Reference diameter of coronary vessels at the site of lesions treated by stenting is significantly influenced by a variety of characteristics. We hypothesize that the treated segment size of patients undergoing stenting ultimately reflects the conjoint effect of several different factors, including constitutional, anatomical, and clinical features.

Being able to accurately choose an optimal view for stent positioning, non foreshortened length and to avoid side branches is imperative during therapeutic procedures. Traditional imaging limitations may include the selection of an incorrectly sized stent, inaccurate placement, and/or the need for additional stents. With the use of newer acquisition techniques and three-dimensional (3-D) modeling/reconstructions this can be minimized. We present a case in which with the assistance of 3-D and its computer derived optimal view, and optimal length, a significant amount of vessel foreshortening was eliminated therefore improving the procedural outcome.

In conclusion it may be stated that CFR and aortic distensibility indices can be evaluated simultaneously by stress TEE in HC patients. CFR and aortic distensibility were impaired in HC patients as compared to NC subjects.

DTI evaluation of tricuspid annular motion during dobutamine infusion in repaired TOF correlates with d P /d t and RV stroke volume and may help in assessing RV function and reserve.

We present a case of a 63-year-old man who was admitted to the hospital due to an acute coronary syndrome. Angiographic and magnetic resonance angiography examination showed an abnormal right vertebral artery originating from the ascending aorta, just above the left coronary sinus Valsalva in addition to aberrant retro-esophageal right subclavian artery. The variations and the incidence of various abnormal origins of the right vertebral artery are also reviewed.

Congenital ventricular diverticulum is a rare cardiac abnormality, frequently associated with other cardiac or non-cardiac congenital malformations. Clinically, congenital ventricular diverticulum may be asymptomatic or cause systemic embolization, heart failure, ventricular rupture, ventricular arrhythmia and sudden death. Cardiac magnetic resonance (CMR) can be a useful non-invasive and non-ionizing method to confirm the presence, size and extent of left ventricular (LV) diverticulum and its tissue characterization. In these reports we documented the presence of six diverticuli in patients underwent to CMR for other clinical indications. In all the cases, magnetic resonance showed an accurate assessment of diverticuli.

Endovascular stent graft treatment for treatment of thoracic aorta aneurysm, Type B dissection and traumatic disease of the thoracic aorta is technically feasible. Although the short and mid-term results are encouraging the long term results will determine the future of this treatment.
