Patients with surgical bioprosthesis valve dysfunction represent a clinical challenge because, although a new surgical replacement is considered the standard treatment, the reoperation is associated with high morbidity and mortality. These patients are characterized as high surgical risk or inoperable, due to multiple comorbidities, advanced age, clinical frailty, or reduced ventricular ejection fraction.
The outcomes were categorized according to the Valve Academic Research Consortium (VARC)-2 criteria, and the events were adjudicated by two experienced cardiologists. The primary outcome analyzed was device success, defined as the implantation of a single prosthesis in the planned location, with no prosthesis-patient mismatch, mean aortic transvalvular gradient mmHg or peak velocity major vascular complications, or valvular dysfunction requiring reintervention. The clinical efficacy criteria (30 days after the procedure) consisted of the combined outcome involving mortality from all causes, stroke, rehospitalization for heart failure, New York Heart Association (NYHA) functional class III or IV, or VIV prosthesis dysfunction (stenosis or regurgitation).

Clinical, echocardiographic, and procedural profiles were characterized, and the mid-term results of patients with surgical bioprosthesis dysfunction submitted to valve-in-valve implantation in the aortic position were reported.
The valve-in-valve procedure was effective in most high-risk surgical patients with bioprosthesis dysfunction. When performed in well-selected patients, it results in satisfactory clinical and hemodynamic outcomes.

This analysis included patients older than 18 years with symptomatic aortic bioprosthesis dysfunction, consecutively submitted to VIV procedure at two tertiary cardiology centers between January 2009 and June 2015. Patients with previous transcatheter aortic valve procedures or active infective endocarditis were excluded from the sample. The project was approved by the institutional Ethics Committee, and the patients signed an informed consent. Data were prospectively recorded in appropriate forms developed for the study, stored in spreadsheets, and collected from the database of each institution.
Specific characteristics of the surgical prosthesis were assessed to support the indication of VIV procedure. The type, model, size, and position (intra- or supra-annular) of the surgical valve prosthesis were identified. The internal diameter of each bioprosthesis was obtained from the manufacturer's information. Technical aspects of the employed surgery, such as the need for reconstruction of the aortic root and the presence of venous or arterial grafts, were also elucidated.

The knowledge of the fluoroscopic aspect of a particular surgical prosthesis defines the optimum position for the transcatheter bioprosthesis implantation (usually 15% below the suture annulus for the Sapien XT and from zero to 4mm for the Core Valve prosthesis) (). Currently, the smartphone application developed in 2013 by Bapat allows access to the necessary structural information of several surgical prostheses, assisting in the most appropriate choice of size and positioning of the VIV prosthesis, thus reducing the possibility of mismatch and aortic regurgitation.

Feasibility of Valve-in-Valve Procedure for Degenerated St
In general, the clinical success of percutaneous transcatheter aortic valve implantation (TAVI) is fundamentally related to the baseline characteristics of the treated patients, to the technique employed, and to the devices used. Accumulated knowledge plays an important role to improve its results. In recent years, in particular, important concepts have been applied to VIV procedures. In this series, the first treated patient developed moderate mismatch and paraprosthetic regurgitation, potentially associated with the size of the transcatheter prosthesis used and its position. This patient had an adverse outcome, with cardiogenic shock after the procedure. At that stage of the learning curve, characteristics currently recognized as fundamental for VIV procedures had not yet been assessed or described.
