“…In these patients, supra-annular replacement is useful. We have used chimney technique 1 temporarily, but there are few reports about this technique with a 2.1-year follow-up duration. 2 In our case, the peak velocity of the mitral valve inflow increased only 3 months post-operatively and required re-replacement.…”

“…The chimney technique has been reported to be used to solve patient-prosthesis mismatch in pediatrics undergoing mitral valve replacement and in adults undergoing Bentall procedure [Gonzalez 2013;Song 2020]. Interestingly, Go et al first reported the use of the chimney technique in a patient with severe mitral stenosis and massive MAC, suggesting its feasibility to avoid complete MAC debridement during mitral valve surgery [Go 2020].…”

Extensive and serious mitral annular calcification represents a troublesome obstacle in intracardiac mitral valve replacement due to time-consuming requirements and the potential of decalcification-associated complications. We report the case of a high-risk patient with extremely severe mitral insufficiency and difficult-to-debride annular calcification who received mitral replacement using a chimney technique. This approach enabled not only the minimization of mitral calcification debridement but also the reduction of surgery time. Consequently, the surgery was successful with a great postoperative outcome. Thus, this technique is a safe and feasible option to deal with intractable mitral annular calcification during mitral valve surgery.

“…In patients with a small mitral annulus, several implanting techniques have been proposed to avoid PPM, including supra-annular valve implantation [5], aortomitral patch augmentation (Manouguian method) and composite graft replacement, termed the chimney technique [6].…”

We report a case of supra-annular mitral valve replacement for a patient with prosthetic ring endocarditis that developed late after undergoing undersized mitral annuloplasty (UMAP). A 58-year-old man had undergone left ventriculoplasty and UMAP with a 26-mm semi-rigid full ring for dilated cardiomyopathy and functional mitral regurgitation. The mitral valve had progressively stenosed and he developed prosthetic ring endocarditis 5 years after the operation. In the surgery, there were brownish fresh vegetations around the anterior mitral leaflet and the prosthetic ring. The mitral annulus was very small, even after removal of the infected ring prosthesis and debridement of the infected tissues. We implanted a 22-mm mechanical prosthesis in the supra-annular position using everting mattress sutures to prevent the valve leaflets from getting stuck by the thickened subannular tissue. Herein, we discuss the surgical procedures for a shrunken mitral annulus.
