UNFRACTIONATED HEPARIN VERSUS LOW-MOLECULAR-WEIGHT HEPARIN ANTICOAGULANT BRIDGING IN LEFT-SIDED MECHANICAL HEART VALVE PATIENTS: THE HI-LOW STUDY

In anticipation of an invasive procedure with a high bleeding risk, patients with a mechanical heart valve are bridged with either unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH). However, there is no consensus regarding the ideal strategy, and prospective studies are lacking.
