Renal Denervation With Sterile Irrigated Deflectable Ablation Catheter Used in Renal Artery in Primary Hypertension

The purpose of this study is to assess the safety and efficacy of renal denervation with sterile irrigated deflectable ablation catheter used in renal artery in primary hypertension in Chi...

Renal Denervation Therapy in Hypertensive Patients Undergoing A-Fib Ablation

We propose a pilot study to assess safety and benefit of renal artery ablation at the time of planned atrial fibrillation ablation.

Renal Artery Stenting in Patients With Documented Resistant Hypertension and Atherosclerotic Renal Artery Stenosis (ANDORRA)

The ANDORRA study is a, multicenter, prospective, open, randomized, controlled blinded endpoint trial (PROBE) comparing two treatment strategies (renal artery stenting + standardized and o...

Prevalence of Renal Artery Stenosis in Patients Referred for Cardiac Catheterization

All patients referred for coronary angiography will simultaneously be evaluated for renal artery stenosis and then stenosis more than 50% will be analyzed according to clinical conditions,...

A Study to Evaluate Safety and Efficacy of the Redy™ Renal Denervation System in the Treatment of Patients With Uncontrolled Hypertension

Development of a Simple Risk Score Model to Predict Renal Artery Stenosis.

Renal artery stenosis (RAS) is a known cause of secondary hypertension and renal failure. Although renal artery angiography is the gold standard for diagnosing RAS, a simple method to estimate if pati...

Renal artery fibromuscular dysplasia and its effect on the kidney.

Fibromuscular dysplasia is a heterogeneous group of systemic, noninflammatory, and nonatherosclerotic diseases of the vascular wall. It is the second-most common abnormality of the renal artery. Altho...

Renal arterial atherothrombosis due to catheter-induced dissection: Necessity of urgent intervention in a patient with a solitary functioning kidney.

Renal artery stenosis (RAS) is a leading cause of hypertension, renal failure, pulmonary edema, and loss of renal mass. Atherothrombotic renal disease is a well-described entity, known primarily for i...

Morphological and functional renovascular changes as cause of resistant arterial hypertension - case report and literature review.

Resistant hypertension is defined by the inability to maintain within normal limits the blood pressure values of an individual, while he is under treatment with maximal tolerated doses of three antihy...

Evaluation of later morphologic alterations in renal artery wall and renal nerves in response to catheter-based renal denervation in sheep: comparison of the single-point and multiple-point ablation catheters.

This study evaluated the subacute morphologic alterations in renal artery wall and renal nerves in response to catheter-based renal denervation in sheep and also compared the efficiency of single-poin...

Medical and Biotech [MESH] Definitions

Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).

Left RENAL VEIN compression between the AORTA, ABDOMINAL and the SUPERIOR MESENTERIC ARTERY. Variable symptoms include HYPERTENSION, RENOVASCULAR; HEMATURIA; and VARICOSE VEINS.

Persistent high BLOOD PRESSURE due to KIDNEY DISEASES, such as those involving the renal parenchyma, the renal vasculature, or tumors that secrete RENIN.

Hypertension due to RENAL ARTERY OBSTRUCTION or compression.

Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.
