Aortico-left ventricular tunnel is extremely rare congenital paravalvar communication between the aorta and the left ventricle. Usually it is treated surgically. In addition to the surgery the tunnel can be closed by percutaneous transcatheter intervention in appropriate patients. We present in this paper 7 months, 10 years, and 1,5 months ...

Percutaneous coronary intervention with stenting is widely used for ischemic heart disease. Because stent loss, which occurs rarely during the procedure, might have dire consequences, such as bleeding, stent embolism, acute myocardial infarction, emergency coronary artery bypass graft, and death, appropriate treatment is needed as soon as stent loss occurs. ...

A meta-analysis was performed to address the efficacy and safety of paclitaxel-eluting stent (PES) in ST-segment elevation myocardial infarction (STEMI) patients. A systematic literature search was conducted to identify all randomized clinical trials in mortality, recurrent myocardial infarction (rMI), repeat revascularization (RR), and stent thrombosis (ST). A total of 4190 ...

Patients who undergo coronary artery stent procedures are at risk for late atherothrombotic events, including stent thrombosis. The relationship between the duration during which evidence-based medical therapies are utilized after coronary artery stenting and the risk of late atherothrombotic events is not well characterized. In a retrospective cohort study linking ...

Drug-eluting stents (DES) have reduced restenosis following percutaneous coronary intervention (PCI), but they seem to be associated with increased coronary endothelial dysfunction compared to bare metal stents (BMS). No data are available about the prognostic value of exercise stress test (EST) in PCI patients in the DES era. The 160 ...

We sought to investigate stent lumen visibility of 56 coronary stents with the newest 256-multi-slice-CT (256-MDCT) technology for different reconstruction algorithms in an in vitro model. Early identification of in-stent restenosis (ISR) is important to avoid recurrent ischemia and prevent acute myocardial infarction (AMI). Since angiography has the disadvantage of ...

BACKGROUND: Drug-eluting stents (DESs) introduction has somewhat renewed the issues of strategy and stenting technique for treatment of bifurcation lesions. In particular, concerns remain on extensive use of DESs, especially in the side branch, and on time of dual antiplatelet therapy (DAT) discontinuation, reflecting lack of pertinent long-term data. This ...

The treatment paradigm for patients with an ST-elevation myocardial infarction (STEMI) has shifted greatly in the last 20 years. The use of fibrinolytic agents vastly altered the landscape in treating this entity and was further advanced by the introduction of percutaneous catheter-based methods of therapy. Percutaneous coronary intervention (PCI) has ...

Carotid stenosis is often present in patients who need cardiac surgery and is predictive of post-operative stroke. A strategy of combined carotid endarterectomy and cardiac surgery had been adopted in the past. Staged carotid artery stenting prior to cardiac surgery is a less invasive alternative and seems to be associated ...

Polymer-coated drug-eluting stents are effective in preventing restenosis but have been associated with delayed healing and incomplete strut coverage. It is unknown whether paclitaxel-eluting stents (PES) with minimal biodegradable abluminal coating enhances strut coverage while preventing neointimal hyperplasia. Using optical coherence tomography (OCT) as a primary imaging modality, we assessed ...

The management of antithrombotic therapy in atrial fibrillation patients presenting with acute coronary syndrome and/or undergoing percutaneous coronary inter vention/stenting cannot be done according to a regimented common protocol, and stroke and bleeding risk stratification schema should be employed to individualize treatment options. A delicate balance is needed between the ...

Cobalt chromium stents (CCS) are seldom compared to drug-eluting stents (DES) for coronary intervention in published clinical trials. We evaluated the daily usage patterns of CCS in comparison to DES unconstrained by eligibility criteria. We compared consecutive patients (n = 303) with de novo lesions treated exclusively with a CCS ...

The accurate assessment of a target coronary lesion and appropriate stent selection is important in ensuring procedural success during percutaneous coronary intervention (PCI). Though quantitative coronary angiography (QCA) and intravascular ultrasound (IVUS) are available, stent selection is most commonly performed by visual estimation alone. Computed tomographic coronary angiography (CTA) has ...

Dextrocardia is a rare congenital anomaly with a prevalence of 1 in 10,000 births. The incidence of coronary artery disease in such patients is thought to be similar to that of the general public, however, patients are seldom seen during routine clinical practice and at the cardiac catheterization laboratory. Patients ...

Coronary late stent thrombosis, a rare but devastating complication, remains an important concern in particular with the increasing use of drug-eluting stents. Notably, pathological studies have indicated that the proportion of uncovered coronary stent struts represents the best morphometric predictor of late stent thrombosis. Intracoronary optical frequency domain imaging (OFDI), ...
Martuscelli Eugenio - - 2010
BACKGROUND: Imaging artifacts due to metallic stent struts can reduce the diagnostic accuracy of multislice computed tomography (MSCT) in the evaluation of in-stent restenosis (ISR). Our aim was to determine the accuracy of binary ISR exclusion using a 64-slice MSCT scanner and a systematic administration of beta-blockers having an aggressive ...
