Endovascular Treatment of a Popliteal Artery Aneurysm Via Transpedal Approach: A Case Report.

Popliteal artery aneurysm (PAA) has been increasingly treated with endovascular intervention in recent years. However, whether transpedal access can be utilized to treat PAA has not been widely reported. We report a case of successful treatment of a PAA with a covered stent via retrograde transpedal approach in an 80-year male with prohibitive surgical risk who initially failed antegrade approach.

Transpedal approach for iliac artery stenting: A pilot study.

Objective: To demonstrate the safety and feasibility of the transpedal approach as an alternate arterial access site for iliac artery intervention.

Background: The common femoral artery is the traditional access site for the endovascular treatment of iliac artery stenoses. However, this approach is associated with complication rates as high as 2%, including retroperitoneal bleeding which carries high patient morbidity and mortality.

Feasibility and Safety of Routine Transpedal Arterial Access for Treatment of Peripheral Artery Disease.

Objective: To demonstrate the feasibility and safety of transpedal arterial access for lower-extremity angiography and intervention.

Background: Traditionally, the femoral artery is chosen for the initial access site in symptomatic peripheral artery disease (PAD), but this approach carries a substantial portion of the entire procedural complication risk.

Methods: 80 patients were prospectively evaluated for the treatment of PAD between May and July 2014.

Tips and tricks for antegrade recanalization of chronic total occlusions using the CrossBoss catheter.

Objectives: To provide new strategies and techniques for the successful recanalization of chronic total occlusions (CTOs) with the sole use of the CrossBoss catheter. In addition, some common CTO scenarios are illustrated in detail.

Background: CTOs are one of the most challenging complex coronary lesion subsets to intervene upon.

The utility of extension catheters in transradial percutaneous coronary intervention.

Objectives: To evaluate the use of extension catheters in transradial intervention of complex coronary lesions.

Background: Complex percutaneous coronary intervention (PCI) via transradial approach remains a challenge for many interventionalists, primarily due to the difficulty in obtaining adequate guide catheter support.

Methods: A retrospective case series identified 54 patients who presented for PCI of complex coronary lesions.

Mortality in the coronary care unit.

Objectives: Currently, there are limited data on mortality or predictors of survival for patients admitted to the coronary care unit (CCU). The purpose of this study was to provide data on mortality in the modern-day CCU and to better define factors influencing patient survival.

Methods: A survey was conducted of all patients admitted to CCUs in New York City metropolitan academic hospitals in 2011, followed by a retrospective analysis comparing clinical data from 59 nonsurvivors with those from 897 survivors at two representative institutions.

A novel technique in the use of fractional flow reserve in coronary artery bifurcation lesions.

The side branch (SB) in bifurcation lesions is a frequently encountered challenge that interventional cardiologists must face. There is great interest in determining fractional flow reserve (FFR) in the SB to help guide treatment decisions; however, difficulty with the pressure guidewire limits its widespread use. We propose a novel technique that will ease the incorporation of FFR in routine evaluation of bifurcation lesions, and allow better assessment of provisional stenting and need for SB intervention.

Transulnar catheterization in patients with ipsilateral radial artery occlusion.

Background: The transradial approach to percutaneous coronary intervention (PCI) has recently gained popularity among interventionalists. However, radial artery occlusion (RAO) limits the ability for repeat catheterization. In current practice, transulnar catheterization is thought to be a contraindication in patients with ipsilateral RAO.

Balloon-assisted sheathless transradial intervention (BASTI) using 5 Fr guiding catheters.

Background: The sheathless approach to transradial percutaneous coronary intervention (PCI) has recently gained popularity among interventionalists. However, technical problems and lack of approved equipment in the United States has limited its applicability. We describe a new approach, balloon-assisted sheathless transradial intervention (BASTI) that can ease the use of 5 Fr sheathless guiding catheters and decrease complication rates.

Prevention of contrast-induced nephropathy: A randomized controlled trial of sodium bicarbonate and N-acetylcysteine.

Background: Contrast-induced nephropathy (CIN) continues to be a common cause of acute renal failure in high-risk patients undergoing radiocontrast studies. However, there is still a lack of consensus regarding the most effective measures to prevent CIN.

Methods: ONE HUNDRED EIGHTEEN PATIENTS WITH DIABETES MELLITUS AND/OR RENAL INSUFFICIENCY, SCHEDULED FOR CORONARY ANGIOGRAPHY OR INTERVENTION, WERE RANDOMLY ASSIGNED TO ONE OF FOUR TREATMENT GROUPS: intravenous (IV) 0.
