The sinus of Valsalva pseudoaneurysm is an exceedingly uncommon disorder characterized by severe pathological dilatation of the aortic root sinus, resulting in an aberrant accumulation of blood inside a false lumen subsequent to an intimal rupture. Typically, it originates from the right or non-coronary sinus, while involvement of the left sinus of Valsalva is exceedingly rare. This syndrome may be either congenital or acquired as a result of infection, trauma, or during catheter-based percutaneous procedures or surgery. If untreated, life-threatening aorto-cavitary fistulae involving neighboring heart chambers may occur. We present here a rare case of a 67-year-old patient who acquired an iatrogenic isolated left coronary sinus pseudoaneurysm following percutaneous angioplasty. Multi-modal imaging was employed to ascertain the pathology and devise the surgical plan. Intra-operative transesophageal echocardiography directed the surgical approach and validated the sufficiency of the surgical repair.
