A UNIQUE AND RARE PRESENTATION OF ADULT CONGENITAL HEART DISEASE: COMMON ATRIUM ASSOCIATED WITH CORONARY ANEURYSMS AND FISTULA

A Unique and Rare Presentation of Adult Congenital Heart Disease: Common Atrium Associated with Coronary Aneurysms and Fistula

An atrial septal defect is the second most common congenital heart disease found in adults with a female to male ratio of 4 : 1.However, it is rare to have a complete absence of the interatrial septum (IAS) to be diagnosed in an elderly patient associated with other coexisting anomalies.We present a case of a 60-year-old female presenting with comm

On Deadlock Analysis and Characterization of Labeled Petri Nets with Undistinguishable and Unobservable Transitions

This work addresses the analysis and characterization of deadlocks in discrete-event systems modeled by labeled Petri nets (LPNs) with undistinguishable and unobservable transitions.To provide a solution for the notorious problem, it is essential to present an effective characterization in such a way that deadlock control and synthesis are technica
