A novel and simple technique for correction of posterior leaflet prolapse due to chordal elongation or rupture.
The study objective was to evaluate the midterm results of a technique for correction of posterior leaflet prolapse without resection or use of artificial chordae. ⋯ Although the rationale for the use of the U technique is different from what is generally accepted, the midterm results of this approach are comparable to those obtained with more conventional techniques, remaining stable after a mean follow-up of 18 months.

Anatomic repair of Ebstein's anomaly with isolated anterior leaflet downward displacement.
Ebstein's anomaly with isolated anterior leaflet downward displacement is rare and has not been reported in the literature to our knowledge. In this article, our experience of the surgical treatment in 6 cases with this anomaly is reported. ⋯ Ebstein's anomaly with isolated anterior leaflet downward displacement is a complex and severe abnormality, and has several unique anatomic and clinical features and specific surgical requirements. Preoperative diagnosis can be made by clinical investigation and echocardiography. Excellent results can be achieved by anatomic correction.

Fate of functional tricuspid regurgitation in aortic stenosis after aortic valve replacement.
Functional tricuspid regurgitation (TR) is found not infrequently in conjunction with aortic stenosis. The aim of the present study was to evaluate the changes in TR and to identify the predictors of late progression after aortic valve replacement. ⋯ Not only did TR in patients with aortic stenosis frequently persist after aortic valve replacement, it was progressive in some. This finding was associated with left ventricular diastolic dysfunction. A concomitant tricuspid valve procedure could be considered in selected patients with aortic stenosis to avoid late TR.

Clinical significance and determinants of the universal definition of perioperative bleeding classification in patients undergoing coronary artery bypass surgery.
We evaluated the clinical significance and identified the predictors of the universal definition of perioperative bleeding (UDPB) classes in patients undergoing isolated coronary artery bypass grafting (CABG). ⋯ High UDPB classes were associated with significantly poorer immediate and late outcomes. The UDPB classification seems to be a valuable research tool to estimate the severity of bleeding and its prognostic impact affect after coronary surgery.

Observational StudyLong-term outcomes after elective isolated mechanical aortic valve replacement in young adults.
The aim of this study was to determine long-term survival and clinical outcomes after elective isolated mechanical aortic valve replacement in young adults. ⋯ In young adults undergoing elective isolated mechanical AVR, survival remains suboptimal compared with an age- and gender-matched general population. Furthermore, there is a low but constant hazard of prosthetic valve reintervention after mechanical AVR.
