Insights
Gross hematuria is a rare but serious bleeding complication in patients with continuous-flow left ventricular assist devices (CF-LVADs). Avoiding urinary tract trauma is crucial to prevent this adverse event.
Area of Science:
- Cardiology
- Urology
- Medical Devices
Background:
- Patients with continuous-flow left ventricular assist devices (CF-LVADs) face an elevated risk of bleeding complications.
- Gastrointestinal (GI) bleeding is the most frequently reported mucosal bleeding site in CF-LVAD patients.
- Urinary tract bleeding is a less common but potentially severe complication.
Purpose of the Study:
- To review institutional experience with urinary tract bleeding (gross hematuria) after CF-LVAD implantation.
- To quantify the impact of gross hematuria on hospital resource utilization.
- To compare hematuria complications with GI bleeding in CF-LVAD patients.
Main Methods:
- Retrospective review of patient records undergoing CF-LVAD implantation (October 2011 - April 2015).
- Identification and analysis of major adverse events, specifically gross hematuria and GI bleeding.
- Comparison of patient demographics and hospital course, including length of stay and readmission rates.
Main Results:
- Gross hematuria occurred in 8.6% of patients and 5.1% of hospitalizations.
- Severe hematuria was associated with urethral catheterization, urinary retention, or urologic surgery.
- Hospitalizations for hematuria were less frequent but 3.2 times longer than for GI bleeding (17.0 vs. 5.3 days).
- Late recurrent gross hematuria occurred in all cases, leading to readmission.
Conclusions:
- Gross hematuria is an infrequent yet morbid bleeding complication in CF-LVAD recipients.
- Preventive strategies should focus on avoiding traumatic urethral catheterization and urinary retention.
- Careful management of the urinary tract is essential in high-risk CF-LVAD patients.
Abstract:
Patients with continuous-flow left ventricular assist devices (CF-LVADs) are at increased risk of bleeding. We reviewed our institutional experience with bleeding in the urinary tract after CF-LVAD implantation and quantified the impact on hospital resource utilization in comparison with bleeding in the gastrointestinal (GI) tract, the most commonly reported mucosal site of bleeding after LVAD implantation. Records were retrospectively reviewed for patients undergoing CF-LVAD implantation at our institution between October 2011 and April 2015. Major adverse events of gross hematuria and GI bleeding were identified, and patient demographics and hospital course were reviewed. Gross hematuria occurred in 3 of the 35 patients (8.6%) and in 5.1% of all hospitalizations for CF-LVAD patients. Severe hematuria occurred after traumatic urethral catheterization, urinary retention, or urologic surgery. Hospitalization for hematuria was six times less likely than hospitalization for GI bleeding; however, hematuria hospitalizations lasted 3.2 times longer than GI bleeding hospitalizations (17.0 vs. 5.3 days). Late recurrent gross hematuria occurred in all cases, with rehospitalization occurring after 109 ± 53 days. In conclusion, gross hematuria is an infrequent but morbid bleeding complication in CF-LVAD patients. Strategies to avoid this complication include strict avoidance of traumatic urethral catheterization and urinary retention in high-risk patients.
