spontaneous coronary artery dissection

Shams Y-Hassan
Spontaneous coronary artery dissection (SCAD) and takotsubo syndrome (TS) are two cardiovascular syndromes with predilection for women. Both conditions may be preceded by an emotional stress or, for the affected individual, an unusual severe physical exercise. "Restitution ad integrum" occurs in most cases suffering from SCAD or TS with complete angiographic resolution of the dissected vessel and left ventricular dysfunction respectively. Recently, many cases, which were initially diagnosed as TS because of typical left ventricular ballooning pattern showed to have SCAD, have been reported; these cases were deemed to be "SCAD misdiagnosed as TS"...

Spontaneous coronary artery dissection is a nonatherosclerotic etiology of acute coronary syndrome, including sudden cardiac death, which frequently affects younger women. This review highlights contemporary knowledge regarding spontaneous coronary artery dissection demographics, prevalence, diagnosis, presentation, and associated conditions and risks, inpatient treatment, major adverse clinical events, and outpatient management decisions.

Blunt chest trauma can cause a wide variety of injuries including acute myocardial infarction (AMI). Although AMI due to coronary artery dissection caused by blunt chest trauma is very rare, it is associated with high morbidity and mortality. In the vast majority of patients with AMI, primary percutaneous coronary interventions (PCI) are performed to recanalize obstructed arteries, but PCI carries a substantial risk of hemorrhagic complications in the acute phase of trauma. We report a case of AMI due to right coronary artery (RCA) dissection caused by blunt chest trauma...

We present two cases of spontaneous left main stem coronary artery dissection. One was underdiagnosed with suboptimal percutaneous coronary artery intervention followed by acute vessel occlusion again during the hospitalization. The other one was identified and confirmed by intravascular ultrasound, followed by conservative medical treatment, with completed healing of SCAD during two-month follow up.

Spontaneous coronary artery dissection (SCAD) has emerged as an important cause of acute coronary syndrome, myocardial infarction, and sudden death, particularly among young women and individuals with few conventional atherosclerotic risk factors. Patient-initiated research has spurred increased awareness of SCAD, and improved diagnostic capabilities and findings from large case series have led to changes in approaches to initial and long-term management and increasing evidence that SCAD not only is more common than previously believed but also must be evaluated and treated differently from atherosclerotic myocardial infarction...

Cardiac emergencies in pregnancy and the postpartum period are rare but often life-threatening. An emergency physician's differential diagnosis for chest pain in the peripartum patient often includes serious etiologies such as pulmonary embolism or myocardial infarction (MI). A lesser-known but important consideration on the differential for MI is that of a spontaneous coronary artery dissection (SCAD). SCAD is defined as an intramural hematoma within the coronary artery that compresses the true lumen. Expansion by increased pressures may lead to subsequent myocardial ischemia and infarction...

We report a case of percutaneous coronary intervention for spontaneous multi-vessel coronary dissection including the left main coronary artery. This case suggests that intracoronary imaging is useful for understanding the complex anatomy and for choosing the appropriate management for effective revascularization. Furthermore, cutting balloon angioplasty prior to stenting is useful for preventing the longitudinal extension of the intramural hematoma and avoiding unnecessary stent implantation.

Spontaneous coronary artery dissection (SCAD) is an uncommon cause of acute coronary syndrome (ACS) or sudden death, which typically affects young women. We reported two cases of black Africans patients, aged 56 and 52 years old, who presented to Abidjan Heart Institute for ACS. Coronary angiography showed spontaneous dissection of the right coronary artery in the first case, and dissection of the distal left anterior descending artery in the second. A conservative approach was preferred. Both patients received antiplatelet agents, beta-blockers, angiotensin converting enzyme inhibitors and statins, with a favorable in-hospital course...

Purpose To evaluate the frequency and implications of perivascular fat stranding on coronary computed tomography (CT) angiograms obtained for suspected acute coronary syndrome (ACS). Materials and Methods This retrospective registry study was approved by the institutional review board. The authors reviewed the medical records and images of 1403 consecutive patients (796 men, 607 women; mean age, 52.8 years) who underwent coronary CT angiography at the emergency department from February 2012 to March 2016. Fat attenuation, length and number of circumferential quadrants of the affected segment, and attenuation values in the unaffected epicardial and subcutaneous fat were measured...

RATIONALE: Iatrogenic acute aortic dissection (IAAD) induced by cardiac surgery is a fatal complication, with 0.04% of therapeutic procedures and worse outcomes than spontaneous aortic dissection. PATIENTS CONCERNS: A 64-year-old male complaining of intermittent chest tightness for 4 years received an off-pump coronary artery bypass grifting (OPCABG) and IAAD was found during surgery. DIAGNOSIS: Unstable angina, coronary artery triple vessel lesion, IAAD...

Pregnancy-related spontaneous coronary artery dissection (P-SCAD) is a rare but life-threatening condition of the peripartum and postpartum mother. The gold standard of diagnosing P-SCAD is a left cardiac catheterization; however, this diagnostic tool may not be used early because myocardial infarction is not typically a top differential diagnosis for women and especially young pregnant women presenting with acute chest pain. Providers and registered nurses, particularly those in the prehospital setting, the emergency department, and labor and delivery units, should be aware of signs, symptoms, potential risk factors, and diagnostic results that could indicate P-SCAD and initiate early and appropriate treatment to improve maternal outcomes...

BACKGROUND: The coronary computed tomography angiography features of acute spontaneous coronary artery dissection, an important cause of acute coronary syndrome in young women, have not been assessed. METHODS: The "Virtual" Multicenter Mayo Clinic Spontaneous Coronary Artery Dissection Registry was established in 2010 and includes retrospective and prospective patient data. Retrospective assessment of acute coronary computed tomography angiography images was performed for 14 patients (16 vessels) who had images performed within two days of invasive coronary angiography diagnosis of acute spontaneous coronary artery dissection...

Background Spontaneous coronary artery dissection is a rare non-atherosclerotic cause of acute coronary syndromes, often underdiagnosed based on standard coronary angiography. Moreover, features, presentation, and intravascular imaging of recurrent spontaneous dissections have not been assessed. Methods Patients with recurrent spontaneous coronary artery dissection, who were admitted to our catheterization laboratory over a 10-year period, were identified. Demographic, clinical, angiographic, and intravascular imaging data were reviewed and analyzed, comparing patients with a single event with those who had a recurrence...

Acute Coronary Syndrome (ACS) is a common diagnosis in the emergency department (ED), the most severe manifestation of which is ST elevation on electrocardiogram (ECG). ST elevation reflects obstruction of flow through the coronary arteries, most commonly due to coronary atherosclerotic plaque rupture. However, alternative causes of coronary obstruction causing ST elevation are possible. Spontaneous coronary artery dissection (SCAD) is an unusual cause of ST elevation in ED patients which providers may encounter in patients without traditional atherosclerosis risk factors...

Spontaneous coronary artery dissection (SCAD) is a rare entity that can cause acute myocardial infarction and sudden cardiac death (SCD) which often goes unrecognized. We report a case of SCAD in a young postpartum female who presented with sudden cardiac arrest. The patient was managed medically and found to have fibromuscular dysplasia (FMD). After being stabilized in the critical care unit, coronary angiography was performed which showed dissection of the left main artery, intramural hematoma, and the culprit lesion...
