Clinical TrialNavigation by parallax in three-dimensional space during fluoroscopy: application in guide wire-directed axillary/subclavian vein puncture.
Fluoroscopy is range ambiguous--the relative positions in three-dimensional space of two structures with superimposed silhouettes cannot be ascertained. The parallax effect can be used to overcome this problem, and was used to develop a technique of axillary/subclavian vein puncture. ⋯ The new technique was effective, efficient, and safe when implemented in clinical practice, justifying the parallax principles on which it is based. The parallax principles may be applied to other invasive medical procedures with due modifications.

Case ReportsDexmedetomidine related cardiac arrest in a patient with permanent pacemaker; a cautionary tale.
Dexmedetomidine (Precedex), an alpha-2 adrenergic receptor agonist is frequently and safely used as sedative agent during surgical procedures. We report a case of a 76-year-old woman who developed cardiac arrest from the use of dexmedetomidine during pacemaker lead extraction procedure.

Clinical TrialAn approach to ablate and pace:AV junction ablation and pacemaker implantation performed concurrently from the same venous access site.
Atrioventricular junction (AVJ) ablation combined with permanent pacemaker implantation (the "ablate and pace" approach) remains an acceptable alternative treatment strategy for symptomatic, drug-refractory atrial fibrillation (AF) with rapid ventricular response. This case series describes the feasibility and safety of catheter ablation of the AVJ via a superior vena caval approach performed during concurrent dual-chamber pacemaker implantation. ⋯ Catheter ablation of the AVJ can be performed successfully and safely via a superior vena caval approach in patients undergoing concurrent dual-chamber pacemaker implantation.
