Aortic dissection occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart. In most cases this is associated with a sudden onset of severe chest or back pain, often described as “tearing” in character. Also, vomiting, sweating, and lightheadedness may occur. Other symptoms may result from decreased blood supply to other organs such as stroke or mesenteric ischemia. Aortic dissection can quickly lead to death from not enough blood flow to the heart or rupture of the aorta.

Spontaneous coronary artery dissection, which causes acute coronary syndrome and can result in sudden death, is rare; but its true incidence is underestimated, since most patients die suddenly, without diagnosis. The aim of this study was to show the importance of prompt diagnosis and treatment.
In reviewing the records of 5,000 consecutive patients who underwent coronary angiography between January 2001 and August 2006, we found 6 cases of spontaneous coronary artery dissection (an incidence rate of 0.12%). Five patients presented with left main coronary artery dissection and 1 patient, with right coronary artery dissection.
Angioplasty with stenting failed in the patient with right coronary artery dissection. Coronary artery bypass surgery was performed in all patients. The patient with right coronary artery dissection died of sepsis on the 30th postoperative day. The other 5 patients (83.3%) are still free of symptoms, and they had negative results on stress tests at the 6- and 12-month follow-up visits after coronary artery bypass surgery.
The clinical presentation of spontaneous left main coronary artery dissection was similar to that of atherosclerotic disease. However, early diagnosis of spontaneous coronary artery dissection by means of coronary angiography is of paramount importance, because urgent coronary artery bypass grafting can be lifesaving.
Spontaneous coronary artery dissection (CAD), which causes acute coronary syndrome and can result in sudden death, is a rare event. Spontaneous coronary artery dissection has been observed in 3 groups of patients: patients with coronary artery disease, young women during peripartum, and patients with idiopathic disease and no obvious associated factors. The pathogenesis of spontaneous CAD is still unclear.1,2
The clinical presentation of left main coronary artery (LMCA) dissection may be similar to that of a patient with atherosclerotic disease of the LMCA. Early diagnosis and urgent coronary artery bypass grafting (CABG) is lifesaving in patients with LMCA dissection. In this retrospective study, we present an account of our management of spontaneous CAD, and we review the medical literature in order to investigate the potential causes and optimal treatments of this condition.

Mayo Clinic SCAD Research Program Presentation A high-point for survivors and those impacted by SCAD was the research presentation which followed at Edward Hospital, Naperville, IL. This year attendees enjoyed meeting and hearing about the latest research findings presented by some of the researchers from the Mayo Clinic SCAD Research Programs (Rochester, MN): Sharonne Hayes, MD: Mayo Clinic SCAD Research Program Team Lead and Chair of our Scientific Advisory Committee Marysia Tweet, MD: Co-creator of Mayo Clinic SCAD Registry, Senior Cardiology/Fellow Jeanne Theis, PhD: Research Scientist in SCAD DNA Research Also attending from Mayo Clinic SCAD Research Program were Jill Boyum (SCAD Research Study Coordinator), Toni Sauber (Medical Secretary) and Brenda Speltz (Clinical Research Coordinator, SCAD Biobank).

Unmanned aerial vehicles, popularly known as drones, are most often associated with airstrikes in modern warfare, but their history goes much further back than that. While drones came into the spotlight during the early years of the 21st century the idea of a remotely-operated flying machine was developed much earlier. A forerunner of what we […]
