What is Post-MI Ventricular Septal Rupture?

Post-MI ventricular septal rupture occurs when necrotic septal tissue perforates after acute myocardial infarction. It typically presents in the first week following MI. Its incidence has fallen with widespread reperfusion therapy, but mortality remains very high.

Defects after anterior MI are usually located in the apical septum, whereas those after inferior MI tend to involve the basal posterior septum. The rupture creates an acute left-to-right shunt from the left ventricle to the right ventricle and imposes right heart overload.

Diagnosis is confirmed by urgent echocardiography. Treatment is surgical closure or, in selected cases, percutaneous device closure. Mechanical circulatory support may be used for preoperative stabilization.

Symptoms

New pansystolic murmur after MI
Sudden deterioration and cardiogenic shock
Signs of right-sided heart failure
Jugular venous distension
Hypotension
Pulmonary edema
Low cardiac output findings

Risk Factors

Large transmural MI
Delayed reperfusion
Advanced age
Female sex
Hypertension
Single-vessel disease
First myocardial infarction

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Sudden hemodynamic deterioration after MI
  • Recognition of a new murmur
  • Development of cardiogenic shock
  • Rapid increase in oxygen requirement

Treatment Methods

01
Emergency surgical patch closure of the septal rupture
02
Percutaneous device closure in selected cases
03
Intra-aortic balloon pump
04
Inotropic and vasopressor support
05
Mechanical ventilation
06
Concomitant coronary artery bypass grafting

Kardiyoloji

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Coronary Artery Disease

Kardiyoloji

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Kardiyoloji

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
