English Bulldogs (EB) with pulmonic stenosis (PS) sometimes have an aberrant coronary artery (CA) type R2A encircling the pulmonary artery (PA). Balloon valvuloplasty (BV) is treatment of choice for severe PS, but is considered to be contraindicated in dogs with aberrant CA. Conservative BV in EB with aberrant CA is ...

Transcatheter balloon pulmonary valvuloplasty (BPV) is considered to be the treatment of choice for neonates with critical pulmonary valvar stenosis (PVS) or pulmonary valvar atresia with intact ventricular septum accompanied by reasonable right ventricular volume. The percutaneous femoral venous access is the most preferred route for BPV in most cardiac ...

We occasionally encountered difficult cases of balloon and stent delivery to the distal lesion because of narrow stent strut, severe calcification, or tortuosity of the proximal section. We describe a new technique to deliver balloon, stent, and guiding catheter to the distal lesion using a distal balloon deflation. This technique ...

Previous studies have shown that stenosis of the arterial anastomosis of thrombosed hemodialysis (HD) grafts, unmasked after conventional thrombectomy, very often necessitate subsequent arterial angioplasty. The aim of this study was to describe a novel fluoroscopic-assisted balloon thrombectomy technique which permits simultaneous arterial angioplasty (should this is required) for thrombosed ...

The present report describes the case of a 77-year-old man with unstable angina, in which the culprit vessel was extremely angulated and precluded placement of a guidewire for subsequent coronary interventions. A novel technique is reported, using an undersized, uninflated and distally placed balloon catheter, which easily facilitated guidewire placement.

We proposed a novel laser-driven short-term heating angioplasty to realize restenosis-suppressive angioplasty for peripheral artery disease. In this study, we investigated the chronic intimal hyperplasia formation after the short-term heating dilatation in vivo, as well as the thermal damage calculation on arterial smooth muscle cells (SMCs). The prototype short-term heating ...

Ureteral stenting is a routine, minimally invasive procedure performed for relief of benign or malignant obstruction. In case of ureteral stenosis, to allow a correct insertion of the stent, a predilatation of the ureter stenosis with a conventional balloon catheter can be necessary. In exceptional cases, it can be difficult ...

Plasma levels of brain natriuretic peptide (BNP) have been shown to correlate to aortic stenosis severity and are predictive of symptom development and survival. They also predict postoperative outcomes after valve replacement in patients with aortic stenosis. The early evolution of N-terminal-pro-BNP (NT-pro-BNP) levels after 50 aortic balloon valvuloplasty procedures ...

There is little information about the relationship between balloon inflation time and sirolimus-eluting stent (SES) expansion. In this randomized intravascular ultrasound (IVUS) study, 92 de novo lesions in native coronary arteries that underwent SES implantation were enrolled. Sirolimus-eluting stent was implanted using an inflation pressure of 14 atm. Stent balloon ...

Treatment with percutaneous extracorporeal mechanical assist devices provides the ultimate therapeutic option to improve the macrocirculation in patients suffering from refractory cardiac arrest, severe cardiogenic shock or during high-risk interventions. However, the flow in the smallest vessels in these critical periods is poorly understood but prognostically of high importance. Using ...

This study evaluated the efficiency and feasibility of dilatable bands in selected patients. Two types of dilatable handmade bands were retrospectively evaluated and divided into two groups: main pulmonary artery bands and bilateral branch pulmonary artery bands (hybrid stage I palliation). Stepwise balloon angioplasty (BA) was performed, increasing the diameter ...

AIM: Almost all cross-clamps utilized in vascular surgery, even atraumatic clamps, have been shown to cause mechanical damage to the vascular wall. In recent years, surgical procedures using an endoluminal balloon technique have been reported as an alternative occlusion strategy. This study discusses the histopathological characteristics and comparison between vascular ...

This article investigates the mechanics of balloon dilatation in the treatment of bronchotracheal stenosis. The "scar stricture"-type stenosis examined in this paper is typically dilated manually, using a dilatation balloon. If indicated, this is followed by stent implantation. The selection of the stent with proper characteristics is performed empirically, based ...

The T technique is not uncommonly used to stent bifurcation lesions. It requires recrossing into the side branch with a guidewire and balloon to perform final Kissing Balloon dilations, but recrossing can be difficult. We describe a case of bifurcation stenting where balloon recrossing following guidewire placement into the side ...

INTRODUCTION: Cryothermal, HIFU, and laser catheter-based balloon technologies have been developed to simplify ablation for AF. Initial enthusiasm for their widespread use has been dampened by phrenic nerve (PN) injury. The interaction between PN and pulmonary vein (PV) geometry contributing to PN injury is unclear. METHODS AND RESULTS: After right ...

We report a patient with traumatic carotid-cavernous fistula associated with an isolated internal carotid artery in whom, after trans-arterial balloon embolisation, premature balloon detachment occurred with balloon migration to the supraclinoid carotid artery, leading to total occlusion of the blood flow. The carotid flow was eventually restored by direct puncture ...

Percutaneous bifurcation intervention is usually sufficient with a single-stent strategy. When the double-stent strategy is employed, higher restenosis and target lesion revascularization (TLR) rates are observed, especially at the side-branch ostium. The results may be improved, however, with refinement in techniques, for example, final kissing balloon inflation and double kissing ...

BACKGROUND: Some lesions can be very difficult to reach, especially if acute angles and/or multiple turns "protect" access. Once reached, the guiding system needs to give sufficient support for balloons or stents to be deployed. METHODS: A "telescopic" system was created consisting of: (1) a microcatheter with guidewire. This system ...

The treatment of acute limb ischemia is always challenging. Various techniques including balloon angioplasty, rheolytic thrombectomy, and prolonged localized infusion of thrombolytics are often used to achieve revascularization. However, some patients with suboptimal angiographic results may benefit from novel alternatives such as the Clearway irrigation balloon (Atrium, Hudson, NH, USA). ...
