No, there are no ECSA review guides that exist to my knowledge.
However, the ECSA is more like an "extension" to CEH than it is an entirely new exam. The reason being is that the CEH is meant to introduce you to the ridiculous amount of tools that it covers, and get you using them. The ECSA is more on understanding the output of those tools.
Now, I'd imagine that when you used them in CEH, you wanted to understand what the results were. You probably weren't just running 'nmap -v 192.168.1.2', seeing that it displayed some output, and then closing it. My guess was that you looked at the results of that scan to understand what it was displaying. This is the primary idea of the ECSA exam.
In other words, if you did alright on CEH, you should pass ECSA. You can use the same study guide for review.
