Coronary heavy calcification (HC) poses a sturdy challenge to percutaneous coronary intervention (PCI). Scores considering calcification length, thickness, or circumferential extent, are widely accepted to dictate upfront calcium modification to improve PCI outcomes. Although often marginalized, calcification shape (morphology) may require consideration during procedure planning in selected cases. This case demonstrates how a focal but spur-shaped calcification led to a massive proximal left anterior descending (LAD) dissecting intramural hematoma.
冠状动脉重度钙化（HC）给经皮冠状动脉介入治疗（PCI）带来了巨大挑战。目前广泛接受的观点是，通过评估钙化长度、厚度或周向范围等指标，对钙化进行预处理，以改善 PCI 预后。尽管在某些情况下可能会被忽视，但在制定手术方案时，钙化形态（形态学）也需要考虑。本病例展示了一处局限性但呈刺状的钙化如何导致左前降支（LAD）近端巨大的内膜下血肿。
