Incessant atrial premature beats as a potential cause for tachycardia-induced cardiomyopathy was suspected in a patient presenting with dilated non-ischemic cardiomyopathy and severely altered left ventricular ejection fraction. The elimination of a left atrial focus by percutaneous RF ablation led to normalization of the clinical status, of atrial and ventricular dimensions and left ventricula...
OBJECTIVE To assess independent determinants of beat to beat variation in left ventricular performance during atrial fibrillation. DESIGN Prospective study. SETTING University hospital. PATIENTS Seven patients with chronic non-valvar atrial fibrillation. INTERVENTIONS Invasive and non-invasive haemodynamic variables were assessed using a non-imaging computerised nuclear probe, a balloon...
Background: Chronic obstructive pulmonary disease (COPD) and heart failure are prevalent comorbidities affecting a vast proportion of the world population, responsible for significant morbidity and mortality, their coexistence is more frequent than previously recognized that poses important diagnostic and therapeutic challenges. We intend to determine the prevalence of concomitant left ventricu...
Left atrial plication (LAP) following Kawazoe's method was performed on eight patients with mitral valve stenosis associated with a giant left atrium. To investigate the effect of LAP particularly on left ventricular function, the preoperative and postoperative left ventricular function in these patients were compared. The data were also compared to that of the non-left atrial plication (non-LA...
BACKGROUND Left ventricular hypertrophy is influenced by both hemodynamic and non-hemodynamic factors. Ambulatory blood pressure is correlated with left ventricular hypertrophy. We established the influences of hemodynamic and non-hemodynamic factors, including ambulatory blood pressure, on variation in left ventricular mass in healthy Korean adults. METHOD We included 172 subjects (male = 71...
BACKGROUND Left ventricular hypertrophy is a forerunner of coronary heart disease, congestive cardiac failure, stroke and may also lead to sudden death. Estimation of left ventricular mass by echocardiography offers prognostic information better than the evaluation of traditional cardiovascular risk factors. OBJECTIVE The aim of this study was to determine the relative contributions of haemod...
background many types of cardiovascular complications such as; cardiac arrhythmias, impaired cardiac function, myocardial ischemia and decreased left ventricular function, have been attributed to interferon therapy. objectives the aim of this study was to evaluate the effects of combination therapy pegylated interferon and ribavirin on left ventricular systolic and diastolic functions in patien...
The Turkmen horse is one of the oldest and purest breeds in the world. There is no information with regards to the normal echocardiographic parameters of this horse regarding to cardiac diseases. Pulsed-wave (PW) Doppler echocardiography was performed on 42 clinically normal 3- to 15-year-old racing Turkmen horses. There were 26 stallions and 16 mares. The left ventricular isovolumetric contrac...
