REVIEW
Yousif Ahmad, Michael F Bellamy, Christopher S R Baker
Aortic valve stenosis occurs 10-20 years earlier in patients on dialysis compared with the general population. This is likely related to the exposure of the valve to a milieu that predisposes to calcification as well as increased shear stress across the valve. Objective assessment of stenosis severity is largely made using echocardiography though accurate interpretation requires an understanding of the potential pitfalls of the technique and the influence of cardiac output upon the gradient measured across the valve...

Circulating leukocyte subtypes and monocyte subsets are independent predictors of cardiovascular events. We hypothesized that an increased leukocyte subtype would predict severe coronary stenosis and extensive plaque involvement. We retrospectively analyzed clinical, laboratory, and coronary CT data in a total of 588 asymptomatic adults (69% men; mean age, 57 ± 9 years) undergoing a general health check-up. Intermediate CD14(++)CD16(+) monocyte count had the strongest association with mixed and calcified plaque scores, whereas the numbers of neutrophils and classical CD14(++)CD16(-) monocytes were significantly associated with non-calcified plaque score...

BACKGROUND: Patients with developmental spinal stenosis (DSS) are susceptible to developing symptomatic stenosis due to pre-existing narrowed spinal canals. DSS has been previously defined by MRI via the axial anteroposterior (AP) bony spinal canal diameter. However, MRI is hardly a cost-efficient tool for screening patients. X-rays are superior due to its availability and cost, but currently, there is no definition of DSS based on plain radiographs. Thus, the aim of this study is to develop radiographic indices for diagnosing DSS...

Neck trauma is a very important surgical emergency faced by ENT surgeons in day to day practice. They are potentially life threatening conditions due to the presence of many vital structures in this area. Timely presentation to the referral centre and proper multidisciplinary approach towards management plays a pivotal role in the healing pattern of the wound and prevention of serious complication like shock, sepsis, laryngeal stenosis or fistula formation. A retrospective study was done in ENT Department, NSCB Medical College, Jabalpur, Madhya Pradesh, India during the period of 2014-2016...

Cut throat injuries are one of the emergency conditions managed by ENT specialists. If not treated in time, they may lead to death. Prevention of these complications depends on immediate resuscitation by securing the airway by tracheostomy or intubation, prompt control of hemorrhage and blood replacement. The present study was conducted to study the sociodemographic profile of patients of cut throat injury, motives behind cut throat injury, site and depth of the injury, treatment given at our hospital and outcome...

Celiac stenosis may result in a pancreaticoduodenal artery aneurysm (PDAA). Celiac stenosis with a PDAA is rare and treatment guidelines are absent. Here, we report 4 cases of celiac stenosis treated using different methods. Of these, 3 involved PDAAs. The PDAAs were successfully treated with coil embolization. For celiac stenosis, we performed open surgery for decompression in 1 patient, stenting in 2 patients, and bypass grafting in 1 patient. In the patients who underwent stenting, stent-associated thrombosis occurred...

BACKGROUND: Changing patterns of referral and management of hypertrophic pyloric stenosis (HPS) in North America have recently been described. Comfort with perioperative management, anesthesia, and corrective surgery have been cited as reasons for these changes. Our primary objective was to assess pyloromyotomy outcomes between different hospital types across Canada. The secondary objective was to geospatially map all pyloromyotomies to identify regions of higher HPS incidence across Canada...

BACKGROUND: The pyriform aperture comprises the central area of facial bone structure. It is formed by the free corners of the nasal bone and the frontal processes of the maxillae, which articulate with each other at the nasomaxillary suture lines. Congenital nasal pyriform aperture stenosis might be linked to various craniofacial problems. This review presents all aspects of pyriform aperture stenosis and enlargement. METHODS: A literature search was conducted...

Situs inversus totalis and anomalous origin of the left coronary artery are rare conditions. An 87-year-old woman with both conditions presented to the authors' hospital with symptomatic aortic stenosis. She underwent aortic valve replacement (AVR) and coronary artery bypass grafting (CABG; saphenous vein graft to the left main trunk). The operator mainly stood on the left side of the patient and performed surgery without difficulty. Both, AVR and CABG were successfully performed despite these two rare conditions...

BACKGROUND: Rheumatic heart disease is a common reason for cardiovascular morbidity and mortality. Plasma levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) are known to rise in patients with MS, but the role of this compound as a non-invasive marker of left atrial (LA) dysfunction is yet to be established. The study aim was to correlate levels of NT-proBNP in patients with rheumatic mitral stenosis (MS), with echocardiographic parameters of LA function including tissue Doppler-derived strain/strain rate (S/Sr) indices, hemodynamic parameters of LA function, before and after percutaneous balloon mitral valvotomy (PBMV) for a follow up of one year...

The aim of this review was to describe recent advancements in the understanding of bicuspid aortic valve (BAV). BAV is the most common congenital cardiac anomaly, and affects between 0.46% and 1.37% of the population. There is a male predominance of approximately 3:1.While isolated BAV is found in certain patients, it is often associated with other congenital cardiac lesions, including dilatation of the thoracic aorta, coarctation of the aorta and abnormalities of the coronary anatomy. In most cases, it remains undetected until the patient contracts infective endocarditis, or calcification occurs...

Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for patients with severe aortic stenosis (AS) who are unsuitable for surgical aortic valve replacement (SAVR), and is an acceptable alternative for those at high and intermediate surgical risk. In published TAVI registries and meta-analyses, whilst women are significantly older they present with fewer comorbidities compared to men (including coronary artery disease, peripheral vascular disease, diabetes and chronic obstructive pulmonary disease)...

BACKGROUND: Prosthesis-patient mismatch (PPM) is highly prevalent among patients undergoing aortic valve replacement (AVR) to treat aortic stenosis. Data regarding the prevalence and impact of PPM on left ventricular remodeling and outcomes in patients who have undergone surgical AVR to treat pure severe aortic regurgitation (AR) are, however, scarce. METHODS: A retrospective analysis was conducted of clinical and echocardiographic data acquired from 50 consecutive patients with pure severe AR, without evidence of significant coronary artery disease, who underwent AVR between 2004 and 2010 at the authors' institution...
