Large right atrial thrombus with pulmonary embolism

Area of Science:

• Cardiology
• Vascular Medicine
• Critical Care Medicine

Background:

• Right atrial thrombi are rare but serious conditions, often associated with significant morbidity and mortality.
• Pulmonary embolism (PE) can arise from thrombi in the right heart, leading to acute cardiopulmonary compromise.
• Prompt diagnosis and effective treatment are crucial for improving patient outcomes.

Observation:

• Two patients, aged 67 and 77, presented with severe symptoms including progressive dyspnea and syncope.
• Both individuals were diagnosed with large right atrial thrombi complicated by pulmonary embolism.
• Clinical presentation varied, necessitating distinct therapeutic approaches.

Findings:

• The first patient, treated with recombinant tissue plasminogen activator (thrombolysis), experienced a full recovery without complications.
• The second patient underwent operative thrombectomy and heparin therapy but unfortunately succumbed to pulmonary infarction.
• These contrasting outcomes highlight the potential benefits and risks associated with different treatment modalities.

Implications:

• Limited data suggest thrombolytic therapy warrants consideration for right heart thrombi with pulmonary embolism.
• Further research is needed to establish optimal treatment guidelines for this patient population.
• Early consideration of thrombolysis could potentially improve survival rates in selected cases.
