  • The mechanism and prevention of vein graft failure after coronary artery bypass grafting

    The saphenous vein graft (SVG) is one of the most commonly used graft in coronary artery bypass grafting. However, SVG failure is very common, significantly impacting patient prognosis. Therefore, effectively preventing SVG failure has become an urgent clinical issue and has garnered widespread attention. This article provides a review of research related to SVG failure, aiming to offer insights for clinical diagnosis, treatment and future studies.

  • Treatment of moderate functional mitral regurgitation during aortic valve replacement in patients with aortic valve disease: A retrospective cohort study

    ObjectiveTo evaluate the impact of different surgical strategies for moderate functional mitral regurgitation (FMR) at the time of aortic valve replacement (AVR) on patients' prognosis.MethodsA total of 118 AVR patients, including 84 males and 34 females, aged 58.1±12.4 years, who were complicated with moderate FMR were retrospectively recruited. Patients were divided into three groups according to the treatment strategy of mitral valve: a group A (no intervention, n=11), a group B (mitral valve repair, n=51) and a group C (mitral valve replacement, n=56). The primary endpoint was the early and mid-term survival of the patients, and the secondary endpoint was the improvement of FMR.ResultsThe median follow-up time was 29.5 months. Five patients died perioperatively, all of whom were from the group C. Early postoperative FMR improvement rates in the group A and group B were 90.9% and 94.1% (P=0.694). The mid-term mortality in the three groups were 0.0%, 5.9% and 3.9%, respectively (P=0.264), while the incidences of major cardiovascular and cerebrovascular events were 0.0%, 9.8% and 17.7%, respectively (P=0.230). Improvements of FMR in the group A and group B were 100.0% and 94.3% at the mid-term follow-up (P>0.05).ConclusionFor patients receiving AVR with moderate FMR, conservative treatment or concurrent repair of mitral valve may be more reasonable, while mitral valve replacement may increase the incidence of early and mid-term adverse events.
