TEVAR With Supra-Aortic Trunk Revascularization Is Associated With Increased Risk Of Periprocedural Ischemic Stroke
Ischemic stroke is a devastating complication of thoracic endovascular aortic repair (TEVAR). This risk may be higher in more proximal aneurysms that require arch manipulation. The purpose of this study was to (1) describe 30-day stroke and death rates in patients undergoing TEVAR, (2) compare stroke rates in patients undergoing TEVAR for arch versus descending aneurysm pathology, and (3) identify predictive factors associated with stroke after TEVAR.

Retrograde arterial perfusion and its outcome in robotic mitral valve surgery
CONCLUSION: Retrograde arterial perfusion is a safe method for minimally invasive cardiac surgery less than 3.5 hours under mild hypothermic status.PMID:34840044 | DOI:10.1016/j.asjsur.2021.10.013

Long-term Outcomes of Concomitant Surgical Ablation for Atrial Fibrillation
CONCLUSIONS: Concomitant atrial fibrillation ablation during cardiac surgery is safe, does not increase the rate of perioperative complications, and confers the benefit of long-term survival after cardiac surgery in adults. Atrial fibrillation ablation also improved cardiac surgery patients' long-term survival compared with the matched general atrial fibrillation population.PMID:36216085 | DOI:10.1016/j.athoracsur.2022.09.036

Assistive technology using regurgitation fraction and fractional-order integration to assess pulmonary valve insufficiency for pre-surgery decision making and post-surgery outcome evaluation
This study proposes an assistive technology to quantify regurgitation using the regurgitation fraction (RF) and heart pump efficiency (HPE). In signal preprocessing stage, the detrending and zero-crossing processes are used to remove the unwanted flow fluctuations and identify the end-systolic and end-diastolic periods per each cardiac cycle. The fractional-order integrations are employed to calculate the stroke volume (SV) and regurgitation volume (RV). Then, the regurgitation flow can be quantified that indicates the high correlation with HPE. For a mimicking pulmonary circulation loop system, the proposed screening mode...
