BACKGROUND AND AIM OF THE STUDY Appropriate experimental models are needed to study the mechanisms underlying left ventricular (LV) remodeling and functional ischemic mitral regurgitation (IMR). Herein is described an original percutaneous method for inducing a well-defined posterolateral infarct and significant IMR. METHODS Under videofluoroscopic guidance, the second (OM2) and third (OM3) o...
background it has been shown that trend of achieving to millennium development goal 4 (mdg 4), varies by region and between countries, indicating the possibility of existing different barriers and/or facilitators. objectives this study aimed to evaluate the trend of under five mortality rate (u5mr), and infant mortality rate (imr) and explore the main challenges to reach mdg 4 by 2015. patients...
BACKGROUND Previous experimental studies demonstrated that central septal-lateral (SL) annular cinching (SLAC) abolishes acute ischemic mitral regurgitation (IMR), but whether localized cinching near the anterior (ACOM) or posterior (PCOM) commissure is equally effective is unknown. METHODS Six adult sheep underwent implantation of 9 radiopaque markers on the left ventricle, 8 around the mitr...
BACKGROUND In chronic ischemic heart disease, focal stenosis, diffuse atherosclerotic narrowings, and microcirculatory dysfunction (MCD) contribute to limit myocardial flow. The prevalence of these ischemic heart disease levels in fractional flow reserve (FFR) interrogated vessels remains largely unknown. METHODS AND RESULTS Using intracoronary measurements, 91 coronaries (78 patients) with i...
OBJECTIVE To summarize the experience in surgical technique and clinical results of treating ischemic mitral regurgitation (IMR). METHODS From April 1998 to September 2004 fifty-three IMR patients, 8 with mild-moderate IMR, 24 with moderate IMR, and 21 with severe IMR, underwent coronary artery bypass grafting (CABG) combined with mitral valvuloplasty (MVP, n = 33) or mitral valve replacement...
BACKGROUND Edge-to-edge approximation of the mitral valve leaflets (Alfieri procedure) is a novel surgical treatment for patients with ischemic mitral regurgitation (IMR). Long-term durability may be limited if abnormal mitral leaflet stresses result from this procedure. The aim of the current study was to measure Alfieri stitch tension (F(A)) and to explore its geometric determinants in an ovi...
Introduction This study was conducted to examine whether bleomycin-induced growth inhibitory action on human neuroblastoma cells (IMR-32) is influenced by anti-inflammatory metabolites of polyunsaturated fatty acids (PUFAs): lipoxin A4 (LXA4), resolvin D1 and protectin D1 in vitro. Material and methods The in vitro study was conducted using monolayer cultures of exponentially growing IMR-32 c...
BACKGROUND India is in a race against time to achieve the Millennium Development Goals (MDGs) 4 and 5, to reduce Infant Mortality Rate (IMR) to '28' and Maternal Mortality Ratio (MMR) to '109', by 2015. This study estimates the percent net contribution of the states and the periods in shaping India's IMR/MMR, and predicts future levels. METHODS A standardized decomposition technique was used ...
BACKGROUND Ischaemic mitral regurgitation (IMR) is a detrimental complication of ST elevation myocardial infarction (STEMI). OBJECTIVE We sought to determine patient characteristics and outcomes of patients with IMR with focus on anterior or inferior location of STEMI. METHODS All patients presenting with STEMI complicated by IMR to our centre who underwent primary percutaneous coronary int...
Neonatal (NMR), infant (IMR) and under-five (U5M) mortality rates remain high in Nigeria. Evidence-based knowledge of trends and drivers of child mortality will aid proper interventions needed to combat the menace. Therefore, this study assessed the trends and drivers of NMR, IMR, and U5M over a decade in Nigeria. A nationally representative data from three consecutive Nigeria Demographic and H...
