Right ventricular function and iron deficiency in acute heart failure
2021
Abstract Aims Iron deficiency (ID) is a frequent finding in patients with chronic and acute heart failure (AHF) along the full spectrum of left ventricular ejection fraction (LVEF). Iron deficiency has been related to ventricular systolic dysfunction, but its role in right ventricular function has not been evaluated. We sought to evaluate whether ID identifies patients with greater right ventricular dysfunction in the setting of AHF. Methods and results We prospectively included 903 patients admitted with AHF. Right systolic function was evaluated by tricuspid annular plane systolic excursion (TAPSE) and the ratio TAPSE/pulmonary artery systolic pressure (TAPSE/PASP). Iron deficiency was de…
<title>Near-infrared spectroscopy (NIRS) as a diagnostic tool in patients with suspected stroke or traumatic brain injury</title>
2001
Near-Infrared Spectroscopy (NIRS) as a diagnostic tool in patients with suspected stroke or brain injury S. Goldberg, C. Lott, M. Ostermeyer, H.-J. Hennes Absorption of Near-Infrared (NIR) light in the brain is mainly caused by hemoglobin. Superficial intracranial hematoma with a higher concentration of hemoglobin causes a higher absorption in NIRS. The existence of hemorrhage can be demonstrated by the difference of optical density, comparing identical measuring points at both hemispheres of the brain: absorption of NIR light is greater at the side of the hemorrhage, causing less reflection in NIRS. In a prospective, blinded study, 100 patients who were scheduled for CCT-scan for brain inj…
Transfemoral Transcatheter Tricuspid Valve Replacement With the EVOQUE System
2021
Abstract Objectives The purpose of this observational first-in-human experience was to investigate the feasibility and safety of the EVOQUE tricuspid valve replacement system and its impact on short-term clinical outcomes. Background Transcatheter tricuspid intervention is a promising option for selected patients with severe tricuspid regurgitation (TR). Although transcatheter leaflet repair is an option for some, transcatheter tricuspid valve replacement (TTVR) may be applicable to a broader population. Methods Twenty-five patients with severe TR underwent EVOQUE TTVR in a compassionate-use experience. The primary outcome was technical success, with NYHA (NYHA) functional class, TR grade, …
Outcomes of transcatheter tricuspid valve intervention by right ventricular function: a multicentre propensity-matched analysis
2021
BACKGROUND Tricuspid regurgitation (TR) has a poor prognosis and limited treatment options and is frequently accompanied by right ventricular (RV) dysfunction. Transcatheter tricuspid valve interventions (TTVI) to reduce TR have been shown to be safe and feasible with encouraging early results. Patient selection for TTVI remains challenging, with the role of right ventricular (RV) function being unknown. AIMS The aims of this study were 1) to investigate survival in a TTVI-treated patient population and a conservatively treated TR population, and 2) to evaluate the outcome of TTVI as compared to conservative treatment stratified according to the degree of RV function. METHODS We studied 684…
Determinants of elevated carbohydrate antigen 125 in patients with severe symptomatic aortic valve stenosis referred for transcatheter aortic valve i…
2018
Elevated carbohydrate antigen 125 (CA125) predicts adverse outcome after transcatheter aortic valve implantation (TAVI). While known underlying pathophysiological mechanisms of elevated CA125 include serosal effusions and inflammatory stimuli, clinical determinants associated with elevated CA125 in patients referred for TAVI remain unknown. Therefore, we investigated clinical, laboratory and echocardiographic determinants of elevated CA125 in patients with severe aortic valve stenosis referred for TAVI.This study includes 650 patients with severe aortic stenosis referred for TAVI. Baseline CA125 was determined by an immunoassay and dichotomized (elevated versus normal) based on the manufact…
Giant right atrial myxoma: A rare cause of cardiovascular collapse
2019
We report the case of a patient with a giant right atrial myxoma that remained clinically silent until it almost completely obliterated the right atrium, prolapsed into the right ventricle and obstructed the tricuspid valve inflow. This case illustrates the importance of rapid surgical intervention in the setting of acute heart failure caused by tumor masses obliterating heart valves or cardiac chambers.
Transesophageal contrast echocardiography is not always the gold standard method in the identification of a patent foramen ovale: A clinical case
2015
In the embryo, Eustachian valve is a crescent-shaped membrane extending from the lower margin of the inferior vena cava and the ostium of the coronary sinus into the right atrium toward fossa ovalis and tricuspid valve. At birth, after the functional closure of the foramen ovale, the Eustachian valve loses its function, reducing to an embryo remnant. According to growing evidence, a persistent Eustachian valve is a frequent finding in patients with a patent foramen ovale (PFO). By directing the blood from the inferior cava to the interatrial septum, it may prevent the spontaneous closure of PFO after birth and indirectly predispose to paradoxical embolism. Transesophageal contrast enhanced …
”Mä kertakaikkiaan löydän jonkun konstin, että nousen täältä” - Kroonista väsymysoireyhtymää (ME/CFS) sairastavien toimijuuden modaliteetit
2022
Krooninen väsymysoireyhtymä (ME/CFS [myalgic encephalomyelitis/ chronic fatigue syndrome]; G93.3) on pitkäkestoinen, harvinainen ja vaikeasti diagnosoitava sairaus, jolle on tyypillistä voimakas pitkäaikainen väsymys, joka ei selity millään muulla fyysisellä tai psykiatrisella sairaudella. Valtakunnalliset Hyvä käytäntö konsensussuositukset sairauden hoitoon julkaistiin helmikuussa 2021. Tässä tutkimuksessa tarkastellaan viiden kroonista väsymysoireyhtymää sairastavan toimijuuden kokemuksia. Erityisenä tarkastelun kohteena ovat terveydenhuollon palvelu- ja hoitojärjestelmän vaikutukset sairastuneiden toimijuuteen. Aineisto on kerätty ennen konsensussuositusten julkaisemista. Tutkimus on la…
Kuulluksi tuleminen on oppimismotivaation avain
2022
Jo pienillä lapsilla on tarve kokea autonomiaa. He haluavat olla aloitteellisia ja itsenäisiä sekä kokea ohjaavansa elämäänsä. Voidakseen kiinnostua koulutyöstä, lapsi tai nuori tarvitsee kokemuksen, että hän tulee kuulluksi, kirjoittaa Kati Vasalampi Jyväskylän yliopistosta. nonPeerReviewed
