Technical difficulties during electronic cardiac device implantation in patients with persistent left superior vena cava.

We report a case of persistent left superior vena cava (PLSVC), discovered by chance during the cardiac electronic device placement procedure. PLSVCs are congenital anomalies of the thoracic vasculature, during which remnants of the left superior vena cava drain into the right atrium through the coronary sinus. PLSVCs can vary in their location and overall anatomy.

Iatrogenic tracheal rupture after extubation in the context of acute decompensated heart failure and cardiac device implantation: a case report.

Iatrogenic tracheal rupture is a life-threatening airway complication. It has a very low reported incidence and is more prevalent in women and patients over 50 years of age. The most frequent clinical manifestations of tracheal injury are subcutaneous emphysema and respiratory distress.

Bochdalek Hernia As A Cause Of Intermittent AV Block.

Congenital diaphragmatic hernia is very rare cause of AV block. We report such a patient with sick sinus node syndrome and previous AAIR pacemaker implantation, in which intermittent AV block was diagnosed by 24-hours ECG monitoring and upgrade of pacing system to DDDR was suggested.

Duration of the A(H)-A(Md) interval predicts occurrence of AV-block after radiofrequency ablation of the slow pathway.

Purpose: Modification of the slow pathway (SP) of the atrio-ventricular node by radiofrequency ablation is the most effective treatment to cure AV nodal reentry tachycardia (AVNRT). However, this therapy may be complicated by AV-block (AVB). We sought to evaluate the predictive value of the A(H)-A(Md) interval-the electrical delay between atrial signals on the His- and the ablation-catheter-upon development of AVB during SP ablation.

Long-term results of high vs. normal impedance ventricular leads on actual (Real-Life) pacemaker generator longevity.

Aim: The long-term effects of high impedance vs. standard impedance pacing leads on actual generator longevity were studied.

Methods And Results: In 40 patients (21 females, age 73 +/- 13 years) with standard dual-chamber pacemaker indication, bipolar standard impedance ventricular leads and high-impedance leads were implanted in a randomized fashion.
