A mid- and long-team follow-up study of the application of single-valved bovine pericardium patches in right ventricular outflow tract reconstruction.

Background: Pulmonary regurgitation following right ventricular outflow tract (RVOT) reconstruction may cause right heart dysfunction and even right heart failure. Installation of a single valve at this time point can effectively reduce pulmonary regurgitation, thereby protecting right heart function. Here, we analyzed the outcomes and mid- and long-term follow-up data of patients undergoing single-valved bovine pericardium patch (svBPP) placement for reconstruction and explored the effectiveness and gaps of svBPP in preventing right heart failure.

Monkeypox outbreaks in the context of the COVID-19 pandemic: Network and clustering analyses of global risks and modified SEIR prediction of epidemic trends.

Background: Ninety-eight percent of documented cases of the zoonotic disease human monkeypox (MPX) were reported after 2001, with especially dramatic global spread in 2022. This longitudinal study aimed to assess spatiotemporal risk factors of MPX infection and predict global epidemiological trends.

Method: Twenty-one potential risk factors were evaluated by correlation-based network analysis and multivariate regression.

The V-shaped double-layer patch technique for complete atrioventricular septal defect: A novel surgical technique.

Objective: Several surgical techniques for repair of a complete atrioventricular septal defect have been developed. However, the postoperative complications with these methods may lead to reoperation during follow-up. The aim of this report is to share our experience with a modified surgical technique for complete atrioventricular septal defect that has anatomic advantages postoperatively and could reduce the reoperation rate.

Descending aorta translocation for bronchial stenosis caused by shorter interaortic distance.

Background And Aim Of The Study: Numerous anatomic relationships of arteries could cause extrinsic compression of the trachea or bronchus. We report a rare left bronchial stenosis just caused by shorter inter-aortic distance.

Methods: One patient wih recurrent coughing and wheezing was diagnosed as left emphysema.

Cardiac-specific methylation patterns of circulating DNA for identification of cardiomyocyte death.

Background: Correct detection of human cardiomyocyte death is essential for definitive diagnosis and appropriate management of cardiovascular diseases. Although current strategies have proven utility in clinical cardiology, they have some limitations. Our aim was to develop a new approach to monitor myocardial death using methylation patterns of circulating cell-free DNA (cf-DNA).

[Genetics and pedigree analysis of primary carnitine deficiency cardiomyopathy in 6 cases].

Objective: To investigate the mutation and background of SLC22A5 in 6 patients with primary carnitine deficiency (PCD) who only presented as cardiomyopathy.

Method: Genomic DNA were abstracted from the blood of the patients and their parents. Using high-throughput sequencing to determine the mutation site.
