Filter by:Spontaneous Coronary Artery Dissection (SCAD) is a rare and often misdiagnosed cause of Acute Coronary Syndrome (ACS) affecting predominantly young women without cardiovascular risk factors. The origin of SCAD remains uncertain but a strong and frequent association with Fibromuscular Dysplasia (FMD) has been recently reported based on imaging evidence only. The aim of our study is to assess the presence of FMD and its genetic determinants i in a sample for haematoma or spontaneous coronary artery dissection. From May 2016 to 2018 we plan to include prospectively and retrospectively 200 patients admitted for ACS with confirmed diagnosis of SCAD. This study will be conducted in more than 30 French interventional cardiology centers. Coronary angiograms or intracoronary imaging data will be reviewed by two experienced interventional cardiologist experts in SCAD diagnosis. For each patient a genetic analysis will be performed. A systematic screening for FMD will be realized by computed tomographic or MRI angiography of renal, cerebrovascular and iliac arteries and reviewed by two experienced radiologists. A one year follow-up is expected. This study aims to confirm the presumed association of FMD and SCAD through the exploration of several artery beds and the study of confirmed genetic determinants, which has never been described previously to our knowledge.
The anomalous origin of right coronary artery (RCA) is a rare coronary anomaly. Recently, the detection of this anomaly has been more frequent as the use of cardiac multidetector computed tomography has become more popular. It can cause myocardial ischemia, syncope and sudden cardiac death. Surgical repair is generally recommended for symptomatic patients. However, there is controversy concerning the proper evaluation and treatment strategy for patients without documented myocardial ischemia. The stenotic lesion of anomalous origin of RCA will be assessed by fractional flow reserve (FFR).
