43 Dressler’s syndrome post left atrial appendage occlusion: a rare diagnoses resurfaces

AbstractThree weeks post-procedure, an 85 year old male developed a new pericardial effusion. Infectious and malignant causes were excluded. Cytology demonstrated mixed inflammatory cells and a diagnosis of DS was made. One-month and six-month clinical review with trans-oesophageal echocardiogram (TOE) showed sustained resolution of the pericardial effusion. DS is a rarely reported complication of LAAO.BackgroundDressler’s Syndrome also known as post myocardial infarction syndrome is a secondary pericarditis that can occur after cardiac myocyte damage. Such damage can occur after a myocardial infarction or routine endovascular surgery. It can present with or without pericardial effusion. DS has a significantly declining incidence due to the improved and more aggressive revascularisation techniques currently in use. This case was an iatrogenic cause via an intracardiac intervention. This intervention was a left atrial appendage occlusion (LAAO) with the AMPLATZER amulet device. LAAO is indicated for patients who are at risk of bleeding and who cannot tolerate long term oral anticoagulation. DS is a rare complication of the LAAO procedure with one study documenting a
