Observational StudySingle center experience with the Sorin Bicarbon prosthesis: a 17-year clinical follow-up.
To evaluate the long-term results of aortic valve replacement (AVR) and mitral valve replacement (MVR) with the Sorin Bicarbon prosthesis (SBP). ⋯ The SBP has shown excellent results in terms of clinical improvement and freedom from valve-related complications, even up to 17 years after AVR and MVR. It therefore seems to be a safe option whenever a mechanical prosthesis is needed.

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 StudyValve repair improves the outcome of surgery for chronic severe aortic regurgitation: a propensity score analysis.
For patients with aortic regurgitation (AR), aortic valve (AV) repair represents an attractive alternative to AV replacement (AVR), because it does not expose patients to the risk of prosthetic valve complications. Although the durability of AV repair has been documented, its prognosis has not yet been compared with prognosis of AVR. ⋯ AV repair significantly improves postoperative outcomes in patients with AR and whenever feasible should probably be the preferred mode of surgical correction.

Comparative StudyInfluence of mitral valve repair versus replacement on the development of late functional tricuspid regurgitation.
To study the determinants of functional tricuspid regurgitation (TR) progression after surgical correction of mitral regurgitation, including the influence of mitral valve (MV) repair (MVr) versus replacement (MVR) for degenerative mitral regurgitation. ⋯ The risk of TR progression was low after MVr or MVR for MV prolapse. Timely MV surgery before the development of left atrial dilatation or pulmonary hypertension could further decrease the risk of TR progression during follow-up.
