A Rare Access Site Complication after Transcatheter Aortic Valve Implantation.

In the majority of patients undergoing transcatheter aortic valve implantation, the transfemoral access is the suggested approach due to its less invasive nature and feasibility in patients with suitable vascular anatomy. The complications of the transfemoral access site are generally vascular; however, we herein present a rare case of colon perforation following the transfemoral procedure owing to prior abdominal surgery. A transfemoral aortic valve was inserted on account of severe aortic stenosis and a high probability of surgical mortality.

A Novel Method to Adjust Saphenous Vein Graft Lengths Using 3D Printing Models.

Closure of an acquired aortocoronary venous fistula after coronary artery bypass grafting causing heart failure and stable angina: A case report.

Iatrogenic aortocoronary venous fistula arising from anastomosing an aortocoronary graft to a cardiac vein is a rare a complication following coronary artery bypass grafting. A 75-year-old male patient was admitted with recurrent angina accompanied by congestive heart failure six years after surgery. He was diagnosed with an acquired saphenous vein graft-to- cardiac vein fistula.

Statin treatment in dialysis patients after acute myocardial infarction improves overall mortality.

While statins are widely accepted as a keystone for secondary prevention of cardiovascular disease in the general population, statin treatment in chronic renal failure is still debated. Statins have shown no benefit on cardiovascular outcomes in 4D, AURORA, and SHARP trials conducted in patients on dialysis. However, no study has yet compared statin treatment after acute myocardial infarction in end-stage renal disease (ESRD) patients.

A Cross-Sectional Survey on Reasons for Initial Placement and Replacement of Single Crowns.

Directly ventricular septal defect closure without using arteriovenous wire loop: Our adult case series using transarterial retrograde approach.

Objective: The standard transcatheter ventricular septal defects (VSD) closure procedure is established with arteriovenous (AV) loop and is called as antegrade approach. The directly retrograde transarterial VSD closure without using AV loop might be better option as shortens the procedure time and decreases radiation exposure.

Methods: Our series consist of twelve sequential adult cases with congenital VSDs (seven with perimembranous, four with muscular, one with postoperative residuel VSD).

OPERATOR DEPENDENCY OF THE RADIATION EXPOSURE IN CARDIAC INTERVENTIONS: FEASIBILITY OF ULTRA LOW DOSE LEVELS.

Introduction: Mean radiation exposure in invasive cardiology varies greatly between different centres and interventionists. The International Commission on Radiological Protection and the EURATOM Council stipulate that, despite reference values, 'All medical exposure for radiodiagnostic purposes shall be kept as low as reasonably achievable' (ALARA). The purpose of this study is to establish the effects of the routine application of ALARA principles and to determine operator and procedure impact on radiation exposure in interventional cardiology.

Sixty-five teeth of 30 patients were included in the study, and an Er:YAG laser emitting at a wavelength of 2.94 μm was used for the class I cavity preparations with not more than one third of the mesiodistal width of the occlusal surfaces of each tooth.

Inadvertent implantation of pacemaker lead in the left ventricle: kill two birds with one stone.

We report an asymptomatic patient in whom the intravenous pacemaker (PM) lead was inadvertently implanted in LV through the perforated interventricular septum. He had no embolic events during the last 9 years after the implantation. Possible explanation of the uncomplicated follow-up period is that the patient had been taking warfarin because of mechanical mitral valve prosthesis.

The relationship between platelet indices and clinical features of coronary artery disease.

Background: Platelets play a key role in the development and progression of cardiovascular disease. The degree of platelet activation may be assessed by platelet indices such as platelet count, mean platelet volume (MPV) and platelet distribution width (PDW).

Aim: To evaluate the relationship between platelet indices and clinical features of coronary artery disease (CAD).

In vitro protection of adipose tissue-derived mesenchymal stem cells by erythropoietin.

Mobilization of stem cells and their differentiation into cardiomyocytes are known to have protective effects after myocardial infarction. The integrity of transplanted mesenchymal stem cells for cardiac regeneration is dependent on cell-cell or cell-matrix interaction, which is adversely affected by reactive oxygen species in an ischemic environment. Treatment with erythropoietin was shown to protect human adipose tissue derived mesenchymal stem cells in an ischemic injury in vitro model.

Experimental acute myocardial infarction in rats: HIF-1α, caspase-3, erythropoietin and erythropoietin receptor expression and the cardioprotective effects of two different erythropoietin doses.

The cardioprotective effects of two different doses of erythropoietin administration were analyzed in rats with experimental myocardial infarction.

Infarct sizes measured after triphenyltetrazolium chloride staining, levels of biochemical markers, histopathology examined by light and electron microscopy, and immunohistochemical expressions of erythropoietin, erythropoietin receptor, hypoxia inducible factor-1α and caspase-3, were analyzed.

The relationship between adiponectin, NT-pro-BNP and left ventricular ejection fraction in non-cachectic patients with systolic heart failure: an observational study.

Objective: NT-pro-brain natriuretic peptide (NT-proBNP) has been shown to be an accurate diagnostic marker in patients with heart failure (HF). Adiponectin (Adp) levels are increased in HF but its diagnostic value is still uncertain in these patients. The study was designed to investigate the possible association of these markers in non-cachectic patients with newly diagnosed systolic heart failure.
