[Acute coronary syndrome without ST segment elevation in a 78 year-old woman caused by critical proximal right coronary artery stenosis with concomitant chronic total occlusion of left main coronary artery].

Total occlusion of the left main coronary artery is a rare finding at coronary angiography. When present, patients most often have extensive collateral circulation from the right coronary artery. The mainstay of treatment is surgical with coronary artery bypass grafting.

[Simultaneous subacute thrombosis in bare metal stents implanted into right coronary artery and left anterior descending artery without coexistence of resistance to antiplatelet therapy].

In-stent thrombosis is a rare but devastating complication of coronary stent implantation, occurring in 0.5% to 1.9% of patients with bare metal stents (BMS).

[Tako-tsubo syndrome - a form of acute coronary syndrome or completely different clinical entity - a case report].

Tako-tsubo cardiomyopathy, also known as stress-induced cardiomyopathy, is a temporary left ventricular dysfunction characterised by acute retrosternal rest pain, ST - segment elevation, slight elevation of cardiac necrosis markers, preferential apical akinesia or hypokinesia with basal hypercontractility in echocardiography. Its clinical picture mimics an acute coronary syndrome. Coronary angiography reveals normal coronary arteries.
