A rare complication following radiofrequency ablation.

Atrial-oesophageal fistula (AOF) formation is a rare but often fatal complication post radio frequency ablation (RFA). Mortality ranges from 67% to 100%, with a rapid progression from symptom onset to death. We report a case of a healthy man in his early 40s who presented with a Glasgow Coma Scale  of 5/15, clinical evidence of sepsis and Streptococcus viridans bacteraemia, 14 days following uncomplicated RFA for atrial fibrillation.

Diagnostic dilemmas in cardiology.

A 29-year-old pregnant woman presented in accident and emergency with severe acute left ventricular failure requiring admission to the intensive care unit. A nasal swab was found to be positive for H1N1 making peripartum and viral cardiomyopathies, the most likely differential diagnoses. CT coronary angiography and subsequent invasive angiography revealed an anomalous coronary system thus making ischaemic cardiomyopathy also a possibility.

Decreasing operators' radiation exposure during coronary procedures: the transradial radiation protection board.

Aim: Transradial coronary procedures are associated with decreased vascular access site complications and other benefits compared to the femoral approach. There is some concern however about high-recorded radiation doses for interventional cardiologists using the transradial route. We therefore designed and investigated the effect of a transradial radiation protection board (TRPB) on operator radiation exposure during coronary procedures.
