OBJECTIVES: Reoperative procedure for the treatment of a failed mitral bioprosthesis is associated with considerable risk. In some cases, mortality is high and might contraindicate the benefit of the procedure. The minimally invasive valve-in-valve (ViV) transcatheter mitral valve implant offers an alternative less-invasive approach, reducing morbidity and mortality. The objective of this paper was to evaluate the mitral ViV approach using the Braile Inovare prosthesis. METHODS: The transcatheter balloon-expandable Braile Inovare prosthesis was used in 12 cases...

PURPOSE OF REVIEW: Structural valve deterioration is the major cause of bioprosthesis failure and is increasing over time. We present an overview of incidence, mechanisms, predictors, clinical impact, and management of bioprosthetic valve structural degeneration. RECENT FINDINGS: Early degeneration caused by calcification and destruction of connective tissue of the prosthesis is controlled by multiple mechanisms, from mechanical stress to infiltration of lipids and inflammatory cells, and activation of the immune system...

BACKGROUND: Symptomatic mitral regurgitation (MR) is associated with high morbidity and mortality that can be ameliorated by surgical valve repair or replacement. Despite this, many patients with MR do not undergo surgery. Transcatheter mitral valve replacement (TMVR) may be an option for selected patients with severe MR. OBJECTIVES: This study aimed to examine the effectiveness and safety of TMVR in a cohort of patients with native valve MR who were at high risk for cardiac surgery...

Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk. The rapid technologic advances and the recent improvement of clinical outcomes with TAVI have made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept (Walther T, Simon P, Dewey T, et al. Transapical minimally invasive aortic valve implantation: multicenter experience...

Mitral valve surgery has changed with the wide acceptance of mitral valve repair. The aim of this study is to obtain the long-term results of patients who underwent mitral valve replacement (MVR) using a biological prosthesis in contemporary practice in Japan. From January 1990 to December 2013, 76 patients underwent MVR using a biological prosthesis with or without concomitant surgery. Data were obtained by means of a questionnaire and a telephone interview. The mean follow-up period was 4.26 years. The etiologies of the patients included dilated cardiomyopathy (DCM) (n=20 [26...

This is a report of the first Brazilian experience with the Perceval sutureless aortic prosthesis in two patients with severe aortic stenosis. Transesophageal echocardiography was used during the procedure. The aortotomy was performed 1 cm above the sinotubular junction, followed by leaflets removal and decalcification. Correct valve size was selected, device released and an accommodation balloon used. The cardiopulmonary bypass times were 47 and 38 min and the cross-clamp times were 38 and 30 min. There was a significant decrease in mean gradients (41 and 75 mmHg preoperatively; 7 and 8 mmHg postoperatively)...

OBJECTIVE: In this paper, we present an endoscopic expandable sizer conceived to allow thoracoscopic aortic valve replacement with a sutureless prosthesis using a dynamic sizing of the aortic annulus. METHODS: Ten aortic torsos were prepared using a five-trocar thoracoscopic setting. Once the aortotomy was performed and the aortic valve leaflets removed, the technical feasibility of the endoscopic sizing (introduction into the trocar, expansion into the aortic annulus, determination of the valve size, and retraction) with the device was assessed...

Aortic prosthetic valve endocarditis (PVE) is a potentially life-threatening disease. Mortality and incidence of infective endocarditis have been reduced in the past 30 years. Medical treatment of aortic PVE may be successful in patients who have a prompt response after antibiotic treatment and who do not have prosthetic dysfunction. In advanced stages, antibiotic therapy alone is insufficient to control the disease, and surgical intervention is necessary. Surgical treatment may be lifesaving, but it is still associated with considerable morbidity and mortality...

Transcatheter Aortic Valve Implantation (TAVI) is a well-described treatment for symptomatic calcific severe aortic stenosis. However, TAVI technology is being increasingly used around the world to treat selected cases of severe aortic regurgitation (AR). One of the main limitations of using TAVI technology for AR is the lack of calcification, which is common in such cases. This makes anchoring of a TAVI prosthesis to the aortic annulus difficult and risks displacement or embolization. However, with the availability of recapturable and repositionable TAVI technologies, these limitations have been overcome to a large extent...

Individualised, patient-centred care is a central tenet of modern medicine. The variety of transcatheter heart valves currently available affords the opportunity to select the most appropriate device for each individual patient. Prosthesis selection should be based on operator experience and pre-procedural multimodal three-dimensional imaging. Herein, we outline a number of clinical scenarios where specific transcatheter heart valve technologies have the potential to optimise clinical outcome.

Valve embolization during transcatheter aortic valve implantation is a rare but potentially fatal complication of first generation transcatheter valves. As a result, second generation valves were designed to be fully retrievable and minimize this complication. We report a first case of embolization with a second-generation fully-retrievable and repositionable Lotus valve. In this case, the presence of severe left ventricular hypertrophy and a sigmoid septum may have contributed to prosthesis embolization with the initial 23mm Lotus valve...

OBJECTIVES: To evaluate the safety and midterm hemodynamic results of direct transcatheter aortic valve replacement (TAVR) without pre-implantation balloon aortic valvuloplasty (BAV). BACKGROUND: BAV was considered a mandatory previous step in TAVR procedures. METHODS: A total of 339 consecutive patients who underwent transfemoral TAVR were prospectively selected. A 1:1 matching was conducted, pairing age, prosthesis type (self-expandable or balloon expandable) and size, and valve calcification grade (48% with moderate to severe valve calcification)...

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...
