When Rhythm Correction Turns Risky: Rare Right-Sided Haemorrhagic Pleural Effusion Post Maze Procedure

The maze procedure for atrial fibrillation carries risks, including pleural effusion. We report a case of a 54-year-old woman with right-sided pleural effusion post maze surgery, presenting with dyspnoea. Despite treatment, complications arose, including atrial flutter. Prompt recognition and multidisciplinary management led to a favourable outcome. This case underscores the importance of vigilance for rare post-operative complications and highlights the need for collaborative care in optimising patient outcomes following cardiac surgeries. Further research is warranted to refine management strategies for such occurrences.

Healthcare providers should remain vigilant for rare complications, for example right-sided haemothorax, following cardiac surgeries such as the maze procedure to initiate timely management and ensure favourable outcomes.The post-maze procedure, atrial flutter or macroreentrant atrial tachycardia may resist standard medical treatment, emphasising the importance of considering catheter ablation as a therapeutic option to improve patient outcomes.Empowering patients with knowledge about potential post-procedure complications and associated symptoms facilitates early reporting, enabling prompt intervention by healthcare providers and leading to improved treatment outcomes.
