BiVAD, biventricular assisted device; W, warfarin; UFH, unfractionated heparin; +, additional anticoagulant added; >, dose increase; <, dose decrease; OHT, orthotopic heart transplant; GI, gastrointestinal. Interpretation guidelines for aspirin responsiveness: WBAAA cutoff <4 ohms; TPM cutoff for MAAA <50 mm. The range for a normocoagulable state (free from thrombotic events) for patients with HM II and HW devices should be maintained at a CI value ≤1.5, whereas patients on TAH devices should be maintained at a value ≤1.2.
