Takotsubo Cardiomyopathy Associated with Guillain-Barré Syndrome: a Differential Diagnosis from Dysautonomia Not to Be Missed
A 60-year-old woman presented with a 1-week progressive limb weakness and an areflexic tetraparesis. Both neurophysiological and cerebrospinal fluid examinations were consistent with diagnosis of Guillain-Barré syndrome (GBS) and a treatment by intravenous immunoglobulin over a 5-day period was started. At the end of the treatment, the patient suffered from an acute coronary syndrome (ACS) without stenosis at coronary arteriography. Left ventriculography showed segmental wall motion abnormalities with apical akinesis contrasting with hyperkinesis in basal segments, with a depressed left ventricular ejection fraction at 45%. Cardiac magnetic resonance imaging excluded the diagnosis of myocarditis. A diagnosis of "transient left ventricular apical ballooning syndrome" or "Takotsubo" syndrome was then made and a treatment by angiotensin-converting enzyme inhibitor and beta-blocker was introduced. Left ventricular dysfunction and electrocardiogram normalized within two weeks and the patient remained free from cardiovascular events at one year of follow-up. This cardiomyopathy is a recently known and now commonly diagnosed reversible systolic dysfunction mimicking ACS and is secondary to physical or emotional stress affecting mainly post-menopausal women. Electrocardiographic and echocardiographic abnormalities are often regressive in days or weeks, and rarely responsible for complications. This observation supports clinical evidence that electrocardiographic changes in GBS can be linked to Takotsubo syndrome, by means of the stressful trigger of GBS occurrence. This reversible cardiomyopathy needs adequate management and specific therapeutic strategies. Therefore, trans-thoracic echocardiography should be systematically performed when repolarisation abnormalities are present in this disease to rule out a Takotsubo syndrome, even in asymptomatic patients.
[Frequency and Type of Gifts Given by Pharmaceutical Industry to Cardiology Residents]
Cardiovascular diseases are the leading cause of death in the world and cardiologists are an important target for the pharmaceutical industry. We evaluated cardiology residents' exposure to pharmaceutical companies.
Coronary Angiography of Pregnancy-associated Coronary Artery Dissection: a High-risk Procedure
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome occurring predominantly in young women without any cardiovascular risk factors, especially during the peripartum and early postpartum period. Here, we report a case of a 28-year-old pregnant woman who was found to have an isolated distal SCAD of the left anterior descending artery (LAD). Coronary angiography was complicated by extensive LAD and circumflex arteries dissection, requiring an emergency coronary artery bypass grafting associated with ventricular assist device implantation and underlying the extreme fragility of coronary arteries in pregnant women.
Incidental Extracardiac Findings in Cardiac Computed Tomography Performed Before Radiofrequency Ablation of Atrial Fibrillation
Radiofrequency ablation has became a validated therapeutic technique for symptomatic drug refractory atrial fibrillation (AF). Cardiac computed tomography (CT) is used to evaluate left atrial (LA) anatomy in order to improve AF ablation. The analysis of noncardiac structures during cardiac CT may identify clinically significant incidental findings (IFs). The objective of this study was to determine the prevalence of IF in patients undergoing AF catheter ablation.
Acquired Left Ventricular Submitral Aneurysms in the Course of Takayasu Arteritis in a Child
A 9-year-old black African boy was hospitalized for heart failure revealing a severe left ventricular dysfunction associated with dilated cardiomyopathy, two submitral aneurysms, occlusion of the circumflex artery and a giant coronary artery aneurysm on the proximal left anterior descending artery. The boy was coinfected with human immunodeficiency virus and Mycobacterium tuberculosis. Though rare, association of Takayasu arteritis and submitral aneurysm leads to rethinking the pathogenesis of submitral aneurysm and suggests that some of them may be acquired. In our case, a common inflammatory process, possibly triggered by tuberculosis or HIV, may underlie Takayasu and submitral aneurysms.
