Acute clinical deterioration in a patient with end-stage dilated cardiomyopathy and left ventricular thrombus
1Department of Pediatric Cardiology, University Children's Hospital, Vienna, Austria.
Insights
This case report highlights the successful use of mechanical circulatory support with a left ventricular assist device (LVAD) in a young patient with severe dilated cardiomyopathy and left ventricular thrombus. Emergency LVAD therapy offered a life-saving option for this critical patient.
Area of Science:
- Cardiology
- Cardiovascular Surgery
- Medical Devices
Background:
- Dilated cardiomyopathy is a severe heart condition leading to heart failure.
- Large left ventricular thrombus formation poses a significant risk of systemic embolism.
- End-stage heart failure often requires advanced therapeutic interventions.
Observation:
- A 17-year-old male presented with end-stage dilated cardiomyopathy and a large left ventricular thrombus.
- The patient underwent emergency thrombectomy and partial left ventriculectomy (Batista procedure).
- A left ventricular assist device (LVAD) with a centrifugal nonocclusive pump was implemented.
Findings:
- The patient demonstrated successful recovery with the LVAD system.
- Mechanical support was withdrawn on Day 9 post-implantation.
- The patient was discharged on Day 19, indicating a positive outcome.
Implications:
- Emergency mechanical circulatory support can be effective in patients with extremely poor prognoses.
- LVADs offer a viable treatment option for selected patients with dilated cardiomyopathy and LV thrombus.
- This case underscores the importance of timely and advanced interventions in managing critical cardiovascular conditions.
Abstract:
The case of a 17-year-old male patient with severe end-stage dilated cardiomyopathy and a large thrombus formation within the cavum of the left ventricle is reported. After an acute thrombectomia combined with a partial left ventriculectomy (Batista procedure), the patient was successfully treated with an appropriate left ventricular assist device (LVAD) system using a centrifugal nonocclusive pump (Biomedicus, Medtronic, Anaheim, CA, U.S.A.). Mechanical support was removed on Day 9, and the patient was discharged from the hospital on Day 19. The effectiveness of emergency mechanical support in patients with very unfavorable prognoses is discussed.
