A Modified “Sandwich” Technique for Penetrating Left Ventricular Wounds: Translating Experience from Surgical Treatment for Dissecting Aortic Aneurysms

The aim of the study To present a developed modified double patch sandwich technique, adapted from surgical treatment of dissecting aortic aneurysms, for penetrating left ventricular wounds.

Material and methods. A clinical case of a 25-year-old patient with a penetrating left ventricular wound is described. After failure of primary U-shaped sutures, a double patch sandwich technique was successfully applied. The method consists of placing teflon patches on both internal and external surfaces of the myocardium using a special suturing technique to prevent suture cutting through the tissue.

Results. After applying the sandwich technique, reliable hemostasis was achieved, which allowed the patient to be successfully weaned from cardiopulmonary bypass. The postoperative period was uneventful. Control examinations (echocardiography, MSCT) confirmed the integrity of the left ventricular wall repair. The patient was discharged on the 10th day in satisfactory condition with normal left ventricular ejection fraction (>55%).

Conclusion. The modified double-layer teflon plasty sandwich technique showed high efficiency in the treatment of penetrating left ventricular wounds. Translation of surgical experience from dissecting aortic aneurysms treatment to heart wounds demonstrates the promise of an interdisciplinary approach in cardiac surgery.
