Removal of an active fixation coronary sinus pacing lead 5 years postimplant: A case report.

Active fixation for a lead in the coronary sinus may be essential to select the optimal left ventricular pacing site, maximize the effectiveness of cardiac resynchronization therapy (CRT) and avoid dislodgement. The Medtronic Attain Stability lead allows fixation through a side helix concentric with the lead body. Although electrical performance of such a lead is well known, evidence of extractability remains poor especially in the long term.

Remote assessment of QT interval: A new perspective for implantable cardiac monitors.

Background: There is an unmet need for simple tools for monitoring QT intervals. The feasibility of measuring the QT interval on the single‑lead subcutaneous electrocardiogram (subECG) recorded and transmitted by implantable cardiac monitors (ICMs) has never been tested.

Methods: We performed a standard ECG in patients who had already been implanted with a long sensing vector ICM (BIOMONITOR, Biotronik SE&Co.

Reverse takotsubo cardiomyopathy followed by left ventricle outflow tract obstruction: A dangerous relay race.

Reverse takotsubo cardiomyopathy (rTTC) is a less frequent variant of takotsubo cardiomyopathy (TTC) with several differences about epidemiology and clinical aspects. While left ventricular outflow tract (LVOT) obstruction is relatively frequent in TTC patients, this complication has not been reported in the setting of rTTC yet. We describe the case of a female patient with rTTC complicated by LVOT obstruction and systolic anterior motion of mitral valve: the onset of these findings coincided with the regression of wall motion abnormalities.

Changes in oral anticoagulation for elective cardioversion: results from a European cardioversion registry.

Aims: In patients with atrial fibrillation (AF) pharmacological or electrical cardioversion may be performed to restore sinus rhythm. The procedure is associated with an increased risk of thromboembolic events, which can be significantly reduced by adequate anticoagulation (OAC). Our aim was to create a partly prospective, partly retrospective cardioversion registry, particularly focusing on OAC strategies in different European countries, and on emerging choice of OAC over time.
