TNM and Modified Dukes staging along with the demographic characteristics of patients with colorectal carcinoma.

Aim: Colon adenocarcinoma, is the most common cancer in gastrointesinal system (GIS). The whole world is an important cause of morbidity and mortality. TNM and modified Dukes classification which has great importance in the diagnosis and treatment of Colorectal cancer (CRC).

Significance of aortic valve calcification in patients with low-gradient low-flow aortic stenosis.

Background: Assessment of patients with aortic stenosis (AS) and impaired left ventricular function remains challenging. Aortic valve calcium (AVC) scoring with computed tomography (CT) and fluoroscopy has been proposed as means of diagnosing and predicting outcomes in patients with severe AS.

Hypothesis: Severity of aortic valve calcification correlates with the diagnosis of true severe AS and outcomes in patients with low-gradient low-flow AS.

Predictive value of renal resistive index in percutaneous renal interventions for atherosclerotic renal artery stenosis.

Background: The clinical benefit of percutaneous interventional therapies for atherosclerotic renal artery stenosis (ARAS) is still obscure. Randomized trials conducted on general patient populations provided unsatisfactory results in justifying the interventional treatment. In this study, the predictive value of renal resistive index (RRI) was retrospectively analyzed in identifying the patients who may benefit from renal angioplasty and stenting.

Outcomes of carotid stenting in patients with previous neck radiation.

Objectives: Our aim was to report outcomes of percutaneous stenting of carotid stenosis in patients with previous neck radiation.

Background: Post-irradiation carotid disease is often extensive and involves atypical areas. Data regarding outcomes of stenting of these lesions are scarce.

Percutaneous coronary revascularization in coronary artery disease: lessons from a single center experience.

Objectives: To determine the role of percutaneous coronary intervention (PCI) and its impact on mortality in coronary artery disease (CAD).

Background: It's unclear whether PCI provides benefit in patients with CAD outside of acute settings. We sought to determine the role of PCI and its effect on mortality in patients with similar entry criteria to prior RCTs and compare outcomes with medical treatment.

Do bisphosphonates slow the progression of aortic stenosis?

Objectives: The aim of this study was to investigate the impact of bisphosphonates on the progression of aortic stenosis.

Background: Valvular calcification is associated with the development and progression of aortic stenosis. Bisphosphonates have been suggested to slow this progression.

Technique and outcome of ostial common carotid artery stenting: a single centre experience.

Aims: Our aim was to report techniques and outcomes of our experience in percutaneous stenting of ostial common carotid artery lesions.

Methods And Results: We retrospectively reviewed patient medical records at our institution from January 2005 until April 2011 to determine baseline characteristics, procedural details and follow-up data of patients who underwent percutaneous stenting of ostial lesions of the common carotid artery. Our study included 17 patients of whom eight (47%) were male.

Prognostic implications of pulmonary hypertension in patients with severe aortic stenosis.

Objective: We sought to determine the clinical outcomes of patients undergoing surgical aortic valve replacement with hemodynamically confirmed severe pulmonary hypertension and aortic stenosis and compare them with the outcomes of patients not undergoing aortic valve replacement and patients undergoing aortic valve replacement with mild-to-moderate pulmonary hypertension.

Methods: A total of 317 patients with severe aortic stenosis (aortic valve area < 1 cm(2)) underwent right heart catheterization along with left heart catheterization between 2004 and 2009. Severe pulmonary hypertension (mean pulmonary artery pressure > 35 mm Hg) was present in 81 patients, of whom 35 (43.

Safety and efficacy of carotid stenting in individuals with concomitant severe carotid and aortic stenosis.

Aims: Carotid artery stenting (CAS) prior to open-heart surgery may be a useful approach to minimise the risk of neurologic events in patients undergoing aortic valve replacement (AVR).

Methods And Results: All patients referred for carotid intervention at our institution between 1998 and 2005 with concomitant severe aortic stenosis (AS) (aortic valve area <1.0 cm2) were included.

Limitations of angiography for the assessment of renal artery stenosis and treatment implications.

Renovascular hypertension due to atherosclerotic renal artery stenosis is the most common cause of secondary hypertension. Percutaneous catheter-based renal artery revascularization has been increasingly utilized for the treatment of renal artery stenosis. Renal artery stenting has a high technical success rate, but the rate of improvement in hypertension is somewhat less than expected with this technique.

Drug-eluting stent fracture and acute coronary syndrome.

Background: Coronary stent fracture is an underrecognized entity but has been reported more frequently in the drug-eluting stent (DES) era. Nevertheless, the clinical implications of coronary stent fracture remain unclear.

Methods And Materials: A literature search for reports of DES fracture was conducted via MEDLINE, and the US Food and Drug Administration Manufacturer and User facility Device Experience (MAUDE) database was accessed via the internet and interrogated for reports of stent fracture between January 1, 2003, and April 30, 2008.
