Cardiac tissue approximation via mechanical suture placement

Cardiac tissue approximation via mechanical suture placement is a surgical technique or device-based procedure used in cardiovascular surgery to bring together the edges or layers of cardiac tissue, such as in the closure of defects (e.g., atrial septal defect, valve annulus, surgical incisions). This technique employs sutures (of various types and materials), barbed suture devices, or innovative mechanical approximation tools to join tissues, achieve hemostasis, and promote secure healing. These devices may be placed manually or with robotic assistance. The main goals are watertight closure, preventing tissue separation, and minimizing surgical risk. This is not a molecule or receptor but a physical intervention central to many cardiac surgeries.
