Ventricular free wall rupture with subsequent fluid accumulation in the pericardial sac Ventricular free wall rupture and subsequent cardiac tamponade are life-threatening emergencies. Manifestations of cardiac tamponade include dyspnea, chest pain, hypotension, jugular venous distension, pulsus paradoxus, and faint heart sounds upon auscultation. New-onset cardiac arrhythmia that abolishes the atrial kick Cardiac arrhythmias are common post-MI complications, but the patient's signs and symptoms are not suggestive of cardiac arrhythmias. Autoimmune process that causes fibrinous pericarditis Dressler syndrome is an autoimmune process that causes fibrinous pericarditis. Post-procedural stent thrombosis Post-procedural stent thrombosis is a complication of percutaneous interventions (PCI). The patient's symptoms and signs are strongly suggestive of a pericardial disease rather than a coronary disease. Pathology A 63-year-old man presents to the emergency department with severe chest pain and dyspnea. Following rapid work-up, the diagnosis of myocardial infarction (MI) is made. The patient undergoes appropriate management and is then discharged home. The patient returns 5 weeks later to the emergency department with complaints of a new-onset, low-grade fever associated with persistent chest pain that radiates to the back and relieved by leaning forward. Cardiac auscultation is remarkable for friction rub. Which of the following pathological processes is responsible for this patient’s rehospitalization?
