Wall Myocardial Infarction (wall + myocardial_infarction)
Selected AbstractsRadiofrequency Catheter Ablation of Postinfarction Ventricular Tachycardia from the Proximal Coronary SinusJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 3 2001JOSEF KAUTZNER M.D., Ph.D. VT Ablation from the Coronary Sinus. Optimum strategy for radiofrequency (RF) catheter ablation of ventricular tachycardia (VT) after inferior wall myocardial infarction (MI) that originates from the posteroseptal process of the left ventricle is not known. We describe a case report of a 57,year-old man who developed recurrent post-MI VT with ECG morphology consistent with this type of VT (i.e., left bundle branch block pattern with predominant R waves from V2 to V6 and left-axis deviation). Endocardial mapping and entrainment during VT demonstrated a critical isthmus of the reentrant circuit in the proximal coronary sinus. RF application terminated VT and rendered it noninducible.

The patient, who had been diagnosed with dextrocardia 3 years prior to this admission, presented with right-sided chest pain. Coronary angiography demonstrated an 80% proximal left anterior descending artery stenosis which was successfully stented. A cardiac MRI was performed to exclude a left atrial thrombus after an inconclusive echocardiogram. The MRI demonstrated findings consistent with dextroversion, with delayed contrast-enhanced viability sequences confirming a near transmural anterior wall myocardial infarct. To our knowledge, this is the first report illustrating the cardiac MRI findings in such a case. [source] Systolic Total Narrowing of Left Anterior Descending Coronary Artery and Flow Interruption Secondary to Myocardial Bridge: A Rare Case Report and Review of LiteratureCLINICAL CARDIOLOGY, Issue 10 2008Fehmi Kacmaz MD Abstract A 33-y-old man was admitted to the emergency department with sudden onset of severe substernal chest pain radiating to the left arm and neck. No pathological signs were recorded upon physical examination. The admission electrocardiogram (ECG) recorded during chest pain showed a large anterior wall myocardial infarction. Intravenous (IV) infusion of 1.5 million units of streptokinase over 1 h was initiated. Coronary angiography revealed total narrowing and flow interruption in the midsegment of the left anterior descending (LAD) coronary artery secondary to a myocardial bridge during systole and disappearance with diastole. He was discharged on aspirin (300 mg/d), metoprolol (100 mg/d), enalapril (10 mg twice daily), and atorvastatin (40 mg/d) treatment at the follow-up period. Copyright © 2008 Wiley Periodicals, Inc.
