Why the study?

Does the AM/TM ratio assessed by M-mode echocardiography accurately differentiate between normal and pseudonormal mitral inflow in patients with E/A >1?

Population

71 patients with a ratio of early to late mitral flow >1 undergoing cardiac catheterization and…

Implication

May support AM/TM ratio for pseudonormal inflow detection; leaves open prospective validation before clinical adoption.

Structured PICO

Does the AM/TM ratio assessed by M-mode echocardiography accurately differentiate between normal and pseudonormal mitral inflow in patients with E/A >1?

Population

71 patients with a ratio of early (E) to late mitral flow (A) >1 undergoing cardiac catheterization and echocardiography

Intervention

M-mode echocardiography assessment of left atrial wall motion (specifically AM/TM ratio)

Comparator

Patients with normal LVEDP (< 15 mmHg) vs pseudonormal LVEDP (≥ 15 mmHg)

Outcome

Diagnostic accuracy (sensitivity, specificity, PPV, NPV) of AM/TM ratio >0.5 for detecting pseudonormalization (LVEDP ≥ 15 mmHg)surrogate

The AM/TM ratio derived from M-mode echocardiography is a highly specific and sensitive marker for identifying pseudonormal mitral inflow in patients with an E/A ratio >1.
