The coronary angiogram showed an ostial subocclusive stenosis of a developed first diagonal branch located just upstream of a subocclusive stenosis of the mid left anterior descending (LAD) coronary artery, occluded distally, and a coronary collateral for LAD from a developed right ventricular branch arising with separate ostia from the right sinus of Valsalva. We discuss the diagnostic interpretation of this coronary anomaly and some aspects regarding the percutaneous treatment of bifurcations. aDivisione di Cardiologia-Laboratorio di Emodinamica, Presidio Ospedaliero SS Annunziata di Sassari, Sassari, Italy bU.O. di Cardiologia, Ospedale ‘San Francesco’ di Nuoro, Nuoro, Italy Received 18 March, 2009 Revised 27 May, 2009 Accepted 6 July, 2009 Correspondence to Dr Giuseppe Talanas, Divisione di Cardiologia, Laboratorio di Emodinamica, Presidio Ospedaliero SS Annunziata di Sassari, Via De Nicola 14, 07100, Sassari, Italy Tel: +39 079 2061521; fax: +39 079 210512; e-mail: firstname.lastname@example.org © 2010 Italian Federation of Cardiology.
