Valvular lesions- MR

MR causes
leaflet( MVP/ endocarditis/ rheumatic fever), MI

clinical examination
- displaced forceful apex beat
-AF
-soft S1, PSM radiating to axilla , loud S3


TEE good coz MV closest to esophagus

CXR: dilated LA , +/-
ECG:AF, LA dilatation


SV usually preserved until late
surgery if functional status <4 METS
if mixed lesion- deal with dominant lesion first.

Goals: high normal HR (slower--> more time for diastolic filling and larger volume regurg), adequate preload, low afterload, low PVR
