Pulmonary vein and right side of the heart?

I left a note in the article where it says "the now adult worms migrate to the heart through the pulmulnary vein to the right side of the heart..." because the pulmonary vein (at least in humans) leads to the left atrium of the heart. So is this an error? Which side do they really travel to, and which blood vessel do they really use? Many thanks, delldot | talk 02:11, 9 January 2006 (UTC)

I went ahead and corrected that. You were right. -- Joelmills 02:02, 16 January 2006 (UTC)

"Once the infestation reaches a certain concentration in the lungs, the now adult worms migrate from the pulmonary artery to the right side of the heart and begin to reproduce in ernest, filling the blood with microfilariae. " This sounds a bit strange to me. Do they migrate from the pulmonary artery to the right side of the heart against the flow of blood? I never heard of anything going 'upstream' in the blood. Or do you mean they go pulmonary artery ->lung->pulm. vein -> left side of heart -> body -> right side of the heart? Assuming the vascular system in dogs is similar to the human one.

Initially the larvae reach the circulatory system and migrate to the small pulmonary arteries. There they grow into adults and then migrate back (upstream) to the right ventricle. They never enter the pulmonary vein or left side of the heart. The offspring, microfilaria, do go through the whole circulatory system. --Joelmills 17:46, 16 January 2006 (UTC)

Heartworm in other animals?

I came here to research heartworm disease in cats, which to my knowledge differs significantly from dogs. Nearly all of the information here pertains to dogs, even though cats are also susceptible. I don't know enough about this to edit the article myself (hence coming here to learn more), but I strongly urge someone who DOES know about feline heartworm disease to share their knowledge. I really hope someone will take this into consideration. As I have found out, no matter how much less prevalent feline heartworm is, it can be just as devastating for the millions of cat owners worldwide.

Give me a few days and I will add that information. --Joelmills 03:33, 26 July 2007 (UTC)

Diagnosis section - unclear wording

The "Diagnosis" section currently contains the sentence "However, the potential for a microfilaremic infections is 5-67%." I assume this means "Between 5% and 67% of dogs infected with A. reconditum are also infected with D. immitis", but I don't know enough about the subject to change the wording myself. Could someone who does know make the appropriate change? Thanks. Tevildo (talk) 00:28, 26 December 2018 (UTC)
