My daughter who is 16 has been diagonosed as having a redundant mitral valve. (through a heart scan) My gp says it is nothing to worry about. I have read it is the same as mitral valve prolapse. Is this correct? My daughter was initially experiencing chest pain palpatations, heart pounding , shortness of breath, fatigue, heart racing. She now experiences chest pian whilst excercising at the gym. Is there anything I should be doing. Will her condition get worse?
