    An Unusual Mediastinal Mass in a Patient with Myocardial Infarction
    (ECHOCARDIOGRAPHY-A JOURNAL OF CARDIOVASCULAR ULTRASOUND AND ALLIED TECHNIQUES, 2013) Kumar, SM; Thajudeen, A
    Achalasia cardiae is a rare esophageal motility disorder of unknown cause, which can remain asymptomatic for a long time. Diagnosis can be missed in view of the frequent absence of pathognomonic clinical signs and symptoms. We present the case of an elderly gentleman, who had achalasia incidentally detected by transthoracic echocardiography during evaluation of coronary artery disease. (Echocardiography 2013; 30: E7-E9)

    Comparative Study on Safety, Efficacy, and Midterm Results of Balloon Mitral Valvotomy Performed With Triple Lumen and Double Lumen Mitral Valvotomy Catheters

    Background: The triple lumen Inoue balloon is routinely used for Balloon Mitral Valvotomy (BMV) in India. Its major limitation is the high cost. The double lumen Accura balloon is less expensive, making it an attractive alternative in the developing countries. The study was meant to assess the safety, efficacy and midterm results of Accura balloon with respect to the Inoue balloon. Patients and Methods: 816 consecutive patients, who underwent elective BMV in this Institute from 1997 to 2003, were included in the study. The data of 487 patients who underwent BMV with Accura balloon was compared with 329 patients who underwent BMV with Inoue balloon. The clinical, echocardiographic, and hemodynamic data of these patients were analyzed retrospectively to assess the safety and efficacy of Accura balloon with respect to the Inoue balloon. Results: Immediate procedural success (93.9% in Inoue group and 91.6% in Accura group p. NS) and complications (6.6% in Inoue group and 5.6% in Accura group p. NS) were comparable between the study groups. The two study population had similar restenosis rate and events at 1 year after BMV. Both balloons could be reused multiple times without compromising on the safety and effectiveness. Accura balloons were less costly than Inoue balloon. The reusability with Accura was slightly more and found to be more cost-effective. Conclusions: Both Accura and Inoue balloon mitral valvotomy balloons are effective in providing relief from hemodynamically significant mitral stenosis in terms of gain in valve area and reduction in trans mitral gradient. Both groups have similar procedural success and complication rates, restenosis, and follow-up events at 1 year. Both balloons could be reused multiple times and Accura balloon is found to be more cost effective. (C) 2012 Wiley Periodicals Inc.

    Immediate and Long-term Results Following Balloon Mitral Valvotomy in Patients With Atrial Fibrillation
    (CLINICAL CARDIOLOGY, 2012) Nair, KKM; Pillai, HS; Thajudeen, A; Krishnamoorthy, KM; Sivasubramonian, S; Namboodiri, N; Sasidharan, B; Ganapathy, S; Varaparambil, A; Titus, T; Tharakan, J
    Background: The purpose of this study was to examine the influence of atrial fibrillation (AF) on the immediate and long-term outcome of patients undergoing balloon mitral valvotomy (BMV). Hypothesis: Patients with atrial fibrillation fair poorly after balloon mitral valvotomy. Methods: There were a total of 818 consecutive patients who underwent elective BMV in this institute from 1997 to 2003, with either double-lumen or triple-lumen BMV catheters included in the study. Of them, 95 were with AF. The clinical, echocardiographic, and hemodynamic data of these patients were compared with those of 723 patients in normal sinus rhythm (NSR). Immediate procedural results and long-term events were compared between the 2 study groups. Results: Patients with AF were older (39.9 +/- 9.9 years vs 29.4 +/- 10.1, P < 0.001) and presented more frequently with New York Heart Association (NYHA) class III-IV (53.7% vs 32.9%, P < 0.001), echocardiographic score >8 (47.4% vs 24.9%, P < 0.001), and with history of previous surgical commissurotomy (33.7% vs 11.5%, P < 0.001). In patients with AF, BMV resulted in inferior immediate and long-term outcomes, as reflected in a lesser post-BMV mitral valve area (1.3 +/- 0.4 vs 1.6 +/- 0.4 cm2, P = 0.032) and higher event rate on follow-up. Conclusions: Patients with AF were older, sicker, and had advanced rheumatic mitral valve disease. They had a higher incidence of stroke, new onset heart failure, and need for reinterventions on long-term follow-up. These patients need intense and more frequent follow-up. Clin.

    Left sympathetic cardiac denervation in managing electrical storm: acute outcome and long term follow up
    (JOURNAL OF INTERVENTIONAL CARDIAC ELECTROPHYSIOLOGY, 2016) Prabhu, MA; Prasad, SBV; Abhilash, SP; Thajudeen, A; Balasubramoniam, KR; Namboodiri, N
    Left sympathetic cardiac denervation (LSCD) may be beneficial in treating electrical storm (ES) of varied aetiologies. The present study analyse the outcome and long term follow up of LSCD in treating ES. This is a retrospective study of patients with ES who underwent LSCD. Nine patients (majority males (88.89 %), median age 52 years, IQR 50.5-56.5) underwent LSCD. Coronary artery disease was the commonest substrate (7 (77.78 %)). Five patients, who had hypotension and unstable hemodynamics, underwent percutaneous stellate ganglion blockade. Three of the survivors subsequently underwent surgical sympathectomy. In the remaining four, video assisted thoracoscopy (VATS) guided sympathectomy was performed. Five (55 %) and seven (77.78 %) had a > 90 and 80 % reduction in ventricular arrhythmias (VA), respectively. LSCD was ineffective in one patient, who succumbed to ES. There was no difference in outcome between patients with monomorphic versus polymorphic VA (60 vs 70 %, respectively, p = 0.82). One (11.1 %) patient had sudden death on the fifth day after LSCD. The median hospital stay was 13 days (IQR 11-16). During median 34 months of (IQR 18-46) follow up, one patient died of heart failure, and another had recurrence of ES. There was sustained reduction in VA burden in others. LSCD is effective in controlling ES and continues to reduce the incidence of VAs during long term follow up. Pharmacological LSCD needs particular emphasis, as it can be performed at bedside, and can be a bail-out procedure in centres where sophisticated procedures like VATS-guided LSCD or radiofrequency ablation are not readily available.

    A 50-year-old female presented with incessant palpitation of 2 weeks duration. She was hemodynamically stable and there was no evidence of heart failure. A transthoracic echocardiogram showed mild left ventricular (LV) dysfunction with LV ejection fraction of 45%. Electrocardiogram (12 lead and rhythm strip) was taken during the palpitation. What is the mechanism?

    A 50-year-old woman underwent radiofrequency catheter ablation of narrow QRS tachycardia that was terminated with intravenous adenosine. Twelve-lead electrocardiogram was normal during sinus rhythm. The electrophysiological study showed normal atriohisian and hisioventricular intervals during sinus rhythm. Atrial burst pacing reproducibly induced two narrow QRS tachycardias. Figure 1 shows spontaneous switch of tachycardia 1 to tachycardia 2. What are the likely mechanisms of the tachycardia and the transition?

    Persistent Atrial Standstill in Acute Myocarditis
    (INDIAN PEDIATRICS, 2016) Prabhu, MA; Prasad, BVS; Thajudeen, A; Namboodiri, N
    Background: Atrial standstill manifests as absence of any atrial electrical activity in the surface ECG leads. Persistent atrial standstill secondary to acute myocarditis is extremely rare. Case report: 10-year-old girl had atrial standstill and heart failure due to acute myocarditis. After recovery from myocarditis, heart failure resolved, but the atrial standstill persisted. Outcome: Persistent atrial standstill was treated with permanent pacemaker and anticoagulation. Message: Acute myocarditis may rarely cause atrial standstill that can last even after recovery from myocarditis.
