Write a review text or point-of-view that takes into account the interests, if not of all, but of most readers of a scientific journal is an arduous task. The editorial can be grounded in published articles, even in a single article of undeniable importance and, it can also represent a trend of specialty. Therefore, especially for the sake of the reader's motivation, the present text was freely designed to discuss some cardiology enigmas in the context of the heart valve and coronary artery disease (CAD). Concerning the CAD five well-known enigmas will be considered: 1) The absence of arteriosclerosis in intramyocardial coronary arteries; 2) The unique and always confirmed superior evolution of the left internal thoracic artery as a coronary graft; 3) The prophylactic left internal thoracic artery graft in mildly-stenosed coronary lesions, and; 4) The high incidence of perioperative atrial fibrillation (AF) in patients with CAD, and; 5) The handling of disease-free saphenous vein graft at the time of reoperation...

Background Coronary endarterectomy and patch angioplasty for the left anterior descending (LAD) artery have been shown to be effective adjunct techniques to surgical revascularization for severe coronary lesions. The objective of this study is to review the short- and long-term results of these two methods in our institution. Methods We retrospectively reviewed 166 consecutive patients who underwent internal thoracic artery grafting to the LAD, with either adjunct endarterectomy (95 patients) or patch angioplasty (71 patients) between 2002 and 2014...

BACKGROUND: Empyema refers to pus in the pleural space, commonly due to adjacent pneumonia, chest wall injury, or a complication of thoracic surgery. A range of therapeutic options are available for its management, ranging from percutaneous aspiration and intercostal drainage to video-assisted thoracoscopic surgery (VATS) or thoracotomy drainage. Intrapleural fibrinolytics may also be administered following intercostal drain insertion to facilitate pleural drainage. There is currently a lack of consensus regarding optimal treatment...

OBJECTIVE: The balance between nitric oxide (NO)-sensitive and -insensitive forms of soluble guanylate cyclase (sGC) has been demonstrated to be disrupted in certain lifestyle-related diseases. However, it remains unclear whether type 2 diabetes results in a shift of sGC to the NO-insensitive form. This study addressed this issue in the human blood vessel. METHODS: Internal thoracic arteries were obtained from patients undergoing coronary artery bypass grafting...

Hyperlipidemia is an important risk factor for atherosclerosis and is frequently seen in patients with erectile dysfunction (ED). This study was designed to evaluate whether the acute effect of native low-density lipoprotein (nLDL) on intracavernosal pressure (ICP) is reversible and related to plasma asymmetrical dimethylarginine (ADMA), endogenous inhibition of endothelial nitric oxide synthase (eNOS) levels and eNOS expression in cavernous tissues. Hyperlipidemia was induced by a single dose of intravenous 4 mg kg(-1) nLDL...

Monitoring and controlling respiratory motion is a challenge for the accuracy and safety of therapeutic irradiation of thoracic tumors. Various commercial systems based on the monitoring of internal or external surrogates have been developed but remain costly. In this article we describe and validate Madibreast, an in-house-made respiratory monitoring and processing device based on optical tracking of external markers. We designed an optical apparatus to ensure real-time submillimetric image resolution at 4 m...

INTRODUCTION: A new era has begun in the last two decades with the advent of endovascular methods in the therapy of blunt thoracic aorta injuries. Our experiences with the endovascular interventions of blunt aortic trauma in the Cardiovascular Center of Semmelweis University are summarised here. METHODS: We included those patients who underwent endovascular intervention due to blunt aortic trauma in a university hospital between 1998 and 2014. The statistical analysis was performed with the use of Excel...

An anterolateral thigh flap was salvaged using 110 medical leeches in the absence of an available vein for reanastomosis. After surgical construction of the flap for full-thickness thoracic wall reconstruction, the patient developed complete venous occlusion. Specifically, the anastomotic vein developed complete occlusion, and the internal jugular vein had a thrombus. In addition, because the lung was posterior to the flap, the angiogenic area of the flap was very small. When the medical leeches were first applied, the flap showed prominent venous congestion...

We placed a superficial serratus anterior plane catheter in an elderly woman with dementia and elevated clotting times who presented with multiple rib fractures after a mechanical fall. She was not a surgical candidate, and treatment consisted of conservative management with physical therapy and pain control. She was not a candidate for a patient-controlled analgesia regimen because of her dementia. Given her elevated international normalized ratio, thoracic epidural and paravertebral analgesia was also contraindicated...

A systematic review was conducted to describe the quality and characteristics of prediction models for prevalent pulmonary tuberculosis (PTB) in adults at routine TB care settings. A prediction model was defined as the combination of two or more clinical predictors designed to estimate the probability of having TB. Studies using culture-confirmed PTB as reference standard were included. Models for in-patients, children or specific patient populations were excluded. PubMed, Scopus and the Cochrane Library and abstracts from the International Union Against Tuberculosis and Lung Disease, American Thoracic Society and European Respiratory Society conferences were searched...

There is a lack of specific tools for risk stratification in patients who undergo MitraClip implantation. We aimed at combining preprocedural variables with prognostic impact into a specific risk model for the prediction of 1-year mortality in patients undergoing MitraClip implantation. A total of 311 consecutive patients who underwent MitraClip implantation were included. A lasso-penalized Cox-proportional hazard regression model was used to identify independent predictors of 1-year all-cause mortality. A nomogram (GRASP [Getting Reduction of mitrAl inSufficiency by Percutaneous clip implantation] nomogram) was obtained from the Cox model...

INTRODUCTION: The deep inferior epigastric perforator (DIEP) flap is a reliable and reproducible technique for autologous microsurgical breast reconstruction. Several recipient vessels sites for microvascular anastomosis have been described such as the internal thoracic vessels, the thoracodorsal vessels, and the circumflex scapular vessels. Nonetheless, the choice of the recipient site depends mainly on individual operator's experience and preferences, and currently the best recipient vessel site is under debate...

Chronic obstructive pulmonary disease is a major cause of morbidity and mortality worldwide and an important cause of disability. A thorough patient-centered outcome assessment, including not only measures of lung function, exercise capacity and health-related quality of life, but also of functional capacity and performance in activities of daily life, is imperative for a comprehensive management of chronic obstructive pulmonary disease. This American Thoracic Society Seminar Series is devoted to help clinicians substantiate their choice of functional outcome measures in this population...

The Fleischner Society Guidelines for management of solid nodules were published in 2005, and separate guidelines for subsolid nodules were issued in 2013. Since then, new information has become available; therefore, the guidelines have been revised to reflect current thinking on nodule management. The revised guidelines incorporate several substantive changes that reflect current thinking on the management of small nodules. The minimum threshold size for routine follow-up has been increased, and recommended follow-up intervals are now given as a range rather than as a precise time period to give radiologists, clinicians, and patients greater discretion to accommodate individual risk factors and preferences...

BACKGROUND: South Africa's crude death rate was recorded as the highest in the world in 2014. In 2013, 47 murders occurred daily nationwide, and it was confirmed that sharp force fatalities were frequent events. The aim of our study was to review the fatalities of persons admitted to the Pretoria Medico-Legal Laboratory over a two-year period. Understanding the magnitude of the problem, identifying the most commonly injured area and the mechanism of death in cases where the patient died in hospital could aid in the clinical management of some of these cases in order to reduce mortality...

A spinal cord injury (SCI) interferes with the autonomic nervous system (ANS). The effect on the cardiovascular system will depend on the extent of damage to the spinal/central component of ANS. The cardiac changes are caused by loss of supraspinal sympathetic control and relatively increased parasympathetic cardiac control. Decreases in sympathetic activity result in heart rate and the arterial blood pressure changes, and may cause arrhythmias, in particular bradycardia, with the risk of cardiac arrest in those with cervical or high thoracic injuries...
