Background: This purpose of this study was to evaluate the impact of proximal vs extensive repair on mortality and how this impact is influenced by patient characteristics.
Methods: Of 5510 patients with acute type A aortic dissection from 13 Chinese hospitals (2016-2021) categorized by proximal vs extensive repair, 4038 patients were used for for model derivation using eXtreme gradient boosting and 1472 patients for model validation.
Results: Operative mortality of extensive repair was higher than proximal repair (10.
Background: Risk factors for healthcare associated infections (HAIs) following surgical repair of acute type A aortic dissection (TAAD) has not been well defined.
Methods: This was a retrospective study of patients treated between Jan 2013 and May 2016 at the large tertiary teaching hospital in Jiangsu, China. Logistic regression analysis was performed to investigate the association patients with acute TAAD who underwent ascending aortic and arch replacement under deep hypothermic circulatory arrest (DHCA) and healthcare associated infections during hospitalization.
The surgical treatment for aortic diseases remains a challenge for any cardiac surgeon. The use of sutureless ring connector in aortic anastomosis can simplify the procedure and shorten anastomosis time. Therefore, we developed a novel device for sutureless aortic anastomosis.

We aimed to determine the association of obstructive sleep apnea (OSA) and central sleep apnea (CSA) with perioperative events in CVR surgery in patients with rheumatic valvular heart disease (RVHD).
Methods: Between April 2010 and April 2014, 290 patients with RVHD undergoing CVR were screened for sleep apnea 1 to 7 days before CVR.
Objective: To investigate the characteristics of baseline body fluid content and overnight fluid shifts between non-obstructive sleep apnea (non-OSA) and obstructive sleep apnea (OSA) subjects.
Methods: A case-controlled study was performed between February 2013 and January 2014, with 36 (18 OSA and 18 non-OSA) outpatients enrolled in this study. Polysomnographic parameters and results of body fluid were compared between the two groups.
Article Synopsis
- Atrial fibrillation (AF) is a common heart rhythm disorder, and this study investigates the role of transcription factors NF-AT3 and NF-AT4 in atrial structural changes associated with AF and their relationship with collagen biomarkers.
- Right and left atrial samples from 90 patients undergoing valve replacement surgery were analyzed, measuring the expression of NF-AT3, NF-AT4, and collagen types I and III, alongside serum levels of specific collagen-related markers.
- The findings indicate that NF-AT3 and NF-AT4 are elevated in AF patients, particularly in the left atrium, suggesting they are involved in the structural remodeling of the heart, and highlighting PICP and TGF-β1 as potential serum biomarkers for
Background: Recent studies have suggested that cardiac surgery may affect sleep-disordered breathing (SDB) in chronic heart failure patients. However, the dynamic changes in sleep apnea and heart function after cardiac surgery and the mechanisms responsible for these changes remain unknown.
Methods: Patients with rheumatic valvular heart disease (RVHD) and SDB were enrolled and followed up at three, six and 12 months after cardiac valve replacement (CVR).
The recent article entitled "Principles of biopsy in suspected lung cancer: priority still based on invasion in the era of targeted therapy?" published in Journal of Thoracic Disease by Chen et al., concluded the principles of biopsy in suspected lung cancer should be prioritized in sequence based on weight in clinical management, acquisition of tissue, invasion, efficiency and cost. We reported a patient with a 30-year history of pulmonary silicosis, had been found no evidence of tumor after receiving a series of invasive examinations.

This study was designed to determine the prevalence, characteristics, and risk factors for SDB in RVHD patients.
Methods: A cross-sectional study was conducted in 260 RVHD patients.
