Aortic regurgitation is a
volume overloaded situation. Patients experience the following symptoms.
1. Palpitation
2. Exertional
dyspnea
3. Angina
What
is the mechanism fo angina in Aortic regurgitation ?
It is due to the imbalance between myocardial oxygen demand
and oxygen supply. There is increased demand due to the left ventricular
hypertrophy. Decreased supply is due to decreased coronary artery perfusion
gradient. Decreased coronary artery perfusion
gradient is due to increased left ventriocular end diastolic pressure (LVEDP) and decreased aortic diastolic blood
pressure.
