BACKGROUND: The gold standard for the follow-up of left atrial appendage occlusion (LAAO) is performing transesophageal echocardiogram (TEE) at 45 days after LAAO; however, the duration for complete LAA seal-off after percutaneous LAAO is unknown in humans. We retrospectively evaluated the LAA contrast-filling (CF) rate in follow-up cardiac computed tomography (CT) scans after LAAO. METHODS: We included 35 patients (age 67.5±10.9 years, CHA2DS2VASc 4.2±1.6, HAS-BLED 3...

A 6-month old female alpaca cria presented to The Ohio State University for evaluation of a cardiac murmur. Echocardiography revealed a left-to-right shunting patent ductus arteriosus, a restrictive left-to-right shunting perimembranous ventricular septal defect, and secondary moderate left atrial and ventricular dilation. Aortic root angiography demonstrated a type IIA patent ductus arteriosus (PDA). Interventional closure of the PDA was successfully performed, without complication, using an Amplatz canine duct occluder...

Repeat cardiac surgery in patients with a previous sternotomy is associated with significant morbidity and mortality. While transcatheter aortic valve implantation in high risk surgical patients is now well established, experience with transcatheter mitral valve replacement is still at an early stage. Although many successful reports of transcatheter mitral valve replacements now exist, the predominant approach has been via a transapical approach. It is likely that, as with the evolution of favoured access routes for transcatheter aortic therapies, future directions for transcatheter mitral valves will focus on smaller delivery systems favouring the transvenous transseptal approach where possible...

BACKGROUND: Little is known regarding intergenerational differences in the effects of atrial sepal defect (ASD) closure on the left heart. We therefore analyzed age-related serial changes in the left heart following ASD closure. METHODS: We studied 50 patients with an isolated ASD who underwent successful transcatheter closure using Amplatzer septal occluders (St. Jude Medical, Little Canada, MN, USA) between June 2007 and June 2013. Patients were divided into three age groups: young patients aged ≤17 years; middle-aged patients aged 18-50 years; and older patients aged >50 years...

AIMS: Trans-esophageal echocardiography (TEE) and MDCT currently serve as imaging modalities for left atrial appendage (LAA) occlusion pre-procedural planning. We assessed the feasibility of multi-detector CT (MDCT) based models to predict the correct size of device for LAA occlusion procedures. METHODS AND RESULTS: Patients planned for LAA occlusion underwent MDCT before implantation, which was used for creating and printing 3D LAA models. Three cardiologists evaluated the 3D models and predicted the correct size of the device by manual manipulation, these predictions were compared with the actual device implanted during the procedure...

Catheter closure of membranous ventricular septal defects is generally not considered feasible in small infants. We report the successful closure of a membranous ventricular septal defect in a 1.8-kg infant with bilateral femoral artery occlusion using Amplatzer Duct Occluder II additional size device. The ventricular septal defect was crossed from the right ventricle, and the device was deployed using transthoracic echocardiographic guidance.

Type II Abernethy malformations, characterized by side-to-side portosystemic shunting with preserved intrahepatic portal venous system, have been treated with shunt closure surgically and endovascularly. Three-dimensional printing has been used to develop highly accurate patient-specific representations for surgical and endovascular planning and intervention. This innovation describes three-dimensional printing to successfully close a flush-oriented type II Abernethy malformation, with discrepant dimensions on computed tomography, conventional venography, and intravascular ultrasound, using a 12-mm AMPLATZER atrial septal occluder device...

PURPOSE: To present an easy and quick technique for embolization of the inferior mesenteric artery (IMA) during endovascular aneurysm repair (EVAR). TECHNIQUE: We performed IMA embolization using a conventional EVAR device alone with the femoral artery approach during EVAR, which has not been reported previously. First, a 16F or 18F DrySeal Sheath is inserted from the femoral artery into the site around the IMA. Second, cannulation is performed in the IMA with an angiography catheter having a 0...

The recommendations for antithrombotic treatment after left atrial appendage closure (LAAC) remain empirical, and no data exist on the changes in hemostatic markers associated with LACC. The objective of the present study is to determine the presence, degree, and timing of changes in the markers of platelet and coagulation activation after LAAC. Forty-three patients (mean age 76 ± 9 years, 23 men) with atrial fibrillation who underwent successful LACC with the Watchman (n = 27) or Amplatzer Cardiac Plug (n = 16) devices were included in the study...

Pulmonary arteriovenous malformation is a rare condition with abnormal communication of the pulmonary artery with the pulmonary vein. It is associated with significant morbidity and mortality when patients develop complications. Patients with symptomatic pulmonary arteriovenous malformation should be considered for intervention. We describe the case of a 54-year-old woman with a large right pulmonary arteriovenous malformation who presented with right chest pain due to hemothorax. She underwent successful embolotherapy with an Amplatzer plug...

A 73-year-old male with no history of liver disease was hospitalized for weakness, confusion, ataxia, and new onset hepatic encephalopathy with hyperammonemia. After management with lactulose and rifaximin, his symptoms persisted, and he underwent transjugular liver biopsy. Biopsy showed normal liver, but a portosystemic shunt was incidentally identified on postbiopsy venogram. The patient underwent occlusion of the shunt with two Amplatzer vascular plugs and four Nester coils. Following embolization, the patient's symptoms resolved completely...

OBJECTIVES: The advent of Amplatzer Duct Occluder II additional Size (ADOIIAS) provided the potential to close hemodynamic significant patent ductus arteriosus (HSPDA) and to analyze the feasibility, safety and efficacy of the device. BACKGROUND: Treatment of a patent ductus arteriosus (PDA) in very premature neonates is still a dilemma for the neonatalogist who has to consider its significance and has to choose among different treatment options. Because surgical ligation and medical therapy both have their drawbacks, interventional catheterization might provide an alternative means of closing HSPDA...

Complications after percutaneous atrial septal defect closure such as residual shunting or device-related events are generally treated using conventional sternotomy or thoracotomy incisions. In these cases, minimally invasive approaches including mini-sternotomy, mini-thoracotomy or endoscopic techniques can also be used in the management of complications, residual defects and concomitant procedures. However, robotic surgery is a reasonable alternative for removal of septal occluder devices and concomitant repair procedures to prevent cardiopulmonary morbidities...

Background: A rare percutaneous nephrolithotomy (PCNL) complication and its management is reported. Case Presentation: A male patient, 43 years of age, underwent PCNL for a large left pyelocaliceal stone. Surgery was performed in the Valdivia-Galdakao supine position. The percutaneous tract was established by combined radiologic and sonographic guidance. The tract was dilated by balloon and a 24F Amplatz sheath was located. As complete clearance was not achieved because of a residual lower pole caliceal stone, a ureteral Double-J and a 20F nephrostomy were located for a second-look PCNL through the same tract after 7 days...

INTRODUCTION: Miniaturization of instruments has changed the paradigms of percutaneous nephrolithotomy (PCNL). To date, however, few studies have analyzed the possible renal trauma generated by PCNL tract dilation. The purpose of this study is to evaluate and compare systematically the renal injury of all PNCL dilation techniques in pork kidneys (PK) and cadaveric kidney models (CK). MATERIAL AND METHODS: Twelve dilation devices were tested (from 4.8 to 30 French (Fr)) including micro- and mini- PCNL kits, the Alken dilation set, 20 and 30 ATM balloons and the Amplatz set...
