BACKGROUND: The concomitant presence of mitral stenosis (MS) in the setting of symptomatic aortic stenosis represent a clinical challenge. Little is known regarding the outcome of mitral stenosis (MS) patients undergoing transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR). Therefore, we sought to study the outcome of MS patients undergoing aortic valve replacement (AVR). METHOD: Using weighted data from the National Inpatient Sample (NIS) database between 2011 and 2014, we identified patients who were diagnosed with MS...

While the long-term outcome of surgical aortic valvotomy (SAV) appears to be better than that of balloon aortic valvuloplasty (BAV) as the primary procedure of aortic valve stenosis, the surgical strategies and techniques of treating aortic valve disease in children in other situations remain controversial. Valve repair should be first considered while replacement is still unavoidable in some cases, and new repair techniques developed by innovative surgeons are gradually becoming adopted. Some complex repair procedures such as cusp extension, leaflet replacement/reconstruction have provided satisfactory outcomes...

The wheat blast fungus (Triticum pathotype of Pyricularia oryzae) first arose in Brazil in 1985 and has recently spread to Asia. Resistance genes against this new pathogen are very rare in common wheat populations. We screened 520 local landraces of common wheat collected worldwide with Br48, a Triticum isolate collected in Brazil, and found a highly resistant, unique accession, GR119. When F2 seedlings derived from a cross between GR119 and Chinese Spring (CS, susceptible control) were inoculated with Br48, resistant and susceptible seedlings segregated in a 15:1 ratio, suggesting that GR119 carries two resistance genes...

Herein is presented the case of an 83-year-old male patient in cardiogenic shock with acute aortic regurgitation that occurred six years after aortic valve replacement (AVR) with a 23 mm Trifecta™ valve. Prosthesis endocarditis was initially suspected because of a floating structure attached to the aortic valve that was visible on echocardiography. Emergency redo-AVR surgery was performed, but no signs of endocarditis were found intraoperatively. Hence, cusp tearing of the implanted bioprosthesis was considered to be the reason for the severe aortic regurgitation...

BACKGROUND: Despite the limited durability of biological aortic valves, increasing numbers of younger patients are choosing to receive them, due mainly to the lack of a need for permanent anticoagulation. Few data exist, however, regarding the outcomes of valve replacement in patients aged <55 years, and additional data are required in this patient population. METHODS: Between 1993 and 2014, at the authors' institution, a total of 448 patients (237 males, 101 females; mean age 45...

BACKGROUND New-onset extreme right axis deviation and right bundle branch block (RBBB) are rare during acute myocardial infarction (AMI), and has only been reported in several cases reflecting the severity of AMI. It could predict severe clinical complications and higher risks in coronary artery disease. Although there is little electrophysiological explanation, the complications are severe. They should be emphasized in newly diagnosed extreme right axis deviation and RBBB in AMI. CASE REPORT A 72-year-old male was admitted to our department with a chief complaint of intermittent retrosternal chest pain and was diagnosed with extensive anterior myocardial infarction with RBBB, by elevated myocardial enzymes and ECG...

A consensus rust QTL was identified within a 1.25 cM map interval of A03 chromosome in cultivated peanut. This map interval contains a TIR-NB-LRR R gene and four pathogenesis-related genes. Disease resistance in plants is manifested due to the specific interaction between the R gene product and its cognate avirulence gene product (AVR) in the pathogen. Puccinia arachidis Speg. causes rust disease and inflicts economic damages to peanut. Till now, no experimental evidence is known for the action of R gene in peanut for rust resistance...

Retinal arteriolar narrowing increases with age and predict adverse cardiovascular outcomes. Telomere length keeps track of the division of somatic cells and is a biomarker of biological age. We investigated to what extent retinal arteriolar diameters are associated with biological age, as captured by leukocyte telomere length (LTL). In 168 randomly selected Flemish participants from the family-based population study FLEMENGHO (mean age, 46.2 years) at baseline, of whom 85 underwent a follow-up examination (median, 4...

About 60% of patients with paradoxical low-flow, low-gradient (PLF-LG) aortic stenosis (AS) have a severe disease that justifies aortic valve replacement (AVR). The first step in patients with symptomatic PLF AS should be to rule out measurement errors and treat hypertension. The second step is to distinguish pseudo-severe from true severe AS (TSAS). The third step is to select the optimal treatment modality at the right time. Regarding the second step, projected aortic valve area calculated using stress echocardiography is superior to traditional severity criteria (AVA < 1...

BACKGROUND: Idiopathic VE shows predilection to sites within the left ventricular base such as the outflow tract/aortic sinuses, LV summit and adjacent to the aorto-mitral continuity. We characterize VE arising from the inferior septum of the LV base that were successfully managed by LV endocardial ablation from the infero-septal recess of the LV. OBJECTIVES: To determine the incidence, electrocardiographic, electrophysiological findings and anatomical features associated with ventricular ectopy (VE) arising from the basal infero-septal process of the left ventricle (ISP-LV) ablated using an LV endocardial approach via the infero-septal recess of the left ventricle...

Spectral analysis of the arterial pressure waveform, using specialized hardware, has been used for the retrospective calculation of the 'Spectral Peak Ratio' (SPeR) of the respiratory and cardiac arterial spectral peaks. The metric can quantify the cardiovascular response to volume loading by analysing the effect of changing tidal volume (indexed to body weight) (VTI ) on pulse pressure variability. In this pilot study, the feasibility of real-time SPeR calculation, using a mobile computer which was wirelessly connected to the patient monitor, was evaluated by examining the determinants of SPeR in 60 cardiac-surgical patients...
