Using a steerable stylet, we were able to direct the tip of the lead toward the tricuspid valve and implant it at the right ventricle.
Implantation of a Dual-Chamber Pacemaker in a Patient with Persistent Left Superior Vena Cava Using a Steerable Stylet
A persistent left superior vena cava (PLSVC) is a rare abnormality that presents a challenge to the implanter. Its incidence varies from 0.3–0.5% of the population.1,2 It has always been recommended that the right superior vena cava (RSVC) be used fo…
Predictors of Recurrent Restenosis After Coronary Stenting: An Analysis of 197 Patients
In recent years, coronary stent placement has become an established treatment for patients with coronary artery disease.1,2 However, in-stent restenosis has been reported to occur in 20–30% of patients, and the restenosis rate after treatment for in-…
Sidebranch Patency During Main Branch Stenting: Try to Keep the Branch Open Immediate and Long-Term!
The study presented by Timurkaynak et al. in this issue of the Journal discusses a contemporary topic, which is direct stenting.1 It is interesting that the evaluation of this technique is performed in the setting of coronary bifurcations or in the p…

Transradial Three-Vessel Coronary Angioplasty in a Patient with Bilateral Radial Artery Stenoses
The transradial approach as an access for percutaneous coronary intervention (PCI) has been widely adopted. However, anatomical variations and stenoses may pose significant challenges to the operator. We report a case of successful transradial PCI in…

Is Carotid Stenting of Complicated Plaques Safe?
Introduction The risk of embolization during CAS may be influenced by a number of factors. Many studies have focused on the risk associated with catheterization maneuvers, experience of the physician, techniques and types of device used.1 Plaque char…

Similar Case of Anomalous Origin I read the article regarding a single coronary artery by Namboodiri et al,1 published in the April 2007 issue of the Journal of Invasive Cardiology, with great interest. However, the authors missed referencing a few i…
Spontaneous Coronary Artery Perforation Secondary to aSirolimus-Eluting Stent Infection
Coronary stent implantation is one of the most common medical procedures, with nearly 1 million patients in the United States undergoing this intervention annually.1 The incidence of stent infection is unknown, but appears to be quite rare, given the…
Sidebranch Compromise During Percutaneous Coronary Interventions
Sidebranches are within the vicinity of the angioplasty site in over 50% of cases and although many are unaffected, a considerable proportion are compromised by the procedure. In this article, we systematically review the current literature concernin…
