Combined subaortic septal myectomy and ALRP is a safe and effective therapy in HOCM patients with significant SAM. ALRP can help prevent residual or recurrent LVOT obstruction and improves mitral regurgitation.

An analysis of three-dimensional movement of the mitral valve annulus (MVA) may address the question of geometrical change after mitral valve repair to preserve mitral annular function. Conventionally, annular contraction has been studied for this purpose. We investigated this geometrical change occurring in the anterior half of the MVA and discuss its clinical significance. Three-dimensional images of the MVA during systole were reconstructed from magnetic resonance images of eight normal subjects. The posterior half of the MVA exhibited translational motion. We assume that this portion, exhibiting translational motion as well as contraction, purely follows the motion of the left ventricular contraction. Compensating for the discrepancy between the motion of the aortic root and that of the posterior half of the MVA, the anterior half exhibited a flexible change in shape during systole, thus maintaining a sufficient left ventricular outflow tract (LVOT). The increase in the extent of displacement of the anterior MVA from the posterior half of the MVA during systole, which was 3.6 +/- 1.0 mm (mean +/- SD), indicates the annular flexibility. The preservation of annular flexibility may prevent LVOT obstruction. Further geometrical analysis of patients after mitral repair will clarify annular function as presented in this article.

Alcoholic patients with intensive suicidal ideation accompanied with alexithymia are characterized by the inability to communicate feelings. Therefore, the possibility of a suicidal attempt in those patients should always be kept in mind even though no suicide message is expressed.

Postoperative prognosis may be worse when preoperative left ventricular ejection fraction is borderline, even if it is within the normal limits. Cardiac evaluation is needed in all patients with carcinoid disease from the earliest time of medical and oncological therapy to improve patient outcome.

Long-term functional outcome of mitral valve repair in children with Shone's anomaly is satisfactory. Repeat MV repair and/or replacement may be deemed necessary during the course of follow-up.
