Impact of mitral annular calcification on cardiovascular events in a multiethnic community: the Northern Manhattan Study.
We sought to determine the magnitude of the association between mitral annular calcification (MAC) and vascular events in a multiethnic cohort. ⋯ In this multiethnic cohort, MAC was a strong and independent predictor of cardiovascular events, especially MI and VD. The risk increase was directly related to MAC severity.

Comparative StudyComparison of vascular response after sirolimus-eluting stent implantation between patients with unstable and stable angina pectoris: a serial optical coherence tomography study.
The aim of the present study was to compare lesion morphologies after sirolimus-eluting stent (SES) implantation between patients with unstable angina pectoris (UAP) and stable angina pectoris (SAP) with the use of optical coherence tomography (OCT). ⋯ Serial OCT examinations demonstrated markedly different vascular response up to 9 months after SES implantation between UAP and SAP patients. Although the inadequate lesion morphologies after stenting were observed more frequently in UAP patients, these findings were not associated with adverse outcomes in patients with antiplatelet therapy.

Comparative StudySafety and accuracy of 64-slice computed tomography coronary angiography in children after the arterial switch operation for transposition of the great arteries.
We investigated the accuracy of 64-slice computed tomography (CT) angiography, as compared to invasive angiography, to evaluate reimplanted coronary arteries in children after arterial switch operation (ASO) for transposition of the great arteries (TGA). ⋯ 64-slice CT coronary angiography performs as well as invasive angiography for detecting significant coronary lesions in the majority of children who have undergone the arterial switch procedure for TGA. CT also provides information on the underlying mechanism of coronary luminal narrowing.

Multicenter StudyOutcomes in mitral regurgitation due to flail leaflets a multicenter European study.
The purpose of this study was to assess incidence and predictors of events associated with nonsurgical and surgical management of severe mitral regurgitation (MR) in European institutions. ⋯ In this multicenter study, nonsurgical management of severe MR was associated with notable rates of adverse events. Surgery especially MV repair performed during follow-up was beneficial in reducing rates of cardiac events. These findings support surgical consideration in patients with MR due to flail leaflets for whom MV repair is feasible.
