Post-Myocardial Infarction Ventricular Septal Defect Six Months following Coronary Artery Bypass Grafting

Area of Science:

• Cardiology
• Cardiac Surgery
• Mechanical Circulatory Support

Background:

• Mechanical complications post-myocardial infarction (MI) carry significant mortality risks.
• Ventricular septal defects (VSDs) are a known, albeit infrequent, mechanical complication of MI.
• Coronary artery bypass grafting (CABG) is a common intervention for ischemic heart disease.

Observation:

• A novel case of VSD occurring within six months of CABG is presented.
• The patient developed a VSD following acute myocardial infarction, despite recent revascularization surgery.
• This specific timing presents a unique clinical challenge.

Findings:

• Successful surgical correction of the VSD was achieved.
• Mechanical circulatory support (MCS) was instrumental in managing the patient's cardiogenic shock during the intervention.
• The VSD was a de novo complication post-MI and post-CABG.

Implications:

• This case underscores the critical role of MCS in managing complex cardiogenic shock.
• It highlights the possibility of rare mechanical complications like VSDs even after successful revascularization.
• Early recognition and intervention with MCS can be life-saving in such challenging scenarios.
