An angiographic analysis of 10 cases of univentricular heart of the right ventricular type is reported. This congenital malformation is characterized by a large chamber with right ventricular morphology that receives both atrioventricular valves, and a second, smaller chamber, a trabecular pouch, with left ventricular morphology. These chambers are separated by a posterior septum but are connec...

BACKGROUND AND PURPOSE This study sought to determine the frequency of noncircular lumens in patients with significant carotid atherosclerotic disease and to evaluate the effect of noncircular lumens on stenosis measurement derived from angiographic projections. METHODS One hundred consecutive patients presenting with an internal carotid artery stenosis of at least 50% were imaged with spiral...

Periprocedural myocardial infarction (MI) can be induced by several angiographic mechanisms. However, there are limited data on whether these mechanisms differentially affect clinical outcomes. The purpose of our study was to investigate the impact of periprocedural MI on mortality according to the underlying angiographic mechanisms after drug-eluting stent (DES) implantation. We pooled the dat...

BACKGROUND Acute gastrointestinal bleeding (GIB) is a life-threatening abdominal emergency and can be treated by transarterial embolization (TAE). Rehemorrhage and poor outcome are associated with several clinical factors. This study investigated the clinical and angiographic parameters associated with treatment failure for patients with acute GIB undergoing TAE. METHODS Sixty-seven patients ...

AIMS Angiographic guidance for percutaneous coronary intervention (PCI) has substantial limitations. The superior spatial resolution of optical coherence tomography (OCT) could translate into meaningful clinical benefits. We aimed to compare angiographic guidance alone versus angiographic plus OCT guidance for PCI. METHODS AND RESULTS Patients undergoing PCI with angiographic plus OCT guidanc...

Introduction: Age-related Macular Degeneration (AMD) is one of the most important causes of irreversible  blindness in the developed world and  prevents the affected  person from  performing simple tasks such  as  reading,  driving  and  facial  recognition.  In  the  AMD,  new  blood  vessels  grow  underneath  the  retina  in  a  process  called  choroidal  neovascularisation  (CNV).  There  ...

BACKGROUND It has been shown recently that postangioplasty coronary flow reserve and the degree of residual stenosis have a modest predictive value for short- and long-term clinical outcomes after coronary angioplasty. Corrected TIMI frame count (CTFC) is a simple quantitative index of coronary blood flow. Its relationship with Doppler coronary flow velocity and clinical outcome after coronary ...

Patients with restenosis after coronary artery stent implantation may present with recurrent ischaemia, stable angina, and acute coronary syndromes. Restenosis may also be asymptomatic (without ischaemia), detected only on repeat angiography. Previous studies have demonstrated that angiographic measures including both in-stent and in-segment late loss and percentage diameter stenosis are valid ...

BACKGROUND Coronary angiography is frequently employed to aid in the diagnosis of acute coronary thrombosis, but there is limited data to support its efficacy. The aim of the study was to evaluate sensitivity and specificity of five commonly used angiographic characteristics for diagnosis of acute coronary thrombosis: Ambrose complex lesion morphology; spherical, ovoid, or irregular filling def...

PURPOSE Currently, insufficient data exist to evaluate the relationship between angiographic late loss (LL) and long-term clinical outcome after drug-eluting stent (DES) implantation. In this study, we hypothesized that angiographic LL between 0.3 and 0.6 mm correlate with favorable long-term clinical outcomes. MATERIALS AND METHODS Patients were enrolled in the present study if they had unde...
