Transcatheter aortic valve replacement (TAVR) has gained increasing acceptance for patients with aortic disease. A rare but fatal complication prosthetic valve endocarditis (PVE) could greatly influence the clinical outcomes of TAVR. This meta-analysis aims to pin down the predictors of PVE in TAVR patients.

We performed a systematic search for studies that reported the incidence and risk factors of PVE after TAVR. Data on studies, patients, baseline characteristics, and procedural characteristics were abstracted. Crude risk ratios (RRs) and 95% confidence intervals for each predictor were calculated by the use of random-effects models. Heterogeneity assumption was assessed by an I2 test.

We obtained data from 8 studies that included 68,805 TAVR patients, of whom 1,256 (1.83%) were diagnosed with PVE after TAVR. 280 patients died within the 30-days of PVE diagnosis and the pooled in-hospital mortality was 22.3%. The summary estimates indicated an increased risk of PVE after TAVR for males (RR 1.53, P = .0001); for patients with orotracheal intubation (RR 1.65, P = .01), new pacemaker implantation (RR 1.46, P = .003), and residual aortic regurgitation (≥2 grade) (RR 1.62, P = .05); while older age (RR 0.97, P = .0007) and implantation of a self-expandable valve (RR 0.74, P = .02) were associated with a lower risk of PVE after TAVR.

Clinical characteristics and peri- procedure factors including age, male sex, valve type, orotracheal intubation, pacemaker implantation, and residual regurgitation were proven to be associated with the occurrence of PVE-TAVR. Clinicians should pay particular attention to PVE when treating TAVR patients with these predictors.

The aim of this study was to present an extrapleural approach for the closure of patent ductus arteriosus (PDA), with the repair of aortic coarctation (CoA) in the same session, in critically ill newborns and infants as an alternative to the transpleural surgical technique.

Between December 2007 and November 2010, 44 critically ill patients with PDA and coarctation of the aorta were operated on during the same session with the extrapleural approach. The diagnoses of the patients were made by transthoracic echocardiography (TTE). We investigated the aortic arch, the length of the coarctation segment, peak-to-peak gradients, the aortic valve, and intracardiac defects prior to the surgery using TTE. Cardiac angiography was performed to determine whether the patients were suitable for an interventional approach in hemodynamically stable patients. Twenty-eight patients had congestive heart failure with mild to moderate pulmonary and systemic hypertension. The median gestational age and weight of neonates were he same session may be performed safely and with acceptable mortality and morbidity via an extrapleural approach. Interventional approach as a less invasive method may be used in patients who have developed recoarctation.Mitral regurgitation (MR) is a common valvular heart disease, which can be classified into primary and secondary, according to the cause. Primary mitral regurgitation (PMR) is caused by rheumatic fever, degenerative changes, valve prolapse, etc. The appearance of clinical symptoms has always been the best indicator of surgical intervention in patients with severe PMR, but for asymptomatic patients, the best treatment has been controversial. The choice of follow-up observation or early surgery has different results in different randomized studies. Two-dimensional echocardiography is the most commonly used detection method for evaluating MR, but its evaluation of the degree of reflux may be inaccurate, and there are differences in the outcomes of patients with asymptomatic PMR. Recent studies have shown that three-dimensional echocardiography, cardiac magnetic resonance, speckle-tracking echocardiography, brain natriuretic peptide, and exercise stress test can optimize the timing of surgery for asymptomatic patients and judge the asymptomatic of PMR.

In cardiac surgery, myocardial protection is required during cross-clamping followed by reperfusion. The use of cardioplegic solutions helps preserve myocardial energy stores, hindering electrolyte disturbances and acidosis during periods of myocardial ischaemia. This study aimed to compare the efficacy and safety between the histidine-tryptophan-ketoglutarate (HTK) solution and blood cardioplegia in various cardiac surgeries.

Three-hundred-twenty patients aged 30-70 years old undergoing various cardiac surgeries were randomized into the HTK group and the blood cardioplegia group. The ventilation time, total bypass time, cross-clamp time, length of intensive care unit (ICU) or hospital stay, and postoperative complications were analyzed.

The total bypass time and cross-clamp time were significantly shorter in the HTK group than in the blood cardioplegia group (P < 0.001). Segmental wall motion abnormalities (SWMA) at postoperative echocardiography were significantly higher in in the blood cardioplegiropic support than blood cardioplegia. Custodiol cardioplegia is a safe and feasible option that can be used as an effective substitute for blood cardioplegia to enhance myocardial protection.

The use of HTK cardioplegia was associated with significantly shorter cross-clamp time, bypass time, duration of mechanical ventilation, length of ICU stay, and length of hospital stay. It is associated with less incidence of postoperative segmental wall abnormalities and less need for inotropic support than blood cardioplegia. Custodiol cardioplegia is a safe and feasible option that can be used as an effective substitute for blood cardioplegia to enhance myocardial protection.The occurrence of a giant ruptured aneurysm originating from the noncoronary sinus of Valsalva in the right atrium is extremely rare. Herein, a case is presented of a giant ruptured noncoronary sinus of Valsalva aneurysm (SVA) that was protruding into the right atrium, which was almost completely occupied by an aneurysm. A 61-year-old female was referred to the hospital for exertional palpitation and dyspnea. While a surgical repair was performed by resection of the aneurysm and a sinus remodeling with a patch of fresh bovine pericardium, a very rare case was observed. It was a giant ruptured noncoronary sinus of aneurysm that completely occupied the right atrium, which was difficult to distinguish from the coronary aneurysm. It is also believed that various imaging examinations, such as cardiac computed tomography angiogram (CCTA) and transthoracic echocardiogram (TTE), were useful for the diagnosis.

The impact of biologics used in PsA management on T cells is unknown. This study evaluated the effect of tumour necrosis factor-alpha (TNFα), interleukin-17A (IL-17A), and IL-6 receptor (IL-6R) blockers on T cell function in PsA patients and healthy controls peripheral blood mononuclear cells (PBMCs).

A total of 111 PsA patients and 32 healthy controls were recruited. PBMCs were co-cultured in presence of the biologics. T cell activation and proliferation were analysed by flow cytometry and cytokines in supernatants were measured by ELISA. The effect of biologics on lymphocyte proliferation was determined in response to phytohemagglutinin (PHA).

Activated CD4+CD25+ T cells were significantly reduced by adalimumab (ADA) in PsA patients as compared to medium, ixekizumab (IXE), and tocilizumab (TCZ), while in healthy controls, ADA reduced the activated CD4+CD25+ T cells non-significantly. Elevated TNFα and IL-1β levels were produced in supernatants of PsA patients as compared to healthy controls. TNFα, IL-17A, IL-1β, and MMP-3 levels were reduced by ADA compared to medium (p<0.0001, p<0.0004, p<0.04, p<0.04, respectively). IXE reduced IL-17A (p<0.0001) but not the other cytokines. ADA had higher susceptibility to inhibit PHA-induced proliferation in both PsA patients and healthy controls (p<0.03) as compared to IXE and TCZ.

Both TNF and IL-17A blockers are suitable for PsA treatment, but exhibit different activity on T cells. Moreover, the study reveals part of the mechanism exerted by ADA and provides a possible explanation for TCZ inefficacy in PsA.

Patients with rheumatoid arthritis (RA) have an accelerated progression of atherosclerosis. The aim of this study was to examine the associations between subclinical atherosclerosis, assessed by intima-media thickness (IMT), and regulators of bone formation, markers of bone turnover and bone mineral density (BMD) in patients with RA.

Patients with new-onset RA (n=79), aged ≤60 years at diagnosis, were consecutively included in a study of development of atherosclerosis. Ultrasound measurement of IMT of the common carotid artery was undertaken at inclusion (T0) and after 11 years (T11) (n=54). Bone turnover biomarkers were examined in samples collected at T0 and T11. BMD was assessed at T11.

In patients with RA, osteocalcin (OCN) and osteoprotegerin (OPG) measured at T11 were significantly associated with IMT at T11, adjusted for systolic blood pressure (SBP) and age. BMD at T11 and the bone turnover markers procollagen type 1 N-terminal propeptide (P1NP) and carboxy-terminal crosslinked C-terminal telopeptide (CTX) were not associated with IMT. OPG, OCN and sclerostin at T0 were significantly associated with IMT at T11, and OPG and OCN at T0 were associated with change in IMT from T0 to T11. The associations between IMT and bone biomarkers were stronger in patients with joint erosions at onset of RA, than in patients with non-erosive disease.

Atherosclerosis in patients with RA is associated with OPG and OCN, but not with BMD or markers reflecting ongoing bone turnover, indicating that atherosclerosis is not associated with bone turnover per se.

Early and correct diagnosis would be beneficial for outcomes of rheumatoid arthritis (RA), but there are some limitations in current diagnostic tools. In this study, we aimed to evaluate the diagnostic value of circulating miR-22-3p and let-7a-5p in RA.

Seventy-six RA patients, 30 systemic lupus erythematosus patients, 32 Sjögren's syndrome patients and 36 healthy donors recruited at the First Affiliated Hospital of Fujian Medical University (China) were included in this study. Circulating miR-22-3p and let-7a-5p in plasma were measured using reverse transcriptase quantitative PCR and serum cytokines were detected by cytometric bead array. The participants' clinical materials were also collected. Receiver operating characteristic curve analysis and correlation analysis were performed to assess the potential value of circulating miRNAs in RA.

Circulating miR-22-3p and let-7a-5p are significantly increased in RA patients and able to distinguish RA patients from other populations. Circulating let-7a-5p has been shown to improve the diagnostic ability of current laboratory indicators anti-cyclic citrullinated peptide antibodies and rheumatoid factor.
