Coronary Artery Dissection in the Left Main Treated with Stenting in a Patient with Multiple Re-infarction – Case Report

Open access


Introduction: In complex cases of multiple coronary artery stenosis, revascularization strategy could be essential for improving the life expectancy and quality of life. However, major complications are sometimes encountered during interventions, such as rupture of the atheromatous plaque with consequent dissection of the coronary artery, causing an acute coronary syndrome which requires immediate intervention from the operator. In the absence of an experienced interventional cardiologist a complication like this can be fatal.

Case presentation: We present the case of a 67-years old patient, male, with a known history of cardiovascular disease, who presented in our service complaining of chest pain with tightening character, irradiation in the shoulder and left arm, respectively shortness of breath and fatigue. The patient presented a history of multiple infarctions, intervention and stenting on RCA and circumflex artery. Computed Tomographic Coronary Angiography provided detailed information on the location of the target lesions and was followed by a revascularization procedure. However, despite the complex pre-interventional assessment, while trying to engage the guide in the emergence of the circumflex artery, atherosclerotic plaque rupture occurred, causing a dissection of the coronary wall which extended retrogradely into the left main, requiring a rapid response from the operator. A coronary stent was implanted into the left coronary artery trunk, treating the dissection.

Conclusions: Coronary artery dissection is a very serious complication that can occur during a complex revascularization procedure, requiring immediate intervention in order to save the patient’s life.
