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.

干填塞诊断和管理的挑战


干填塞是经皮冠状动脉介入治疗的罕见并发症。它包含异质的病理生理学，用于描述继发于冠状动脉穿孔、心包内没有自由流动液体的血流动力学损害。填塞生理学可由压迫性心外膜、心肌内、心外膜下血肿或解剖性心肌内血肿引起。干性填塞的诊断需要在压迫性血肿的情况下出现血流动力学紊乱，如影像学所示。虽然超声心动图通常可以帮助识别干性填塞，但包括右心导管插入术、计算机断层扫描或心脏磁共振成像在内的其他研究可以告知确切的机制并帮助指导治疗。本文描述了一个干填塞病例，回顾了有关该主题的现有文献，并提供了有关诊断和治疗的专家建议。
