Why the study?

How does the regional contraction sequence of the left ventricle differ between normal subjects and patients with various myocardial diseases?

Structured PICO

How does the regional contraction sequence of the left ventricle differ between normal subjects and patients with various myocardial diseases?

Population

16 subjects (5 control subjects, 4 patients with mitral insufficiency, 2 with idiopathic hypertrophic subaortic stenosis [IHSS], 2 with idiopathic myocardial hypertrophy, and 3 with myocardial disease with LV dilatation)

Intervention

Cineangiocardiographic analysis (16mm, LAO, 40 frames per sec)

Comparator

Comparison between normal (control) and diseased left ventricles

Outcome

Regional contraction sequence, circumferential shortening velocity (Vcs), and total extent of circumferential shorteningsurrogate

Cineangiocardiography reveals distinct patterns of regional left ventricular contraction asynchrony and altered shortening velocity in various myocardial diseases compared to normal hearts.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

LV contraction patterns may aid disease differentiation; hypothesis-generating for regional analysis, requiring prospective validation.
