Background:
Paravalvular leak (PVL) is a well-known complication of aortic valve replacement. Currently, there is no consensus on optimal intraoperative management of patients with mild-to-moderate or moderate PVL.
Technique:
In this paper we present four novel surgical techniques, each combining suturing with sealing technique, to repair aortic PVLs, nullifying the need to replace the prosthesis.
Conclusion:
These techniques will offer cardiac surgeons new alternatives to the repair techniques currently used.
