BACKGROUND: Balloon Angioplasty (BA) is effective in relieving neoaorta recoarctation (reCoa) after the Norwood procedure. However, recurrence is not uncommon and risk factors for success and recurrence require further elucidation. We report the results of BA for reCoa following the Norwood procedure. We examine acute results and risk factors associated ...

The majority of cerebral arteriovenous malformations (AVM) detected in the United States are diagnosed unruptured and among those, epileptic seizures constitute the most common clinical presentation in otherwise asymptomatic patients.(1) Recent population-based data suggest the 5-year incidence of first-ever seizures after AVM diagnosis is about 8%, but may increase to ...

Voltage-Guided Cavotricuspid Isthmus Ablation. Introduction: The recently proposed "maximum voltage-guided" (MVG) technique for radiofrequency catheter ablation of atrial flutter targets high-voltage electrograms along cavotricuspid isthmus (CTI) to ablate the functionally important anatomic muscle bundles alone, without drawing a complete anatomic line across the CTI. This innovative approach may shorten ablation ...

Aims: Recent reports have suggested susceptibility of novel thin-strut coronary stents to incur longitudinal stent deformation during or following deployment. This analysis assesses the incidence of longitudinal stent deformation in three stent platforms. Methods and results: Quantitative angiographic analysis (QCA) of 2,403 stents from the PERSEUS Workhorse (WH) and PLATINUM-WH ...

The relative safety of drug-eluting stents and bare-metal stents, especially with respect to stent thrombosis, continues to be debated. In view of the overall low frequency of stent thrombosis, large sample sizes are needed to accurately estimate treatment differences between stents. We compared the risk of thrombosis between bare-metal and ...

Venous obstructive lesions represent a therapeutic challenge. Postthrombotic lesions are the most complex and very prone to rethrombosis. Technical success can be achieved in more than 85% of the cases (100% when recanalization with thrombolysis is not needed) with a low rate of periprocedural complications and no mortality. The overall ...

Stent restenosis remains a common complication of bare-metal stent (BMS) implantation. Even in the drug-eluting stent (DES) era, there remains a significant proportion of patients who may not be eligible for DES due to inability to comply with prolonged dual antiplatelet therapy. We reviewed the validity of empirical evidence that ...

This study evaluated the use of a paclitaxel-eluting balloon (PEB) for treatment of femoropopliteal arterial disease. Conventional balloon angioplasty and stenting in this setting is associated with high restenosis rates within 12 months. Recent data suggest that PEB use may reduce restenosis. Twelve-month outcomes following PEB use with provisional stenting ...

Venovenous extracorporeal membrane oxygenation (VV-ECMO) has been used as a management strategy for neonates with refractory pulmonary failure. However, VV-ECMO has been limited in neonates secondary to cannula design and patient size. Herein, we describe the use of a bicaval dual-lumen catheter for VV-ECMO in neonates. The medical records of ...
