Delayed Rupture of the Right Sinus of Valsalva into the Right Atrium after Percutaneous Coronary Intervention

ABSTRACT

Rupture of the sinus of Valsalva is an extremely rare complication after percutaneous coronary intervention (PCI). Because it usually results from the retrograde extension of a dissection of the right coronary artery and may quickly spread to involve the entire aorta, it can cause life-threatening complications such as aortic dissection. If the dissection remains localized, it can resolve spontaneously in the first month. Our patient experienced a delayed rupture of the right sinus of Valsalva into the right atrium at approximately 3 months after PCI.
