In SVG lesions, PES are associated with lower rates of angiographic restenosis and target vessel failure than BMS.

During long-term follow-up, use of PES was associated with significantly better clinical outcomes than BMS in SVG lesions. (Stenting of Saphenous Vein Grafts Trial [SOS]; NCT00247208).

The subgroup of POTS patients who can tolerate oral pyridostigmine may demonstrate improvement in their standing HR, standing diastolic blood pressure, and clinical symptoms of orthostatic intolerance.

OBJECTIVESThere are conflicting views regarding the status of valve-sparing root replacement (VSRR) as a proper treatment for acute type A aortic dissection (AAAD). Our goal was to compare the early and late outcomes of VSRR versus those of the Bentall procedure in patients with AAAD.METHODSWe performed a systematic review and meta-analysis of 9 studies to compare the outcomes of VSRR with those of the Bentall procedure in patients with AAAD. We focused on the following issues: early and late mortality rates, re-exploration, thromboembolization/bleeding events, infective endocarditis and reintervention rates.RESULTSA total of 706 patients with AAAD who underwent aortic root surgery were analysed; 254 patients were treated with VSRR and 452 with the Bentall procedure. VSRR was associated with a reduced risk of early death [odds ratio (OR) 0.34; 95% confidence interval (CI) 0.21–0.57] and late death (OR 0.34; 95% CI 0.21–0.57) compared with the Bentall procedure. No statistically significant difference was observed between the VSRR and Bentall groups with pooled ORs (OR 0.77; 95% CI 0.47–1.27, OR 0.61; 95% CI 0.32–1.18 and OR 0.71; 95% CI 0.23–2.15) for re-exploration, thromboembolization/bleeding and postoperative infective endocarditis, respectively. An increased risk of reintervention was observed for the VSRR compared to the Bentall group (OR 3.79; 95% CI 1.27–11.30). The pooled rate of reintervention incidence was 1.6% (95% CI 0.0–3.7%) and 0.4% (95% CI 0.0–1.3%) for the VSRR and the Bentall groups, respectively.CONCLUSIONSVSRR in patients with AAAD can be performed in experienced centres with excellent short- and long-term outcomes compared to those with the Bentall procedure and thus should be recommended especially for active young patients.
