STUDY OBJECTIVE: We seek to determine the effect of intraosseous over intravenous vascular access on outcomes after out-of-hospital cardiac arrest. METHODS: This secondary analysis of the Resuscitation Outcomes Consortium Prehospital Resuscitation Using an Impedance Valve and Early Versus Delayed (PRIMED) study included adult patients with nontraumatic out-of-hospital cardiac arrests treated during 2007 to 2009, excluding those with any unsuccessful attempt or more than one access site...

Mitral annular calcification (MAC) is a common condition of the mitral valve apparatus. A case involving caseous calcification, a rare variant of MAC is presented. This variant which has a benign course can present as an intracardiac mass and needs to be differentiated from more sinister causes of calcified cardiac masses such as tumor, abscess, and infective vegetation. Often, this requires multimodality imaging with echocardiography, computed tomography, and magnetic resonance imaging. Features of caseous calcification of the mitral valve on these imaging modalities are reviewed as the associations and clinical features...

Background: Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. Material and Methods: A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups)...

We report the case of a 53-year-old male presenting with a superior vena cava syndrome secondary to a giant intracardiac mass occupying the majority of the right cavities of the heart. A mass of 10.5 cm x 9.5 cm x 4.0 cm originating from the superior vena cava and occupying most of the right atrium, extending through the tricuspid valve into the right ventricle. The mass was resected and the patient was discharged on postoperative day eleven. Pathology report revealed the mass to be a smooth-muscle cell tumor of unknown malignant potential (STUMP)...

Objective: To compare the early clinical effect of septal myectomy and percutaneous transluminal septal myocardial ablation (PTMSA) on the left ventricular outflow obstruction and the rate of complication in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 204 patients with HOCM who received septal reduction treatment were recruited. These patients were divided into two groups, surgery group (n=135) (65 patients with modified Morrow procedure, 70 patients with non-Morrow myomectomy) and PTMSA group (n=69)...

Catheter ablation of atrial fibrillation (AF) is a current therapeutic option but its efficacy for the treatment of long-lasting persistent AF (l-lpAF) remains suboptimal. We tested the laser method as an alternative for catheter ablation of l-lpAF by using an open-irrigated electrode laser mapping and ablation (ELMA) catheter. Laser ablation was attempted in 48 patients aged 50-81 years (69 ± 7.6 y, female = 28) with drug resistant (3.5 trials) l-lpAF (≥12 months). All of the patients had comorbidities: congestive heart failure NYHA II-III (100%), hypertension 29 (60%), coronary artery disease 19 (40%), and heart valve defect 17 (35%)...

We report a case of infective endocarditis on a Perceval S aortic valve bioprosthesis, and we describe a feasible and useful technique that can help remove the infected valve. These maneuvers consist of an "x-movement" reached with the aid of anatomical forceps. The risk of infective endocarditis in patients with prosthetic valves is a well-known phenomena in cardiac surgery, and it can represent a life-threatening event in many cases. According to guidelines, an emergency surgical intervention is required in case of high risk of embolization, vegetation superior than 1 cm or acute cardiac failure secondary to the acute valve dysfunction...

OBJECTIVES: Biological age (BA) has been proposed to evaluate the aging status in an objective way instead of chronological age (CA). The purpose of our study is to construct a more precise formula of BA in the cross-sectional study based on a largest-ever sample of our studies. This formula aims at better evaluation of body function and exploring the disciplines of aging in different genders and age stages. METHODS: A total of 1,373 healthy Chinese Han (age range, 19-93 years) were recruited from five cities in China, including 581 males and 792 females...

Introduction: Aortic valve replacement (AVR) with a mechanical prosthesis is not free from late complications. Aim: To evaluate the prevalence of subclinical hemolysis after AVR with On-X prostheses and assess its impact on long-term outcomes. Material and methods: The prospective study included 84 consecutive patients aged 58.3 ±10.3 years who underwent AVR. They were retrospectively split into group H (n = 12; 14.3%) with prosthesis-related subclinical hemolysis and a control group (C; n = 72; 85...

Decellularized xenogeneic heart valves (DHVs) are promising products for valve replacement. However, the widespread clinical application of such products is limited due to the risk of immune reaction, progressive degeneration, inflammation, and calcification. Here, we have developed an optimized decellularization protocol for a xenogeneic heart valve. We improved the biological function of DHVs by protein tethering onto DHV and three-dimensional (3D) cell seeding in a bioreactor. Our results showed that heart valves treated with a Triton X-100 (TX-100) and sodium deoxycholate (SDC)-based protocol were completely cell-free, with preserved biochemical and biomechanical properties...

OBJECTIVE: Ischemic stroke risk rises with the increasing cardiovascular risk factors in patients with and without AF. How atrial fibrillation (AF) incrementally contributes to the risk for ischemic stroke with increasing age and multiple cardiovascular risk factors is unclear. Von Willebrand factor (vWF) is a biomarker of endothelial dysfunction. PATIENTS AND METHODS: We suggested that in older patients with high CHA2DS2-VASc Score, the vWF and ADAMTS13 would be comparable between patients with and without AF...

A 53-year-old woman was referred to us for reoperation of aortic root. Twenty-three years ago, she was diagnosed with aortitis and suffered from annuloaortic ectasia, aortic regurgitation, severe stenosis of left carotid and subclavian arteries and occulusion of the main trunk of left coronary artery. The left coronary system was perfused by collateral arteries from right coronary artery. She had undergone original Bentall procedure( Cooley graft 26 mm+SJM valve 25 mm) with coronary artery bypass grafting (CABG)[saphenous vein graft (SVG)-left anterior descending artery (LAD)]...

The design and characterization of a new laser-desorption molecular beam source, tailored for use in x-ray free-electron laser and ultrashort-pulse laser imaging experiments, is presented. It consists of a single mechanical unit containing all source components, including the molecular-beam valve, the sample, and the fiber-coupled desorption laser, which is movable in five axes, as required for experiments at central facilities. Utilizing strong-field ionization, we characterize the produced molecular beam and evaluate the influence of desorption laser pulse energy, relative timing of valve opening and desorption laser, sample bar height, and which part of the molecular packet is probed on the sample properties...

OBJECTIVES: The objective is to compare the short-term (30 days) and late (12 months) vascular adverse events in patients undergoing transfemoral (TF)-transcatheter aortic valve replacement (TAVR) by surgical cut-down (SC) vs. percutaneous (PC) approaches. BACKGROUND: Programs continue to utilize both approaches in TF-TAVR. There are limited data comparing outcomes by SC vs. PC approaches and long-term effects of endovascular intervention facilitated hemostasis on late vascular adverse events...

Methods and results: We investigated the disease in 246 subjects (72 mutated) from four FLNA-MVD families harbouring three different FLNA mutations. Phenotype was characterized by a comprehensive echocardiography focusing on mitral valve apparatus in comparison with control relatives...

BACKGROUND: Pressure and waveform at the catheter tip are continuously monitored during catheterization of pulmonary artery to ensure accurate catheter placement. We present a case in which pulmonary venous blood was unexpectedly collected from the pulmonary artery catheter despite pulmonary artery pressure and waveform detection at the catheter tip, and describe the measures taken to correct the catheter placement.
