Abstract:
OBJECTIVES:To evaluate rate, recurrence, and predictors of gastrointestinal bleeding (GIB) and impact of endoscopy in left ventricular assist device (LVAD) patients. METHODS:This is a cohort study of all patients who received the current-generation continuous-flow HeartMate II LVAD from 2005 to 2013 at our institution. Patients were followed up, and GIB events recorded until death, time of heart transplantation, or end of observation. RESULTS:LVAD was implanted in 112 patients (median age 67 years, 88% male). A total of 44 patients (39%) had 74 GIB events occurring at a rate of 42.9 per 100 p-y. Endoscopy was performed in 77% of patients, and GIB source was identified in 57% with upper GIB found in almost two-third of cases. Right ventricular dysfunction and post-LVAD ejection fraction >30% were associated with higher GIB rates. Higher pulsatility index was associated with lower GIB rates. Re-bleeding occurred in 19 (43%) patients at a rate of 62.5 per 100 p-y and was not affected by endoscopic therapy at the index endoscopy. CONCLUSIONS:GIB in LVAD patients is common, occurring primarily in the upper GI tract. Upper endoscopy is the preferred strategy though lower endoscopy is also recommended for a full workup. Endoscopy can identify GIB lesions in about 50% of patients, but re-bleeding is common. Right ventricular dysfunction and post-LVAD ejection fraction >30% are associated with higher GIB rates. Higher pulsatility index is associated with lower GIB rates. Reduction in pump speed is a potential strategy for managing and preventing GIB.
