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…
Coronary Slow Flow in a Patient with Myocarditis
2016
A young patient presented with dyspnea and high troponin. Coronary angiography excluded a diagnosis of CAD, but was diagnostic for the presence of coronary slow flow. Thermodilution showed increased resting resistances in the presence of hypernormal CFR.
American College of Cardiology/ European Society of Cardiology international study of angiographic data compression phase III
2000
AbstractOBJECTIVESWe sought to investigate up to which level of Joint Photographic Experts Group (JPEG) data compression the perceived image quality and the detection of diagnostic features remain ...

Clinical Appropriateness of Coronary Angiography
2012
Background: The study evaluates the appropriateness of coronary angiography and the agreement between the used method and the presence of coronary artery disease by the indications proposed from American College of Cardiology/American Heart Association (1999). Method: The guidelines allow us to associate to Class I and IIa the judgment of appropriateness, to the Class IIb of uncertainty; to Class III of inappropriateness. Result: On 761 coronary angiography 76.74% were appropriate, 23.13% unsuitable, 0.13% uncertain. The group with the greater value of appropriateness is that one with unstable angina (97.9% appropriate); that one with the lower value is the group with non-specific symptomat…
