PSEUDO-DISSECTION IN PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY

Percutaneous transluminal coronary angioplasty (PTCA) is a well-establ ished and effective treatment modality for significant coronary artery disease. Because it enlarges the arterial lumen by plaque disruption, minor wall dissection is not infrequent. Complex dissections are, how ever, uncommon but may lead to acute vessel closure with its attendant major clinical morbidity and mortality. We describe here a case of ps eudo-dissection and its potential for misinterpretation and subsequent inappropriate management.
