Mitral annular calcification can pose a formidable surgical challenge in the setting of mitral valve replacement for mitral stenosis. Although there are reports of transapical valve-in-valve transcatheter mitral valve replacement in the setting of degenerated bioprosthetic mitral valve replacement, there is less experience with transcatheter mitral valve replacement for mitral annular calcification. This report describes a patient who previously received a transcatheter aortic valve replacement and then subsequently underwent a minimally invasive right thoracotomy for transcatheter mitral valve replacement with a successful result...

OBJECTIVE: Robotically assisted minimally invasive direct coronary artery bypass is an alternative to sternotomy-based surgery in properly selected patients. Identifying the left anterior descending artery when it is deep in the epicardial fat can be particularly challenging through a 5- to 6-cm mini-thoracotomy incision. The objective of this study was to evaluate a technique for predicting conversion to sternotomy or complicated left anterior descending artery anastomosis using preoperative cardiac-gated computed tomography angiograms...

Positron emission tomography (PET) is a non-invasive imaging technique used to assess various brain functions, including cerebral blood flow, glucose metabolism, and neurotransmission, in the living human brain. In particular, neurotransmission mediated by the monoamine neurotransmitters dopamine, serotonin, and norepinephrine, has been extensively examined using PET probes, which specifically bind to the monoamine receptors and transporters. This useful tool has revealed the pathophysiology of various psychiatric disorders, including schizophrenia, and the mechanisms of action of psychotropic drugs...

Background: Surgical stabilization of displaced midshaft clavicle fracture can be achieved by an intramedullary nail or plate. When intramedullary nail is used, one of the dreaded complications is the migration of nail. We have used a screw intramedullary device with screw mechanism at one end which can get hold in the medial cancellous bone, thus preventing chances of nail migration. The aim of our study was to evaluate the clinical outcome following elastic stable screw intramedullary nailing for the fixation of midshaft clavicle fractures...

BACKGROUND: Headscarf use is becoming more common throughout the world. Many articles describe the problem of aspirated headscarf pins but few if any give technical details for retrieval or innovative methods of removal if traditional bronchoscopy fails particularly in the pediatric population. Herein, we describe our method of deep sedation with laryngeal mask airway (LMA) and flexible bronchoscopy (FB) and retrieval with a stepwise algorithm if traditional FB fails. METHODS: A retrospective review of pediatric patients with aspirated headscarf pins was performed...

Background: Minimally invasive mitral valve surgery (MVS) via right mini-thoracotomy has recently attracted a lot of attention. Minimally invasive MVS shows postoperative results that are comparable to those of conventional MVS through the median sternotomy as per various earlier studies. Methods: Between 2000 and 2016, a total of 669 isolated mitral valve procedures for isolated mitral valve regurgitation were performed. A propensity score-matched analysis was generated for the elimination of the differences in relevant preoperative risk factors between the cohorts and included 227 patient pairs...

BACKGROUND: The reduction of RV function after cardiac surgery is a well-known phenomenon. It could persist up-to one year after the operation and often leads to an incomplete recovery at follow-up echocardiographic control. The aim of the present study is to analyze the impact of different modalities of pericardial incision (lateral versus anterior) and of myocardial protection protocols (Buckberg versus Custodiol) onto postoperative RV dynamic by relating two- and three-dimensional echocardiographic parameters in patients undergoing mitral valve repair through minimally invasive or traditional surgery approach...

PURPOSE OF REVIEW: In this article, we focus on recent published data (2017) on the management of gynecologic sarcomas. RECENT FINDINGS: The most significant data published in 2017 develop definition of a new molecular subtype of high grade endometrial stromal sarcoma (ESS) using molecular technics added to histological analysis. The identification of a new translocation on presumed uterine leiomyosarcoma (LMS) points to refinement of nosological classification, with fragmentation of even rare tumors into distinct molecular entities: gynecologic sarcomas are now distinguished into distinct entities from a heterogeneous group of tumors...

OBJECT: Olfactory groove meningiomas (OGMs) constitute a unique subset of intracranial meningiomas, since they usually remain clinically silent for a long period of time, and they may be of large size upon their diagnosis. Their surgical management remains quite challenging. The surgical and the neuropsychological outcome of patients with OGM are presented in our current study, in order to establish a basis for developing efficacious surgical strategies for the management of this clinico-pathological entity...

In the framework of urologic oncology, mini-invasive procedures have increased in the last few decades particularly for urothelial carcinoma. One of the essential elements in the management of this disease is still the diagnosis, which strongly influences the choice of treatment. The histopathologic evaluation of the tumor grade is a keystone of diagnosis, and tumor characterization is not possible with just a macroscopic evaluation. Even today intraoperative evaluation remains difficult despite the emergence of new technologies which use exogenous fluorophore...

Endoscopic submucosal dissection or widespread endoscopic resection allow the radical removal of circumferential or near-circumferential neoplastic esophageal lesions. The advantage of these endoscopic methods is mini-invasivity and low risk of major adverse events compared to traditional esophagectomy. The major drawback of these extensive resections is the development of stricture - the risk is 70-80% if more than 75% of the circumference is removed and almost 100% if the whole circumference is removed. Thus, an effective method to prevent post-ER/ESD esophageal stricture would be of major benefit, because treatment of strictures requires multiple sessions of endoscopic dilatation and may carry a risk of perforation...
