Background: Aortic regurgitation (AR) related to Behcet's disease (BD) is rare, but usually fatal. Perivalvular leakage (PVL) is high if AR related to BD treated with regular AVR. In this study, we report the surgical management of AR secondary to BD.

Objective: To determine whether different changes of pulmonary artery systolic pressure (PASP) after surgeries have an impact on the long-term outcomes in patients with rheumatic and degenerative mitral valve (MV) disease and atrial fibrillation.

Methods: Between 2004 and 2016, 1,188 patients with rheumatic and degenerative MV disease undergoing MV and Cox-Maze procedure were identified. Clinic outcomes, as well as rhythm state and echocardiography indices in long-term follow-up were recorded.

Article Synopsis
  • Commuters near roads face significant traffic-related pollution, and the role of vegetation in mitigating this pollution is complex.
  • A study measured the impact of three vegetation types - dense, porous, and clearing - on air quality, finding that dense vegetation can lead to higher pollutant concentrations on nearby sidewalks and bikeways due to particle accumulation.
  • While dense vegetation acts as a barrier to pollutants and can improve air quality at a distance, it may actually worsen air quality in its immediate vicinity, indicating both positive and negative effects of roadside greenery.

Several novel technological developments and surgical approaches have characterized the field of aortic surgery in the recent decade. The progressive introduction of endovascular procedures, minimally invasive surgical techniques and hybrid approaches have changed the practice in aortic surgery and generated new trends and questions. Also, the advancements in the manufacturing of tissue engineered vascular grafts as substitutes for aortic replacements are enlightening new avenues in the treatment of aortic disease.

Article Synopsis
  • Acute aorta dissection (AD) is a serious emergency affecting mostly young adults under 45, with a study of 490 patients in China showing a median age of 38, predominantly young men, and high rates of smoking and hypertension.
  • The most common symptom was sudden chest or back pain, and the majority of patients underwent surgical treatment, though a small number experienced serious complications during the perioperative period.
  • The study found that longer cardiopulmonary bypass times and a history of previous heart surgeries were linked to higher rates of surgery-related complications and mortality, highlighting the importance of these factors in managing acute AD.

Objective: To analyze the clinical outcome of corticosteroid and/or immunosuppressive treatment preoperatively in patients with Takayasu's arteritis.

Patients And Methods: Forty-six patients with Takayasu's arteritis who received cardiovascular surgery between January 2010 and December 2015 in Beijing Anzhen Hospital were enrolled in this study. Their clinical characteristics, preoperative drug therapy, surgical treatment, and pathological examination results were retrospectively analyzed for the effect of drugs on outcome of the surgery.

Background: The surgical treatment of Crawford extent II aneurysms after thoracic endovascular aortic repair (TEVAR) remains challenging, because of the need to remove the failed endograft and the complexity of the aortic reconstruction. We retrospectively reviewed our experience with surgical management of Crawford extent II aneurysms after TEVAR using thoracoabdominal aortic replacement (TAAR).

Methods: Eleven patients (10 males, 1 female) with Crawford extent II aneurysm after TEVAR were treated with TAAR between August 2012 and May 2015.

The molecular mechanism and signal transduction pathways involved in urothelial cancer (UC) after renal transplantation (RTx) remain unknown. In this study, we investigated the profiling of messenger RNA (mRNA) and long non-coding RNA (lncRNA) in RTx recipients with UC. The mRNA and lncRNA of six pairs of UC and corresponding normal urothelial tissues in RTx recipients were profiled using Arraystar Human lncRNA Microarray V3.

A new phenyl glycoside, 2-(sophorosyl)-1-(4-hydroxyphenyl)ethanone (9), was isolated from the ethanolic extract of the aerial parts of Equisetum hyemale L., together with eight known compounds (1-8). The structures of these compounds were elucidated using a combination of spectroscopic analyses and chemical method.

Objective: To evaluate the therapeutic effects of mitral valve repair for the treatment of the anterior leaflet prolapse of mitral valve.

Methods: From November 1998 to October 2007, 210 patients with severe anterior leaflet prolapse of mitral valve underwent valve repair. The condition of valve was preoperative, intraoperative, and postoperative assessed with echocardiography.
