AIMS The aim of this study is to resolve what event in velocity/time curves represents aortic valve closure (AVC) by comparing the timing of AVC visually seen in high frame rate B-mode images with simultaneously recorded apical tissue Doppler imaging (TDI) and speckle-tracking-based velocity/time curves from normal subjects. METHODS AND RESULTS A total of 73 recordings from 11 normal subjects...

In patients with patent ducts arteriosus, cardiovascular system is generally exposed to much overload and subsequently several complications as congestive heart failure, pulmonary hypertension and infective endocarditis. These complications depend on the size of the defect and the timing of intervention [1]. It is important to close PDA to prevent occurrence of these complications [2]. Today pe...

results the mean age of patients was 60 ± 9.9 years. statistically significant relationship between the occurrence of af with mitral valve annulus, la volume index (lavi) , right ventricle function, and type of surgery (off pump or on pump) were detected in our study (p < 0.05) . there was no statistically significant relationship between the occurrence of af and time interval of p wave to a wa...

Background: Alteration of cardiovascular functions in patients with liver cirrhosis has been described and it correlates with severity of hepatic failure. But cardiac function by conventional echocardiography has limitations and cardiac decompensation occurs when the heart is challenged. Aim: To evaluate cardiac systolic and diastolic functions in patients with liver cirrhosis by conventional D...

OBJECTIVE Mitral valve stenosis (MS) remains as an important cause of morbidity despite evolution in diagnosis and treatment. Generally, left ventricular (LV) systolic functions are well preserved in patients with MS. However, there are some studies showing impaired LV systolic functions in patients with pure MS. The purpose of this study was to evaluate subclinical LV systolic dysfunction in a...

Abstract Background The 2019 novel coronavirus disease (COVID-19) has been reported as pandemy and the number of patients continues to rise. Based on recent data, cardiac injury is a prominent feature disease, leading increased morbidity mortality. In present study we aimed evaluate myocardial dysfunction using transthoracic echocardiography (TTE) tissue Doppler imaging (TDI) in hospitalized CO...

BACKGROUND We sought to validate total atrial conduction time (TACT) measurement via tissue Doppler imaging (TDI) by comparing the electrophysiological study (EPS) measurements of healthy subjects, according to age and sex. METHODS Eighty patients with normal EPS results were included. TACT was measured by EPS and TDI. For validation, the results of TDI were compared with those of EPS. TACT w...

BACKGROUND Tissue Doppler imaging (TDI) is a potentially powerful method for diagnosing myocardial ischemia. This study was designed to investigate how velocity patterns in ischemic myocardium relates to regional function, and to determine whether timing of velocity measurements relative to ejection and isovolumic phases may increase the diagnostic power of TDI. METHODS AND RESULTS In 17 open...
