AORTIC ROOT REPLACEMENT (BENTALL'S PROCEDURE) FOR IMPENDING RUPTURE OF SINUS OF VALSALVA

Clinical Presentation

A 64-year-old patient was referred for an aortic valve replacement. On history, the patient had a prior episode of fever, which had been treated briefly with a short course of antibiotics. Preoperative evaluation confirmed the need for aortic valve surgery, and the patient was taken up for planned valve replacement.

Intraoperative Findings

During surgery, an intraoperative Transesophageal Echocardiogram (TEE) revealed an unexpected and critical finding: an impending rupture of the Sinus of Valsalva. This was subsequently confirmed on direct surgical inspection. Given the patient's history of a recent febrile illness, the finding raised the possibility of an underlying infective process weakening the aortic root, which had gone undetected prior to surgery.

About the Condition

The sinus of Valsalva is one of three dilated pockets located at the root of the aorta, just above the aortic valve. Weakening of this structure, whether congenital, degenerative, or infective in origin, can lead to aneurysmal dilation and, if untreated, rupture. An impending rupture identified intraoperatively requires immediate change in surgical strategy to prevent a life-threatening outcome on the operating table.

Procedure

Given the intraoperative finding, the surgical plan was extended beyond isolated valve replacement. The patient underwent an aortic root replacement using the Bentall's procedure, a composite graft technique in which the aortic root, aortic valve, and ascending aorta are replaced together with a valved conduit, and the coronary arteries are re-implanted into the new graft. This addressed both the valve pathology and the compromised aortic root in a single definitive operation.

Postoperative Outcome

The postoperative course was uncomplicated. The patient recovered well, with no major complications during the recovery period.

Conclusion

This case highlights the critical role of intraoperative imaging, particularly Transesophageal Echocardiography, in identifying life-threatening findings that may not be apparent on preoperative workup. A patient's history, including something as seemingly minor as a recent febrile illness, can be an important clue to underlying aortic root pathology. The ability to adapt the surgical plan in real time, from an isolated valve replacement to a complete Bentall's procedure, was key to a successful outcome in this case.
