Most common valvular heart diseaseCommonest causes are:
Degenerative Calcific
Rheumatic Bicuspid Congenital
Rarer:
Paget’s , Fabry’s, irradiation,

Exertional anginaExertional dyspnoeaExertional dizziness/lightheadedness
Leading to
Chest pain, heart failure and syncope

O/E:Pulsus parvus et tardusNarrowed pulse pressureHeaving apex Auscultation:ESM aortic area radiating to carotidsCan be heard in the apex (Gallavardin phenomenon)Soft S2Paradoxical splitting (P2 precedes, comes closer to A2 in inspiration)S4The more severe, the longer and later peaking the murmur.Accentuated with squatting

Treatment and progress
Started on beta-blockersPlanned for elective AVR – decided on bioprosthetic valve.Had coronary angiography done, which showed mid LAD disease 70%.Hence had AVR with CABG – LIMA to LAD. Asymptomatic and well since then.
