Continuous murmur caused by a ventricular septal defect post-myocardial infarction: visual display with a handheld...

Area of Science:

• Cardiology
• Cardiac Surgery
• Internal Medicine

Background:

• Ventricular septal defects (VSDs) are typically associated with specific murmur characteristics.
• Continuous murmurs are rarely linked to VSDs, with prior reports exclusively involving congenital defects.

Observation:

• A patient presented with an acquired ventricular septal defect following a significant anterior myocardial infarction.
• A continuous murmur was detected in this patient, which is an atypical presentation for VSD.

Findings:

• The continuous murmur associated with the acquired VSD was objectively confirmed using 2D echocardiography.
• Advanced diagnostic tools, including a specialized stethoscope coupled with a computer for visual display, corroborated the continuous nature of the murmur.

Implications:

• This case expands the understanding of potential VSD presentations, particularly in the context of ischemic heart disease.
• The findings suggest that acquired VSDs, especially post-myocardial infarction, should be considered in the differential diagnosis of continuous murmurs.
• Further investigation into the mechanisms underlying continuous murmurs in acquired VSDs is warranted.
