It’s been awhile since the Bruins lost a player for an extended amount of time due to illness or injury. That all changed on Monday as the team announced that Charlie McAvoy will miss at least two weeks following a successful procedure to treat an abnormal heart rhythm.

McAvoy first experienced his condition during the Bruins contest with the Edmonton Oilers on Nov. 26. The talented rookie defenseman was diagnosed with a supraventricular tachycardia (SVT) after further evaluation.

The former Boston University standout played in the team’s next 19 games before missing practice at Warrior Ice Arena on Monday. From Bruins Team Internist Dr. David Finn (via press release).

Charlie McAvoy underwent a successful procedure today at the Massachusetts General Hospital to treat an abnormal heart rhythm.

Following the Bruins game on November 26, 2017, Charlie told team physicians that he experienced heart palpitations during the game. Subsequently he underwent an evaluation, which diagnosed him with a supraventricular tachycardia (SVT). The type of SVT Charlie has is not considered to be dangerous to his health but can recur at any time and causes significant symptoms.

After consultation with team physicians, as well as experts in this type of heart condition, Charlie decided to have the condition treated with a procedure called an ablation. The decision to have the procedure done at this time is due to a high probability of recurrence. During the period from the initial occurrence through Saturday’s game, Charlie was cleared to play by the medical team and was monitored closely.

Fortunately for McAvoy, who will miss at least the two Bruins games before the All-Star break (Tuesday vs. New Jersey and at Ottawa Thursday), it could have been a lot worse.
