Why the study?

Can echocardiography accurately recognize and measure mitral-semilunar valve discontinuity compared to angiography in patients with complex congenital malformations?

Population

5 cases where both great vessels originated from the right ventricle (complex congenital malformations)

Comparison

Echocardiography vs Angiography

Implication

May support echocardiography for valve discontinuity assessment in congenital disease; leaves open larger validation studies.

Key Points

Determine whether noninvasive echocardiography can identify mitral-semilunar valve discontinuity to detect the origin of both great vessels from the right ventricle.
Examined echocardiographic and angiographic recordings across cases with normal and transposed great-vessel relationships, including N=5 cases with both great vessels originating from the right ventricle.
Evaluated systolic echo continuity and depth between the mitral valve and the posterior margins of the adjacent great vessel.
Echocardiography identified mitral-semilunar valve discontinuity in all five cases where both great vessels arose from the right ventricle, showing the adjacent vessel's posterior border lying anterior to the mitral echo.
Measurements of anatomical valve separation obtained by ultrasound were virtually identical to those measured on invasive angiograms.

Structured PICO

Can echocardiography accurately recognize and measure mitral-semilunar valve discontinuity compared to angiography in patients with complex congenital malformations?

Population

5 cases where both great vessels originated from the right ventricle (complex congenital malformations)

Intervention

Echocardiography

Comparator

Angiography

Outcome

Recognition and measurement of mitral-semilunar valve discontinuitysurrogate

Echocardiography is a valuable, atraumatic adjunct to angiography for evaluating mitral-semilunar valve relationships in complex congenital heart disease.
