We report a case of pseudoaneurysm formation after implantation of Medtronic Freestyle stentless bioprosthesis with a full root technique. A 65-year-old man previously underwent aortic root replacement with a Freestyle bioprosthesis. Ten years after the initial operation, pseudoaneurysm of the aortic root with a diameter of 6 cm was observed by computed tomography. At the reoperation, there was no sign of infective endocarditis, and the pseudoaneurysm was found to originate from the ruptured left and noncoronary sinuses...

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...

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...

In 1977, Karl Viktor Hall implanted a novel tilting disc heart valve prosthesis at Rikshospitalet in Oslo, Norway. The Medtronic-Hall valve was known for its excellent durability and low thrombogenicity. Hall popularized the use of the great saphenous vein in situ as an arterial shunt in the 1960s, made a metal stripper to lyse vein valves, and introduced electromagnetic flowmeters in vascular surgery. He performed the first coronary artery bypass graft in Scandinavia in 1969. Under his leadership the first heart transplantation and the first heart-lung transplantation were performed in Scandinavia by his successor Tor Frøysaker in 1983 and 1986, respectively...

: Transcatheter aortic valve implantation (TAVI) and balloon aortic valvuloplasty (BAV) are now well established percutaneous procedures. These procedures almost always require bursts of rapid ventricular pacing to temporarily reduce cardiac output to facilitate the procedure, usually done via a temporary pacing wire inserted into the right ventricle. We describe a case series of 132 cases of TAVI and 76 BAV done using ventricular pacing via the left ventricular lead by simply connecting one electrode to the patient's skin and one electrode through the left ventricular (LV) wire...

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

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...
