    Comparison of percutaneous transmitral commissurotomy with Inoue balloon technique and metallic commissurotomy: Immediate and short-term follow-up results of a randomized study
    (AMERICAN HEART JOURNAL, 2002)
    Background The Inoue balloon technique for mitral commissurotomy is well established and carried out worldwide. Metallic commissurotomy is reported to be a cheaper and effective alternative to balloon mitral commissurotomy.Methods One hundred patients were randomized into 2 groups to undergo percutaneous transmitral commissurotomy (PTMC) by means of the Inoue balloon technique (IBMC, n = 49) or metallic commissurotomy (PMMC, n = 51). Patients were crossed over to the other technique when the initial technique was a failure. Success of valvotomy, procedure-related complications, and follow-up events of the 2 techniques were compared.Results Basal echocardiographic and hemodynamic data were similar in both groups. Procedural success was similar in both groups: 45 of 49 procedures (91.8%) in the IBMC group, compared with 46 of 51 procedures (90.18%) in the PMMC group (P = 1.0). Crossover was also comparable, with I occurring in the IBMC group, compared with 3 in the PMMC group. Complications such as cardiac tamponade and mitral regurgitation (requiring or not requiring mitral valve replacement) were similar in both groups, with 3 complications in the IBMC group, compared with 4 complications in the PMMC group (P =.29). After a follow-up period of approximately 4 months, both groups had similar event rates and comparable hemodynamic parameters (P = not significant).Conclusions Both IBMC and PMMC are successful means of providing relief from severe mitral stenosis with a gain in valve area and reduction in transmitral gradient. Both techniques have similar procedural success, complication rates, and follow-up events.

    Left hemothorax: A presentation of a late ventricular perforation caused by an active fixation pacing lead
    (INTERNATIONAL JOURNAL OF CARDIOLOGY, 2010) Bohora, S; Unnikrishnan, M; Kumar, VKA; Nayyar, S; Tharakan, J
    Ventricular perforation, late after ventricular lead placement at the right ventricular apex is rare, and though, commonly presents with chest pain, loss of pacing and/or sensing, and hemodynamic instability caused by cardiac tamponade, it can rarely cause left sided hemothorax needing surgical exploration.

    Post myocardial infarction ventricular septal rupture in a patient with single coronary artery
    (INTERNATIONAL JOURNAL OF CARDIOLOGY, 2002) Kumar, VKA; Harikrishnan, S; Tharakan, JM
    A 52-year-old male developed ventricular septal rupture on the third day after acute anterior wall myocardial infarction. Coronary angiogram showed a single coronary artery (right coronary from left main stem) with significant lesions in left anterior descending and in left circumflex coronary arteries. This association has not been reported so far. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
