BACKGROUND: A number of lipoprotein(a) [Lp(a)] analytical techniques are available that quantify distinct particle components, yet their clinical efficacy has not been comprehensively evaluated. This study determined whether Lp(a) mass [Lp(a)-M], Lp(a) cholesterol content [Lp(a)-C], and particle concentration [Lp(a)-P] differentially discriminated risk of calcific aortic valve disease (CAVD) or incident coronary heart disease (CHD) among 4679 participants of the Multi-Ethnic Study of Atherosclerosis (MESA)...

BACKGROUND: Bidirectional cavopulmonary anastomosis (BCPA) is an important preliminary step toward the Fontan procedure; thus, understanding of risk factors for morbidity and mortality after BCPA may ultimately promote improved rates of success with Fontan completion and general survival. This study evaluated survival and predictors of unfavorable outcomes in patients after BCPA. METHODS: Clinical data of 157 patients who underwent BCPA from 2003 to 2015 at a single center were retrospectively analyzed...

Transcatheter aortic valve implantation (TAVI) has been widely used for the treatment of aortic stenosis. Most pivotal studies of TAVI included patients with a mean age of over 80 years old. Many young patients may also be considered for TAVI because of severe co-morbidities. We sought to describe a group of patients undergoing TAVI at an age below 70 and to compare them with older patients undergoing the procedure. This study included 1,324 consecutive patients from a 3-center TAVI registry from 2008 to 2014...

BACKGROUND: Fast relief of migraine pain, associated symptoms, and migraine-related disability are priorities in the acute treatment of migraine. Efforts to improve the pharmacokinetic profiles of acute migraine treatments with the aim of providing faster relief include the development of non-oral routes of administration. AVP-825 (ONZETRA(®) Xsail(®) ) is a delivery system containing 22 mg sumatriptan powder that uses a patient's own breath to deliver medication intranasally, targeting the upper posterior nasal cavity beyond the narrow nasal valve, an area lined with vascular mucosa conducive to rapid drug absorption into the systemic circulation...

OBJECTIVES: The indication for screening for valvular heart disease in patients taking cabergoline is based on evidence from patients with Parkinson's disease on high-dose medication. However, current patients take much lower doses for indications such as hyperprolactinaemia disorders. Contemporary guidelines for echocardiogram monitoring in patients taking cabergoline are conflicting. This study aimed to review current clinical practice in our area regarding echocardiographic screening and to review the literature examining the evidence of valvular heart disease in patients taking lower dose cabergoline...

Blue whale sound production has been thought to occur by Helmholtz resonance via air flowing from the lungs into the upper respiratory spaces. This implies that the frequency of blue whale vocalizations might be directly proportional to the size of their sound-producing organs. Here we present a sound production mechanism where the fundamental and overtone frequencies of blue whale B calls can be well modeled using a series of short-duration (<1 s) wavelets. We propose that the likely source of these wavelets are pneumatic pulses caused by opening and closing of respiratory valves during air recirculation between the lungs and laryngeal sac...

Periprocedural myocardial infarction (MI), a rare complication after transcatheter aortic valve implantation (TAVI), is associated with worse outcome. According to the Valve Academic Research Consortium (VARC-2), MI is defined by an increase in cardiac troponin (cTn) and creatine kinase MB (CK-MB) levels; however, many patients show periprocedurally elevated cTn without clinical evidence of MI. The aims of this study were to establish reference values of cardiac troponin I measured with a high-sensitivity assay (hs-cTnI) and to assess the periprocedural diagnostic value of this biomarker in patients who underwent TAVI...

BACKGROUND: Left ventricular (LV) filling following atrial contraction generates LV myocardial stretch that propagates from base to apex with a speed proportional to myocardial elasticity. The aim of this study was to test the hypothesis that intrinsic velocity propagation of myocardial stretch (iVP) would be altered in patients with valvular disease and chronic LV pressure overload or volume overload, which may adversely affect mechanical properties of the LV tissue. A second aim was to compare iVP with flow propagation velocity in the chamber...

BACKGROUND: Previous studies suggest a relationship of the epicardial adipose tissue (EAT) with progression and calcification of the atherosclerotic plaque; however, it is unknown if this tissue expresses genes that may participate on these processes and if the expression of these genes is regulated by high-density lipoprotein (HDL) subclasses. METHODS: To explore this possibility, we determined the mRNA expression by qPCR of a pro-calcifying gene (osteopontin (OPN)), and two anti-calcifying genes (osteoprotegerin (OPG) and osteonectin (ON)), in biopsies of EAT obtained from 15 patients with coronary artery disease (CAD) determined by angiography, and 15 patients with diagnostic of aortic valve stenosis but without CAD as control group...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an established treatment option for patients with severe aortic stenosis and high surgical risk. Currently, various prosthesis types are available. Atrioventricular block (AVB) requiring pacemaker (PM) implantation is a typical complication after TAVI. This study investigated the recovery of AV node conduction and mid-term outcome of patients with or without PM implantation after TAVI according to prosthesis type. METHODS: From July 2008 to May 2015, 856 transcatheter heart valves were implanted at our center (age: 80...

Introduction Ventilation with a bag valve mask (BVM) is a challenging but critical skill for airway management in the prehospital setting. Hypothesis Tidal volumes received during single rescuer ventilation with a modified BVM with supplemental external handle will be higher than those delivered using a standard BVM among health care volunteers in a manikin model. METHODS: This study was a randomized crossover trial of adult health care providers performing ventilation on a manikin. Investigators randomized participants to perform single rescuer ventilation, first using either a BVM modified by addition of a supplemental external handle or a standard unmodified BVM (Spur II BVM device; Ambu; Ballerup, Denmark)...

INTRODUCTION: The presence of symptoms, systolic dysfunction and Left Ventricle (LV) dilation are considered unfavourable prognostic markers in Aortic Valve Insufficiency (AVI). The role of diastolic dysfunction, which is considered unfavourable outcome marker in cardiac pathologies, is not well established in AVI. AIM: To evaluate if the presence of diastolic dysfunction may be associated with unfavourable prognostic markers in AVI patients. MATERIALS AND METHODS: A cross-sectional prospective study was performed on 22 patients with moderate or severe AVI...

Aortic stenosis is one of the most frequent valvular diseases in developed countries, and its impact on public health resources and assistance is increasing. A substantial proportion of elderly people with severe aortic stenosis is not eligible to surgery because of the advanced age, frailty, and multiple co-morbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...
