OBJECTIVES: Bioprosthetic aortic heart valves are increasingly implanted in younger patients. Therefore, a strategy for potential valve failure should be developed before implanting the 'first valve'. The goal of this in vitro study was to provide insight into the effects of the design of a bioprosthesis on a valve-in-valve implanted Sapien XT valve. METHODS: The hydrodynamic performance of a 23-mm Sapien XT valve implanted in Vascutek Aspire, Edwards Perimount, Medtronic Mosaic and St...

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...

BACKGROUND: Outcomes after surgical pulmonary valve replacement (PVR) in patients with congenital cardiac disease are limited by long-term valve deterioration, which may be hastened by turbulent flow. The use of the Trifecta valve (St. Jude Medical, Little Canada, MN) at our institution (Duke University Medical Center, Durham, NC) appears to result in low postimplantation transvalvular gradients. This study was performed to compare the early transvalvular gradient associated with the Trifecta valve with that associated with two other valves commonly used for PVR...

Objective Endovascular valve in stented biological valve implantation (valve-in-valve transcatheter aortic valve implantation [TAVI ViV]) is increasingly becoming a valid option for bioprosthesis degeneration. TAVI implantation in small stented biological valves below 23 mm is controversially discussed. Reduced opening area and high gradients are typical objections against this procedure in cases of small bioprosthesis. Systematic studies about the hemodynamic performance of endovascular valves in small stented bioprosthesis, however, do not exist...

OBJECTIVES: The purpose of this study was to optimize hemodynamic performance of valve-in-valve (VIV) according to transcatheter heart valve (THV) type (balloon vs. self-expandable), size, and deployment positions in an in vitro model. BACKGROUND: VIV transcatheter aortic valve replacement is increasingly used for the treatment of patients with a failing surgical bioprosthesis. However, there is a paucity in understanding the THV hemodynamic performance in this setting...

Experience with pericardial bioprostheses in young patients is limited. Accelerated degeneration of the Mitroflow valve has recently been reported. We report early accelerated structural valve degeneration with the Perimount Magna bioprosthesis, which has not been previously reported. Young patients with the Magna bioprosthesis are at high risk for rapid progression to severe stenosis, which underscores their need for more vigilant surveillance. The benefits and risks of these bioprosthetic valves must be weighed carefully when options for replacement in these young patients are discussed...

A 90-year-old man presented with increasing exertional breathlessness. He had previous implantation of a Perimount bioprosthetic aortic valve (Edwards Lifesciences) and coronary artery bypass graft surgery. Due to severe transvalvular bioprosthetic regurgitation with preserved left ventricular dimensions and ejection fraction, the heart team decided on valve-in- valve transcatheter aortic valve implantation via the transfemoral route in view of the patient's prohibitively high surgical and anesthetic risk. The patient had an uncomplicated recovery and was symptomatically much improved at 3-month follow-up...

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...

Bioprosthesis degeneration is a relevant clinical issue that is increasingly developing with the higher expectancy of life. Its treatment may be further complicated by the presence of paravalvular leaks, which are usually consequence of tissue friability, annular calcification, and infection. The surgical treatment of such complex conditions may be too risky, so percutaneous techniques in selected centers are becoming an attracting option. We report the case of a 65-year-old gentleman with a previous aortic valve replacement (Perimount n...

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...
