BACKGROUND Right heart dysfunction confers significant morbidity and mortality after left ventricular assist device implantation and historically occurs in as many as a third of patients. It is unknown whether newer axial flow pumps have a different impact on postimplant right heart dysfunction. We compared the incidence of right heart dysfunction after implantation of the pulsatile HeartMate I...

Glossopharyngeal insufflation (GI), a technique used by breath-hold divers to increase lung volume and augment diving depth and duration, is associated with untoward hemodynamic consequences. To study the cardiac effects of GI, we performed transthoracic echocardiography, using the subcostal window, in five elite breath-hold divers at rest and during GI. During GI, heart rate increased in all d...

stress-induced cardiomyopathy or takotsubo cardiomyopathy is a recently increasing diagnosed disease manifested by transient apical or mid left ventricular dilation and dysfunction. this sign is similar to acute myocardial infarction but without significant coronary artery stenosis. there are important and essential differences between takotsubo cardiomyopathy and acute myocardial infarction in...

introduction: chest x–ray is one of the most common method of imaging. cardio thoracic ratio ( ctr ) is one of the parameters of chest x–ray that is used for determining cardiac enlargement. echocardiography as compared to chest x–ray is expensive and all centers dont have it, but it can determine heart size, valvular diseases, ejection fraction, left ventricular hypertrophy (lvh), pericardial ...

BACKGROUND Echocardiographically assessed right ventricular dysfunction is increasingly used to guide more aggressive therapy in hemodynamically stable patients with acute pulmonary embolism (PE). However, the prognostic value of right ventricular dysfunction in these patients is still unclear. METHODS We systemically reviewed the literature to assess the prevalence of echocardiographic right...

A patient with end stage heart failure underwent permanent implantation of a Novacor left ventricular assist system. Progressive right ventricular dysfunction developed during the first two postoperative weeks. Temporary and subsequently permanent atrioventricular pacing to correct first degree heart block improved the performance of the device, with sustained resolution of his right ventricula...
