Background and aims: Early detection of coronary artery disease (CAD) in patients with non-ST elevation acute coronary syndrome (ACS) remains a clinical challenge, especially in the absence of regional wall motion abnormalities by echocardiography on presentation. This study was designed to evaluate the accuracy of Global Longitudinal Strain (GLS)...

Background Ischemic Heart Disease (IHD) is a major and increasing health care issue in Bangladesh. Since the first human percutaneous transluminal coronary angioplasty (PTCA) procedure was performed in 1977, the use of this procedure has increased dramatically, becoming one of the most common medical interventions performed. The technique, original...

Intracardiac thrombi are commonly found in patients with ischemic stroke. The echocardiographic identification of thrombi is important in decision-making since it represents an indication to long-term anticoagulation, in order to reduce the risk of new stroke. Intracardiac thrombi can develop during the time course of several cardiac pathologies th...

Contrast-induced nephropathy (CIN) is a serious complication of angiographic procedures resulting from the administration of contrast media (CM). It is the third most common cause of hospital acquired acute renal injury and represents about 12% of the cases. CIN is defined as an elevation of serum creatinine (Scr) of more than 25% or ≥0.5 mg/dl (44...

Giant left atrium is a rare condition, with a reported incidence of 0.3%, and following mainly rheumatic mitral valve disease. Although rheumatic heart disease represents the main cause of giant left atrium, other etiologies have been reported. Giant left atrium has significant hemodynamic effects and requires specific management. In this review, w...

Hypertrophic cardiomyopathy (HCM) is a genetic disease associated with risk of morbidity and sudden cardiac death. The prevalence, hypertrophy patterns, mode of presentations, and different ECG findings vary in different regions of the world. To date, no data is present regarding these variables in Qatar. A retrospective, cross sectional, descripti...

A study was undertaken on the leaf epidermis of Johannesteijsmannia H.E. Moore in Peninsular Malaysia. In this study, all four species representative of Malaysian Johannesteijsmannia were selected. Result has shown that simple unicellular trichomes are presences sparsely scattered on the abaxial side of the leaf epidermis only in J. magnifica. The...

Lesions most commonly presenting as cardiac mural masses include myxomas, sarcomas, metastatic lesions, and mural thrombus1. Primary tumors of the heart are rare. They have been found in less than 0.02% of unselected patients at autopsy2. Seventy-five percent of these tumors are benign and 50% are myxomas. Prior to the development of cardiac cathet...

We present a case of a 25-year-old male with a large secondum atrial septal defect (ASD) associated with a coronary artery fistula (CAF) between the right coronary artery and the right atrium. The ASD was diagnosed preoperatively by transesophageal echocardio-graphy (TEE). The fistula was found at surgery. The ASD and fistula were closed successful...

To determine the frequency of occurrence of mitral and aortic valvar regurgitation in rheumatic children in whom there was no evidence of carditis acutely or at an earlier attack. Colour flow Doppler imaging was used in a non-randomised study of sequentially admitted children who met the criteria for acute rheumatic fever without clinically evident...

The case of a newborn who had an umbilical catheter inserted in the intensive care unit is discussed. This catheter was meant to be inserted into the umbilical artery, but was instead inadvertently inserted into the umbilical vein. It crossed a patent foramen ovale into the left atrium. This fact was not known at the time of echocardiographic evalu...

Several recent reports1,2 have indicated that Doppler echocardiography, by providing an ultrasensitive modality for studying alterations of blood flow patterns within the heart and great vessels, is capable of unmasking mitral and aortic insufficiency in the absence of murmurs in both the acute and quiescent phases of rheumatic fever. To further in...

Thirteen patients undergoing complete evaluation for double-chambered right ventricle were subjected to phonocardiographic evaluation. Each of these individuals revealed a holosystolic ejection-type murmur which exhibited a similarity of appearance unaltered by the degree of physiologic derangement or associated cardiac abnormalities. This finding...

One hundred twenty-four adult patients consecutively referred for suspected interatrial septal defect (IASD) were studied with contrast echocardiography. In 58 the study eliminated altogether the diagnosis of any significant cardiac defect. Fifteen patients had other forms of cardiac abnormalities with no shunting of blood, and 51 patients had echo...

This report describes a case in which a persistent third aortic arch connection partly palliated interruption of the aortic arch. The malformation occurred without other cardiovascular abnormality in a newborn infant in whom the principal diagnostic clinical finding was the absence of all peripheral pulses except for those of the right brachial and...

In this report we present the current status of dialysis and transplantation in Yemen. The reported incidence of end stage renal disease (ESRD) in one region of Yemen was estimated as 385 per million population (PMP) per year. The total population of Yemen is also estimated as 16,000,000. Peritoneal dialysis was started in 1980, while hemodialysis...
