Capturing echocardiographic allograft valve function over time after allograft aortic valve or root replacement.
This study describes echocardiographic allograft valve function over time in a cohort of patients who were prospectively followed after allograft aortic valve or root replacement, illustrating the use of longitudinal data analysis for assessing valve function over time. ⋯ Both aortic regurgitation and stenosis increase over time after allograft aortic valve or root replacement. Younger patient age and use of the subcoronary implantation technique are associated with increased regurgitation and stenosis. The use of nonlinear longitudinal models allows for an insightful analysis of allograft valve function over time.

Comparative StudyComparison of early hemodynamic performance of 3 aortic valve bioprostheses.
The study objective was to determine whether the new-generation Trifecta (St Jude Medical Inc, St Paul, Minn) bovine aortic valve bioprosthesis, which is designed for supra-annular positioning, produces early postoperative hemodynamic results comparable to or better than those of the Mitroflow (Sorin Group, Milan, Italy) or Perimount Magna (Edwards Lifesciences Corp, Irvine, Calif) bovine aortic valve bioprostheses. ⋯ Early hemodynamic postoperative performance of the Trifecta bioprosthesis is favorable. Additional follow-up should determine whether these small hemodynamic differences will persist and influence later clinical outcomes.

Comparative StudyPrevious coronary stents do not increase early and long-term adverse outcomes in patients undergoing off-pump coronary artery bypass grafting: a propensity-matched comparison.
The aim of our study was to compare the early and long-term outcomes of patients undergoing off-pump coronary artery bypass grafting (CABG) with and without previous coronary stents. ⋯ Previous coronary stents do not increase early and long-term morbidity or mortality in patients undergoing off-pump CABG.

Multicenter StudyChronic competitive flow from a patent arterial or venous graft to the circumflex system does not impair the long-term patency of internal thoracic artery to left anterior descending grafts in patients with isolated predivisional left main disease: long-term angiographic results of 2 different revascularization strategies.
To compare 2 different surgical approaches to treatment of patients with isolated predivisional stenosis of the left main coronary artery (IOSLM) and to evaluate the effect of chronic competitive flow from a patent arterial or venous graft to the circumflex system on the long-term patency of internal thoracic artery (ITA) to left anterior descending grafts. ⋯ In patients with IOSLM, long-term ITA to left anterior descending artery patency is not jeopardized by chronic flow competition from a concomitant arterial or venous graft to the circumflex system. Notably, the addition of a second ITA graft or of a SV to the first ITA does not lead to differences in long-term angiographic patency. Our results minimize the role of flow competition in this setting and should be kept in mind when choosing the appropriate graft configuration.

Comparative StudyEarly and midterm outcomes of hemiarch replacement combined with stented elephant trunk in the management of acute DeBakey type I aortic dissection: comparison with total arch replacement.
For patients with acute DeBakey type I aortic dissection without an intimal tear in the arch, the early and midterm outcomes of hemiarch replacement with stented elephant trunk were compared with those of total arch replacement. ⋯ For patients with acute DeBakey type I dissection without an intimal tear in the arch, hemiarch replacement with stented elephant trunk implantation was easily performed, with satisfactory early and midterm outcomes. For these selective patients, total arch replacement with the stented elephant trunk technique did not improve the late surgical results further.
