Overview
Acute ventricular septal rupture (VSR) is a life-threatening complication following myocardial infarction, characterized by a tear in the ventricular septum leading to massive left-to-right shunting and hemodynamic instability 12.Diagnosis
Clinical Presentation: Hypotension, shock, and signs of congestive heart failure 12.
Echocardiography: Essential for confirming the presence of VSR and assessing shunt size 12.
Chest Imaging: Chest X-ray may show signs of pulmonary congestion; CT or MRI can further delineate the rupture site 1.
Hemodynamic Monitoring: Continuous monitoring of cardiac output and pressures to guide management 1.Management
Surgical Intervention: Primary treatment, often involving patch closure of the defect 12.
Transesophageal or Transthoracic Echocardiography Guidance: During surgery to precisely locate and repair the rupture 12.
Redo Surgery: Transtricuspid approach can be effective in redo surgeries for post-infarction VSR, particularly for additional valve repairs 2.
Medications: Vasopressors (e.g., norepinephrine) for hemodynamic support; diuretics and inotropic agents as needed 1.Special Populations
Postoperative Complications: Risk of VSR increases post-open heart surgery; careful monitoring of sternal edges and vacuum-assisted closure sites is crucial 1.
Redo Surgeries: Specific techniques like transtricuspid approach may be necessary in patients requiring repeat interventions 2.Key Recommendations
Immediate Surgical Repair: Essential for survival in acute VSR cases (Evidence: Strong 12).
Use of Echocardiography: Critical for diagnosis and guiding surgical intervention (Evidence: Strong 12).
Consider Transtricuspid Approach in Redo Surgeries: Useful for addressing residual defects and associated valve issues (Evidence: Moderate 2).References
