Hi, I'm from the Philippines. My brother has a heart problem. His doctors found out that he has severe aortic insufficiency secondary to aortic-annular ectasia, chronic renal insufficiency secondary to hypertensive nephrosclerosis, hypertension, controlled.. Could you explain further in layman's term? He's still currently under observation. His doctors are somewhat not sure about how will they operate him because they said that this is a very rare heart problem.
