Initial clinical manifestations and mid- and long-term results after surgical repair of double-chambered right ventricle in children and adults.

Objective: By means of retrospective analysis of our institutional experience, we reviewed the clinical manifestation and outcomes of patients subsequent to surgical repair of double-chambered right ventricle.

Methods: Between 1988 and 2005, we performed surgical repair in 35 of 37 patients diagnosed with double-chambered right ventricle. The patients ranged in age from 4 to 69 years, with a mean of 21.

Assessment of regional atrial function in patients with hypertrophic cardiomyopathies using tissue Doppler imaging.

Background: This study applied tissue Doppler imaging and color tissue Doppler imaging to study atrial function changes in patients with hypertrophic cardiomyopathy (HCM). The profile of the segmental atrial velocities and the strain rate were determined and compared with those of normal matched control subjects.

Methods: This study investigated 20 patients with HCM and 20 age-matched healthy control subjects.
