There's also the two Jake Hunter games.
Another Code, aka Trace Memory, is sometimes regarded as a fusion of adventure game and visual novel.
Likewise, the Life Signs game has been called a combination of surgery game and visual novel.
Lux-Pain was released in English, but I haven't heard many good things about it. It has an overall score of 48 on Metacritic (assuming you trust the site and reviewers...)
Tecmo Koei released a serious visual novel in English called Again. It has an overall score of 52 on Metacritic.
The early DS game Sprung is a western romance game. I don't know if it's well regarded. It shows up in bargain bins quite a bit...
Finally, regarding fan translations... Jjjewel finished work on Tokimeki Memorial Girl's Side DS back in December 2010. And it looks like a complete translation for the second Girl's Side game will be released in the next few days. Please keep in mind that translation patches will not work with a legit import cartridge.
