AIMS: Initial studies of catheter-based renal arterial sympathetic denervation to lower blood pressure in resistant hypertensive patients renewed interest in the sympathetic nervous system's role in the pathogenesis of hypertension. However, the SYMPLICITY HTN-3 study failed to meet its prespecified blood pressure lowering efficacy endpoint. To date, only a limited number of studies have described the microanatomy of renal nerves, of which, only two involve humans. METHODS AND RESULTS: Renal arteries were harvested from 15 cadavers from the Klinikum Osnabruck and Schuchtermann Klinik, Bad Rothenfelde...

BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is utilized for dysfunctional right ventricular outflow tracts (RVOT) to relieve obstruction, regurgitation, and RV dysfunction. PPVI has not been reported to induce arrhythmias. This study is the first to report the incidence of ventricular tachycardia (VT) after PPVI. METHODS: This was a retrospective study of all patients who had PPVI at a single institution. All patients were admitted after PPVI for overnight telemetry monitoring...

AIMS: Limited data exist on radial access in carotid artery stenting (CAS). This single-center study was performed to compare the outcome and complication rates of transradial (TR) and transfemoral (TF) CAS. METHODS AND RESULTS: The clinical and angiographic data of 775 consecutive patients with high risk for carotid endarterectomy, treated between 1999 and 2016 by CAS with cerebral protection, were evaluated. Patients were divided into 2 groups according to vascular access: TR (n = 101; 13%) and TF (n = 674)...

INTRODUCTION: Stent delivery failure may occur especially when treating complex coronary artery stenosis. XLIMUS (CARDIONOVUM GmbH, Bonn, Germany) is a new sirolimus-eluting stent (SES) with the following features: 1) cobalt chromium stent platform, with low (73 μm) strut thickness, (2) biodegradable polymer, and 3) potent antiproliferative drug (Sirolimus). Preliminary data suggest that XLIMUS SES may be ideal for the treatment of complex lesions. METHODS: In this registry, we assessed the deliverability, safety, and efficacy of percutaneous coronary interventions (PCI) using the XLIMUS SES in patients undergoing elective PCI in native coronary vessels for complex de novo lesions, including severe calcification, severe tortuosity, and chronic total occlusion...

AIMS: This study set out to assess indications, feasibility, complications, and clinical outcome of percutaneous transcatheter device closure of atrial septal defects (ASDs) in infants with a bodyweight below 10 kg. METHODS AND RESULTS: Retrospective single center chart and echocardiography review study from 8/2005-12/2013. Twenty-eight children with ASD (13 female) with a median age of 1.15 years (0.2-2.8) and a median weight of 7.2 kg (4.5-9.9) were analyzed...

OBJECTIVES: Investigate the effectiveness of alcohol septal ablation (ASA) and transaortic extended myectomy (TEM) in hypertrophic cardiomyopathy (HCM) with midventricular obstruction (MVO). BACKGROUND: MVO is less common than subaortic obstruction. Data on the effectiveness of ASA and TEM in MVO are lacking. METHODS: The clinical profiles of 22 patients undergoing ASA and 37 patients undergoing TEM were compared. No patient had apical aneurysm, abnormal chordae, mitral valve replacement or repair...

BACKGROUND: Percutaneous balloon aortic valvuloplasty (PBAV) is a palliative therapeutic option for relief of severe aortic stenosis (AS) in patients that are poor surgical or transcatheter aortic valve replacement (TAVR) candidates or as a bridge to definitive therapy. The outcomes following PBAV are highly variable and studies identifying factors that correlate with outcomes are sparse. The purpose of this study was to identify predictors at the time of the index procedures that can predict 1-year survival or need for repeat PBAV...

OBJECTIVES: This study sought to assess the learning curve for TMVR for treatment of primary mitral regurgitation (MR). BACKGROUND: Data are lacking regarding the technical experience required to achieve optimal clinical outcomes with transcatheter mitral valve repair (TMVR) using the edge-to-edge MitraClip technique. METHODS: We examined the sequential experience of the first 75 patients (age 80 ± 9 years; 77% male) who underwent TMVR at our institution...

BACKGROUND: Drug-coated balloons (DCB) have been used to treat de novo small vessel coronary disease (SVD), with promising results and shorter dual antiplatelet therapy (DAPT) duration compared to drug-eluting stents (DES). We compared safety and effectiveness of the two treatments at 1 year. METHODS: We reviewed 3,613 angioplasty cases retrospectively from 2011 to 2013 and identified 335 patients with SVD treated with device diameter of ≤2.5 mm. DCB-only angioplasty was performed in 172 patients, whereas 163 patients were treated with second-generation DES...

OBJECTIVE: Evaluate the use of mechanical circulatory support (MCS) devices in high-risk patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: The use of MCS devices in elderly patients with multiple comorbidities undergoing TAVR is underexplored. METHODS: All patients undergoing TAVR at a single tertiary academic center who required MCS during index procedure between 2008 and 2015 were included in a prospective database...

BACKGROUND: Septal ablation (SA) is a key modality for left ventricular outflow tract gradient reduction in hypertrophic obstructive cardiomyopathy (HOCM) patients with refractory symptoms. The primary objective of our study was to evaluate post-procedural mortality, complications, length of stay (LOS), and cost of hospitalization following SA. METHODS: We queried the Nationwide Inpatient Sample (NIS) between 2005 and 2011 using the ICD9 procedure code of 37.34 for ablation of heart tissue...

BACKGROUND: Drug-eluting balloons (DEBs) have emerged as a potential alternative to current treatments of instent restenosis (ISR). The study aims to investigate the clinical outcomes of a DEB angioplasty to treat bare-metal stent (BMS) ISR and drug-eluting stent (DES) ISR at 1-year clinical follow-up period. METHODS: Between November 2011 and December 2014, 312 patients were diagnosed with coronary artery ISR at our hospital. A total of 426 coronary ISR lesions were treated with DEBs...

BACKGROUNDS: Long-term fate of patients submitted to patent foramen ovale (PFO) closure is still unclear. The aim of the study was to evaluate the incidence of atrial fibrillation (AF), aortic or atrial free wall erosion, device thrombosis (DT), new onset or worsening of mitral valve regurgitation (MVR), and recurrent cerebral ischemic events in the long-term follow up after intracardiac echocardiography (ICE)-aided PFO closure in a large population. METHODS: We reviewed the medical and instrumental data of 1,000 consecutive patients (mean age 47...

Drug eluting metallic stents have been the "gold standard" in the percutaneous management of coronary artery disease. Recent publications have suggested that the ABSORBTM bioresorbable vascular scaffold (BVS) may represent a reasonable alternative, in well selected cases.

The Portico system (St. Jude Medical, Minneapolis, MN, USA) consists of a self-expanding valve prosthesis and a delivery system designed for transcatheter aortic valve replacement (TAVR). We describe this system, its 10-steps implantation procedure, and provide tips and tricks based on our personal experience with this system.

OBJECTIVES: We evaluated the angiographic and clinical outcomes of orbital atherectomy to treat severely calcified coronary lesions in diabetic and non-diabetic patients. BACKGROUND: Diabetics have increased risk for death, myocardial infarction, and target vessel revascularization after percutaneous coronary intervention. Severely calcified coronary lesions are associated with increased cardiac events. Orbital atherectomy facilitates stent delivery and optimizes stent expansion by modifying severely calcified plaque...
