Lapuerta Irigoyen J A, Valverde Andre I, Vigil Escalera P, Gonzalez Vasserot M
Introduction: The AcapConfirm™ feature available with the Zephyr pacemaker family (St. Jude Medical) is designed for monitoring patient's atrial capture threshold periodically, and automatically adjusting the atrial pulse amplitude. Previous studies showed a relative low proportion of patients at three months follow-up with recommended automatic atrial capture after the AcapConfirm™ viability test. The purpose of the present study is to evaluate the effect of inter electrode distance on the viability of the AcapConfirm™ algorithm...

A 40-year-old man with osteogenesis imperfecta type I submitted to multiple procedures of surgical mitral and aortic valve replacement was referred for refractory congestive heart failure due to significant paravalvular leaks (PVLs) of both mitral and aortic prostheses. Due to perceived very high risk of a further mitroaortic surgery, transcatheter closure of PVLs under three-dimensional echocardiographic guide was performed. Thus, four Amplatzer Vascular Plug type II (St. Jude Medical Corp, St. Paul, Minnesota, USA) devices were implanted into the aortic PVLs, and three Amplatzer Vascular Plug type II devices were used to occlude a huge mitral PVL...

REVIEW
Mikhael F El-Chami, Faisal M Merchant, Angel R Leon
Leadless pacing is an emerging technology with the potential to significantly improve outcomes associated with the need for long-term pacing. Specifically, the major advantage of leadless systems is abolishing the need for transvenous leads and subcutaneous pockets, both of which account for most adverse events associated with traditional pacemakers. Two leadless pacemakers are currently available: the Nanostim (leadless cardiac pacemaker [LCP]) device (St. Jude Medical, Sylmar, California) and the Micra Transcatheter pacing system (Medtronic, Minneapolis, Minnesota)...

BACKGROUND: The relative importance of focal drivers, multiple wavelets, rotors and endocardial-epicardial circuits in the maintenance of persistent AF remains unclear. Our objective was to characterize AF wavefront (WF) dynamics during persistent AF. METHODS: The Ensite 3000 (St Jude Medical) non-contact mapping system was used to map the LA of 15 patients with persistent AF. Wavefronts were classified into planar WFs, rotors or focal WFs. For each new WF the site of origin, the unipolar electrogram, and propagation patterns were determined...

Iatrogenic common femoral artery pseudoaneurysm is a well-described vascular access complication. Several methods have been proposed to treat these pseudoaneurysms. In this report, we present three cases of successful pseudoaneurysm closure using a novel method of retrograde pseudoaneurysm access and thrombosis with Angio-Seal (St Jude Medical, St Paul, MN) closure device. This technique appears safe, effective, and reduces patient discomfort.

Left atrial appendage (LAA) dimensions have been shown as an independent predictor of higher risk for stroke in AF patients. Little data exist on the outcomes after LAA closure in patients with nonvalvular atrial fibrillation (NVAF) who have relatively bigger LAA size. This study aims to evaluate the results associated with LAA closure with the Amplatzer cardiac plug (ACP, AGA, St. Jude Medical, Minneapolis, MN) in bigger LAA size. A total of 25 patients with NVAF underwent LAA closure with the ACP device. All patients received short-term (up to 3 months) dual-antiplatelet therapy (clopidogrel and aspirin) after the procedure and aspirin only thereafter...

PURPOSE: Occlusion time (OT) is an important factor in the treatment of pulmonary arteriovenous malformations (PAVMs) since it can lead to serious complications. The purpose of our study is to calculate the OT of Amplatzer vascular plug (AVP, St Jude Medical), and correlate it to the type of the device used (AVP or AVP 2) and the percent of device oversizing. Technical success rates and complications were also recorded. METHODS: We retrospectively studied a total of 19 patients with 47 PAVMs who received percutaneous transcatheter embolization therapy using either AVP or AVP 2...

Neuroma pain can be severe, persistent, and treatment resistant. We present a case of a 37-year-old female amputee who suffered from severe neuroma pain, which had proved resistant to pharmacologic treatment, glycerol injections, spinal cord stimulation, radiofrequency thermocoagulation, and repeated surgical removals. After treatment with peripheral nerve stimulation, using a St. Jude Medical Octrode lead implanted percutaneously under ultrasound guidance close to her painful neuroma, her ongoing pain dramatically decreased from 8 to 3 on a numeric rating scale (0-10)...

BACKGROUND: Percutaneous coronary intervention (PCI) is most commonly guided by angiography alone. Intravascular ultrasound (IVUS) guidance has been shown to reduce major adverse cardiovascular events (MACE) after PCI, principally by resulting in a larger postprocedure lumen than with angiographic guidance. Optical coherence tomography (OCT) provides higher resolution imaging than does IVUS, although findings from some studies suggest that it might lead to smaller luminal diameters after stent implantation...

Characterization and mapping of arrhythmias is currently performed through invasive insertion and manipulation of cardiac catheters. Electromechanical wave imaging (EWI) is a non-invasive ultrasound-based imaging technique, which tracks the electromechanical activation that immediately follows electrical activation. Electrical and electromechanical activations were previously found to be linearly correlated in the left ventricle, but the relationship has not yet been investigated in the three other chambers of the heart...
