Left main stem disease: percutaneous coronary intervention vs. coronary artery bypass grafting-what about medical management? A case report.

Background: Optimal strategy for treating bifurcation lesions in the left main coronary artery (LMCA) remains elusive.

Case Summary: We describe a 66-year-old Caucasian male with a risk factor for coronary artery disease, but free of angina, who presented to the hospital after syncope and nsVT diagnosis in the 24 h Holter electrocardiography monitoring. Coronary computed tomography angiography revealed LMCA bifurcation stenosis with concomitant left circumflex artery (LCx) and diagonal branch stenosis.

The Advantage of Targeted Next-Generation Sequencing over qPCR in Testing for Druggable Variants in Non-Small-Cell Lung Cancer.

The emergence of targeted therapies in non-small-cell lung cancer (NSCLC), including inhibitors of epidermal growth factor receptor (EGFR) tyrosine kinase, has increased the need for robust companion diagnostic tests. Nowadays, detection of actionable variants in exons 18-21 of the gene by qPCR and direct DNA sequencing is often replaced by next-generation sequencing (NGS). In this study, we evaluated the diagnostic usefulness of targeted NGS for druggable variants testing in clinical NSCLC material previously analyzed by the IVD-certified qPCR test with respect to DNA reference material.

Transcatheter Intervention for Inoperable Tricuspid Surgical Prosthesis Dysfunction: Minimally Invasive Approach to Mitigate Heart Failure.

What is the efficacy and safety of transcatheter tricuspid valve-in-valve implantation for patients with inoperable tricuspid surgical prosthesis dysfunction? Thirty-day mortality after greatly effective transcatheter treatment is 2 times less than the estimated surgical risk.

Tricuspid valve disease and cardiac implantable electronic devices.

The role of cardiac implantable electronic device (CIED)-related tricuspid regurgitation (TR) is increasingly recognized as an independent clinical entity. Hence, interventional TR treatment options continuously evolve, surgical risk assessment and peri-operative care improve the management of CIED-related TR, and the role of lead extraction is of high interest. Furthermore, novel surgical and interventional tricuspid valve treatment options are increasingly applied to patients suffering from TR associated with or related to CIEDs.

Emergency contraception - A review.

Emergency contraception (EC), or postcoital contraception, is a therapy aimed at preventing unintended pregnancy after an act of unprotected or under-protected sexual intercourse. Options include both emergency contraceptive pills (most commonly containing levonorgestrel or ulipristal acetate) and insertion of an intrauterine device. The aim of this paper is to summarize current evidence surrounding the use of emergency contraceptives and to present an evidence-based approach to EC provision.

Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI): Characteristics and early results from a nationwide registry.

Background: Valve-in-valve transcatheter transfemoral mitral valve implantation (ViV-TMVI) is an emerging treatment alternative to reoperation in high-surgical risk patients with failed mitral bioprostheses.

Aim: We aimed to describe the characteristics of ViV-TMVI and evaluate its 30-day outcomes in the Polish population.

Methods: A nationwide registry was initiated to collect data on all patients with failed mitral bioprosthesis undergoing ViV-TMVI in Poland.

The Etiology of Community-Acquired Pneumonia Correlates with Serum Inflammatory Markers in Children.

Community-acquired pneumonia (CAP) severely affects pediatric hospitalizations. This study assessed the contribution of CAP to hospitalizations, its etiology in relationship with age, and the inflammatory markers. Between 2013 and 2018, 1064 CAP patients were hospitalized and diagnosed with bacterial/possibly bacterial pneumonia (BP), viral/possibly viral pneumonia (VP) and atypical pneumonia (AP).

FGFR1-4 RNA-Based Gene Alteration and Expression Analysis in Squamous Non-Small Cell Lung Cancer.

While fibroblast growth factor receptors (FGFRs) are involved in several biological pathways and FGFR inhibitors may be useful in the treatment of squamous non-small cell lung cancer (Sq-NSCLC), FGFR aberrations are not well characterized in Sq-NSCLC. We comprehensively evaluated FGFR expression, fusions, and variants in 40 fresh-frozen primary Sq-NSCLC (stage IA3−IV) samples and tumor-adjacent normal tissues using real-time PCR and next-generation sequencing (NGS). Protein expression of FGFR1−3 and amplification of FGFR1 were also analyzed.

Current Prostheses for Transcatheter Heart Valve Replacement: A Technical and Clinical Review.

Transcatheter aortic valve replacement (TAVR) has become a cornerstone in today's treatment of aortic stenosis. Modern transcatheter prostheses are continuously evolving and each one features different design traits. In this review, the authors provide insight in the technical differences of current prostheses and TAVR related clinical decision pathways, preferably useful for the beginners but also for advanced operators.

Feeding Practices, Maternal and Neonatal Outcomes in Vaginal Birth after Cesarean and Elective Repeat Cesarean Delivery.

Cesarean section rates are constantly rising, and the number of women with a prior cesarean considering a delivery mode for their next labor is increasing. We aimed to compare maternal and neonatal outcomes and feeding method in women undergoing vaginal birth after cesarean (VBAC) versus elective repeat cesarean delivery (ERCD). This was a retrospective cohort study of women with one prior cesarean delivery (CD) and no previous vaginal births, delivering vaginally or by a CD in a single institution between 2016 and 2018.

CT in Transcatheter-delivered Treatment of Valvular Heart Disease.

Minimally invasive strategies to treat valvular heart disease have emerged over the past 2 decades. The use of transcatheter aortic valve replacement in the treatment of severe aortic stenosis, for example, has recently expanded from high- to low-risk patients and became an alternative treatment for those with prohibitive surgical risk. With the increase in transcatheter strategies, multimodality imaging, including echocardiography, CT, fluoroscopy, and cardiac MRI, are used.

Functional CAD-RADS using FFR on therapeutic management and prognosis in patients with coronary artery disease.

Objectives: To propose a novel functional Coronary Artery Disease-Reporting and Data System (CAD-RADS) category system integrated with coronary CT angiography (CCTA)-derived fractional flow reserve (FFR) and to validate its effect on therapeutic decision and prognosis in patients with coronary artery disease (CAD).

Methods: Firstly, we proposed a novel functional CAD-RADS and evaluated the performance of functional CAD-RADS for guiding treatment strategies with actual clinical treatment as a reference standard in a retrospective multicenter cohort with CCTA and invasive FFR performed in all patients (n = 466). Net reclassification improvement (NRI) of functional CAD-RADS over anatomical CAD-RADS was calculated.

Results of expectant management in singleton and twin pregnancies complicated by preterm premature rupture of membranes.

Objectives: This study aimed to examine whether expectant management in twin pregnancies with preterm premature rupture of membranes (pPROM) is as safe as in singleton pregnancies.

Material And Methods: It was a retrospective cohort study comparing pregnancy course and outcome in singleton (n = 299) and twin pregnancies (n = 49) complicated by preterm premature rupture of membranes. Analysed factors included maternal diseases, gestational age at premature rupture of membranes (PROM), management during hospitalization, latency periods between PROM and delivery, gestational age at delivery, neonatal management and outcome.

Efficacy and safety of coronary computed tomography angiography in patients with a high clinical likelihood of obstructive coronary artery disease.

Background: The CAT-CAD trial showed that coronary computed tomography angiography (CTA) in patients with a high prevalence of coronary artery disease (CAD) and indications for invasive coronary angiography (ICA) reduces the number of patients undergoing ICA by two-thirds and nearly eradicates non-actionable ICAs. However, the long-term benefits of this non-invasive strategy remain unknown.

Aims: To evaluate the long-term efficacy and safety of a non-invasive strategy employing coronary CTA vs.

Identifying Patients without a Survival Benefit following Transfemoral and Transapical Transcatheter Aortic Valve Replacement.

Transcatheter aortic valve replacement (TAVR) offers a novel treatment option for patients with severe symptomatic aortic valve stenosis, particularly for patients who are unsuitable candidates for surgical intervention. However, high therapeutical costs, socio-economic considerations, and numerous comorbidities make it necessary to target and allocate available resources efficiently. In the present study, we aimed to identify risk factors associated with futile treatment following transfemoral (TF) and transapical (TA) TAVR.

Detection of EGFR mutations in liquid biopsy samples using allele-specific quantitative PCR: A comparative real-world evaluation of two popular diagnostic systems.

Purpose: The detection of epidermal growth factor receptor (EGFR) mutations in plasma cell-free DNA (cfDNA) is an auxiliary tool for the molecular diagnosis of non-small cell lung cancer (NSCLC), especially when an adequate tumor tissue specimen cannot be obtained. We compared the diagnostic accuracy of two commonly used in vitro diagnostic-certified allele-specific quantitative PCR assays for detecting plasma cfDNA EGFR mutations.

Methods: We analyzed EGFR mutations in plasma cfDNA from 90 NSCLC patients (stages I-IV) before treatment (n ​= ​60) and after clinical progression on EGFR tyrosine kinase inhibitors (n ​= ​30) using the cobas EGFR mutation test v2 (Roche Molecular Systems, Inc.

Complex transcatheter aortic valve replacement in aortic regurgitation and transcatheter mitral annuloplasty in severe dextrocardia.

A 70-year-old female with symptomatic severe native aortic regurgitation, acquired dextrocardia, moderate-to-severe secondary mitral regurgitation and prohibitive surgical risk was admitted for transcatheter aortic valve replacement. A balloon-expendable Sapien 3 Ultra valve was implanted successfully. After 6 months, the patient remained symptomatic due to the concomitant moderate-to-severe secondary mitral regurgitation.

The Iliofemoral tortuosity score predicts access and bleeding complications during transfemoral transcatheter aortic valve replacement: DataData from the VIenna Cardio Thoracic aOrtic valve registrY (VICTORY).

Background: Arterial tortuosity is linked to a higher risk of adverse clinical events after transfemoral transcatheter aortic valve replacement (TF-TAVR). Currently, there are no assessment tools that can quantify this variable in three-dimensional space. This study investigated the impact of novel scoring methods of iliofemoral tortuosity on access and bleeding complications after TF-TAVR.
