Randomized, Controlled Trial with 12-Month Angiographic Follow Up

ABSTRACT: Background. The aim of this study was to compare the use of classic bare- metal stents with dedicated bifurcation bare-metal stents in patients who were not eligible for drug-eluting stents (DES) implantation. Methods. Sixty patients with bifurcation stenosis were randomly assigned to received either a dedicated bifurcation or a  bare-metal stent (n = 30) or classic bare-metal stent (n = 30) with stenting of the parent vessel and angioplasty/or provisional stenting of the side branch. ...

In the Treatment of Rheumatic Mitral Stenosis

 

ABSTRACT: Background. Percutaneous mitral valvuloplasty (PMV) is a well known non-surgical technique for treating patients with rheumatic mitral stenosis (MS). There are very few studies that have compared the 3 techniques together for their safety and efficacy. Methods. To compare the three different techniques for percutaneous mitral valvuloplasty (PMV) using Inoue balloon (IB), metallic commissurotome (PMMC), or multi-track double balloon (MTDB) in patients with MS. Results. A total of ...

ABSTRACT: Objective. To assess the effect of intra-arterial magnesium on the radial artery during transradial cardiac catheterization. Background. Transradial coronary angiography has become popular in the last decade and offers several advantages over transfemoral angiography. Radial artery spasm is a major limitation of this approach, and a vasodilatory cocktail is usually given. The aim of this study was to examine the effect of magnesium sulphate on the radial artery during cardiac catheterization. Methods. This was a prospective, double-blind, randomized trial of 86 patients undergoing...

Impact of Plaque Debulking Prior to Single Sirolimus-Eluting Stent Implantation

ABSTRACT: Background. The impact of plaque debulking with directional coronary atherectomy (DCA) prior to single sirolimus-eluting stent (SES) implantation in an unprotected left main coronary artery (LMCA) involving bifurcation stenosis has not been fully evaluated.  Methods. One hundred and one patients with unprotected LMCA bifurcation lesions treated with single SES implantation (from the LMCA to the left descending coronary artery [LAD] across the left ...

ABSTRACT: We report a case of successful transradial retrieval of a dislodged and mechanically distorted coronary artery stent from the left main stem in an elderly male. Transradial percutaneous coronary intervention was undertaken to reconstruct a lesion in the left circumflex artery complicated by stent dislodgement. A microsnare was used to successfully retrieve the stent.

ABSTRACT: Coronary angiography and intervention can be performed safely using the radial artery. However, arterial spasm is often encountered and usually amenable to nitrate/verapamil therapy. Rarely, surgical intervention is required to remove catheters and wires. Intra-arterial papavarine can be used to treat severe radial artery spasm and prevent the need for urgent surgical intervention.

ABSTRACT: We present the case of a 46-year-old female patient that experienced recurrent stent thrombosis and underwent attempted primary PCI via the radial artery. Although radial artery cannulation with a 6 Fr sheath and the diagnostic angiography were successfully performed, the PCI could not be achieved because of failure to advance the 6 Fr guide through the radial artery, due to severe angulation of a high take-off radial artery, combined with a proximal radial artery stenosis.
