    Percutaneous Valvuloplasty for Mitral Valve Restenosis: Postballoon Valvotomy Patients Fare Better Than Postsurgical Closed Valvotomy Patients
    (CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, 2010)
    Aim: To compare the results of percutaneous mitral valvuloplasty (BMV) for mitral restenosis in post-BMV versus postclosed mitral valvotomy (CMV) patients. Methods and Results: Ninety-two patients who underwent BMV for mitral restenosis were followed up prospectively. Of these, 28 patients had undergone previous percutaneous mitral valvuloplasty (PRIOR BMV) and 64 patients had undergone previous closed mitral valvotomy (PRIOR CMV). BMV for mitral restenosis was a success in 59% patients (57.1% PRIOR BMV, 59.3% PRIOR CMV, P = 1.0). Incidence of severe mitral regurgitation was 3.25%, all in the PRIOR CMV group. In univariate analysis, the major predictor of successful BMV for mitral restenosis was Wilkins score (P = 0.004). At a follow up of 3.47 + 2.07 years, mitral valve area was similar between groups (1.45 +/- 0.22, 1.46 +/- 0.26, P = 0.35). The combined end points of mitral valve replacement (MVR), need for rerepeat BMV for mitral restenosis or death was higher in the PRIOR CMV group (31.2% PRIOR CMV, 7.1% PRIOR BMV, P = 0.027). Event-free survival at follow up was lower in the PRIOR CMV group (69% PRIOR CMV, 92.8% PRIOR BMV) mainly due to the higher need for MVR (11 vs. 0 patients, P = 0.03). Conclusions: In conclusion, following BMV for mitral restenosis, patients with PRIOR BMV are found to have lesser event rates on follow-up compared to patients with PRIOR CMV, though procedural success rates are similar.

    Superior vena caval aneurysm.
    (Interactive cardiovascular and thoracic surgery, 2003)
    Venous aneurysms arising from the mediastinal systemic veins are rare. There are only 27 reported cases of such aneurysms. Majority arise from the superior vena cava. We are reporting a saccular aneurysm of superior vena cava in a 58-year-old male. The chest radiogram suggested superior mediastinal mass and the computed tomogram was suggestive of aortic arch aneurysm. Aortography and venography confirmed the diagnosis as saccular aneurysm arising from the superior vena cava. A 7 cm saccular aneurysm arising from the distal half of superior vena cava was resected through median sternotomy. The surgery was done to prevent pulmonary thrombo-embolism.
