Three-dimensional (3D) printing has attracted a huge interest in recent years. Broadly speaking, it refers to the technology which converts a predesigned virtual model to a touchable object. In clinical medicine, it usually converts a series of two-dimensional medical images acquired through computed tomography, magnetic resonance imaging or 3D echocardiography into a physical model. Medical 3D printing consists of three main steps: image acquisition, virtual reconstruction and 3D manufacturing. It is a promising tool for preoperative evaluation, medical device design, hemodynamic simulation and medical education, it is also likely to reduce operative risk and increase operative success...

BACKGROUND: Coronary bifurcation lesions pose therapeutic problems during percutaneous coronary interventions. The aim of this study was to analyze the strategy of coronary bifurcation treatment and associated angiographic as well as clinical outcomes in a large hospital in Northern Poland. METHODS: Between January 2012 and January 2014 patients with stable coronary artery disease or non-ST-elevation acute coronary syndrome (NSTE-ACS) were treated with regular drug-eluting stents (rDES) or dedicated bifurcation stents (BiOSS Expert® or BiOSS LIM®)...

BACKGROUND: Patients with supraventricular tachycardia (SVT) and patients with coronary artery disease (CAD) often present with similar symptoms (chest pain, shortness of breath), similar electrocardiographic changes and elevated high-sensitivity troponin (cTn). It is not clear whether troponin reflects critical CAD or is elevated due to other causes in patients presenting with SVT. The aim of this study was to assess the role of elevated troponin in patients presenting with SVT. METHODS: Patients undergoing radiofrequency ablation (RFA) for SVT and simultaneous coronary angiography at the Heart Centre Lucerne, Switzerland between January 2010 and October 2014 were included in this analysis...

BACKGROUND: Obesity contributes to left ventricular diastolic dysfunction (LVDD) and may lead to diastolic heart failure. Weight loss (WL) after bariatric surgery (BS) may influence LV morphology and function. Using echocardiography, this study assessed the effect of WL on LV diastolic function (LVDF) and LV and left atrium (LA) morphology 6 months after BS in young women with morbid obesity. METHODS: Echocardiography was performed in 60 women with BMI ≥ 40kg/m², aged 37...

Estimation of right ventricular (RV) performance still remains technically challenging due to its anatomical and functional distinctiveness. The current guidelines for the echocardiographic quantification of RV function recommend using multiple indices to describe the RV in a thorough and comprehensive manner, such as RV index of myocardial performance, tricuspid annular plane systolic excursion, fractional area change, Doppler tissue imaging-derived tricuspid lateral annular systolic velocity (S'-wave), three-dimensional RV ejection fraction (3D RVEF), longitudinal strain (RVLS)/strain rate by speckle-tracking echocardiography (STE)...

BACKGROUND: Despite left ventricular (LV) dysfunction contributing to mortality in chronic heart failure (HF), the molecular mechanisms of LV failure continues to remain poorly understood and myocardial biomarkers have yet to be identified. The aim of this pilot study was to investigate specific transcriptome changes occurring in cardiac tissues of patients with HF compared to healthy condition patients to improve diagnosis and possible treatment of affected subjects. METHODS: Unlike other studies, only dilated cardiomyopathy (DCM) (n = 2) and restrictive cardiomyopathy (RCM) (n = 2) patients who did not report family history of the disease were selected with the aim of obtaining a homogeneous population for the study...

BACKGROUND: The ability of optical coherence tomography (OCT) to visualise macrophages in vivo in coronary arteries is still controversial. We hypothesise that imaging of macrophages in OCT could be enhanced by means of superparamagnetic nanoparticles. METHODS: We compared the optical backscattering and attenuation of cell pellets containing RAW 264.7 macrophages with those of macrophagic cell pellets labelled with very small superparamagnetic oxydised nanoparticles (VSOP) by means of light intensity analysis in OCT...

BACKGROUND: Although coronary artery disease and arterial hypertension are the most common etiologies underlying heart failure (HF), there are still many patients present with non-ischemic and non-hypertensive HF whose management remains very challenging. In this research study the clinical profile and applied treatment of patients with HF without coronary artery disease or hypertension versus patients with known etiology of HF (ischemic/hypertensive) were compared. METHODS: Clinical data about 5563 patients with stable systolic HF were obtained from prospective multicenter DATA-HELP registry performed between October and December 2009 in ambulatory clinics in Poland, in which 500 cardiologists and 290 GPs participated...

BACKGROUND: Intravenous hydration during percutaneous coronary intervention (PCI) significantly reduces the risk of contrast-induced nephropathy (CIN), but there are no well-defined protocols regarding the optimal hydration volume (HV) required to prevent CIN following emergent percutaneous coronary intervention (PCI). Therefore, this study investigates the association between the intravenous HV and CIN after emergent PCI. METHODS: 711 patients were prospectively recruited who had underwent emergent PCI with hydration at routine speed and the relationship was investigated between HV or HV to weight ratio (HV/W) and the CIN risk, which was defined as a ≥ 25% or ≥ 0...

BACKGROUND: Lower extremity arterial disease (LEAD) is a well-established risk factor for concomitant coronary artery disease (CAD). There are no published data combining all three lower limb arterial segments (aortoiliac, femoropopliteal and below the knee vessels) in order to estimate CAD severity in LEAD patients. Herein has been derived a new scoring system for this purpose, which uses the well-known TASC II classification, Syntax score and, for the first time in medical literature, a Syntax II score...
