Calcified lesions have been known as a cause of stent underexpansion which increases the risk of thrombosis and in-stent restenosis. A dual wire balloon has been introduced to create a focal stress pattern in a localized region of the calcification. We evaluated the combination therapy using a dual wire balloon ...

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 ...

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 ...

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 ...

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 ...

In the past histomonosis was very well controlled with Dimetridazole as a treatment and/or Nifursol as feed additive. In the European Union both products were banned in 1995 and 2003, respectively. This was followed by the re-emergence of the disease in the recent years. In the present case a farm ...

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 ...
