Key result
Transseptal IVL with PTMC yields a favorable outcome in heavily calcified rheumatic mitral stenosis.
Why the study?
PTMC has the highest success rate in mitral stenosis with minimal calcification and low Wilkins score, while high Wilkins score can preclude successful PTMC.
Case Report (n=1)
Intravascular lithotripsy may serve as a feasible adjunctive technique to facilitate successful percutaneous balloon mitral valvuloplasty in patients with heavily calcified rheumatic mitral stenosis.
Percutaneous transvenous mitral valve commissurotomy (PTMC) is an American Heart Association/American College of Cardiology Class I recommended treatment for rheumatic mitral stenosis with appropriate anatomy. This procedure has the highest rate of success when performed on valves with minimal valvular and subvalvular calcification and an overall low Wilkins score. A high Wilkins score can preclude successful PTMC.1 A recent case report demonstrates a favorable outcome with transseptal intravascular lithotripsy (IVL) using the Intravascular Shockwave Lithotripsy System (Shockwave Medical, Santa Clara, CA) in conjunction with PTMC2 in a patient with heavily calcified rheumatic mitral stenosis.

Chaddha et al. (2021) conducted a case report in Heavily calcified rheumatic mitral stenosis (n=1). Transseptal intravascular lithotripsy (IVL) in conjunction with PTMC was evaluated. Transseptal intravascular lithotripsy (IVL) in conjunction with PTMC yielded a favorable outcome in a patient with heavily calcified rheumatic mitral stenosis.
