PURPOSE OF REVIEW: Sutureless aortic valve replacement (AVR) has emerged as an alternative to traditional AVR for patients with aortic stenosis who present a higher surgical risk, such as the elderly, or those with small or highly calcified aortic roots. With transcatheter aortic valve implantation - the other major AVR alternative - being used in increasingly lower-risk patients, the place of sutureless valves in the AVR landscape needs to be defined. In this review, we discuss recent data and expert opinion as it pertains to the subject of sutureless AVR...

Management of the frontal sinus places great demands on the otolaryngologist. Given that the fronto-ethmoidal region is susceptible to recurrent inflammation, scarring, and stenosis, maintaining long-term patency of the frontal sinus is a difficult challenge. Oral and topical anti-inflammatory therapy, post-operative stenting, and 'home-brew' drug elution have been used for the treatment of the frontal sinus with mixed success. Recently an implant has been approved for post-operative placement into the frontal recess...

This study analyzed the potential associations of 7 myocardial fibrosis-related microRNAs with the quality of the collagen network (e.g., the degree of collagen fibril cross-linking or CCL) and the enzyme lysyl oxidase (LOX) responsible for CCL in 28 patients with severe aortic stenosis (AS) of whom 46% had a diagnosis of chronic heart failure (HF). MicroRNA expression was analyzed in myocardial and blood samples. From the studied microRNAs only miR-19b presented a direct correlation (p < 0.05) between serum and myocardium...

BACKGROUND: Considerable variability exists in normal developmental lumbar spinal canal size. This impacts the likelihood of neural compromise. Spinal canal development is complete by 17 years. As diseases incurred thereafter do not knowingly affect the developmental size of the spinal canal, it is reasonable to use a selected population undergoing abdominopelvic computed tomography (CT) examination to determine developmental lumbar spinal canal size. METHODS: Study approval was granted by the Clinical Research Ethics Committee...

Because of the protective effect of estrogen for atherosclerosis, the prevalence of acute coronary syndrome in women before menopause is low. We report a rare case of unstable angina in a young Japanese female who had a history of cigarette smoking and contraceptive use. Her coronary stenosis was successfully treated by percutaneous coronary intervention.

BACKGROUND: In high-risk patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR) diabetes mellitus (DM) is a common comorbidity. It is known to increase the risk of arteriosclerosis and adversely affect morbidity, mortality for all types of cardiovascular disease, and post-procedural outcome after percutaneous and surgical procedures. Moreover, DM is known to facilitate the genesis of renal failure (RF). Pre-existing RF seems to increase the rate of acute kidney injury (AKI), which is a powerful short- and midterm predictor of mortality in patients undergoing TAVR...

Neourethral diverticulum secondary to distal neourethral stenosis is not uncommon after proximal hypospadias repair. We describe a technique using the neo urethral diverticular roof and overlying skin as a composite flap to reconstruct the urethral stenosis distal to the diverticulum. The composite flap is advanced distally for reconstruction of the stenosed urethra either as a tube or as an onlay. Urethra at the diverticular bed is tubularized to reduce its caliber. This technique has yielded excellent results in three children...

BACKGROUND: Epicardial adipose tissue (EAT) is a metabolically active fat depot that is associated with incident coronary artery disease (CAD) and major adverse cardiovascular events. The relationship between EAT and myocardial ischemia remains unclear. This study investigated the relationship between EAT volume and the presence of perfusion defects on myocardial computed tomographic perfusion imaging (CTP) and functional stenoses on invasive fractional flow-reserve (FFR). METHODS: Data were obtained from a previous prospective cross-sectional study in patients with suspected CAD...

OBJECTIVES: We aimed to determine whether body mass index (BMI) is a prognostic indicator for long-term, all-cause mortality in patients undergoing transcatheter aortic valve implantation (TAVI). BACKGROUND: Obesity in patients with established cardiovascular disease has previously been identified as an indicator of good prognosis, a phenomenon known as the "obesity paradox". The prognostic significance of BMI in patients with severe aortic stenosis (AoS) undergoing TAVI is a matter of current debate, as published studies are scarce and their results conflicting...

BACKGROUND: In this study, we sought to analyze the incidence and relevance of von Willebrand factor (VWF) abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI), especially on perioperative bleeding. Furthermore, we hypothesized that, similar to aortic valve surgery, TAVI results in a restoration of VWF abnormalities. METHODS AND RESULTS: We performed a prospective analysis of periinterventional VWF parameters in 74 patients (80±7years, female in 37...

Nuclear factor κappa B (NF-κB) is an important transcription factor in the development and progression of coronary artery disease (CAD). Recent evidence suggests that -94 ATTG ins/del mutant in the promoter of NFKB1 gene is an essential functional mutant. The present study demonstrated the frequencies of the del/del (DD) genotype and del (D) allele were significantly higher in CAD patients than in controls. CAD patients carrying mutant DD genotype had worse stenosis of diseased coronary arteries compared to those carrying ins/ins (II) or ins/del (ID) genotype...
