Dry tamponade is a rare complication of percutaneous coronary intervention. It encompasses a heterogenous pathophysiology and is used to describe hemodynamic compromise secondary to a coronary artery perforation, without free-flowing fluid in the pericardium. Tamponade physiology can result from compressive epicardial, intramyocardial, subepicardial hematomas, or dissecting intramyocardial hematomas. The diagnosis of dry tamponade requires hemodynamic derangement in the context of a compressive hematoma as demonstrated by imaging. Although echocardiography can often help identify dry tamponade, additional studies including right heart catheterization, computed tomography, or cardiac magnetic resonance imaging can inform the exact mechanism and help guide management. This article describes a case of dry tamponade, reviews the existing literature on the topic, and offers expert recommendations on diagnosis and management.
