Mitral valve repair for isolated posterior mitral valve leaflet prolapse: The effect of respect and resect techniques on left ventricular function.
Posterior mitral valve leaflet prolapse repair can be performed by leaflet resection or chordal replacement techniques. The impact of these techniques on left ventricular function remains a topic of debate, considering the presumed better preservation of mitral-ventricular continuity when leaflet resection is avoided. We explored the effect of different posterior mitral valve leaflet repair techniques on postoperative left ventricular function. ⋯ Our study showed that both leaflet resection and chordal replacement repair techniques are effective at preserving postoperative left ventricular function in patients with posterior mitral valve leaflet prolapse and significant regurgitation.

Randomized Controlled TrialA randomized trial comparing axillary versus innominate artery cannulation for aortic arch surgery.
Cerebral protection remains the cornerstone of successful aortic surgery; however, there is no consensus as to the optimal strategy. ⋯ diffusion-weighted magnetic resonance imaging assessments indicate that antegrade cerebral protection with innominate cannulation is safe and affords similar neuroprotection to axillary cannulation during aortic surgery, although the burden of new neurological lesions is high in both groups.

Outcomes of combined aortic and mitral valve replacement with reconstruction of the fibrous skeleton of the heart.
The objectives of this study were to examine operative and long-term results of combined aortic and mitral valve replacement when reconstruction of the fibrous skeleton of the heart is needed because of calcification, abscess, previous operations, or patient-prosthesis mismatch. ⋯ Reconstructions of the fibrous skeleton of the heart are associated with high operative mortality but the long-term results are satisfactory because most patients would not have survived without surgical intervention.
