Sutureless Prosthesis for Aortic Aneurysms
نویسنده
چکیده
The device consists of four parts (Fig 1). The disposable mouthpiece (Inspiron No. 001200) fits into one end of a 6inch corrugated tube (Hudson Corr-A-Tube II, No. 1410). The other end of this tube is coupled to a connector (BardParker oxygen hose connector No. 5002) via a 22 X 22-mm adapter (Bard-Parker No. 5095). This connector fits snugly onto the male hub of the rubber tubing of most commercially available sphygmomanometers. An 18-gauge needle may be inserted into the adapter to equalize the intraoral and intrabronchial pressures during the strain phase of Valsalva's maneuver.4 The patient in the supine or semirecumbent position blows into the mouthpiece and maintains the column of mercury in the sphygmomanometer at 40 mm for a period of ten seconds. This device is presently being studied in a series of patients.

Sutureless aortic valve replacement.
The increasing incidence of aortic stenosis and greater co-morbidities and risk profiles of the contemporary patient population has driven the development of minimally invasive aortic valve surgery and percutaneous transcatheter aortic valve implantation (TAVI) techniques to reduce surgical trauma. Recent technological developments have led to an alternative minimally invasive option which avoi...

Sutureless Aortic Prosthesis Implantation: the First Brazilian Experience with Perceval Device
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 ballo...

Aortic valve stenosis is the most common valve disease in the western world. Over the past few years the number of aortic valve replacement (AVR) interventions has increased with outcomes that have been improved despite increasing age of patients and increasing burden of comorbidities. However, despite such excellent results and its well-established position, conventional AVR has undergone grea...
متن کاملRecent developments for surgical aortic valve replacement: The concept of sutureless valve technology
Aortic stenosis has become the most frequent type of valvular heart disease in Europe and North America and presents in the large majority of patients as calcified aortic stenosis in adults of advanced age. Surgical aortic valve replacement has been recognized to be the definitive therapy which improves considerably survival for severe aortic stenosis since more than 40 years. In the most recen...
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...
