Case ReportsA rare case of a cardiac papillary fibroelastoma of the pulmonary valve diagnosed by echocardiography.
Primary cardiac tumors are rare. The majority of primary tumors of the heart are benign with papillary fibroelastomas being the third most common after myxomas and lipomas respectively. ⋯ The majority of fibroelastomas have been described on the left side of the heart involving the aortic and mitral valves. We present a rare case of a papillary fibroelastoma occurring on the pulmonic valve.

Case ReportsImminent pulmonary embolism: a fatal mobile right atrial thrombus.
Right sided heart thrombi are infrequent and if they are mobile they may cause serious morbidity and mortality due to massive pulmonary embolism or paradoxical embolism. Malignancies are one of the important etiological factors for right heart thrombi. ⋯ Urgent open heart surgery was decided but imminent massive pulmonary embolism complicated the case leading to irreversible cardiogenic shock. By means of the presented case this paper overviews etiological factors and treatment options for right sided heart thrombi.

Case ReportsSingle coronary artery presenting with cardiogenic shock due to acute myocardial infarction.
Percutaneous coronary revascularization plays an important role in the management of acute coronary syndrome. Unpredictable angiographic findings of anomalous coronary arteries may, however, compromise the otherwise high and predictable success rates of this intervention. We report a case of failed coronary angioplasty of the left anterior descending artery through an anomalous left main coronary artery originating from the right coronary sinus in a 33-year-old man with acute myocardial infarction complicated by cardiogenic shock. Subsequently the patient performed successful emergency coronary artery bypass graft.

Case ReportsMRI demonstration of acute myocardial infarction due to posttraumatic coronary artery dissection.
A case of left ventricular lateral wall myocardial infarction in the distribution of circumflex coronary artery (LCX) was demonstrated by magnetic resonance imaging in a 55-year-old woman. Dissection of the proximal LCX due to blunt chest trauma was followed by percutaneous coronary artery stenting. MR (magnetic resonance) imaging of myocardial infarction is reviewed.

Multicenter StudyIntercentre reproducibility of magnetic resonance T2* measurements of myocardial iron in thalassaemia.
In transfusion-dependent thalassemia major, iron-induced cardiomyopathy is the predominant cause of morbidity and mortality. Assessment of myocardial iron loading using MRI gradient echo T2* measurements have been described, but has only been performed at one centre in London. We assessed the transferability of this method by comparing the results from three different MR scanners in three different countries. ⋯ The mean difference and coefficient of variability for the heart between scanners was 0.08 ms and 9.7% between London and Athens; and 0.30 ms and 1.6% between London and Cagliari. The interstudy mean difference and coefficient of variability for the heart in Athens was 0.6 ms and 3.5%, and 0.2 ms and 2.4% in Cagliari. In conclusion, the myocardial iron estimations were consistent between the three centres with scanners of differing manufacture, suggesting that this technique may have widespread application in the assessment of patients with iron overload conditions such as thalassaemia.
