Abstract: The Trellis thrombectomy system (Covidien) has been used successfully to perform isolated pharmacomechanical thrombectomy of both venous and arterial thrombi. The device is designed to provide localized treatment while preventing both systemic spread of the thrombolytic agent and also distal embolization. However, when this device is utilized to remove thrombi at bifurcation lesions, embolization into the contralateral vessel can potentially occur.
Simultaneous Inflation of Two Drug-Eluting Balloons for the Treatment of Coronary Bifurcation Restenosis: A Concept Series

Abstract: Coronary bifurcation restenoses are especially challenging lesions to treat. In this report, four cases are described in which an innovative approach consisting of the simultaneous inflation of two drug-eluting balloons has been successfully applied to treat different kinds of bifurcation restenoses following both provisional and complex stenting strategies. These selected cases illustrate the concept and the advantages of a kissing drug-eluting balloon strategy for the treatment of virtually any kind of bifurcation restenosis.
Flexions of the Popliteal Artery: Technical Considerations of Femoropopliteal Stenting

Abstract: Popliteal artery morphology changes while undergoing knee motion. A main flexion (i.e., the ‘hinge point’) and other flexions (termed ‘accessory flexions’) were described as a result of popliteal artery adaptation to knee flexion. Knee dynamics challenge the outcome of popliteal artery endovascular procedures. Complications such us stent fractures were reported despite rapidly improving technology.
The StentBoost Imaging Enhancement Technique as Guidance for Optimal Deployment of Adjacent-Sequential Stents

Abstract: Implantation of two or more adjacent-sequential stents is frequently required during coronary interventions, especially when treating long lesions. We present two cases illustrating that plain fluoroscopic imaging may be misleading when used for guiding optimal deployment of adjacent-sequential stents, whereas implementation of the StentBoost™ (Philips Medical Systems) fluoroscopic technique, which greatly enhances stent visualization in such procedures, may improve the assessment of stent positioning, preventing overlap failure or excessive overlapping.
Modified Technique of BMV for Severe Submitral Stenosis

ABSTRACT: We present a case where difficulty was encountered during balloon mitral valvotomy (BMV) because of severe submitral stenosis. As the orifice was 0.4 cm2 at submitral level the BMV balloon catheter could not enter the left ventricle. We used a modified technique of liberating the submitral apparatus that facilitated successful BMV.

Percutaneous Closure of Aortocaval Fistula Using the Amplatzer Muscular VSD Occluder

ABSTRACT: Aortocaval fistula is an uncommon but often fatal complication of abdominal aortic aneurysm. Both open and endovascular repair of aortic aneurysm with aortocaval fistulae have been previously reported. We present the case of a patient with persistent aortocaval fistula after endovascular stent graft repair, which is closed using an Amplatzer muscular VSD occluder.
Successful Stent Implantation Guided by Intravascular Ultrasound and a Doppler Guidewire Without Contrast Injection in a Patient with Allergy to Iodinated Contrast Media

ABSTRACT: Presence of allergy to iodinated contrast may prevent percutaneous coronary intervention (PCI) to be performed. We present a 76-year-old male with a history of allergic reaction to iodinated contrast who successfully underwent intravascular ultrasound (IVUS) and a Doppler guidewire-guided PCI. Stent size was determined based on IVUS. After PCI, stent expansion and a lack of edge dissection or incomplete apposition were confirmed by IVUS and a good antegrade coronary flow was confirmed by a Doppler guidewire.

ABSTRACT: Cardiac rupture is a fatal complication of transmural myocardial infarction that is associated with high mortality. We describe the successful management of a case of subacute cardiac rupture and cardiogenic shock supported by a percutaneous left ventricular assist device (LVAD) as a bridge to surgery.
“Sepal Wire Technique” — A Novel Technique for Aorto-ostial Left Main Stenting

ABSTRACT: Aorto-ostial left main (LM) percutaneous coronary intervention (PCI) remains a challenge in interventional cardiology, as precise positioning of stents using conventional angiographic landmarks is difficult. Previously described techniques either involve the use of additional complex steps or commercially available special devices that carry extra costs.

Initial Experience with the Amplatzer Vascular Plug IV in Congenital Heart Disease: Coronary Artery Fistula and Aortopulmonary Collateral Artery Embolization

ABSTRACT: Background. A number of percutaneous devices are available to embolize anomalous vessels in congenital heart disease. We report our initial single-center experience with the new Amplatzer Vascular Plug IV (AVP IV) in congenital heart disease to embolize a coronary artery fistula and aortopulmonary collateral arteries in 4 cases.
