Although acquired left ventricular outflow obstruction has been reported in a variety of conditions, there are scant reports of its occurrence following mitral valve replacement (MVR). This study describes two female patients, who developed severe discrete subaortic stenosis, five years following MVR. In both cases, the mitral valve was replaced by a porcine Carpentier-Edwards 27-mm bioprosthesis with preservation of mitral valve leaflets. The risk of very late left ventricular outflow tract obstruction after bio-prosthetic MVR with preservation of subvalvular apparatus needs to be kept in mind in symptomatic patients...

Aortic valve bioprostheses are commonly implanted in the current era (also in younger patients) as they may obviate the need for anticoagulation while providing better hemodynamic performance and a more favorable quality of life. The steady increase in the use of biological valves has prompted the development of several different models of conventional stented bioprostheses. At present, there are four main types of stented aortic bioprostheses that compete in the market: the LivaNova Crown PRT (LivaNova Group, Burnaby, Canada), the St...

We report on a transapical tricuspid valve-in-ring implantation performed via right ventricular apex using the Sapien-XT-prosthesis. A 57-year-old woman with recurrent episodes of right heart failure and three previous sternotomies, including tricuspid valve repair with a 32 mm Carpentier-Edwards-Classic annuloplasty ring was admitted due to recurrent severe tricuspid regurgitation. Given the excessive surgical risk, a 29 mm Sapien-XT-prosthesis was selected for valve-in-ring implantation. Transapical valve-in-ring implantation procedure was uneventful...

A 72-year old man with an unruptured aneurysm of the right sinus of Valsalva and aortic insufficiency underwent aortic root replacement using a valved composite graft created with a 28-mm woven Dacron graft (Gelweave Valsalva™ graft, Vascutek Terumo, Renfrewshire, Scotland) and a 25-mm stented bioprosthetic aortic valve (Carpentier-Edwards PERIMOUNT pericardial bioprosthesis, Edwards Lifesciences, Irvine, CA, USA). His postoperative course was uneventful. He had undergone a follow-up CT scan once a year. Although no abnormal signs were detected 5 years after surgery, a CT scan performed in the sixth postoperative year revealed an aortic false aneurysm around the Dacron graft...

We report the case of a 64-year old man presenting with pulmonary oedema due to the degeneration of mitral and aortic bioprostheses. Baseline transthoracic and 3D transoesophageal echocardiography showed severe stenotic degeneration of the mitral bioprosthesis (Carpentier-Edwards bioprosthesis n°31), severe intraprosthetic aortic regurgitation (Perimount bioprosthesis n°27), left ventricular dilatation, decreased left ventricular ejection fraction at 50% and pulmonary hypertension. Because of severe comorbidities, the patient was denied redo surgery by the Heart Team (logistic EuroSCORE 2: 23, 85%)...

A 77-year-old woman who had undergone mitral valve replacement (MVR) with a 29 mm Hancock standard (H-S) bioprosthesis (Model 242) and tricuspid annuloplasty (Kay's method) at the age of 44 years was admitted urgently with acute heart failure. Echocardiography showed severe transvalvular leakage of the prosthesis and moderate tricuspid regurgitation. The patient underwent reMVR with a 29 mm Carpentier-Edwards Perimount Magna Mitral bioprosthesis and tricuspid annuloplasty with a 30 mm MC3 ring. The explanted bioprosthesis showed mild calcification and a tear in the leaflet, dehisced commissures and pannus overgrowth...

BACKGROUND: The optimal choice for pulmonary valve replacement (PVR) remains controversial. This study hypothesized that xenografts used for PVR would result in prolonged long-term survival and freedom from reoperation. METHODS: Children and adults with congenital heart disease requiring PVR using a xenograft from 1980 to 1985 were reviewed. In all cases, the xenograft valve was either sewn or manufactured into a Dacron conduit, and the conduit was sewn to the pulmonary artery bifurcation...

Mitral stenosis (MS) after mitral valve (MV) repair is a slowly progressive condition, usually detected many years after the index MV surgery. It is defined as a mean transmitral pressure gradient (TMPG) >5 mmHg or a mitral valve area (MVA) <1.5 cm(2). Pannus formation around the mitral annulus or extending to the mitral leaflets is suggested as the main mechanism for developing delayed MS after MV repair. On the other hand, early stenosis is thought to be a direct result of an undersized annuloplasty ring...

Transcatheter aortic valve implantation (TAVI) has been established as a therapeutic option in patients with a high procedural risk presenting with severe aortic stenosis. Recent improvements of TAVI technology made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept. The self-expanding CoreValve (Medtronic, Minneapolis, MN) prosthesis has recently been redesigned and was introduced into clinical practice. We report a case of a not fully expanded Medtronic CoreValve Evolut R after deploying a 26 mm prosthesis into a degenerated 25 mm Carpentier-Edwards Perimount prosthesis...

Bioprosthetic valves degenerate over time. Transcatheter valve-in-valve procedures have become an attractive alternative to surgery. However, every valve increasingly diminishes the diameter of the valvar orifice. We report a 12-year-old female who had a previous transcatheter tricuspid valve-in-valve procedure; cracking the ring of a Carpentier Edwards Perimount valve by means of an ultrahigh pressure balloon allowed implantation of a further larger percutaneous valve. The advantage of this novel approach permits enlarging the inner valve diameter and may facilitate future interventions and prolong time to surgery...

OBJECTIVES: This study compares the durability and risk of reoperation in patients undergoing aortic valve replacement (AVR) with either a Mitroflow or a Carpentier-Edwards (CE) pericardial bioprosthesis. Since AVR with bioprosthetic valves has increased progressively in recent years as compared to mechanical valves, especially in patients aged 60-70 years, there has been renewed interest in the long-term durability of current pericardial bioprostheses. METHODS: We compared 440 AVR with Mitroflow valves with 1953 AVR with CE pericardial valves implanted from 1999 to 2014 with regard to reoperation, reoperation for structural valve deterioration (SVD) and all-cause mortality...

Transcatheter valve-in-valve mitral valve replacement provides treatment options to high-risk patients but is subject to its own complications. We present the migration of a transcatheter balloon-expandable Edwards-SAPIEN XT valve (Edwards Lifesciences, Irvine, CA) within a previously implanted surgical Carpentier-Edwards valve (Edwards Lifesciences) and our novel approach to its treatment.

BACKGROUND: To compare hemodynamic performance and clinical outcomes after aortic valve replacement for aortic stenosis with the 19-mm Carpentier-Edwards pericardial bioprosthesis versus larger valves. METHODS: Between January 1998 and December 2013, 447 consecutive patients underwent aortic valve replacement for aortic stenosis with the Carpentier-Edwards Perimount (n = 61) or Magna bioprostheses (n = 386). Based on the implanted valve size, the patients were classified into three groups: a 19-mm group (n = 54), a 21-mm group (n = 154), and a 23-mm to 27-mm group (n = 239)...

BACKGROUND: The Carpentier-Edwards Perimount Magna mitral valve bioprosthesis (Edwards Lifesciences, Irvine, CA) is a low-profile version of the earlier Perimount valve that uses the ThermaFix process for enhanced calcium removal. The Magna valve has been in use since 2008, yet no publication, until now, has verified its intermediate-term safety and efficacy. METHODS: From 2008 through 2011 (our 4-year study period), 70 Magna valves were implanted in the mitral position at a single institution (the Cleveland Clinic)...
