Multislice CT for assessing in-stent dimensions after left main coronary artery stenting: a comparison with three dimensional intravascular ultrasound.

Objective: To evaluate the agreement between multislice CT (MSCT) and intravascular ultrasound (IVUS) to assess the in-stent lumen diameters and lumen areas of left main coronary artery (LMCA) stents.

Design: Prospective, observational single centre study.

Setting: A single tertiary referral centre.

Long-term follow-up after percutaneous treatment of the unprotected left main stenosis in high risk patients not suitable for bypass surgery.

Introduction And Objectives: Percutaneous coronary intervention is recommended in patients with unprotected left main stenosis non suitable for coronary artery bypass graft. Long-term follow-up of those patients remains uncertain.

Methods: All patients with de novo unprotected left main stenosis treated with stent implantation were consecutively enrolled.

Atrial asystole during ventricular pacing following radiofrequency catheter ablation of accessory pathways.

Sinus node bradycardia or sinus node arrest is a documented phenomenon during radiofrequency catheter ablation. In addition, sinus node inhibition during ventricular pacing has been described as an infrequent occurrence in the course of diagnostic electrophysiology studies. The proposed mechanism in both situations is intense stimulation of vagal afferent pathways leading to a Bezold-Jarisch-like phenomenon.

Use of Impella Recover LP 2.5 in elective high risk percutaneous coronary intervention.

We describe a single-center experience in using the Impella Recover LP 2.5 in the setting of high-risk elective percutaneous coronary interventions. This device is placed percutaneously to support cardiac output and has a better profile than other left ventricular assist devices.
