We compared the cardiac output measured by the transpulmonary aortic single indicator thermodilution method with that by the pulmonary artery catheterization in a patient with ventricular septal rupture after acute myocardial infarction. Though the former cardiac output was lower than the latter, in the presence of the ventricular septal rupture, the cardiac outputs were equal after the rupture...

Spontaneous rupture of the oesophagus is an uncommon surgical emergency. A case is presented in which the extensive nature of the rupture precluded standard methods of treatment and was treated by transhiatal oesophagectomy.

The source processes of the 4 January 1970, Tonghai earthquake (Ms = 7.5) and the 6 February 1973, Luhuo earthquake (Ms = 7.5) in southwestern China were investigated using an inversion technique on the very complex body waves. The two earthquakes were associated with 48 and 90 km of surficial strike-slip rupture, respectively, and the distribution of displacement with distance along the fault ...

High-frequency seismic waves are generated by abrupt changes of rupture velocity and slip-rate during an earthquake. Therefore, analysis of high-frequency waves is crucial to understanding the dynamic rupture process. Here, we developed a hybrid back-projection method that considers variations in focal mechanisms by introducing a non-planar fault model that reflects the subducting slab geometry...

A 78-year-old asymptomatic male with a history of coronary artery disease was admitted for preoperative cardiovascular evaluation before noncardiac surgery. Auscultation revealed a Grade 3 holosystolic murmur at the left parasternal area. Transthoracic echocardiography documented ventricular double rupture (VDR), consisting of ventricular septal rupture, and rupture of the apical part of the le...

Vascular Ehlers-Danlos Syndrome (vEDS) is a dominantly inherited connective tissue disorder characterised by colon rupture and arterial aneurysm, dissection and rupture. A patient was diagnosed with vEDS after a spontaneous colon rupture when he was brought to our institute because of sudden chest pain. An ECG revealed wide regional ST elevation, which was initially suggestive of acute myocardi...

Rupture of the heart occurs almost always as a result of myocardial infarction and then usually in the left ventricle. Less frequently, ruptures are caused by bacterial infection, formation of abscesses, and aneurysms (Hudson, 1965). The diagnosis of rupture of the heart in this case was made before necropsy, thereby warning the dissector to avoid injury which has been suggested to be the cause...

Ischemic rupture of the anterolateral papillary muscle is uncommon due to its dual blood supply. It usually follows an ischemic event involving branches of the left circumflex or left anterior descending arteries. We present a case of a patient admitted with an acute inferior wall myocardial infarction and an isolated distal right coronary artery occlusion. Acute mitral regurgitation with ruptu...

Postemetic rupture of the esophagus, also known as spontaneous rupture or Boerhaave's syndrome, was first described by Herman Boerhaave in 1724. This is a severe disease that causes high mortality rates and is difficult to diagnose not only because it is rare but also because it is frequently confused with other severe clinical conditions, such as acute myocardial infarction, perforated peptic ...

Coronary artery atherosclerosis is the major cause of mortality and morbidity in the industrialised world. Progressive narrowing of coronary arteries causes angina. However, it is rupture of the plaque that causes the catastrophic consequences of atherosclerosis, such as myocardial infarction. Recent work has identified that the stability of the plaque rather than its absolute size determines t...
