Comparative StudyLeft ventricular relaxation in dilated cardiomyopathy: relation to loading conditions and regional nonuniformity.
The purpose of the present study was to investigate how loading conditions and regional nonuniformity affect left ventricular relaxation in dilated cardiomyopathy. ⋯ These results suggest that myocardial relaxation is sensitive to loading conditions and regional nonuniformity in dilated cardiomyopathy and that load reduction can improve both relaxation and systolic performance of the left ventricle.

Comparative StudyBenefits of intraoperative echocardiography in the surgical management of hypertrophic cardiomyopathy.
The purpose of this study was to determine the role of intraoperative echocardiography in planning the site and extent of myectomy and in ensuring adequate control of the left ventricular outflow tract gradient. ⋯ Intraoperative echocardiography proved a useful tool to guide the site and extent of septal myectomy, leading to more adequate surgical resection and to persistence of satisfactory control of the outflow tract obstruction into the early follow-up period.
