摘要： A jacket for placement over a heart to constrain congestive heart failure related expansion includes a biocompatible fabric formed into a pouch having a base end and an apical end with an interior of the pouch sized to receive a patient's heart. The base end has a peripheral edge defining a base opening sized to pass an apex of the heart through the base opening. The heart is slipped into the interior of the pouch with the apical end facing the apex of the heart and with the base end facing toward a base of the heart. At the base end, the fabric is folded over for the peripheral edge to have at least a double layer of the fabric. The double layer terminates at a free edge on an outer surface of the pouch and is spaced from the peripheral edge. In an additional embodiment, the fabric includes a side edge of opposing fabric surfaces extending from the apical end to the base end. The opposing fabric surfaces are joined by a stitch assembly. The stitch assembly includes a first stitch line spaced from free edges of the surfaces to define a junction of the fabric surfaces. The free edges are folded back onto the fabric surfaces to define at least a double layer of fabric on opposite sides of the junction. A second stitch line is placed over the junction and through the double layers on the opposite sides of the junction.
