The effects of carotid artery stenting on short-term clinical outcomes and evaluation of restenosis

Objectives: Data on restenosis and long-term outcomes of carotid stenting are limited. The aim of this study was to investigate cardiovascular effects of carotid stenting on clinical outcome and restenosis in patients with symptomatic severe carotid artery stenosis.Materials and methods: Twenty patients (mean age: 68±7 years, 11 male) who have been decided to perform stenting in joint Committee of Cardiology, Cardiovascular Surgery and Neurology Clinics were included.Patients were evaluated both clinically and Doppler ultrasonographically for frequency of cardiovascular events and restenosis. Restenosis is defined as the reapperance of stenosis with a diameter reduction of ≥%50 with peak systolic velocity higher than 224 cm/s.Results: Comorbidities in patients were; coronary artery disease in 14, peripheral artery disease in three, and both chronic renal failure and congestive heart failure in two. Stent diameters were ranged from 6 to 8 mm, and stent lengths were 30 and 40 mm. During the procedure 5 patients had predilatation and 19 had postdilatation. None of the patients had >%30 resudial stenosis after the procedure. All procedures were technically successful. After the procedure only one transient ischemic attack was seen. There were no restenosis, myocardial infarction, death or stroke at 30th day end of the first year of follow up. Diabetes and heart failure were found as predictors for restenosis.Conclusion: In highly selected cases, carotid artery stenting is an effective and safe method in the short term. Restenosis did not seem to be a restricting problem for the success of carotid artery stentin

Obstruction of superior vena cava flow during transcatheter atrial septal defect closure with the Atriasept ASD occluder

In this paper, we describe a patient with a large secundum atrial septal defect ASD (26 mm) with adequate rims that were suitable for percutaneous closure. While closing this ASD, the superior vena cava (SVC) was occluded with the right atrial disc of the Atriasept ASD occluder (Cardia) and thus the device was retrieved before its release. After retrieval of this device, an Amplatzer ASD occluder was successfully implanted without disturbing the caval flow

Hemodynamic deterioration and ST-segment elevation developed in a patient during transcatheter aortic valve implantation

Transcatheter aortic valve implantation is becoming increasingly popular as an alternative treatment technique for symptomatic patients with severe aortic stenosis, who are at high risk for surgery. However, with this revolutionary treatment modality, some fatal complications have also emerged. One of these fatal complications is the occlusion of the left main coronary artery at the time of procedure. In this case report, we presented a case of a transcatheter aortic valve implantation complicated by acute left main trunk subtotal oc-clusion and hemodynamic collapse, which was successfully resolved by balloon angioplasty and stent implantation

Percutaneous closure of perimembranous ventricular septal defects associated with septal aneurysm in adults.

Objective: Percutaneous closure of perimembranous ventricular septal defects (pmVSD) has become an accepted alternative to surgical closure in selected cases. However, closure of pmVSDs associated with septal aneurysm is more challenging. We report our experience of device closure of pmVSDs associated with septal aneurysm

Transjugular closure of secundum atrial septal defect in a patient with interrupted inferior vena cava

In this case, we report a successful closure of secundum atrial septal defect in a 32-year-old female patient with an interrupted inferior vena cava (IVC). Interrupted IVC was detected coincidentally during right heart catheterization. The defect was successfully closed through transjugular vein approach as an alternative to surgery

The validity and reliability of the Turkish version of the University of Toronto Atrial Fibrillation Severity Scale.

Background/aim: There are various instruments to assess quality of life (QoL) in patients with atrial fibrillation (AF). The aim of this study is to determine the reliability and validity of the Turkish version of the University of Toronto Atrial Fibrillation Severity Scale (AFSS)

Nontraumatic muscular hematoma of lower extremity in a patient using warfarin and its relationship with VKORC1, CYP2C9 gene polymorphism

Warfarin is the most frequently used oral anticoagulant agent today. Warfarin response can be affected by environmental factors such as dietary habits and drugs as well as genetic factors, and this might increase bleeding risk. In this article, we report a 79-year-old male patient who developed nontraumatic hematoma of left lower extremity despite using low-dose warfarin, and whose genetic analyses revealed CYP2C9*2*3, VKORC1 AA and VKORC1 TT gene polymorphisms
