Spontaneous left main coronary artery spasm and intravascular ultrasonography findings
نویسندگان
چکیده
Vasospasm causes an abrupt and temporary occlusion in coronary arteries in patients with normal coronary arteries. Nonetheless, vasospasm of the left main coronary artery is unusual and can be spontaneous or iatrogenic. We herein report a very rare cause of temporary spasm of LMCA, which resulted in vasospastic angina and anginal chest pain. Intravascular ultrasonography should be considered as a good diagnostic tool in revealing the exact etiology of occlusions such as vasospasm or thrombosis.

Spontaneous coronary artery dissection involving the left main stem: assessment by intravascular ultrasound.
This case report describes the devastating consequences of spontaneous coronary dissection in a 36 year old female patient who otherwise had a normal coronary arteriogram. Intravascular ultrasound showed coronary artery dissection and intramural haematoma at the left main stem coronary artery. Acute coronary syndrome developed and subsequently surgical revascularisation was performed successfully.
متن کاملSpontaneous Coronary Artery Dissection Mimicking Coronary Spasm Diagnosed by Intravascular Ultrasonography
Spontaneous coronary artery dissection (SCAD) is a rare and occasionally life-threatening cause of acute coronary syndrome. Patients may present with clinical scenarios ranging from angina pectoris to cardiogenic shock to sudden cardiac death, and it may be a potentially life-threatening condition if not recognized. However, its etiology, pathophysiology and optimal therapeutic strategies have ...
متن کاملIntervention on the left main coronary artery. Importance of periprocedural and follow-up intravascular ultrasonography guidance
Periprocedural intravascular ultrasonography guidance for left main coronary artery stenting is well established. However, the role of this tool is also important at follow-up interventions. We present a case of a patient with previous history of left main coronary artery angioplasty. During a recent attempt to treat tight stenosis in the left anterior descending coronary artery, it was not pos...
متن کاملIsolated Left Main Coronary Artery Spasm Detected by Multidetector Computed Tomography
Although atherosclerotic obstruction is the main cause of left main coronary artery (LMCA) disease, it can also be associated with vasospasm. We report a case of a 61-year-old male who presented with ostial stenosis of the LMCA, detected by 64-slice multi-detector computed tomographic coronary angiography (MDCT-CA). Careful review of MDCT and intravascular ultrasound findings showed suspicion o...
متن کاملTreatment of Spontaneous Left Main Coronary Artery Spasm with a Drug-Eluting Stent
Variant angina due to spontaneous left main trunk spasm is rarely reported in the literature. Despite intensive medical treatment or surgical intervention, patients may still suffer from recurrent symptoms. We describe a 70-year-old male patient who had spontaneous left main coronary artery spasm with recurrent angina. The patient was successfully treated with a drug-eluting stent and remained ...
