AI Article Synopsis

  • Mediastinitis following synthetic vascular replacement surgery for thoracic aortic diseases can lead to poor outcomes.
  • A Bentall procedure was repeated to address an aortic root pseudoaneurysm that arose after treating the initial surgery's mediastinitis.
  • Using a rectus abdominis muscle flap has shown effectiveness in managing mediastinitis infections following heart surgery, but potential complications like hemorrhages and pseudoaneurysms should be monitored after such high-risk procedures.

Article Abstract

The occurrence of mediastinitis following synthetic vascular replacement surgery is still associated with an unfavorable prognosis in the treatment of thoracic aortic diseases. This time we report a Bentall procedure that we re-performed to treat an aortic root pseudoaneurysm, which developed after a postoperative mediastinitis. This followed the first Bentall procedure, which was treated by debridement of the focus of infection, continuous lavage, and a two-step rectus abdominis muscle flap implantation. Implantation of a rectus abdominis muscle flap is effective in controlling infection in the treatment of mediastinitis after heart surgery. However, after synthetic vascular replacement surgeries have been performed to treat aortic diseases, especially after aortic root reconstruction surgery, which puts stress on the anastomotic site, consideration should be given regarding the development of hemorrhages and pseudoaneurysms as a result of infection-induced tissue fragilization.

Extensive congenital pulmonary airway malformation (CPAM) of the left fetal lung and associated marked dextroposition of the fetal heart were noted at 21 weeks' gestation. The right fetal lung appeared compressed with the cardiomediastinal shift angle measuring approximately 20 degrees. Potential subsequent right pulmonary hypoplasia was considered.

Aims: To assess the reproducibility of 4D-Flow cardiac magnetic resonance (CMR) parameters in the descending thoracic aorta-DTAo-(regurgitant fraction [RF], end-diastolic reverse flow [EDRF], and holodiastolic flow reversal [HDR]), and the relationship with RF in the sinotubular junction (STJ), and the left ventricular end-diastolic volume index (LVEDVI) in patients with chronic aortic regurgitation (AR).

Methods And Results: A descriptive study of these variables was conducted. A receiver operating characteristic curve was used to determine the optimal cut-off point.

Acute coronary occlusion during transcatheter aortic valve implantation (TAVI) is an unwarranted complication associated with high mortality. The current TAVI practices recommend a multidetector computed tomography (MDCT) evaluation of the aortic valve, the left ventricular outflow tract, and the aortic root to determine the conventional risk factors for coronary obstruction like low-lying coronary ostia and narrow sinuses of Valsalva, mandating prophylactic coronary protection or native valve leaflet modification in high-risk patients. Despite optimal anatomy, acute coronary occlusion can still occur due to multiple mechanisms, one of which is coronary embolism due to thrombus, calcium, or native aortic valve fragments.

Background: The aim of this study was to investigate whether the hybrid technique yields superior outcomes in comparison with the total arch replacement combined with frozen elephant trunk (TAR + FET) for acute aortic dissection (AAD) involving the aortic arch.

Methods: This retrospective cohort study using propensity-score matching included patients with AAD involving the aortic arch admitted to Nanjing First Hospital and Shanghai General Hospital from January 2015 to June 2020. The in-hospital and mid-term outcomes were compared between patients who received hybrid treatment (n = 136) and those who received TAR + FET (n = 415).

In the context of dynamic image-based computational fluid dynamics (DIB-CFD) modeling of cardiac system, the role of sub-valvular apparatus (chordae tendineae and papillary muscles) and the effects of different mitral valve (MV) opening/closure dynamics, have not been systemically determined. To provide a partial filling of this gap, in this study we performed DIB-CFD numerical experiments in the left ventricle, left atrium and aortic root, with the aim of highlighting the influence on the numerical results of two specific modeling scenarios: (i) the presence of the sub-valvular apparatus, consisting of chordae tendineae and papillary muscles; (ii) different MV dynamics models accounting for different use of leaflet reconstruction from imaging. This is performed for one healthy subject and one patient with mitral valve regurgitation.
