Right bundle branch block with revelation of changing axis deviation at the end of atrial fibrillation.
Changing axis deviation has been reported also during atrial fibrillation or atrial flutter. Changing axis deviation has been also reported during acute myocardial infarction associated with atrial fibrillation too or at the end of atrial fibrillation during acute myocardial infarction. Left bundle branch block is usually associated with normal or left axis deviation. ⋯ Changing axis deviation with changing bundle branch block and new-onset of atrial fibrillation during acute myocardial infarction has been also reported. Changing axis deviation with intermittent right bundle branch block in a patient admitted with acute myocardial infarction has been also described. We present a case of a right bundle branch block with revelation of changing axis deviation at the end of atrial fibrillation in a 68-year-old Italian man.

Kounis syndrome is the coincidental occurrence of acute coronary syndromes with allergic or hypersensitivity reactions. Clinicians should be aware that various mediators of allergy can cause coronary spasm and even plaque rupture and thrombus formation, thereby causing a serious impact on the course, prognosis and management of the allergic reaction. We report a case of a 20 year old female who developed acute coronary syndrome after anaphylactic reaction to ibuprofen.

Treatment failure of low molecular weight heparin bridging therapy before a cardiac surgery intervention in a patient with atrial fibrillation.
From time to time, it may be necessary to interrupt oral anticoagulant therapy in preparation for surgical procedures. In high-risk patients or for longer periods, unfractionated or low-molecular-weight heparin bridging treatment has been reported safe. This case focuses attention on treatment failure of low molecular weight heparin bridging therapy in a patient with atrial fibrillation.

Negative pressure pulmonary edema complicating an electrophysiological study.
We report on a case of acute non-cardiogenic negative-pressure pulmonary edema developed during an ablation procedure of an accessory pathway in a patient with no structural heart disease. That potentially serious complication has not been previously reported during an interventional cardiology procedure.

Percutaneous patent foramen closure has emerged as a dynamic therapy for stroke prevention secondary to paradoxical embolism. Recent reports, however, have documented uncertain clinical efficacy and patients with incomplete PFO closure may remain at risk of recurrent events. We sought to identify echocardiographic determinants and the clinical significance of persistent residual shunting after percutaneous PFO closure. ⋯ In patients undergoing percutaneous PFO closure for stroke or TIA, a larger PFO size predisposes to residual shunting approximately 6 months post PFO closure, but with no short term increased risk of recurrent thromboembolic events.
