Heartfelt struggles: When ablation brings the squeeze

Pericarditis frequently occurs as a complication following pulmonary vein isolation (PVI) for atrial fibrillation (AF), yet it seldom progresses to constrictive pericarditis (CP). The diagnosis of constrictive pericarditis is often challenging owing to nonspecific signs and symptoms. Nevertheless, a high level of suspicion and prompt diagnosis offer an ultimate cure. We present a case of a 65-year-old patient who developed chronic pericarditis following PVI. This instance underscores the importance of promptly identifying this complication within this particular group of patients.
