Sutureless Aortic Prosthesis Implantation: the First Brazilian Experience with Perceval Device
نویسندگان
چکیده
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). There was no major complication or paravalvular leak.

Perceval Sutureless Valve – are Sutureless Valves Here?
With the advent of transcatheter aortic valve implantation (TAVI) techniques, a renewed interest has developed in sutureless aortic valve concepts in the last decade. The main feature of sutureless aortic valve implantation is the speed of insertion, thus making implantation easier for the surgeon. As a result, cross clamp times and myocardial ischemia may be reduced. The combined procedures (C...
متن کاملAortic Root Enlargement or Sutureless Valve Implantation?
Aortic valve replacement (AVR) in patients with a small aortic annulus is a challenging issue. The importance of prosthesis-patient mismatch (PPM) post aortic valve replacement (AVR) is controversial but has to be avoided. Many studies support the fact that PPM has a negative impact on short and long term survival. In order to avoid PPM, aortic root enlargement may be performed. Alternatively a...

BACKGROUND The aim of this study is to see how the sutureless, stentless, Perceval S aortic valves behave when implanted in elderly patients with small aortic root and the comparison with a second group of patients with similar characteristics where a conventional stented bioprosthesis was implanted. This is a prospective randomized institutional study. METHODS Our material is composed from 2...
متن کاملMinimally invasive aortic valve replacement using the Perceval S sutureless valve.
The term “sutureless aortic valve” (su-AV) describes a type of valve which facilitates anchoring of bioprostheses in the aortic position without use of conventional sutures. Although all valve prostheses used for transcatheter aortic valve implantation or replacement (TAVI or TAVR) follow the same principle, they are implanted by wire-based techniques as opposed to su-AVs, which are implanted b...

OBJECTIVE The aim of this study was to report for the first time the phenomenon of thrombocytopenia associated with the use of sutureless aortic valve replacements (AVR), and try to find an explanation for its occurrence. METHODS The data was collected retrospectively for all patients who had sutureless AVR (7 patients) and was compared to patients who underwent sutured AVR (22 patients) by t...
