ABSTRACT
34-year-old male with history of recurrent atrial fibrillation (AF) and mitral stenosis, status post radiofrequency ablation (RFA) and prosthetic mitral valve replacement two years earlier was admitted with prosthetic valve thrombosis for redo mitral valve surgery. During the surgery, a 2 x 1.5 x 1 cm mass was identified on the interatrial septum, attached to the edge of tricuspid valve's septal leaflet by a stalk. The mass was excised and histological evaluation revealed myxoma. It is accepted that myxomas can develop after cardiac trauma. It is known that RFA for AF increases the risk of thrombus or endocarditis in the atrium. Herein, we report a myxoma case where we think the heat energy caused by RFA might have triggered the development of the tumor.

An 82-year-old hypertensive, diabetic woman was admitted to our department for pre-operative cardiac evaluation. A myocardial perfusion scan revealed apicoseptal and inferior segment hypoperfusion. Coronary angiography exhibited extensive multiple coronary cameral fistulae draining into the left ventricle in a homogeneous and circular way.

We report on a 37-year-old patient who suffered from myocardial stunning after exposure to carbon monoxide, despite having normal coronary arteries. As myocardial ischaemia may be asymptomatic in these patients, close monitoring with serial electrocardiography and of serum cardiac enzymes and troponins is recommended.

A 74-year-old man presented with chest pain and dyspnoea at the cardiology outpatient clinic. His past medical history included an anterior myocardial infarction in 2008. In the coronary angiogram, a 'halo image' was seen right after the injection of the contrast agent, and it corresponded with the location of the left ventricular aneurysm. A calcified left ventricular aneurysm with mural thrombus was confirmed with cardiac MRI and a CT scan.
