Right coronary artery arising from pulmonary trunk: assessment with conventional coronary angiography and multislice computed tomography coronary ang…

2009

We present a case of a 59-year-old man who was admitted to the hospital because of atypical chest pain and dyspnea. Conventional coronary angiography showed an anomalous origin of the right coronary artery from the pulmonary trunk. The patient underwent multislice computed tomography in order to clarify the origin and course of the anomalous vessel. The aim of this report is to emphasize the role of multislice computed tomography as an accurate noninvasive imaging tool in the evaluation of coronary artery anomalies.

Valoración no invasiva de injertos aortocoronarios y coronarias nativas con tomografía computarizada de 64 detectores: comparación con la coronariogr…

2010

Introduccion y objetivos Aunque la tomografia computarizada (TC) multidetector muestra una elevada exactitud diagnostica en la valoracion no invasiva de las arterias coronarias e injertos, son escasos los trabajos que valoren su fiabilidad en el estudio conjunto de vasos nativos, injertos y vasos distales a las anastomosis. El objetivo de este estudio es valorar la exactitud diagnostica de la TC de 64 detectores en la valoracion de injertos coronarios y arterias coronarias nativas. Metodos Se estudia con TC de 64 detectores a 36 pacientes revascularizados quirurgicamente e indicacion clinica de evaluacion angiografica de sus injertos. Se analizo la exactitud diagnostica de la TC para la det…

Response by Meneveau and Ecarnot to Letter Regarding Article, “Optical Coherence Tomography to Optimize Results of Percutaneous Coronary Intervention…

2017

We read with interest the letters by Vallurupalli and Uretsky and also Dr Nadir relating to the results of the DOCTORS study (Does Optical Coherence Tomography Optimize Results of Stenting).1 We thank the authors for their insightful remarks. Vallurupalli and Uretsky raise an interesting point when they underline that a prolonged inflation time is superior to a rapid inflation/deflation technique in terms of both stent expansion and apposition. We acknowledge that we did not take stent inflation time into account in the case report form of the DOCTORS study. The arguments put forward by Vallurupalli and Uretsky suggest that this variable should be systematically recorded and reported. Howev…

Low dose CT of the heart: a quantum leap into a new era of cardiovascular imaging.

2010

In 10 years, computed tomography coronary angiography (CTCA) has shifted from an investigational tool to clinical reality. Even though CT technologies are very advanced and widely available, a large body of evidence supporting the clinical role of CTCA is missing. The reason is that the speed of technological development has outpaced the ability of the scientific community to demonstrate the clinical utility of the technique. In addition, with each new CT generation, there is a further broadening of actual and potential applications. In this review we examine the state of the art on CTCA. In particular, we focus on issues concerning technological development, radiation dose, implementation,…

Severe iatrogenic admissions in a coronary care unit:

2013

Introduction: Iatrogenic complications are defined as adverse drug reactions or complications induced by non drug interventions, such as cardiac devices or stimulation techniques. Iatrogenic complications occurring during hospital stay are known to be associated with increased hospital length of stay and mortality. Only few data are available on iatrogenic as cause of hospital admission, particularly in coronary care unit. In patient admitted in coronary care unit for iatrogenic, we aimed a) to analyse their prevalence, type and characteristics, b) to analyse their in-hospital length of stay and mortality and c) to evaluate the predictive factors of severity and mortality. Methods: From 1st…

Anatomical variants and anomalies of the coronary tree studied with MDCT coronary angiography

2010

Le anomalie delle arterie coronariche sono presenti alla nascita nella maggior parte dei casi asintomatiche ma possono manifestarsi con sintomatologia severa quale angina pectoris o addirittura l’arresto cardiaco. L’angiografia coronarica mediante tomografia computerizzata multistrato (TCMS) permette, tramite ricostruzioni multiplanari secondo piani curvilinei e riformattazioni 3D, la visualizzazione dell’albero coronarico e delle sue varianti ed anomalie in maniera non invasiva, fornendo migliore e più accurata alternativa alla angiografia coronarica (AC). Lo scopo di questo pictorial consiste nella descrizione mediante immagini TCMS con ricostruzioni multiplanari e 3D delle principali var…

Intraluminal Doppler-Sonography: Analysis and “in Vitro Test” of a New Device

1992

In treating patients with coronary heart disease it’ s necessary first to determine what influence the stenose has on the coronary blood flow. This is a prerequisite for any invasive treatment method. Coronary angiography explosures are only partially useful in attaining a functional evaluation of the haemodynamic stenoses.

Long-term outcome of patients with NSTEMI and nonobstructive coronary arteries by different angiographic subtypes

2021

Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes.We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortal…
