Is percutaneous balloon mitral valvuloplasty under echocardiography guidance only feasible, safe, and effective in patients with severe isolated mitral stenosis?
Percutaneous balloon mitral valvuloplasty guided solely by echocardiography appears feasible and safe, offering an effective treatment for severe mitral stenosis while avoiding radiation and contrast exposure.

May support echo-only balloon mitral valvuloplasty as radiation-free option; hypothesis-generating case series requiring prospective validation.
OBJECTIVE: Percutaneous balloon mitral valvuloplasty (PBMV) is the treatment of choice in patients with isolated mitral stenosis. This study aimed to assess the feasibility of PBMV under echocardiography guidance only of isolated mitral stenosis (MS). METHODS: From October 2016 to Dec 2017, 20 consecutive patients with severe MS underwent PBMV with echocardiography as the only imaging modality at a single center. Outpatient follow-up including chest radiography, electrocardiography, and transthoracic echocardiography was conducted at 1, 3,6, and 12 months after the procedure. RESULTS: ) and mean transmitral pressure gradient low (6.07 ± 1.03 mm Hg). No pericardial effusion or peripheral vascular complications occurred. CONCLUSION: In this small experience, PBMV could be successfully performed under only echocardiography guidance and appeared safe and effective while avoiding radiation and contrast agent use.
