We present a case of a 52 year old female who suffered from a sudden syncope. A coronariography was performed and spontaneous coronary dissection was diagnosed in the posterior descending artery after an optical coherence tomography (OCT) was performed. A conservative management was decided. During hospitalization the patient presented with an episode of chest pain with an anterior ST elevation on ECG. Coronariography showed total occlusion of the left descending artery and again a dissection was diagnosed by OCT. This time, 2 stents were implanted in the affected artery. The hypothesis that the coronary adventitial volume of vasa vasorum is higher in patients with spontaneous coronary artery dissection has been demonstrated in a recent small study and it was observed in this patient. Conservative management is preferred in most cases, proceeding to revascularization for patients with ongoing chest pain, hemodynamic instability and ST elevation, mostly if it affects major arteries.

The Tako-tsubo syndrome (TS) is a reversible acute cardiomyopathy simulating an infarction. We analyzed 60 patients admitted with TS in our center.A percentage of 73.3 were women (mean age: 70.6 ± 11.8 years); 83.3% had some cardiovascular risk factor, 25% had an anxiety-depressive disorder and in 58.3% a precipitating factor was identified, emotional stress being the most frequent. A percentage of 15.3 showed complete left bundle branch block (LBBB). In 23.3% of patients, contractile abnormalities respected the apex (mid ventricular or diaphragmatic types).The anterior descending artery showed no significant lesions in 35% of patients and in 68.3% it had a diaphragmatic segment. Forty percent of patients developed heart failure (HF) and 18.3% cardiogenic shock (CS). The overall in-hospital mortality was 3.3%, while it was 8.3% among those patients who developed HF. The incidence of CS was higher among patients with LBBB (44.4 vs. 13.7%, P=.05) and males (43.8 vs. 9.1%, P=.005).Although in-hospital mortality in patients admitted due to TS is low, a significant percentage of these patients develop HF with a high mortality in this subgroup. Males and patients with LBBB had higher in-hospital morbidity.
