作者： Sohail Siddique Najdat Bazarbashi Abdullah Ashmeg Asif Mahmood Abdul Aziz Alhosan Amro Saeed Department of cardiac Surgery Prince Sultan Cardiac Center Prince Sultan Military Medical City Riyadh KSA

Myriad surgical and medical remedies including Extracorporeal Membrane Oxygenation (ECMO) are being employed for acute right ventricle with varying results. Very few cases have been documented in literature regarding the role of VA ECMO for right ventricular failure after open heart surgery. We retrospectively analyzed all cases eliciting VA ECMO for post-operative right heart failure over a period of 24 months. Data was completely delineated for demography, pre-operative patient status at length, brief venipuncture course, indications for VA ECMO and its outcome after institution.

A Rare Case of Successive Pregnancies in a Woman with Complex Cyanotic Congenital Heart Disease after Glenn Palliation

World Journal of Cardiovascular Diseases 2017年第12期7卷 423-428页

作者： Marwa Mohamed Shazia Mohsin Merna Atiyah Ahmed Al Zahrani Khalid Alnajashi prince sultan cardiac center Riyadh KSA

The bidirectional Glenn procedure is an integral step in the optimal palliation for single ventricular physiology in many forms of complex congenital heart disease. An increasing number of women who have undergone this connection in childhood are now reaching childbearing years. Low pulmonary blood flow and volume over load on the single ventricle pose several problems during pregnancy. We are reporting a 33-year-old lady with congenital tricuspid atresia and mild pulmonary stenosis who had late Bidirectional Glenn procedure with pulmonary forward flow and later underwent six successful pregnancies, with delivery of six low birth weight babies with no reported complications.

World Journal of Clinical Cases 2017年第4期5卷 140-147页

作者： Ebtissam Saleh Almeghaiseeb Muhammad Farooq Ashraf Reem Abdullah Alamro Abdulaziz Omar Almasoud Abdulrahman Ali Alrobayan prince sultan Military Medical City

AIM To evaluate the safety and efficacy of intragastric balloon(IGB) in weight reduction in obese patients referred to a tertiary hospital in the Kingdom of Saudi *** Three hundred and one consecutive obese individuals, who underwent IGB placement during January 2009 to May 2015, were analyzed. The subjects aged 18 to 60 years and had a minimum body mass index(BMI) of 27 kg/m^2. The IGB was placed under conscious sedation and kept for 6 mo. Anthropometric measurements were recorded during and after 6 mo of IGB *** The body weight, excess body weight, and BMI were significantly reduced at the time of IGB removal and 6 mo later. Body weight loss > 10% was achieved in 224 subjects at removal of IGB. End of treatment success and long-term success were both significantly observed in women(70 vs 11)(71 vs 12.5) respectively. Excess BMI loss was significantly higher in subjects retaining the IGB for over 6 mo both at the removal [43.44 ± 19.46(n = 221) vs 55.60 ± 28.69(n = 80); t = 4.19, P = 0.0001] as well as at the end of 6 mo' follow-up [46.57 ± 24.89(n = 221) vs 63.52 ± 31.08(n = 80); t = 4.87, P = 0.0001]. Within 3 d of IGB placement, two subjects developed pancreatitis and one subject developed cardiac arrhythmia. Intestinal obstruction due to displacement of IGB occurred in two subjects. Allthese subjects recovered uneventfully after immediate removal of the IGB. CONCLUSION IGB was effective in our cohorts. The observed weight reduction was maintained for at least 6 mo post IGB removal. IGB placement was safe with a satisfactory tolerance rate.
