Compared to information available on the third and fourth heart sounds in the horse [1] there is a paucity of information on these sounds in cattle in the veterinary literature, although auscultation is the main step in clinical examination of both the cardiovascular system and the animal as a whole. Most literatures describe bovine cardiac sounds and mention that all four heart sounds may be h...

A 3-yr-old intact female snow leopard (Uncia uncia) was evaluated for progressive apathy, lethargy, and decreased appetite. Cardiac auscultation revealed a left basal grade IV/VI systolic ejection murmur, and an echocardiogram confirmed a severe pulmonic valvular stenosis (pressure gradient of 98 mm Hg). The lesion was managed by balloon valvuloplasty, resulting in a marked pressure gradient re...

Post-myocardial infarction ventricular septal defect corresponds to the rupture of the ventricular septum between the healthy and infarcted parts. It is a rare complication still associated with a high mortality rate. Its diagnostic should be evoked in case of pathologic cardiac auscultation and confirmed by emergent transthoracic echocardiography. Hemodynamic stabilisation, mainly with the ins...

We describe a cardiac arrest during use of an argon beam coagulation (ABC) system in an 82-yr-old woman having laparoscopic cholecystectomy under general and epidural anaesthesia. Intra-abdominal pressure (IAP) was controlled to less than 12 mm Hg during a carbon dioxide gas pneumoperitoneum and at first the operation was uneventful. When the ABC system (gas flow 6 litre min(-1)) was used to co...

Fetal heart failure and hydrops fetalis may occur due to systemic arteriovenous fistula because of increased cardiac output. Arteriovenous fistula of the central nervous system, liver, bone or vascular tumors such as sacrococcygeal teratoma were previously reported to be causes of intrauterine heart failure. However, coronary arteriovenous fistula was not reported as a cause of fetal heart fail...

A 53-year-old man was admitted to our center with dyspnea and peripheral edema compatible with cardiac failure. His history was notable for Noonan syndrome, but he had not been seen a physician for 15 years. On examination, pectus excavatum, pectus carinatum, and low implantation of the ears were present (Figure 1). Blood pressure was 145/ 70 mm Hg, and pulse was irregular at 90 to 100 beats pe...

Electrocardiographic (ECG) artefacts may closely simulate both supraventricular and ventricular tachycardias. We describe a case initially diagnosed as rapid atrial fibrillation, based on 12-lead surface ECG (especially the limb leads) and monitor tracing. The arrhythmia was resistant to beta blockers. Because of the at times apparently regular rhythm, an esophageal ECG recording was performed,...

Coxiella burnetii myocarditis is a rare but severe clinical form of acute Q fever. We report the case of a 40-year-old man hospitalized for acute febrile syndrome. Forty-eight hours later, he presented dyspnea, orthopnea, and paroxysmal nocturnal dyspnea; cardiac auscultation revealed a third sound and echocardiography showed a diffusely hypokinetic and dilated left ventricle (30% ejection frac...

Heart auscultation (the interpretation by a physician of heart sounds) is a fundamental component of cardiac diagnosis. It is, however, a difficult skill to acquire. In this work, we develop a simple model for the production of heart sounds, and demonstrate its utility in identifying features useful in diagnosis. We then present a prototype system intended to aid in heart sound analysis. Based ...
