A 55-year-old diabetic woman suffered a posterior wall ST-elevation myocardial infarction. She developed contrast-induced nephropathy following coronary angiography. Acute fulminant uremic neuropathy was precipitated which initially mimicked Guillan-Barre Syndrome, hence reported.

Longitudinal stent deformation (LSD) is a rare complication but can occur during coronary intervention. We report a case with LSD of the distal edge, documented by an optical coherence tomography investigation and successfully recovered.

Chronic Chagas cardiomyopathy (CCC) is a late complication of Chagas disease with various manifestations including arrhythmia, heart failure, thromboembolism, and stroke. In a patient with symptoms of heart failure and left ventricular apical aneurysm unexplained by structural heart or coronary vascular abnormalities, CCC should be strongly considered and inquiry made about exposure status. Typical electrocardiographic findings of bundle branch block, complete heart blocks, and ventricular arrhythmia are helpful clues...

Although provisional pacemaker implantation can safely be done in many cases, a rare complication such as knotted electrode has been described, especially when the procedure is performed without fluoroscopy guidance. We describe a case of knot creation in a provisional pacemaker which was successfully retrieved using a snare after cutting the electrode proximally.

Guidewire-induced pseudo-lesions are referred to accordion phenomenon and are infrequent occurrences during percutaneous coronary intervention of tortuous coronary arteries. Their occurrence can be a diagnostic challenge to the interventionist and might lead to unnecessary intervention. Ischemia and hemodynamic compromise are possible complications, if not managed promptly. The differential diagnosis includes coronary dissection, thrombus, and spasm. We describe a patient who developed pseudo-lesions of the tortuous right coronary artery in multiple segments during PCI...

OBJECTIVES: The objective of this study is to describe contemporary management and 1-year outcomes of patients hospitalized with ST-segment elevation myocardial infarction (STEMI) in Arabian Gulf countries. METHODS: Data of patients admitted to 29 hospitals in four Gulf countries [Bahrain, Kuwait, Oman, United Arab Emirates (UAE)] with the diagnosis of STEMI were analyzed from Gulf locals with acute coronary syndrome (ACS) events (Gulf COAST) registry. This was a longitudinal, observational registry of consecutive citizens, admitted with ACS from January 2012 to January 2013...

Calcific pericarditis (CP) is a rare disease which results from long-standing pericardial inflammation. Pericardial calcification may completely or partially encase the ventricles, resulting in impaired diastolic filling. We present a case of a 53-year-old male who was incidentally found to have annular CP resulting in external compression of a large territory diagonal branch (D1) reaching the apex with likely chronically occluded left anterior descending artery with collateral circulation from the right coronary artery with hemodynamic compromise on coronary angiography...

Williams-Beuren syndrome is a multisystem genetic disorder caused by hemizygous deletion on chromosome 7q11.23, encompassing about 28 genes including the elastin gene, ELN. Cardiovascular abnormalities are frequent and are related to elastin insufficiency. These abnormalities include supravalvular aortic stenosis (SVAS) in 70% of case, pulmonic valve stenosis, and renal artery stenosis. Definitive therapy for supravalvar aortic stenosis consists of surgical correction of the arteriopathies. Outcomes after surgical correction of SVAS depend on the extent of the arteriopathy and the presence of other associated lesions...

Myocardial clefts are rare incidental findings without clinical relevance up to now. The recognition of this imaging entity is of crucial importance to avoid misdiagnosis and even more in the context of coronary artery disease.

The case of a 24-year-old male with complaints of migraine headaches was referred for echocardiography. The rest of medical history was unremarkable. Agitated saline contrast bubble study showed evidence of a right to left intracardiac shunt, probably secondary to a patent foramen ovale. Results of a transesophageal echocardiogram suggested the possibility of an anomalous venous circulation and eventually identified as anomalous left-sided superior vena cava with cardiac magnetic resonance imaging.
