Transesophageal echocardiography (TEE) guided early cardioversion (CV) in conjunction with short-term anticoagulation has been shown to be safe, and an alternative to prolonged conventional anticoagulation therapy. Recently, low molecular weight heparins (LMWHs) have been used successfully as an alternative to standard heparin therapy obviating the need for hospitalization and APTT monitoring. The aim of this study was to determine the feasibility and safety of TEE guided early cardioversion in conjunction with short-term LMWH use in @entity1 with @entity955 ( @entity955 ). The study group consisted of 172 consecutive @entity1 with @entity955 . Before TEE, 90 @entity1 received LMWH (Dalteparin 2 x 5,000U) and 82 @entity1 received standard heparin (UFH) (5,000U bolus followed by infusion to raise APTT to 1.5 times control). TEE was performed and the left atrium and left @entity955 were examined thoroughly for the presence of @entity715 . One @entity1 from each group was excluded due to detection of a left @entity715 by TEE. Immediately after TEE, CV was attempted and @entity1229 was initiated. All @entity1 received @entity1229 for one month after CV. In the LMWH group, 89 of 90 @entity1 (98.9%) were successfully cardioverted. CV was successful in 97.5% of the @entity1 in the UFH group. None of the @entity1 experienced @entity1031 events during the four weeks after CV. TEE guided early CV in conjunction with short-term LMWH treatment is as safe as UFH for the prevention of @entity1031 events after CV.

The safety of low-molecular weight heparins for the prevention of XXXX events after cardioversion of @entity955 .
