BACKGROUND: The PSP (predilatation, sizing, post-dilatation)-technique was developed to improve the prognosis of patients after bioresorbable vascular scaffold (BVS) implantation. In acute coronary syndrome (ACS) the use of BVS is particularly demanding and carries some potential risk regarding aggressive lesion preparation, proper vessel sizing due to spasm and thrombus inside the artery. The aim herein, was to determine the long-term results of BVS stenting in ACS patients depending on the scaffold implantation technique...

Salvior Mok, David Majdalany, Gosta B Pettersson
Background: Myocardial bridge is defined as a segment of a coronary artery that takes an intramyocardial course. The presence of myocardial bridge has been observed in as many as 40%-80% of cases on autopsy, angiographically from 0.5% to 16.0%, and often asymptomatic. However, it has been associated with angina, coronary spasm, myocardial infarction, arrhythmias, syncope, sudden cardiac arrest, and death. Conflicting opinions exist on the timing of surgical intervention for myocardial bridge...

Although primary hemifacial spasm (HFS) is mostly related to a vascular compression of the facial nerve at its root exit zone (REZ), its occurrence in association with distal, cisternal portion has been repeatedly reported during the last two decades. We report two patients with typical HFS caused by distal neurovascular compression, in which the spasm was successfully treated with microvascular decompression (MVD). Vascular compression of distal, cisternal portion of the facial nerve was identified preoperatively in the magnetic resonance imaging (MRI)...

Impaired glucose metabolism is associated with an increased risk of cardiovascular complications, and coronary artery spasm is thought to underlie the development of coronary artery disease. Intraday glucose variability (GV) accelerates oxidative stress and inflammatory cytokine release, but its impact on coronary artery spasm remains unclear. This study investigated the relationship between intraday GV and coronary artery spasm. The study included 50 patients with dysglycemia and suspected coronary spastic angina...

BACKGROUND: The transradial approach (TRA) to endovascular procedures decreases access site morbidity and mortality in comparison with the traditional transfemoral technique (TFA). Despite its improved safety profile, there is a concern that TRA is less favorable for neurointerventional procedures that require large coaxial systems to manage the small tortuous cerebral vessels. OBJECTIVE: To report our experience with TRA for flow diverter placement for treatment of unruptured cerebral aneurysms...

INTRODUCTION: Management of vascular malformations requires microcatheter manipulation through distal tortuous arterial feeders less than a millimetre in diameter, to permit safe and effective embolization at the fistula or nidus location. The Asahi ChikaiTM 0.008 inch micro-guidewire recently introduced in the United States was used to evaluate microcatheter torque, support and safety in distal microcatheter navigation. METHODS: The use of the Asahi Chikai 0.008 inch micro-guidewire in conjunction with flow-guided, and over the wire microcatheters was evaluated in 25 neuroendovascular cases over a 1 year period...

OBJECTIVE: An under-recognized cause of chest pain, the coronary slow-flow (CSF) phenomenon is characterized by delayed coronary opacification during diagnostic angiography in the absence of epicardial coronary artery disease (CAD). Given its angiographic resemblance to no-reflow during percutaneous coronary intervention, a condition associated with microvascular spasm responsive to calcium-channel blockers, we hypothesized that spontaneous CSF may similarly be reversed by intracoronary (IC) nicardipine...

Introduction: Various nerve compression syndromes, such as trigeminal neuralgia (TN), glossopharyngeal neuralgia (GN), and hemifacial spasm (HFS), are caused by compression of the concerned nerve by the adjacent vessel. Patients who do not respond to medical management are usually treated by "microvascular decompression (MVD) of the nerve." Teflon patch graft is the most commonly used material for MVD. This graft has been used in various shapes like a patch, in the shredded form, or as a sling...

Coronary artery spasm (CAS) is known to be a risk factor for cardiovascular events. However, there is limited data whether the multi-vessel and diffuse spasm (MVDS) is related to more adverse clinical outcomes compared to the Non-MVDS. The aim of this study is to evaluate the impact of the MVDS on clinical outcomes during a 3-year clinical follow-up period.A total 2797 patients underwent coronary angiography (CAG) with acetylcholine (ACH) provocation test from Nov 2004 to Oct 2010 were enrolled. It is a single-center, observational, prospective, all-comers registry designed to reflect the "real world" practic...

BACKGROUND AND PURPOSE: Hemi-laryngopharyngeal spasm is a recently discovered condition characterized by episodic coughing and unilateral throat contractions that may lead to severe stridor. These symptoms are caused by a vascular compression of the ipsilateral vagus nerve, typically the PICA. Microvascular decompression of the vagus nerve has been demonstrated to be a potential cure for this neurovascular compression syndrome. The main aim of this study was to clarify the role of MR imaging in the diagnostic work-up of this rare condition...

A 39-year-old woman with no coronary risk factors was admitted due to repetitive morning chest pain. Coronary angiography revealed subtotal occlusion of the distal obtuse marginal branch that was not recanalized by intracoronary nitroglycerin administration. Intravascular ultrasound and optical frequency domain imaging showed tandem intramural hematomas in the culprit vessel. We performed cutting balloon angioplasty successfully with dual intracoronary imaging modality guidance. The 4-month follow-up angiography revealed favorable vascular healing and the provocation test induced multiple spasms, including in the culprit vessel, by intracoronary acetylcholine administration...

Coronary spastic angina (CSA) is relatively more common in young people than in elderly people. Here, we present three cases of elderly male patients who experienced out-of-hospital cardiac arrest (OHCA) likely due to coronary spasm-induced ventricular fibrillation (Vf) from 2013 to 2016. After defibrillation, emergency coronary arteriography demonstrated severe coronary vasospasm that resolved following intracoronary infusion of nitroglycerin in the right coronary arteries in all three patients, with no organic obstructive lesion in the coronary arteries after nitroglycerin infusion...
