are side effects/symptoms be different when chemo delivered into the heart artery through a port tha

can chemo delivered straight into the heart artery be different in side effects than the arm veins? has anyone experienced any complications because chemo was delivered through the port rather than the arm veins? i'm talking about the difference between an arm vein and the heart vein. does anyone know if there's any difference at all in side effects because one goes straight into your heart? can chemo delivered through the heart vein cause heart problems compared with the arm vein?

since i got my port i've had symptoms from ac chemo no one can explain. and i dont know if its the chemo or the port or what... my chest feel pressured then that night my neck and face feels swollen or constricted or circulation cut off, that kind of feeling, then i'm stuck with a feeling of throat constriction (like i'm being strangled) for 2 weeks... feeling like i have a pair of invisible hands choking me at my throat is ... i can't even explain how i am still living... its the first time in my life i have thought that i'd be better dead. i've also had really horrible heartburn indigestion... its been hard to eat, hard to sleep and harder to keep my mind on anything else this past month... i had my last ac chemo last week, so next will be taxol... i am hoping that its not the port that is causing this but not one doctor can explain what is happening to me and one even said to me that its "all in your mind".

sending love to everyone...
