Background: Chronic total occlusions with ambiguous proximal caps present a significant challenge in endovascular interventions of patients with Buerger's disease.

Objective: We aimed to evaluate the effectiveness of transpedal retrograde wire just marker technique in patients with Buerger's disease presenting proximal cap ambiguity and flush occlusions.

Transcoronary Gradients of Mechanosensitive MicroRNAs as Predictors of Collateral Development in Chronic Total Occlusion.

: In this present study, we investigated the impact of mechanosensitive microRNAs (mechano-miRs) on the collateral development in 126 chronic total occlusion (CTO) patients, selected from 810 undergoing angiography. : We quantified the collateral blood supply using the collateral flow index (CFI) and assessed the transcoronary mechano-miR gradients. The patients with favorable collaterals had higher CFI values (0.

A novel troubleshooting technique for below-the-knee artery occlusions with proximal cap ambiguity: Transpedal Retrograde Wire Just Marker Technique.

Background: Chronic total occlusions with ambiguous proximal caps pose a challenging problem in below-the-knee artery endovascular interventions.

Case Report: We defined a new technique for antegrade puncture and penetration of an ambiguous proximal cap in a 52-year old male patient with a non-healing wound on his right forefoot. Anterior tibial artery (ATA) was determined as the target vessel; however, its origin and course could not be determined.

A randomized trial comparing left distal radial versus femoral approach for coronary artery bypass graft angiography: a pilot study.

Background: Left distal transradial angiography (ldTRA) is a new technique for radial coronary angiography and may be an alternative to conventional transfemoral angiography (TFA) in patients who had previously undergone coronary artery bypass graft (CABG) surgery. In this study we compared ldTRA with TFA in patients who had undergone CABG surgery in terms of procedural details.

Methods: Fifty-seven consecutive patients with history of previous CABG among 459 patients who were admitted to coronary angiography unit (elective and acute coronary syndromes) in our center between October 2019 and February 2020 were included in the study.

Percutaneous angioplasty in the treatment of thrombosed hemodialysis fistulas: A single-center experience with 1 year of follow-up.

Objective: Thrombosis of a hemodialysis arteriovenous fistula (AVF) is a serious complication that needs urgent treatment. Most cases are treated surgically, but recently, endovascular strategies have become a viable alternative. This study is an evaluation of the success and patency rate of percutaneous balloon angioplasty of thrombosed hemodialysis fistulas using a drug-coated balloon (DCB) contrasted with a standard balloon (SB).

[Turkish Cardiology Association Consensus Report: COVID-19 Pandemic and Cardiovascular Diseases (May 13, 2020)].

In December 2019, in the city of Wuhan, in the Hubei province of China, treatment-resistant cases of pneumonia emerged and spread rapidly for reasons unknown. A new strain of coronavirus (severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2]) was identified and caused the first pandemic of the 21st century. The virus was officially detected in our country on March 11, 2020, and the number of cases increased rapidly; the virus was isolated in 670 patients within 10 days.

The relationship between serum asymmetric dimethylarginine levels and radial artery spasm.

Objective: The use of the radial approach in coronary angiography or percutaneous coronary intervention has increased owing to its advantages over the femoral approach such as rapid patient mobilization and improved patient comfort. However, radial artery spasm (RAS) that occurs during the procedure is a crucial factor in transradial approach failure and access site switch. Asymmetric dimethylarginine (ADMA) is a naturally occurring, modified amino acid that inhibits nitric oxide (NO) production.

Percutaneous Coronary Intervention for Chronic Total Occlusion versus Percutaneous Coronary Intervention for Non-Complex Coronary Lesions: Is There a Different Impact on Thyroid Function?

Objective: This study assessed whether high levels of iodide administered during percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) differentially influenced thyroid function compared to PCI for non-complex coronary lesions.

Subjects And Methods: A total of 615 patients were enrolled in the study; 205 underwent elective PCI for CTO lesions (Group I) and 410 underwent elective PCI for non-complex lesions including non-CTO, non-bifurcation, non-calcified, and non-tortuous lesions (Group II). Patients were monitored for development of incidental thyroid dysfunction between 1 and 6 months after PCI.

Is trans-radial approach related to an increased risk of radiation exposure in patients who underwent diagnostic coronary angiography or percutaneous coronary intervention? (The SAKARYA study).

Objective: It is still debatable whether diagnostic coronary angiography (CA) or percutaneous coronary interventions (PCIs) increase radiation exposure when performed via radial approach as compared to femoral approach. This question was investigated in this study by comparison of dose-area product (DAP), reference air kerma (RAK), and fluoroscopy time (FT) among radial and femoral approaches.

Methods: All coronary procedures between November 2015 and November 2017 were assessed; and 4215 coronary procedures were enrolled in the study.

Percutaneous endovascular therapy for symptomatic chronic total occlusion of the left subclavian artery.

Introduction: Percutaneous endovascular therapy is an accepted and preferred procedure for symptomatic subclavian artery disease. However, the technical feasibility and effectiveness of treating chronic total occlusion of the subclavian artery with this approach is uncertain. We aimed to evaluate the initial and mid-term results of endovascular therapy for patients with symptomatic chronic total occlusion of the left subclavian artery.

Cutaneous analgesia before transradial access for coronary intervention to prevent radial artery spasm.

Aim: Transradial access (TRA) for coronary intervention is increasingly used in current clinical practice. The aim of the present study was to evaluate the hypothesis that cutaneous analgesia before TRA for coronary intervention at a puncture site 30 minutes before puncture can reduce patient discomfort and the incidence of radial artery spasm (RAS).

Methods: Patients (n=104) undergoing planned coronary interventions using TRA were prospectively randomized to receive either 1 mL of 1% lidocaine subcutaneously (n=52) (control group) or subcutaneous lidocaine plus 5% lidocaine cream (n=52) cutaneously 30 minutes before puncture (treatment group).

Comparison of closed-cell and hybrid-cell stent designs in carotid artery stenting: clinical and procedural outcomes.

Introduction: Carotid artery stenting (CAS) is a promising alternative to surgery in high-risk patients. However, the impact of stent cell design on outcomes in CAS is a matter of continued debate.

Aim: To compare the periprocedural and clinical outcomes of different stent designs for CAS with distal protection devices.

Altered Plasma MicroRNA Expression in Patients with Mitral Chordae Tendineae Rupture.

Background: Mitral chordae tendineae rupture (MCTR) is a progressive disorder which leads to severe mitral regurgitation. Despite its importance, the precise pathogenetic mechanism of MCTR remains unclear. The study aim was to investigate the expression profile of circulating microRNAs (miRNAs) as being potentially involved in the development of MCTR.

Endovascular Treatment of Renal Artery Stenosis due to Fibromuscular Dysplasia - Is Stent Implantation Underused in this Circumstance?

Fibromuscular dysplasia (FMD) is a nonatherosclerotic and noninflammatory arterial disease that commonly affects the renal and carotid arteries. The primary target in treating patients with renal artery FMD is the control of blood pressure in order to prevent end-organ damage, which can be caused by poorly controlled hypertension. Invasive endovascular treatment should be taken into consideration both when hypertension cannot be controlled with medication.
