8; IQR -0.1, 2.1; p=0.001). Freedom from reoperation was longer for patients following Doty repair than the single-patch technique (p=0.008).

The Doty repair provides longer freedom from reoperation following supravalvular aortic stenosis repair compared to a single-patch technique, likely through a greater increase in the sinotubular junction at the time of initial operation.

Early coronary ischemic events are uncommon after cardiac surgery, with little known about their management or associated outcomes. We evaluated clinical outcomes of patients undergoing coronary angiography (CAG)±percutaneous coronary intervention (PCI) or redo-coronary artery bypass grafting (redo-CABG) for suspected coronary ischemia within 3 weeks of index cardiac surgery.

This is a retrospective observational study based on data from 53,287 patients who underwent cardiac surgery at our institution (1996-2017). 180 patients (0.34%) satisfied the inclusion criteria. learn more The primary outcome was 1-year all-cause mortality. Statistical evaluation involved chi-square, ANOVA, Kaplan-Meier, and ROC analyses.

Most of the CAG+/-PCI and redo-CABG procedures occurred in the first 2 weeks after index cardiac surgery. Patients presenting with STEMI/NSTEMI had the lowest 1-year mortality (13.5%), followed by patients with ventricular tachycardia/fibrillation (VT/VF) (28.1%), and worst in patients with non-VT/VF arrestth overt signs/symptoms of myocardial ischemia following index cardiac surgery, TnT is not a reliable marker of underlying coronary or graft obstruction, but is a robust predictor of 1-year mortality.

The risks of ascending aortic dilation and indications for intervention in pediatric patients are unclear. Given the concern for aortic size mismatch with growth, larger ascending aortic diameters have been accepted in pediatric patients. The purpose of this study was to evaluate the effectiveness of ascending aortic reduction at the time of aortic valve surgery and its effect on recurrent aortic regurgitation.

A retrospective 8-year observational review (2010-2018) was conducted in pediatric patients with dilated ascending aorta undergoing aortic valve surgery at a single institution.

Forty-seven patients underwent ascending aortoplasty during aortic valve surgery, of which 39 patients with complete data points had preoperative mean ascending aortic Z-scores of 5.35 ± 1.52 reduced to 1.22 ± 1.63 (P < .001) postoperatively. Ascending aortic Z-scores remained similar at 1.37 ± 1.72 at latest follow-up (P= .306). In contrast our matched control group (n= 39) without ascending aortoplasty had preoperatigrowth.

The stentless porcine aortic root prosthesis (SPAR) has been described as a suitable valve for right ventricular outflow tract reconstruction (RVOTR). Indiana University Methodist Hospital in Indianapolis, Indiana began using this valve for RVOTR in 1998. This study reports medium-term to late- term outcomes of the valve in the pulmonary position.

A retrospective chart review was conducted of patients older than 18 years of age who underwent RVOTR with a SPAR between April 2000 and October 2019. Primary outcomes included survival and freedom from any valvular reintervention. Secondary outcomes included endocarditis and conduit dysfunction detected by routine echocardiography or cardiac magnetic resonance imaging.

A total of 135 patients underwent RVOTR with a SPAR at a median age of 32.4 years (range, 18 to 71 years). Of these patients, 129 had previous surgery. Indications included pulmonary insufficiency (90.4%), stenosis (34.8%), endocarditis (7.4%), and carcinoid (4.4%). Median follow-up was 2.97 yetion.

Excellent outcomes of right ventricle to pulmonary artery conduits with expanded polytetrafluoroethylene (ePTFE) valves have been reported. The purpose of this study was to evaluate the outcomes of the different material conduits with tricuspid ePTFE valves.

Forty-one consecutive patients who received right ventricle to pulmonary artery conduit with tricuspid ePTFE valves for biventricular repair between April 2004 and December 2016 were studied. The conduits made of autologous pericardial roll or xenograft roll were used in 22 patients (group P) and the conduits made of ePTFE tube were used in 19 patients (group G). The conduit reoperation and the conduit dysfunction were analyzed.

During the median follow-up of 5.8 years, no death related to the conduit was observed. There were four reoperations (three in group P and one in group G). Freedom from conduit reoperation at 5 years was 100% in both groups (P= .30). Freedom from more than moderate conduit stenosis at 5 years after operation was not significantly different between groups (46.9% in group P vs 76.3% in group G, P= .23) even though the group G conduits were significantly smaller and freedom from more than moderate conduit regurgitation at 5 years was significantly better in group G (63.3% in group P vs 94.1% in group G, P= .04).

The conduit with ePTFE valves in the ePTFE tubes had better conduit function compared with the conduit with autologous pericardial or xenograft roll, especially in terms of conduit regurgitation.

Accumulating evidence has demonstrated that polyamines contribute to anti-inflammatory responses by suppressing the expression of proinflammatory cytokines in mononuclear cells and macrophages. However, the effects of polyamines on CD4+ T cell responses remain to be elucidated. Here, we investigated the effect of polyamines on cell fate decisions of naïve CD4+ T cells in vitro. We found that endogenously generated polyamines are essential for the development of T helper 2 (Th2) cells. Treatment with DL-2-difluoromethylornithine (DFMO), an inhibitor of polyamine biosynthesis, diminished GATA3 expression in CD4+ T cells under Th2-skewed conditions. Supplementation of exogenous polyamines rescued GATA3 downregulation caused by DFMO treatment in CD4+ T cells. Transcriptome analysis revealed that deprivation of endogenous polyamines resulted in upregulated Th9-related genes, such as Il9, Irf4, and Batf3, even under the Th2-skewing conditions.
