented focusing on anatomy, clinical presentation of ruptured and unruptured aneurysms, noninvasive diagnostic modalities, and techniques for repair of this anomaly.

“…Although outflow tract VT is commonly referred to as "normal heart ventricular tachycardia" because of the uniformly preserved biventricular size and function, subtle structural abnormalities such as congenital outflow tract, basal LV, or aortic sinus of valsalva aneurysms have been described and implicated in arrhythmia pathogenesis [9]- [12]. In the case previously described by Reithman et al, a LV basal aneurysm was identified in the area adjacent to the critical septal isthmus utilized by both tachycardias [6].…”

Idiopathic monomorphic ventricular tachycardia and premature ventricular complexes (PVCs) commonly arise from the right and left ventricular outflow tracts (VOT). Their mechanism is most commonly triggered activity from delayed after-depolarizations and successful ablation is performed at the site of earliest endocardial activation. Re-entrant mechanisms have been rarely described. We report a case of an otherwise healthy patient who ultimately underwent six electrophysiology studies (EPS) and suffered numerous implantable cardiac defibrillator (ICD) discharges prior to the successful radiofrequency ablation (RFA) of two idiopathic VOT tachycardias. During the sixth EPS, a proximal aortogram demonstrated a left aortic sinus of valsalva (LASV) aneurysm. Subsequntly, a novel and successful RFA strategy of aneurysm isolation was undertaken. The presence of multiple clinical or inducible VT morphologies and the characterization of a VT as re-entrant should raise concerns that a complex arrhythmogenic substrate is present and defining the anatomy with angiography or an alternative imaging modality is essential in achieving a successful ablation strategy.
