Hancock® Bioprosthetic Valved Conduits consist of a porcine aortic valve sutured into the center of a woven fabric conduit. The Hancock conduits are recommended for reconstruction of congenital or acquired cardiac and great vessel malformations or pathology.

These valved conduits are not intended for aortic root replacement.

Because the Hancock valved conduit does not incorporate a stent, the ratio of conduit outer diameter to inner diameter of the bioprosthesis is optimized.

The Hancock valved conduit is available in a wide range of sizes and models. Features include:

The Hancock II porcine bioprosthesis (Medtronic Inc., Minneapolis, MN, USA) is a second-generation device with a low pressure fixation porcine valve that is mounted on a Delrin stent, which can be deflected without compromising the valve.

Our long-term experience with the Hancock bioprosthesis confirms that this valve's durability is limited. Therefore, we believe that the indications for the use of porcine bioprostheses should be restricted, until consistent data become available concerning the durability of the new generation of prosthetic valves.

The Medtronic Mosaic bioprosthesis is a third-generation valve made of porcine (pig) tissue. The tissue is attached to a cloth-covered, flexible plastic frame, called a stent. The bioprosthesis is then sewn into place where the patient’s diseased valve used to be.

The Hancock II valve bioprosthesis (Hancock II; Medtronic, Inc Minneapolis, Mn) was commercialized in1982. It is a porcine bioprosthesis fixed at low pressure in glutaraldehyde (0.625%) to preserve the natural collagen crimping, treated with a calcium-retarding agent (T6 sodium dodecyl sulphate), and mounted on a low-profile Delrin stent (Dupont, Wilmington, Del) . Excellent long-term durability has been showed especially in the aortic position .

A 52-year Caucasian woman, operated for the first time in 1965 for complete atrio-ventricular canal, underwent in 1983 mitral and tricuspid valve replacement with Hancock II porcine bioprostheses for advanced rheumatic valve disease. In 1988, the mitral bioprosthesis was replaced by a St Jude mechanical valve because of structural valve deterioration due to excessive calcification. The patient did well for over 25 years, until the beginning of 2013 when she experienced shortness of breath and presented an important lower limb oedema. Patient’s dyspnoea progressed to a NYHA functional class IV with development of right heart failure, pleural effusions and ascitis. Trans-thoracic (TTC) and trans-oesophageal (TEE) echocardiography revealed severe deterioration of the tricuspid bioprosthesis with a IV/IV regurgitation surprisingly without any calcification of the free-moving leaflets. By contrast, the papillary muscles were completely immobilized and severely calcified (), thus creating a kind of tunnel downstream the valve with an important intra-ventricular pressure gradient. The pre-operative coronary angiography was normal. At the fourth reoperation in September 2013, the explanted prosthesis showed holes and tears in all leaflets with no signs of calcification other than at the level of the commissures. By contrast extensive pannus proliferation surrounded the whole external clot surface even covering the edges of the calcified papillary muscles fused to the leaflets at all three commissures with a severe creep stenosis of the struts (). The calcified papillary muscles were excised and the tricuspid xenograft was replaced by another 31 mm bioprosthesis. Patient recovered uneventfully and remained asymptomatic at 1-year follow-up.
