Insights
Low-dose thrombolytic therapy using recombinant tissue-type plasminogen activator (rt-PA) successfully dissolved a left ventricular thrombus in a patient unsuitable for surgery. This approach offers a potential alternative for managing left ventricular thrombi.
Area of Science:
- Cardiology
- Vascular Medicine
- Pharmacology
Background:
- Management of intracardiac mural thrombi lacks a clear consensus.
- Left ventricular thrombi can lead to severe complications such as systemic embolism.
Observation:
- A 59-year-old male presented with symptoms indicative of peripheral artery occlusion.
- Echocardiography revealed severe left ventricular systolic dysfunction and a mobile left ventricular apical thrombus.
- Surgical intervention was deemed high-risk for the patient.
Findings:
- Slow infusion of low-dose recombinant tissue-type plasminogen activator (rt-PA) was administered.
- Serial echocardiograms demonstrated a significant reduction in thrombus size during rt-PA infusion.
- Complete thrombus lysis was achieved within 24 hours of rt-PA therapy.
Implications:
- Low-dose, slow-infusion rt-PA may represent a viable therapeutic option for left ventricular thrombi.
- This strategy could be particularly beneficial for patients with high surgical risks.
- Further research is warranted to establish the safety and efficacy of this treatment modality.
Abstract:
There is no consensus on the management of intracardiac mural thrombi. A 59-year-old man underwent echocardiographic examination for right leg pain and pulse deficits in the right lower extremity, which showed severe left ventricular systolic dysfunction and a bell-shaped protruding mobile thrombus in the left ventricular apex. Due to high risk of surgery, 50 mg recombinant tissue-type plasminogen activator (rt-PA) was slowly infused over eight hours. Serial echocardiographic examinations showed a progressive decrease in the size of the thrombus within the first hours of rt-PA infusion, resulting in complete lysis after 24 hours. Low-dose and slow-infusion thrombolytic therapy may be an alternative therapy for left ventricular thrombi when surgery is not feasible.
