Abstract Background Acute post-ablation pericarditis is the most common complication of epicardial ablation of ventricular arrhythmias (VA), while regional pericarditis following an initially uneventful endocardial catheter ablation (CA) procedure is a rare and elusive diagnosis. Case summary We report a case of a 66-years old Russian female who developed chest pain accompanied by ECG changes—biphasic T waves in V1-V4 leads after an initially uncomplicated premature ventricular complex (PVC) CA procedure. After examination and investigations, including transthoracic echocardiography (TTE), cardiac magnetic resonance imaging (CMR) and cardiac computed tomography (CCT), she was diagnosed with regional pericarditis, which occurred even though the ablation was uneventful with the limited number of radiofrequency applications. Furthermore, the diagnosis was difficult due to normal body temperature and the absence of pericardial effusion and myocardial abnormalities on TTE, findings that are not characteristic of pericarditis. The patient's last office visit was in six months after the procedure. Neither patient had any complaints, nor there were any changes on ECG and TTE. Discussion Regional post-ablation pericarditis is a relatively rare type of postcardiac injury syndrome (PCIS). The varying severity of the PCIS clinical course makes the diagnosis of post-ablation pericarditis initially difficult, especially in patients undergoing an uneventful catheter ablation procedure. Non-invasive imaging modalities as cardiac magnetic resonance imaging (CMR) and cardiac computed tomography (CCT) should be considered initially in elusive cases of PCIS.
