lications and also financial expenses of the procedure. We believe that this method is suitable and easiest for nodules located less than 6 cm from the anal verge because of possible complications with angulation of linear stapler.Since the development of balloon angioplasty and balloon-expandable endovascular stent technology in the 1970s and 1980s, percutaneous transcatheter intervention has emerged as a mainstay of therapy for congenital heart disease (CHD) lesions throughout the systemic and pulmonary vascular beds. Congenital lesions of the great vessels, including the aorta, pulmonary arteries, and patent ductus arteriosus, are each amenable to transcatheter intervention throughout the lifespan, from neonate to adult. In many cases, on-label devices now exist to facilitate these therapies. In this review, we seek to describe the contemporary approach to and outcomes from transcatheter management of major CHD lesions of the great vessels, with a focus on coarctation of the aorta, single- or multiple-branch pulmonary artery stenoses, and persistent patent ductus arteriosus. We further comment on the future of transcatheter therapies for these CHD lesions.Transcatheter balloon valvuloplasty for the treatment of aortic and pulmonary valve stenosis was first described nearly 40 years ago. Since that time, the technique has been refined in an effort to optimize acute outcomes while reducing the long-term need for reintervention and valve replacement. Balloon pulmonary valvuloplasty is considered first-line therapy for pulmonary valve stenosis and generally results in successful relief of valvar obstruction. Larger balloon to annulus (BAR) diameter ratios can increase the risk for significant valvar regurgitation. However, the development of regurgitation resulting in right ventricular dilation and dysfunction necessitating pulmonary valve replacement is uncommon in long-term follow-up. Balloon aortic valvuloplasty has generally been the first-line therapy for aortic valve stenosis, although some contemporary studies have documented improved outcomes following surgical valvuloplasty in a subset of patients who achieve tri-leaflet valve morphology following surgical repair. Over time, progressive aortic regurgitation is common and frequently results in the need for aortic valve replacement. Neonates with critical aortic valve stenosis remain a particularly high-risk group. More contemporary data suggest that acutely achieving an aortic valve gradient less then 35 mm Hg with mild aortic regurgitation may improve long-term valve performance and reduce the need for valve replacement. Continued study will help to further improve outcomes and reduce the need for future reinterventions.
Post-operative atrial fibrillation (POAF) is associated with worse long-term cardiovascular outcomes.
This study hypothesized that injecting calcium chloride (CaCl
) into the major atrial ganglionated plexi (GPs) during isolated coronary artery bypass grafting (CABG) can reduce the incidence of POAF by calcium-induced autonomic neurotoxicity.
This proof-of-concept study randomized 200 patients undergoing isolated, off-pump CABG to CaCl
(n=100) or sodium chloride (sham, n=100) injection. Two milliliters of CaCl
(5%) or sodium chloride (0.9%) was injected into the 4 major atrial GPs during CABG. All patients received 7-day continuous telemetry and Holter monitoring. The primary outcome was incidence of POAF (≥30 s) in 7days. Secondary outcomes included length of hospitalization, POAF burden, average ventricular rate during AF, plasma level of inflammatory markers, and actionable antiarrhythmic therapy to treat POAF.
The POAF incidence was reduced from 36% to 15% (hazard ratio 0.366; 95% confidence rvation Prevents Postoperative Atrial Fibrillation; ChiCTR1800019276).
Previously, observational studies have identified associations between higher levels of dietary-derived antioxidants and lower risk of coronary heart disease (CHD), whereas randomized clinical trials showed no reduction in CHD risk following antioxidant supplementation.
The purpose of this study was to investigate possible causal associations between dietary-derived circulating antioxidants and primary CHD risk using 2-sample Mendelian randomization (MR).
Single-nucleotide polymorphisms for circulating antioxidants (vitamins E and C, retinol, β-carotene, and lycopene), assessed as absolute levels and metabolites, were retrieved from the published data and were used as genetic instrumental variables. Summary statistics for gene-CHD associations were obtained from 3 databases the CARDIoGRAMplusC4D consortium (60,801 cases; 123,504 control subjects), UK Biobank (25,306 cases; 462,011 control subjects), and FinnGen study (7,123 cases; 89,376 control subjects). For each exposure, MR analyses were performed pantioxidant levels on CHD risk. Therefore, it is unlikely that taking antioxidants to increase blood antioxidants levels will have a clinical benefit for the prevention of primary CHD.
The “gray zone” of myocardial fibrosis (GZF) on cardiovascular magnetic resonance may be a substrate for ventricular arrhythmias (VAs).
The purpose of this study was to determine whether GZF predicts sudden cardiac death (SCD) and VAs (ventricular fibrillation or sustained ventricular tachycardia) in patients with coronary artery disease (CAD) and a wide range of left ventricular ejection fractions (LVEFs).
In this retrospective study of CAD patients, the presence of myocardial fibrosis on visual assessment (MF
) and GZF mass in patients with MF
were assessed in relation to SCD and the composite, arrhythmic endpoint of SCD or VAs.
Among 979 patients (mean age [± SD] 65.8 ± 12.3 years), 29 (2.96%) experienced SCD and 80 (8.17%) met the arrhythmic endpoint over median 5.82 years (interquartile range 4.1 to 7.3 years). In the whole cohort, MF
was strongly associated with SCD (hazard ratio 10.1; 95% confidence interval [CI] 1.42 to 1,278.9) and the arrhythmic endpoint (hazard ratio 28.0; 95%CI 4.07 tssment of MFVA followed by quantification of GZF3SD mass may be preferable to LVEF.
The association of age with the outcomes of bilateral internal thoracic arteries (BITAs) versus single internal thoracic arteries (SITAs) for coronary bypass grafting (CABG) remains to be determined.
The purpose of this study was to evaluate the association between age and BITA versus SITA outcomes in the Arterial Revascularization Trial.
The primary endpoints were all-cause mortality and a composite of major adverse events, including all-cause mortality, myocardial infarction, or stroke. Secondary endpoints were bleeding complications and sternal wound complications up to 6months after surgery. Multivariable fractional polynomials analysis and log-rank tests were used.
Age did not affect any of the explored outcomes in the overall BITA versus SITA comparison in the intention-to-treat analysis and in the analysis based on the number of arterial grafts received. HygromycinB However, when the intention-to-treat analysis was restricted to the populations of patients between age 50 and 70 years, younger patients in the BITA arm had a significantly lower incidence of major adverse events (p=0.
