RESUMO
OBJECTIVE: The aim of the study was to compare the prevalence of interventricular and intraventricular asynchrony in patients with different degrees of left ventricular (LV) dysfunction. METHODS: We enrolled 182 patients (male 79%, mean age 64 +/- 11 years) with LV ejection fraction (EF) < 50% and identified two groups: Group A (n = 79) with mild-to-moderate LV dysfunction (EF between 36% and 49%) and Group B (n = 103) with severe dysfunction (EF

The case of a 52-year-old woman with subvalvular aortic stenosis and aortic regurgitation is presented. Mitral regurgitation was associated, due to insertion of two abnormal chordae tendineae at the apex of the anterior papillary muscle and at the free border of the subvalvular membranous annulus. This abnormality displaced the anterior papillary muscle, thus applying a traction at the mitral leaflet. The patient was operated on through a valve-sparing approach, in which the discrete subaortic stenosis was removed through aortotomy and the ectopic chordae were excised. Suture mitral annuloplasty completed the procedure. Aortic and mitral insufficiency almost disappeared at follow-up. From the examination of this case and from a review of pertinent literature it emerges that in event of similar complex congenital abnormalities without intrinsic valve disease, a conservative approach should be chosen so that valve replacement can be avoided.

BACKGROUND: In non-Asiatic population, apical hypertrophic cardiomyopathy represents 1% to 2% of hypertrophic cardiomyopathies. The presence of an apical ventricular aneurysm occurs in 1% of patients with the apical variant of hypertrophic cardiomyopathy. METHODS AND RESULTS: We present two patients with hypertrophic cardiomyopathy, both illustrating an early diastolic paradoxic jet flow between the apex and the middle area of ventricle. Such paradoxic flow is possibly due to the coexistence of mid-chamber obliteration and segmental wall motion abnormalities at the apex. The incidence and clinical significance of this flow pattern is still to be clarified.
