We report a 5-year-old boy weighing 11 kg, with severe mitral valve stenosis of rheumatic aetiology, who underwent successful percutaneous transluminal mitral commissurotomy (PTMC) with valvuloplasty balloon. Postprocedural mean pressure gradient across the mitral valve decreased to 6 mmHg from an initially recorded value of 22 mmHg. In addition to symptomatic improvement, the mitral valvular area increased from 0.4 to 0.8 cm(2) without significant change in mitral regurgitation. At 1- and 3-month follow up, transthoracic echocardiography revealed further improvement with an increase in mitral valve area to 1.0 cm(2), a decrease in pulmonary arterial pressure, and a mean mitral valve pressure gradient of 8 mmHg with trivial mitral regurgitation. To best of our knowledge, this is the first successful PTMC procedure performed in the youngest and smallest ever reported child with rheumatic mitral stenosis (MS). We conclude that PTMC with valvuloplasty balloon could be a logical alternative to surgery in young patients with rheumatic MS.
