Integration of Vent Line Monitoring in the Right Superior Pulmonary Vein for Early Detection of Paravalvular Leaks in Aortic Valve Replacement.

This article presents an innovative surgical technique for the early detection, management, and quantification of paravalvular leaks (PVLs) during aortic valve replacement. The method utilizes an endo-cavitary vent in the right superior pulmonary vein to monitor blood flow and oxygen saturation, which is crucial for the early identification and quantification of PVLs. Complementing this, transesophageal echocardiography (TEE) is used for real-time imaging and detailed assessment of the regurgitant volume, providing a comprehensive evaluation of leak severity. This integrated monitoring approach allows for precise and immediate surgical adjustments, aiming to minimize cardiopulmonary bypass (CPB) time and reduce postoperative complications. The technique not only enhances patient safety but also improves surgical outcomes by enabling better management of the surgical process. This article delineates the procedural steps and underscores the benefits of this multifaceted monitoring strategy, outlining its significant implications for advancing clinical practices in cardiac surgery.
