The chapter examines four different types of pattern- based features: local binary pattern (LBP), local ternary pattern (LTP), difference of Gaussian LTP (DoGLTP), and ternary co-occurrence pattern (LTCoP).

The performance of the methods shows that the combination ofoneor moremethods ofimage fusion is effective incardiac image analysis.

Mitral regurgitation (MR) is a mitral valve insufficiency that causes a change in the size and/or shapeoftheLV,affectingitsfunctioningandresultingfromischemicheartdisease[2,3].MRleads tomyocardialinfarction(MI)inabout20%ofcases[4,5].TheseverityofMRincreasesaround30%in patients suffering from coronary artery disease (CAD) with ischemic LV dysfunction [6]. TherearemanyapproachesavailabletodiagnoseMRthatarehelpfulindeterminingseveritygrade anddysfunction[7–13].Diagnosticmethodsincludeassessmentofregurgitationvolume,orificesize, orifice,andregurgitantorificewiththehelpofechocardiographyorcatheterization.Inaddition,two- dimensional (2D) contrast echocardiography and Doppler echocardiography are efficient ways for assessingMR.We discuss the advantages ofthese techniques later in the chapter [14–20]. To begin, this chapter discusses different heart conditions by categorizing heart valves and their relateddiseases,withaspecialfocusonMR.Italsopresentsvariousdiagnosticmethodsandthequal- itativeandquantitativeparametersusefulingradingMRseverity.Finally,thechapterendswithadis- cussion ofdifferent modes and techniques ofechocardiography. 1.2 Heart valves Thetwoatrioventricular(AV),one-wayvalvesarethinstructures,havingconnectivetissuesanden- docardia.Thesevalves,namely,thebicuspid/mitralandthetricuspidAVvalvesarelocatedbetween theLAandtheLV,andtheRAandRV,respectively.Thetwosemilunar,one-wayvalvesaremadeup ofthreeflaps,eachcomposedofconnectivetissuesandendocardiumaswellasfiberstopreventthe valvesfromflappinginsideout.Theirshapesarelikeahalfmoonandthustheyarecalledthesemilunar
