Case ReportsLate stent thrombosis secondary to carbon monoxide poisoning.
Carbon monoxide poisoning has a variety of deleterious cardiac effects including arrhythmias, coronary spasm and myocardial infarction. The pro-thrombotic effect of carbon monoxide poisoning is one of the important postulated mechanisms of cardiac injury. ⋯ However, there is no published case of carbon-monoxide-poisoning-induced stent thrombosis. We present a 50-year-old female with late stent thrombosis of a sirolimus-eluting stent secondary to acute carbon monoxide poisoning.

Case ReportsTakotsubo cardiomyopathy in a patient with previously undiagnosed hypertrophic cardiomyopathy with obstruction.
Takotsubo cardiomyopathy (TCM) is usually characterized by left ventricular anteroapical dysfunction in the absence of significant coronary disease commonly precipitated by an emotional or stressful trigger. Hypertrophic cardiomyopathy (HCM) is usually diagnosed on the basis of symptoms, family history, echocardiography, or by the presence of a characteristic murmur. We report a unique case of TCM occurring in a patient with previously undiagnosed HCM with left ventricular outflow tract (LVOT) obstruction who presented with an acute coronary syndrome and ultimately underwent successful alcohol septal ablation. The potential pathophysiologic correlations are discussed.
