Predictive Value of Thromboembolic Risk Scores Before an Atrial Fibrillation Ablation Procedure

Risk Scores for Atrial Fibrillation Ablation Introduction: It is not clear whether transesophageal echocardiography (TEE) should be performed prior to a planned atrial fibrillation (AF) ablation in all patients.

Vasovagal syncope initiating ventricular fibrillation in a healthy subject.

A 62-year-old man with cured lymphoma as only significant medical history experienced a first reflex syncope after prolonged orthostatic posture, with cardiac arrest. Prolonged asystole was followed by ventricular fibrillation needing external defibrillation. The defibrillator provided complete recordings. Thorough investigation revealed no cardiac abnormalities apart from a few right ventricular outflow tract premature complexes. This patient benefitted from implantation of an ICD for ventricular fibrillation secondary to reflex syncope, usually considered benign.

Variable morphologies of preexcitation due to a concomitant Brugada pattern

Since the first publication of the Brugada syndrome in 1992 several variants of this ECG pattern have been described. We report a very unusual case of preexcitation with changing electrocardiographic morphologies which appeared to be an association of a variable Brugada pattern with a persistent antegrade preexcitation.

Integrity of the Ganglionated Plexi is Essential to Parasympathetic Innervation of the Atrioventricular Node by the Right Vagus Nervez

Radiofrequency isolation of pulmonary vein can be accompanied by transient sinus bradycardia or atrioventricular nodal (AVN) block, suggesting an influence on vagal cardiac innervation. However, the importance of the atrial fat pads in relation with the vagal innervation of AVN in humans remains largely unknown. The aim of this study was to evaluate the role of ganglionated plexi (GP) in the innervation of the AVN by the right vagus nerve.

Late diagnosis of a congenitally corrected transposition of the great arteries discovered at pacemaker implantation in a patient previously diagnosed with dextrocardia and situs solitus

Congenitally corrected transposition of the great arteries (CCTGA) should not be missed in patients with dextrocardia and situs solitus. We report a case of a 56‐year‐old man with late diagnosis of CCTGA after ventricular lead replacement. Free LV wall pacing may be favorable in these patients so to prevent deterioration of the systemic RV function.
