Aim Percutaneous transluminal septal myocardial ablation (PTSMA), a non-surgical intervention to treat hypertrophic cardiomyopathy (HCM), has been a standard treatment in developed countries. However, this procedure not yet systematically performed in Indonesia. This case series aim to study feasibility, safety and efficacy of PTSMA in National Cardiovascular Center Harapan Kita, Jakarta.Methods Three HCM patients (2 male) with dynamic left ventricle outflow tract (LVOT) pressure gradient of higher than 30 mmHg underwent PTSMA. Left ventricle apex pressure was measured using multipurpose catheter and aortic pressure was measured by means of left coronary guiding catheter simultaneously. Target vessel is confirmed by myocardial echocardiography contrast. Two ml absolute alcohol delivered to the target vessel by means over the wire balloon. Immediate pressure gradient changed 10 minute after alcohol administration was recorded. Continuous ECG monitoring is attemted along the procedure.Results All subject demonstrated more than 50% LVOT pressure gradient reduction. One subject experienced transient total AV block and right bundle branch block which completely recovered 6 hours after procedure. In one patient, target vessel must be changed as it gives perfusion to extensive area of right ventricle.Conclusion PTSMA guided with myocardial echocardiography contrast is feasible, safe and effective to reduce LVOT pressure gradient in HCM patient.

Palpitation is a common presenting symptom in the emergency department. Wolf-Parkinson White (WPW) syndrome is a cardiac conduction disorder that may present with palpitation and lead to sudden cardiac death. WPW could be detected byÂ electrocardiogram (ECG). In this case report, we present two young male patients with WPW syndrome admitted to our hospital with history of repeated and progressive palpitation. ECG of the first patient revealed supraventricular tachycardia which converted to sinus rhythm after propanolol treatment. ECG showed sinus rhythm with delta wave in lead II,III,aVF, V1 suggesting the presence of accessory pathway (AP) in left lateral wall. Electrophysiology study confirmed the presence of AP and radio frequency catheter ablation was successfully done resulted in disappearance of delta on outpatient clinic ECG. Patient has no symptom and he do not have to take medication. ECG of the second patient revealed supraventricular tachycardia with abberancy. After amiodarone infusion, ECG showed sinus rhythm with delta wave in lead I,II,aVL suggesting the presence of accessory pathway in anteroseptal wall. Electrophysiology study and catheter ablation did not perform for this patient because of financial problem, however amidarone has to be taken regularly to prevent the recurrence of supraventricular tachycardia.

Aim AF is the most common arrhythmia in clinical practice and associated with an increased long-term risk of stroke, heart failure, and all-cause mortality. Catheter ablation of AF is relatively new modality to convert AF to sinus rhythm. This study was aimed to elaborate efficacy of catheter ablation in mixed type of AF.Methods Thirty patients (age of 52 Â± 8 yo) comprised of 19 paroxysmal and 11 chronic AF underwent radiofrequency catheter ablation guided by electroanatomical CARTOâ¢ mapping system. We used step wise ablation approach with circumferential pulmonary vein isolation (PVI) as a cornerstone. Additional ablation comprised of roof line, mitral isthmus line, complex fractionated atrial electrogram (CFAE), septal line and coronary sinus ablation was done respectively if indicated. All patients were followed up to 1 year for AF recurrence.Results Circumferential PVI was successfully performed in all patients but one. Average follow up period was 11.5 months. More than 80% of all patients remain in sinus rhythm at the end of follow period which 62% of them were free from any anti-arrhythmic drug. No major complication in all patients series.Conclusion Radiofrequency ablation guided with electroanatomical mapping is effective and safe in mixed type of AF.
