Why the study?

Does an apical systolic murmur reliably indicate incidental mitral regurgitation in patients with dominant mitral stenosis undergoing mitral valvotomy?

Population

Patients with dominant mitral stenosis undergoing mitral valvotomy

Comparison

Clinical assessment of apical systolic murmur vs Surgical findings at mitral valvotomy

Design

Cross-sectional

Implication

Pansystolic apical murmur may flag incidental MR before valvotomy; leaves open need for prospective validation against modern imaging.

Key Points

To determine the diagnostic reliability of an apical systolic murmur in detecting incidental mitral regurgitation during mitral valvotomy in patients with dominant mitral stenosis.
Clinical and surgical records of patients undergoing mitral valvotomy for dominant mitral stenosis were evaluated for the presence of apical systolic murmurs.
Phonocardiography and electrocardiography were utilized to precisely correlate acoustic murmur timing with phases of the cardiac cycle.
Phonocardiographic analysis established that diastolic murmurs definitively signify mitral stenosis caused by inflow obstruction.
Apical systolic murmurs in dominant mitral stenosis serve as secondary diagnostic indicators denoting complicating, incidental mitral regurgitation.
