Ventricular septal rupture (VSR) is a rare condition that carries significant morbidity and mortality. It occurs as a complication of myocardial infarction affecting the interventricular septum. The introduction of thrombolytic therapy has reduced its incidence.
Ventricular septal rupture (VSR) commonly occurs as a result of myocardial infarction (MI). VSR is a rare condition that occurs in 0.3% of individuals who have suffered MI, and it carries high morbidity and mortality . Although the introduction of thrombolytic therapy has resulted in the reduction of VSR incidence, cases still occur  . Risk factors include advanced age, female sex, chronic renal diseases, and cardiovascular diseases  .
Typically VSR may present as worsening of a patient's condition after recent MI, following a short period of clinical stability and usually with complaints of chest pain and dyspnea . Mitral valve regurgitation (MVR) may present in a similar way as VSR and is thus one of the main differential diagnoses, notwithstanding that MVR complicates one in five cases of VSR. Upon examination, a significant percentage of patients have a loud holosystolic murmur, most prominent in the left sternal border, which may radiate to several areas in the chest. In addition, there is commonly a parasternal thrill. Murmurs produced by both VSR and MVR may radiate to the axilla, however, an MVR murmur is usually loudest at the apex and can be heard during diastole.
Further complications of VSR that may ensue are low cardiac output, which in turn leads to cardiogenic shock. In such cases, the characteristic murmur is less intense, and a thrill may be completely absent. There is a prominent second heart sound, pulmonary hypertension, and possibly tricuspid regurgitation as well.
An atypical presentation has been described with features of VSR emerging as the first manifestation of the disease, after a silent MI .

Medical history and medical imaging are major parts of the diagnostic process. Imaging modalities include:
- ECG: Which may show signs of myocardial infarction, as well as its location .
- Chest radiograph: Cardiomegaly and features of congestive heart failure may be present, and are easily seen on a plain film.
- Right heart catheterization: This is a dated method that is no longer commonly used in diagnosis.
- Doppler echocardiography (DE): DE can also be used as a diagnostic modality  . It provides information on the location and extent of rupture, as well as about cardiac function, with a high sensitivity and specificity. The transesophageal method may prove more accurate in severely ill patients.
- Radionuclide scintigraphy: This test is able to measure the amount of blood shunted through the septal defect, as well as ventricular function.
- Left ventriculography: This can also be used to diagnose septal rupture.
- Coronary angiography: This imaging technique is useful in planning a future intervention, particularly revascularization.
We analyzed the short-term prognosis factors of VSR and established the short-term prognosis index of VSR (SPIV) based on the Logistic regression analysis to stratify patients with VSR. [ncbi.nlm.nih.gov]

For the infarct lesion, this approach provides excellent results with sufficient closure of the VSR and prevention of the ventricular remodeling for five years. [ncbi.nlm.nih.gov]
In addition, increased stiffness of the patch around the septal defect prevented deformity of the patch and reduced stress on the suture line. [link.springer.com]
Reduction of afterload is required to prevent tension in the suture line of newly repaired septum during the post-bypass period. To achieve these goals, nitroglycerin infusion was started. [saudija.org]
