TRICUSPID VALVE ANTERIOR CUSP PROLAPSE REPAIR TECHNIQUE Russian patent published in 2024 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to cardiovascular surgery. First, suture repair of a stretched fibrous ring of the tricuspid valve is performed, narrowing its opening to normal sizes. Thereafter, the value of the prolapse portion of the anterior cusp above the level of the annulus fibrosus is determined by means of a hydraulic test. Then, the prolapse portion of the cusp is corrected by applying shortening sutures of U-sutures on the central portion of the zone of comparing the prolapse cusp of the tricuspid valve. At that, the prick-in is started on the atrial side of the cusp matching zone, then the suture is delivered under the matching zone, and the filament is pricked out into the smooth body of the anterior cusp, 2–3 mm from the line of transition of the zone of matching the cusp into its smooth zone, avoiding tendon chords of the anterior cusp.

EFFECT: method enables reducing the risk of intraoperative complications and is "recurrent", which enables to continue the correction by other methods.
