A hazardous collateral pathway following asymptomatic lead-related venous occlusion?

Routine venography should be performed before the device upgrade. Clinicians should not be unconcerned because of the lack of symptoms following lead-related venous occlusion. Knowledge of collateral anatomy is essential for future interventional plans.

The burden of atrial fibrillation and heart failure in hospitalized patients: A real-world survey in a nationwide snapshot.

Purpose: Atrial fibrillation (AF) and heart failure (HF) are common and commonly coexisting cardiovascular diseases in hospitalized patients. We report the absolute number and interrelation between AF and HF, assess the daily burden of both diseases on the healthcare system, and describe the medical treatment in a real-world, nationwide conducted snapshot survey.

Methods: A questionnaire was equally distributed to various healthcare institutions.

Does sympathetic nervous system modulate tumor progression? A narrative review of the literature.

Objective: The role of the sympathetic nervous system (SNS) in tumor development, progression and metastasis is studied for more than half a century and is attracting more attention during the last years. In this narrative review, we aim to a chronological and methodological presentation of the most interesting and pioneering studies on the subject.

Methods: The complexity of the autonomic nervous system's interaction with the immune system, its direct and indirect effects on tumors and their surrounding tissues, plus the diversity and heterogeneity in the design and methodology of the studies, provide hard-to-interpret data and, at times, controversial findings.

The electrocardiogram of ventricular capture during transcutaneous cardiac pacing.

Background: Transcutaneous cardiac pacing (TCP) is deeply entwined with the problem of assessing ventricular capture on the electrocardiogram (ECG). We sought clarification of ventricular capture during TCP.

Methods: We studied one hundred and ten patients (75 ± 12 years) with bradycardia who underwent pacemaker or implantable cardioverter-defibrillator implantation.

Follicle-Stimulating Hormone Receptor (FSHR): A Promising Tool in Oncology?

The cellular pathway of follicle-stimulating hormone (FSH) and its receptor (FSHR) is typically involved in reproduction in mammals. In humans, the FSHR is normally found in cells of the testis and the ovary, while it is scarcely expressed in other normal tissues. The expression of FSH/FSHR is studied in prostate, thyroid, and ovarian cancer tissues.

What is the best approach in a patient with a failed aortic bioprosthetic valve: transcatheter aortic valve replacement or redo aortic valve replacement?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether transcatheter aortic valve-in-valve replacement (viv-TAVR) or redo aortic valve replacement (rAVR) is the best strategy in a patient with a degenerative bioprosthetic aortic valve. Altogether, 162 papers were found using the reported search, of which 12 represented the best evidence to answer the question.

Mitral valve repair of isolated posterior leaflet prolapse: resect or respect?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is best in a patient with posterior leaflet prolapse to resect tissue from the posterior leaflet or to preserve the leaflet tissue by only adding neochordal reconstruction. Altogether, 279 papers were found using the reported search, of which 16 represented the best evidence to answer the clinical question.

Simultaneous occurrence of coronary artery disease and lung cancer: what is the best surgical treatment strategy?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether combined surgical procedures in one or two stages are the best surgical treatment strategy in patients with simultaneous coronary artery disease and lung cancer. Altogether, 264 papers were found using the reported search; of which, 15 represented the best evidence to answer the clinical question.

Right upper lobe partial anomalous pulmonary venous connection.

Partial anomalous pulmonary venous return (PAPVR) is a left-to-right shunt where one or more, but not all, pulmonary veins drain into a systemic vein or the right atrium. We report a case of a 45-year-old male with PAPVR to superior vena cava which was incidentally discovered during a right lower bilobectomy for lung cancer.

Is aortic valve repair or replacement with a bioprosthetic valve the best option for a patient with severe aortic regurgitation?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether it is best to repair or replace the aortic valve with a bioprosthesis in young patients with severe aortic regurgitation as the patients do not like to take warfarin for the rest of life. Altogether 74 papers were found using the reported search, of which 10 represented the best evidence to answer the clinical question.

Patients with gastroesophageal reflux disease and respiratory manifestations do not present lung function disorders during cardiopulmonary exercise test.

Gastroesophageal reflux disease (GERD) has been associated with a variety of pulmonary manifestations, but it is unclear if gastroesophageal reflux causes any abnormality in pulmonary function. Cardiopulmonary exercise test (CPET) is a specialized method that is used to evaluate respiratory function during exercise. The aim of this study was to reveal any abnormality of pulmonary function in patients with GERD and respiratory symptoms.

Kümmell' s disease: A rare spine entity in a young adult.

Over 100 years ago, Dr Hermann Kümmell described a rare clinical entity in which patients, after a trivial trauma and an asymptomatic period, developed a progressive vertebral body collapse and a painful kyphosis. We present the case of a 31years old heavy labourer, fitting Kümmell's criteria. The patient referred to us in an incapacitated state, due to persistent back pain.
