Cardiac biomarker release after exercise is well documented in endurance sports, but neither the impact of intermittent high‐intensity nor reproducibility has yet been established. Floorball, a popular sport S candinavia, involves periods exercise. This study aimed to determine prevalence and elevated cardiac marker levels among elite floorball players two games. Twenty‐three healthy male median age 19 years (range 16–34 years) participated standard Blood was drawn at three time points:...

Differences in adverse cardiac remodeling between patients who have bicuspid (BAV) and tricuspid aortic valve (TAV) with severe isolated stenosis (AS) its prognostic impact after surgical replacement remains unclear. We sought to investigate differences preoperative diastolic systolic function BAV TAV AS the incidence of postoperative heart failure hospitalization mortality.Two hundred seventy-one (n=152) or (n=119) without coronary artery disease other valvular disease, scheduled for...

Abstract Aims To investigate (i) the association between pre-operative left atrial (LA) reservoir strain and post-operative fibrillation (AF) (ii) incidence of ischaemic stroke events separately in bicuspid aortic valve (BAV) tricuspid (TAV) patients after surgical replacement for isolated severe stenosis (AS). Methods results We prospectively enrolled 227 (n = 133 BAV n 94 TAV) with AS scheduled replacement. A comprehensive intra- inter-observer validated echocardiogram an analysis LA was...

Aortic valve degeneration (AVD) is a life-threatening condition that has no medical treatment and lacks individual therapies. Although extensively studied with standard approaches, aetiologies behind AVD are unclear. We compared abundances of extracellular matrix (ECM) proteins from excised tissues 88 patients isolated normal tricuspid (TAV) congenital bicuspid aortic valves (BAV), quantified more than 1400 per ECM sample by mass spectrometry, demonstrated local preserves molecular cues the...

BACKGROUND: This study aimed to compare the incidence and prognostic implications of new-onset conduction disturbances after surgical aortic valve replacement (SAVR) in patients with bicuspid (BAV) stenosis (AS) versus tricuspid (TAV) AS (ie, BAV-AS TAV-AS, respectively). Additionally, included stratification BAV according subtype. METHODS: In this cohort study, postoperative third-degree atrioventricular (AV) block subsequent permanent pacemaker requirement left bundle-branch (LBBB) was...

Severe aortic regurgitation (AR) is an extremely rare complication after coronary catheterization and percutaneous intervention (PCI), where most reported cases have required relatively urgent surgical due to acute-onset AR cardiac decompensation.We report a case of 60-year-old woman that previously presented with non-ST-elevation myocardial infarction (NSTEMI) ostial right artery stenosis. During the course 2 years, she developed five recurrent NSTEMI in-stent thrombosis, necessitating...

Assessment of hematological parameters is common in sports medicine. Although physical exercise an important preanalytical variable, data about acute changes after high-intensity intermittent are scarce. This study aimed to examine floorball as a potential variable for used health assessment and antidoping testing. Twenty-three professional male players participated game. Hematological including hemoglobin, erythrocyte count indices, reticulocytes, white blood cells (WBC), platelets, OFF-hr...

Release of cardiac biomarkers is common after strenuous endurance exercise, but data on intermittent exercise are scarce. It has not been investigated whether troponin elevation influenced depending the type that an athlete adapted to perform. We hypothesized continuous induces in professional athletes high-intensity exercise.

Transcatheter edge-to-edge mitral valve repair (TEER) with a clip device relieves symptoms and improves outcomes in patients not suitable for open heart surgery. Here, we present patient whom ventricular arrhythmias developed as result of embolization shortly after TEER. He underwent successful emergent surgical removal replacement. (Level Difficulty: Advanced.).

•Multimodality imaging plays a crucial role in confirming cardiac echinococcosis.•Speckle-tracking echocardiography gives information about regional myocardial function.•Cyst rupture often causes life-threatening anaphylactic shock.•We present an unusual case of cyst rupture, with chest pain as the only symptom.•Complete surgical removal is treatment choice for echinococcosis.

Primary cardiac tumors are extremely rare, with an incidence, according to autopsy series, of <0.1%.1 About 75% all primary benign. Cardiac myxomas, a neoplasm arising from endocardial mesenchymal stem cells, represent the most common benign tumor in adults.2 myxomas can occur age groups but middle-aged patients,2 female predominance approximately 2:1.3 typically originate interatrial septum, and left atrium is location mass, housing up 80% myxomas.

ABSTRACT The indication for transcatheter aortic valve implantation (TAVI) is continuously expanding with a simultaneous increase in number of TAVI associated prosthetic endocarditis (TAVI–PVE). Evidence management TAVI–PVE lacking but the need surgical complex expected to increase. Commando procedure, technically challenging surgery treatment endocarditis, has never been described patient TAVI–PVE. An 80-year-old female TAVI–PVE, native mitral and an abscess intervalvular fibrous body was...
