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 presence of a sidebranch (> 1 mm) at the site of the lesion. The authors included 151 patients with 185 sidebranches in this report originating at the level of the lesion. Eighty-eight patients (110 sidebranches) underwent direct stenting, while 63 patients (75 sidebranches) underwent stenting with balloon predilatation (conventional stenting). The

Balloon mitral commissurotomy (BMC) using the Inoue balloon catheter is now an established mode of therapy for suitable cases of mitral stenosis with results comparable to closed as well as open surgical commissurotomy.1–3 With growing experience, increasingly complex cases are being effectively treated with this method using, at times, modifications in technique.4–7
Case Report. A 35-year-old woman (height, 164 cm; weight, 48 kg) with symptomatic severe mitral stenosis was evaluated for undergoing BMC. Echocardiography revealed non-calcific mitral stenosis (valve area, 0.8

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-stent restenosis is also high (> 30%), regardless of treatment modalities, including balloon angioplasty,3–5 rotational atherectomy,6,7 and repeat stenting. The effectiveness of stent therapy can be questioned, particularly in patients with recurrent restenosis after stent implantation. If the factors for recurrent restenosis can be predicted a

Multiple in vitro and in vivo studies have suggested that interactions involving thrombosis, coagulation proteins, and the arterial wall may be important in neointimal tissue growth and restenosis.1 It has also been shown that vascular smooth muscle cell proliferation plays a major role in the genesis of restenosis after angioplasty or vascular injury. In addition to its anticoagulant effects, heparin has been widely reported to inhibit smooth muscle cell proliferation and migration, which is widely recognized as the most important mechanism of restenosis.2,3 In vitro experiments using cell cu

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 for implantation of arrhythmia control devices in patients with PLSVC.9 In many such cases (about 10–17%), the right superior vena cava is also absent.5 A few reports have described different approaches in different clinical situations.6–8 To our knowledge, this is the first case report of implantation of dual-chamber pace maker via PLSVC utili

Although once considered to be a contraindication, accumulating data regarding stenting in thrombogenic milieu [acute myocardial infarction (AMI), unstable angina pectoris] in the presence of angiographically apparent thrombus reveal promising results with very low acute and subacute thrombosis rates.1–4 Obtaining TIMI 3 flow with percutaneous coronary intervention (PCI) was associated with a better prognosis in AMI.5 The GUSTO trial demonstrated a worse clinical outcome in cases where TIMI 3 flow could not be obtained.6
Primary angioplasty and thrombolytic therapy are the major treatment

Angioplasty and stenting are becoming increasingly accepted techniques for the treatment of carotid stenosis. Compared to endarterectomy, carotid stenting is a less invasive procedure that provides an attractive treatment alternative for some patients, particularly those with severe cardiac co-morbidities. The feasibility and safety of the carotid stenting procedure as a treatment for severe carotid stenosis has improved with recent technological advances. However, the optimal stent for carotid revascularization is unknown. The objective of this study was to assess immediate angiographic resul
