A giant mediastinal teratoma: From diagnosis to complete resection and restitutio ad integrum.
The current report highlights the integrated work-up of an unexpected giant mediastinal teratoma in 28 years old female. A comprehensive multi-modality imaging approach was implemented in order to define the diagnosis and tailor the most appropriate surgical intervention
Successful surgical repair of left ventricular pseudoaneurysm in a patient with subacute ST-elevation myocardial infarction.
We report a successful surgical repair of left ventricular pseudoaneurysm in a patient with subacute ST-elevation myocardial infarction (STEMI). In the case of expansion of the infarct related ventricular wall, early (within 24 hours) or late (3-5 days after STEMI) cardiac rupture should be always borne in mind in order to proceed to life saving prompt surgical repair

Novel antithrombotic strategies in cardiovascular diseases
Ishemic cardiovascular diseases represent the most common cause of mortality and morbidity in the western world, and atherothrombosis occupies a central role in their pathophysiology. Venous thrombi, which form under low shear conditions, are predominantly composed of fibrin and red cells, while arterial thrombi form under high shear conditions and are composed primarily of platelet aggregates held together by fibrin strands. Several successful strategies targeting specific steps in coagulation and platelet function or interaction have been developed to prevent or treat atherothrombotic disorders. Intense research is currently underway in an effort to develop more safe and effective compounds, such that novel antithrombotics are emerging to target specific steps in the coagulation cascade, as well as in pathways of platelet adhesion, activation and aggregation. This review will focus on the recent advances in research in this fast-evolving field. © The Thomson Corporation
Local vascular dysfunction after coronary paclitaxel-eluting stent implantation
BACKGROUND: Paclitaxel-eluting stents (PES) have been shown to reduce the rate of restenosis and the need for repeated revascularization procedures compared with bare metal stents. However, long-term effects of paclitaxel on vascular function are unknown. The purpose of the present study was to assess coronary vasomotor response to exercise after paclitaxel-eluting stent implantation. METHODS: Coronary vasomotion was evaluated by biplane quantitative coronary angiography at rest and during supine bicycle exercise in 27 patients with coronary artery disease. Twelve patients were treated with a bare metal stent (controls), and fifteen patients with a paclitaxel-eluting stent. All patients were restudied 6+/-2 (range 2-12) months after stent implantation. Minimal luminal diameter, stent diameter, proximal, distal and a reference vessel diameter were determined. RESULTS: Reference vessels showed exercise-induced vasodilation in both groups (+20+/-5% controls; +26+/-3% PES group). Vasomotion within the stented vessel segments was abolished. In the controls, the adjacent segments proximal and distal to the stent showed exercise-induced vasodilation (+17+/-3% and +24+/-4%). In contrast, there was exercise-induced vasoconstriction of the proximal and distal vessel segments adjacent to the paclitaxel-eluting stent (-13+/-6% and -18+/-4%; p<0.005). After sublingual nitroglycerin, the proximal and distal vessel segments dilated in both groups. Exercise-induced vasoconstriction adjacent to paclitaxel-eluting stent correlated inversely with the time interval after stent implantation. CONCLUSIONS: Paclitaxel-eluting stent implantation is associated with exercise-induced vasoconstriction in the persistent region suggesting endothelial dysfunction as the underlying mechanism. Improvement of vascular function occurs over time, indicating delayed vascular healing
Severe Stenosis of Mitral Bioprosthetic Valve Thrombosis in a Patient with HCV-Related Cirrhosis and Duodenal Variceal Bleeding: The Deadly Triad
: Bioprosthetic valve thrombosis (BPVT) is considered a relatively rare but life-threatening clinical entity. Thus, there is the need of high clinical suspicion in order to make a timely diagnosis and related appropriate therapeutic interventions. In this regard, the management of BPVT is high risk, whatever the option taken (surgery and/or systemic fibrinolysis). The presence of severe comorbidities-as decompensated cirrhosis-further complicates the clinical decision-making process, calling for a patient-tailored integrated multidisciplinary approach. We report a challenging case of a 45-year-old patient with mitral bioprosthetic valve thrombosis and hepatitis C virus (HCV)-related cirrhosis complicated by active duodenal variceal bleeding

Patient selection for transcatheter aortic valve replacement: A combined clinical and multimodality imaging approach
Transcatheter aortic valve replacement (TAVR) has been validated as a new therapy for patients affected by severe symptomatic aortic stenosis who are not eligible for surgical intervention because of major contraindication or high operative risk. Patient selection for TAVR should be based not only on accurate assessment of aortic stenosis morphology, but also on several clinical and functional data. Multi-Imaging modalities should be preferred for assessing the anatomy and the dimensions of the aortic valve and annulus before TAVR. Ultrasounds represent the first line tool in evaluation of this patients giving detailed anatomic description of aortic valve complex and allowing estimating with enough reliability the hemodynamic entity of valvular stenosis. Angiography should be used to assess coronary involvement and plan a revascularization strategy before the implant. Multislice computed tomography play a central role as it can give anatomical details in order to choice the best fitting prosthesis, evaluate the morphology of the access path and detect other relevant comorbidities. Cardiovascular magnetic resonance and positron emission tomography are emergent modality helpful in aortic stenosis evaluation. The aim of this review is to give an overview on TAVR clinical and technical aspects essential for adequate selection
