BACKGROUND: The clinical characteristics of @entity1165 ( @entity1165 ), when it develops after valve surgery, have not been described. METHODS AND RESULTS: Between 1985 and 1996, 31 @entity1 (30 @entity1 and 1 @entity1 ) who had undergone valve surgery were found to have inducible @entity1165 . Nine @entity1 (29%) had sustained VT due to bundle-branch reentry (BBR) (group 1). Four of these @entity1 had normal left ventricular function, and VT with a right bundle-branch morphology was inducible in 4 @entity1 . Group 2 included 20 @entity1 with inducible myocardial (ie, non-BBR) VT. @entity453 was present in 15 group 2 @entity1 (75%) due to @entity731 (n=12) and nonatherosclerotic (n=3) causes. Two @entity1 had both inducible sustained BBR and @entity296 (group 3). Sustained BBR VT occurred significantly earlier after valve surgery (median, 10 days) than the onset of postoperative @entity296 (median, 72 months; P<.005). CONCLUSIONS: Myocardial VT was the most common type of inducible @entity1165 in @entity1 with @entity340 . The majority of these @entity1 had underlying @entity453 and significant @entity1002 . However, in almost one third of the @entity1 , sustained BBR VT was the only type of inducible @entity1165 . This type of VT was facilitated by the valve procedure occurring within 4 weeks after surgery in most @entity1 . In these @entity1 , left ventricular function was relatively well preserved, and the right @entity5036 type of BBR was frequently induced. Because a curative therapy can be offered to these @entity1 (ie, @entity5036 ), BBR should be seriously considered as the mechanism of VT in @entity1 with @entity340 , particularly if the @entity943 occurs soon after valve surgery.
