1. Avaliação tardia dos stents liberadores de Biolimus A9® pela tomografia de coerência óptica: análise da cobertura tecidual e da aposição das hastes / Long-term follow-up Biolimus A9TM stents with optical coherence tomography: strut apposition and tissue coverage analysis
Introduction: First generation drug-eluting stents (DES) have emerged as a strategy to prevent in-stent restenosis and the need of target-vessel revascularization when compared to bare metal stents (BMS); but at the expense of a higher risk of very late stent thrombosis (ST). Uncovered and malapposed struts may be associated with both late and very late ST.

2. Influence of routine assessment of fractional flow reserve on decision making during coronary interventions / Influência da avaliação rotineira do fluxo fracionado de reserva durante intervenções coronárias percutâneas na estratégia terapêutica
BACKGROUND: In complex and multivessel coronary artery disease, it is often difficult to assess which lesions are associated with reversible ischemia and should be stented. Fractional flow reserve (FFR) is a well established methodology to indicate which lesions are culprit or not. Yet, frequently the selection of lesions to be stented is based on the angiog

3. Reliability of the interpretation of coronary angiography by the simple visual method
OBJECTIVE: Evaluation of inter and intraobserver reproducibility of by the visual method interpretation of cineangiogram in a clinically based context. METHODS: Five interventional cardiologists analyzed 11 segments of 8 coronary cineangiograms at a two month apart sessions. The percent luminal reduction by the lesions were analyzed by two different classifi

4. Coronary angioscopy.
Coronary angioscopy will not replace angiography as the gold standard for imaging atherosclerotic coronary arteries. However, there may well be a clinical niche for a technology that gives accurate information regarding a specific lesion, if that information can be used to improve the acute or chronic outcome of an interventional procedure. Our experience de

5. Maldevelopment of conotruncal and aorto-pulmonary septum with absent left central pulmonary artery: anatomical and clinical implications.
In a patient with pulmonary valve atresia with hypoplastic main pulmonary artery selective angiography showed absence of the central left pulmonary artery and a right pulmonary artery originating from the ascending aorta close to the left coronary artery. This unusual anatomical arrangement complicates interventional and surgical treatment.

6. New concepts for interpretation of intracoronary velocity and pressure tracings.
The development of quantitative angiography and the introduction of new imaging techniques cannot replace functional methods of assessing the severity of stenosis. Measurement of transstenotic pressure gradient and poststenotic flow velocity using miniaturised sensors with guidewire technology offers an alternative to the conventional non-invasive methods th

7. Three‐dimensional CT scanning: a new diagnostic modality in congenital heart disease
New generation multislice CT technology has changed the approach to non‐invasive assessment of congenital heart disease, in both paediatric and adult patients. This is mainly because of rapid advances in spatial and temporal resolution and in post‐processing capability. At Hôpital Necker‐Enfants Malades, CT with multiplanar and three‐dimensional rec

8. Can early closure and restenosis after endoluminal stenting be predicted from clinical, procedural, and angiographic variables at the time of intervention?
OBJECTIVES--To develop a statistical model to assess the risk of early closure and restenosis on the basis of the information available at the time of stent implantation. DESIGN--An exploratory forward, stepwise multivariate logistic regression for each adverse event and multivariate polychotomous analysis for both events. SETTING--Tertiary referral centre f
