OBJECTIVE To study the development of noncompaction of the ventricular myocardium (NCCM) in the state of Qatar and to highlight the prognostic parameters in those patients. METHODS We conducted this study from 2000 to 2004 on patients who were referred to Hamad General Hospital with questionable echocardiographic features of cardiomyopathy with or without(More)
Our studies have established that a single intracardiac administration of the retroviral vector containing angiotensin II type I receptor antisense gene causes prolonged antihypertensive actions in the spontaneously hypertensive rat. These results suggest that antisense gene therapy is a conceptually valid strategy for the control of hypertension at the(More)
OBJECTIVE Over one billion Muslims fast worldwide during the month of Ramadan. Fasting during Ramadan is essentially a radical change in lifestyle for the period of one lunar month, so it is important to see the response of congestive heart failure patients to this change. Our objective in this study is to investigate whether Ramadan fasting has any effect(More)
OBJECTIVE Biogenic amine brain levels and their cerebral metabolism are frequently studied by quantitation of biogenic amine metabolites in cerebrospinal fluid (CSF) compared to age-matched controls. There is a paucity of studies in adolescents and young adults investigating the potential role of disordered cerebral biogenic amine metabolism in young(More)
Different devices have been used for percutaneous closure of ventricular septal defects (VSDs). Over the past 6 months, we have used the Amplatzer duct occluder for VSDs associated with tunnel-shaped aneurysm in three patients here at our institution. Due to the anatomic resemblance between such VSDs and the duct occluder, we selected this device for(More)
Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical condition and not readily recognized early and managed accordingly. Acute rheumatic fever, which is a common disease in developing countries, does not commonly present with UPE. We report a 13-year-old girl presenting with UPE following acute rheumatic fever mimicking pneumonia. We conclude(More)
S ustained fasting over a period is a feature of several of the world’s great religions. One of the five fundamental rituals of Islam is fasting during the month of Ramadan. Muslims neither eat nor drink anything from dawn until sunset. Fasting may have negative effects on cardiac patients because of the limited time allowed for food intake and the heavy(More)
Fenestrated atrial septal defects (F-ASDs) may pose a challenge to device closure; recently, a cribriform device with a minimal connecting intrawaist diameter and large, equal left- and right-sided discs has been designed to cover more than one adjacent defect. This study demonstrates the feasibility and technical aspects of closing F-ASDs using this new(More)
OBJECTIVES To report the rates of cardiomyopathies in the population below 50 years of age in Qatar. SUBJECTS AND METHODS We conducted a retrospective review of clinical data on patients with cardiomyopathy who were hospitalized in Hamad General Hospital, Doha. Data were collected from medical records during the 1996-2002 period and prospectively from the(More)
