Unilateral Pulmonary Edema after Minimally Invasive Cardiac Surgery: A Case Report

Area of Science:

• Cardiology
• Thoracic Surgery
• Critical Care Medicine

Background:

• Unilateral pulmonary edema post-minimally invasive cardiac surgery is uncommon and its etiology is not fully understood.
• Recurrent left atrial myxoma necessitates surgical intervention, posing potential risks.
• Minimally invasive cardiac surgery techniques aim to reduce morbidity but can present unique challenges.

Observation:

• A patient developed severe unilateral pulmonary edema after undergoing redo-resection of recurrent left atrial myxoma via right mini-thoracotomy.
• The condition manifested despite the minimally invasive approach.
• Management involved advanced respiratory and circulatory support strategies.

Findings:

• Successful treatment of aggressive unilateral pulmonary edema was achieved using intraoperative veno-venous extracorporeal membrane oxygenation and postoperative dual-lumen endotracheal tube ventilation.
• The patient recovered fully and was discharged without complications.
• This case provides insight into managing a rare but severe postoperative complication.

Implications:

• This case underscores the importance of vigilant monitoring for unilateral pulmonary edema in cardiac surgery patients.
• Advanced extracorporeal membrane oxygenation and ventilation techniques can be crucial for managing severe postoperative respiratory failure.
• Further research into the specific mechanisms causing unilateral pulmonary edema after cardiac surgery is warranted.
