Heart valve maker Edwards Lifesciences Corp. said Wednesday its fourth-quarter profit grew 36 percent as sales improved.

Edwards said its profit rose to $64.8 million, or 54 cents per share, from $47.6 million, or 40 cents per share in the year-ago quarter. Excluding one-time charges the company said its profit totaled 55 cents per share. Revenue rose 13 percent, to $392.4 million from $346.7 million.

Analysts had expected a profit of 53 cents per share and revenue of $384.3 million, according to a FactSet survey.

The company said its heart valve therapy revenue grew 20 percent to $226.2 million in the fourth quarter after it launched its Sapien XT valve. Sales of transcatheter heart valves like Sapien grew 87 percent to $65.3 million.
