Morphology of Sinus of Valsalva After Aortic Valve–Sparing Root Replacement Using Valsalva Graft
Publication date: January 2020Source: The Annals of Thoracic Surgery, Volume 109, Issue 1Author(s): Naoki Tadokoro, Yosuke Inoue, Kenji Minatoya, Hitoshi MatsudaUtilization of the Gelweave Valsalva graft (Terumo Vascutek, Tokyo, Japan) for David-type valve-sparing aortic root replacement was still controversial because this prosthesis did not completely reproduce the native sinus of Valsalva. We focused on the morphology of pseudo-Valsalva sinus after the reimplantation procedure and evaluated our novel crimp plication stitch from the viewpoint of morphology of Valsalva sinus at midterm follow-up periods.
To describe our endoscopic aortic valve replacement (E-AVR) technique and to evaluate its early results regardless of the type of prosthetic valve implanted and the patients ’ characteristics. From July 2013 to September 2018, 125 patients (76 males, mean age 68.8±10.9 years, mean EuroScore II 1.51±1.39) underwent isolated E-AVR due to a severe stenosis in 99 cases and insufficiency in 26 cases. The surgical access was a 3-4 cm working port in the second right inter costal space with no-rib spreading and three additional 5 mm mini-ports for the introduction of a 30-degree thoracoscope, the Chitwood clamp and the vent line.
Conclusion: The presence of clinically significant TR is associated with an increase in healthcare utilization and expenditures, irrespective of the presence of HF. PMID: 31952454 [PubMed - as supplied by publisher]
This study sought to derive and validate a systematic method enabling AVC quantification using computed tomography angiography (CTA) in patients with AS.Methods134 consecutive patients with AS who underwent both NCCT and CTA were included in the study and sub-divided into derivation (n=71) and validation cohorts (n=63). On NCCT, AVC was quantified using Agatston method utilizing the software developed for semi-automatic assessment of coronary calcium. On CTA, mean contrast attenuation of aorta (AortaHU) and standard deviation (SD) was measured in the region-of-interest at level of sinotubular junction.ResultsUsing an adjus...
CONCLUSIONS: The incidence and risk factor associations for AKI post TAVR vary by definitions used. Decreased GFR at baseline by both MDRD and CKD-EPI and non-transfemoral approach were associated with an increased risk of AKI post TAVR. PMID: 31941833 [PubMed - as supplied by publisher]
This article will review the most common complications described in literature and focuses on the role of multidetector computed tomography (CT) in their evaluation either exclusively, or complementary to other imaging methods.
ConclusionsMinimally invasive reoperative AVR with a sutureless or rapid-deployment prosthesis is a safe and feasible treatment strategy, resulting in fast recovery and improved postoperative outcome with no mortality and an acceptable complication rate.

Evaluate the safety and efficacy of our modified technique of the extravascular procedure for treating mild to moderately dilated ascending aorta in patients with bicuspid aortic valve (BAV) aortopathy.
Cardiorenal syndrome (CRS) is a group of pathophysiological disorders affecting heart and kidneys.
Abstract BACKGROUND/OBJECTIVES: The increasing complexity of patients undergoing cardiac surgery requires extended myocardial ischaemic periods. Cardiac surgeons demand a cardioplegic solution with prolonged myocardial protection. Therefore, we introduced Custodiol in our centre in 2011. The aim of this study was to investigate the safety and efficacy of Custodiol compared with the standard method of cardioplegia. METHODS: Between 2011 and 2016, 188 adult patients who underwent mitral valve surgery combined with coronary artery bypass grafting were included in this retrospective study. In 113 patients, Custod...
