Fifteen-Year Outcomes After Valve-Sparing Aortic Root Remodelling or Exclusion of the Non-Coronary Sinus: When to Preserve the Sinuses of Valsalva?

Background: Isolated exclusion of the non-coronary sinus (NCS) is an attractive strategy in valve-sparing aortic root surgery, which avoids the mobilisation and re-implantation of coronary ostia. However, the long-term durability of aortic valve repair and the fate of remnant sinuses of Valsalva remain unclear.

Method: From January 2006 to December 2013, 29 patients underwent replacement of the ascending aorta extending to the NCS (group NCS) and 56 patients underwent a modified Yacoub procedure (group MY) in our centre by a single surgeon.

Fifteen-Year Outcomes Following Valve-Sparing Aortic Root Replacement in Elderly Patients.

Background: Valve-sparing aortic root replacement (VSRR) techniques have several advantages such as preservation of physiological haemodynamics of the native aortic valve and avoidance of prosthetic valve-related complications. However, VSRR procedures are generally performed in young patients and the long-term results in elderly patients (≥65 years) are scarce.

Methods: Fifty-six (56) consecutive patients underwent VSRR surgery by a single surgeon at the current centre between January 2006 and December 2013; a modified "remodelling technique" was typically performed.

Isolated tricuspid valve surgery after congenital versus left heart-disease surgery: mid-term outcomes.

Background: Left heart involvement might be a differential factor in the physiopathology and prognosis of severe tricuspid regurgitation (TR) following cardiac surgery. We aimed to compare the outcomes of isolated tricuspid valve surgery (ITVS) after congenital versus left heart-disease surgery.

Methods: We retrospectively studied and followed up 58 patients who underwent ITVS for TR following cardiac surgery in our center from January 2012 to December 2017.

Classical and next generation sequencing approaches unravel Bymovirus diversity in barley crops in France.

Despite the generalized use of cultivars carrying the rym4 resistance gene, the impact of viral mosaic diseases on winter barleys increased in recent years in France. This change could reflect i) an increased prevalence of the rym4 resistance-breaking pathotype of Barley yellow mosaic virus Y (BaYMV-2), ii) the emergence of rym4 resistance-breaking pathotypes of Barley mild mosaic virus (BaMMV) or iii) the emergence of other viruses. A study was undertaken to determine the distribution and diversity of viruses causing yellow mosaic disease.

Bilateral unilateral internal mammary revascularization in patients with left ventricular dysfunction.

Aim: To investigate the survival benefit of bilateral internal mammary artery (BIMA) grafts in patients with left ventricular dysfunction.

Methods: Between 1996 and 2009, we performed elective, isolated, primary, multiple cardiac arterial bypass grafting in 430 consecutive patients with left ventricular ejection fraction ≤ 40%. The early and long-term results were compared between 167 patients undergoing BIMA grafting and 263 patients using left internal mammary artery (LIMA)-saphenous venous grafting (SVG).
