Background Undersized ring annuloplasty is a commonly used surgical repair for ischemic mitral regurgitation, in which annular downsizing corrects but alters valve geometry and elevates tissue stresses. In this study, we investigated if unphysiological leaflet kinematics after might cause pathogenic biological remodeling of the leaflets, preserving physiologic with better technique can moderate such adverse remodeling. Methods Results Twenty‐nine swine were induced survivors assigned to...
The COVID-19 pandemic highlighted significant gaps in equitable access to essential medical countermeasures such as vaccines. Manufacturing capacity for vaccines, therapeutics, and diagnostics is concentrated too few countries. One of the major hurdles vaccine distribution was "vaccine nationalism", countries hoarded vaccines vaccinate their own populations first which significantly reduced global supply, leaving parts world vulnerable virus. As part equitably building capacity, one proposal...
Undersizing mitral annuloplasty (UMA) to repair functional regurgitation lacks durability, as it forces leaflet coaptation without relieving the sub-leaflet tethering forces. In this biomechanical study, we demonstrate that papillary muscle approximation (PMA) prior UMA can drastically relieve and improve valve function, need for significant annular downsizing.An ex vivo model of (FMR) was used, in which pig valves were geometrically perturbed induce FMR, repairs performed. Nine studied...
This article focuses on the stone inscriptions ascribed to Ashoka, 3rd century BC ruler of Mauryan dynasty in ancient India. The locations 29 known and 8 environmental predictors at 1 km pixel resolution were entered into a species distribution model, that reliably predicted Ashokan edicts (AUC score 0.934). Geologic substrate (33%), population density AD 200 (21%), slope (13%) explained majority variance edict locations. We have identified 121 possible Indian subcontinent conform same...
ObjectiveRedo aortic surgery has a higher risk of morbidity and mortality because it is technically complex due to mediastinal adhesions, infection, previously implanted prostheses. In this study, we sought benchmark our single-center experience comparing outcomes in patients undergoing after 1 versus multiple previous cardiac operations.MethodsBetween 2004 2019, 429 underwent redo surgery. They were classified as (first surgery, n = 360) 2 or more (multiple) surgeries (multiple 69)....
Omental lipomas are extremely rare tumors of childhood. We report a case solitary giant lipoma the omentum in child, successfully managed by complete excision, without any recurrence on follow-up study.
Abstract
Introduction: Intra-ventricular papillary muscle banding (PMB), is a new mitral repair technique for ischemic regurgitation (IMR), which reduces lateral distance between the two muscles to relieve leaflet tethering (Fig A). In this study, we compared hemodynamic efficacy of PMB against undersized annuloplasty (UMA) and combination UMA, in chronic swine IMR model. Methods: Six were induced with via percutaneous infarction postero-lateral wall left ventricle(LV), followed 6 weeks develop...
