Background: Calcification of the pericardium due to recurrent inflammation is a rare condition which can lead to severe restrictive cardiomyopathy. This case demonstrates severe circumferential pericardial calcification leading to cardiogenic shock and death. It is proposed that the patient's history of repeat cardiac interventions, including cardiac ablation, and open valve repair procedures precipitated this.Case Presentation: 78-year-old Caucasian man presented for syncope, dyspnea on exertion, and chest pain. Past medical history significant for atrial fibrillation, requiring cardiac ablation procedures, along with severe mitral regurgitation requiring open valve replacement, He was found to have severe restrictive cardiomyopathy in the setting of a circumferentially calcified pericardium discovered on chest imaging. The patient was transferred to the cardiovascular intensive care unit in cardiogenic shock. Cardiothoracic surgery was consulted, and pericardial stripping procedure was performed. Despite this intervention, the patient developed septic shock and passed away.Conclusions: This case highlights the importance of early identification in patients with risk factors for pericardial calcification, namely, multiple prior cardiac interventions such as open valve replacements, and cardiac ablations. Early diagnosis with radiographic imaging can impact outcomes for patients with this condition.
