BACKGROUND: Regional oximetry is increasingly used to monitor post-extraction oxygen status of the brain during surgical procedures where hemodynamic fluctuations are expected. Particularly in cardiac surgery, clinicians employ an interventional algorithm to restore baseline regional oxygen saturation (rSO2) when a patient reaches a critical desaturation threshold. Evidence suggests that monitoring cardiac surgery patients and intervening to maintain rSO2 can improve postoperative outcomes; however, evidence generated with one manufacturer's device may not be applicable to others...

OBJECTIVES: To evaluate the feasibility of coronary procedures after transcatheter aortic valve implantation (TAVI) with the CoreValve™ device. BACKGROUND: Due to its design, CoreValve™ prosthesis may interfere with coronary procedures. Data on this issue are sparse. METHODS: Between 2007 and 2015, 550 patients underwent CoreValve™ TAVI in our hospital. Among them, 16 underwent coronary angiogram after TAVI and were included in our retrospective study...

PURPOSE: Long-term occlusion of coiled aneurysms frequently fails, probably because of poor intrasaccular healing and inadequate endothelialization across the aneurysm neck. The purpose of this study was to determine if attachment of autologous mesenchymal stem cells (MSCs) to platinum coils would improve the healing response in an elastase-induced aneurysm model in rabbits. MATERIALS AND METHODS: With approval from the institutional animal care and use committee, aneurysms were created in rabbits and embolized with control platinum coils (Axium; Medtronic) (n=6) or coils seeded ex vivo with autologous adipose-tissue MSCs (n=7)...

OBJECTIVE: Endovascular aneurysm repair (EVAR) has progressively expanded to treat more challenging anatomies. Although EVAR in patients with wide infrarenal necks has been reported with acceptable results, there is still controversy regarding the longer-term outcomes. Our aim is to determine the impact of infrarenal neck diameter on midterm outcome following EVAR with a single endograft with suprarenal fixation. METHODS: A retrospective case-control study was designed using data from a prospective multicenter database...

AIMS: Data on procedural and clinical outcomes after transcatheter aortic valve implantation (TAVI) with the new generation self-expanding Medtronic Evolut-R prosthesis in comparison with its predecessor, the Medtronic CoreValve, are scarce. METHODS AND RESULTS: In a nationwide, prospective, multi-center cohort study outcomes of consecutive transfemoral TAVI patients treated with the new- generation Medtronic Evolut-R (September 2014 - February 2016) and the Medtronic CoreValve (February 2011 - February 2016) were investigated...

OBJECTIVES: This study sought to describe the results of transcatheter tricuspid valve-in-ring (TVIR) implantation for treatment of tricuspid regurgitation (TR). BACKGROUND: Off-label use of transcatheter valves within surgically placed tricuspid annuloplasty prostheses has only been described in small reports. An international multicenter registry was developed to collect data on TVIR implantation. METHODS: Data were collected from 13 sites on 22 patients (5 to 69 years of age) with TR who underwent catheterization with the intent to perform TVIR implantation...

Regional cerebral oximetry using near-infrared spectroscopy device, an INVOS 5100 C (Medtronic, Minneapolis, MN, USA), during cardiac surgery aims to avoid perioperative neurological impairment, especially during cardiopulmonary bypass. However, it is not uncommon to encounter critically low initial cerebral regional oxygen saturation or a low value unresponsive to intervention. Therefore, it is important to identify factors associated with low saturation value other than true cerebral hypoxia. We investigated the relationship between preoperative regional cerebral oxygen saturation and clinical variables during cardiac surgery...

Interest in minimally invasive video-assisted mitral valve surgery (MIMVS) is rapidly growing. Data on concomitant atrial fibrillation (AF) ablation to MIMVS are still lacking. The present study investigates the long-term results of AF cryoablation concomitant to MIMVS. From October 2006-September 2014, 68 patients with mitral valve disease (age 65.9 ± 11.1 years, 34 men out of 68 patients, Euroscore log 5.4 ± 4.5) and drug-resistant AF underwent MIMVS via right minithoracotomy and concomitant left-sided AF endocardial cryoablation (Cryoflex Medtronic, Minneapolis, MN)...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

INTRODUCTION AND OBJECTIVES: There are scarce clinical outcomes data on the new generation recapturable and repositionable CoreValve Evolut R. METHODS: Data on all-comer patients undergoing transcatheter aortic valve implantation (TAVI) with the Evolut R for severe symptomatic aortic stenosis at a single center were prospectively collected between February 2015 and April 2016. Clinical endpoints were independently adjudicated according to the Valve Academic Research Consortium-2 criteria...

BACKGROUND: First-generation drug-eluting stents (DES) have reduced short-term stent failure as compared to bare-metal stents due to the inhibition of neointima hyperplasia, but instead increased the risk of very-late stent failure. Although better outcomes have been reported for second-generation DES than for first-generation DES, the difference in the angioscopic findings at 1-year follow-up has not been adequately elucidated among second-generation DES. METHODS: Consecutive 161 patients who received angioscopic examination at 1 year after implantation of second-generation DES, i...

New generation of the most widely used devices for transcatheter aortic valve implantation have been recently introduced into practice. We compare the short-term outcomes of transcatheter aortic valve implantation with the Edwards SAPIEN S3 and the Medtronic Evolut-R. We performed a retrospective analysis from a single high-volume tertiary center. Valve Academic Research Consortium-2 criteria were used to define composite end points of device success and safety at 30 days. Study population included 232 patients implanted with the SAPIEN S3 (n = 124) and Evolut-R (n = 108)...

This study presents the in vitro hydrodynamic assessment of the TRISKELE, a new system suitable for transcatheter aortic valve implantation (TAVI), aiming to mitigate the procedural challenges experienced with current technologies. The TRISKELE valve comprises three polymeric leaflet and an adaptive sealing cuff, supported by a novel fully retrievable self-expanding nitinol wire frame. Valve prototypes were manufactured in three sizes of 23, 26, and 29 mm by automated dip-coating of a biostable polymer, and tested in a hydrodynamic bench setup in mock aortic roots of 21, 23, 25, and 27 mm annulus, and compared to two reference valves suitable for equivalent implantation ranges: Edwards SAPIEN XT and Medtronic CoreValve...

Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk. The rapid technologic advances and the recent improvement of clinical outcomes with TAVI have made it possible to treat degenerated bioprosthesis using the valve-in-valve implantation concept (Walther T, Simon P, Dewey T, et al. Transapical minimally invasive aortic valve implantation: multicenter experience...

Motor evoked potentials (MEPs) are commonly used to prevent neurological injury when operating in close proximity to the motor cortex or corticospinal pathway. We report a novel application of the NIM® nerve monitoring system (Medtronic@ NIM response 3.0) for intraoperative direct cortical (dc)-MEPs monitoring. A 69-year-old female patient presented with a 4month history of progressive left hemiparesis resulting from a large right sided posterior frontal meningioma that abutted and compressed the motor cortex...
