A downright HUGE chunk of episodic TV could be defined as "soap operas". Anything with an ongoing dramatic storyline could qualify... So yes, House MD could very well be considered to have "soap opera" aspects, altho it's hardly the crux of the show. The same could be said for wrestling, as that has various "dramatic" storylines featuring good guys, bad guys, romantic entaglements, etc. Heck, wresting fits the "soap opera" bill much better than most shows actually. They just did a hormone swap and replaced the estrogen with testosterone.
