“…Maddoux described successful left main coronary artery embolectomy during cardioplegia with transverse aortotomy, using a Fogarty catheter [3]. The failure of balloon angioplasty to establish patency at the site of the embolus may not be surprising in this case.…”

A 35-yr-old woman with known valvular heart disease presented with acute myocardial infarction. Angiography demonstrated a totally occluded distal left anterior descending coronary artery. Though initially successful, angioplasty ultimately failed to maintain arterial patency, leaving a more distal total occlusion after several balloon inflations. In spite of this, PTCA possibly provided a more localized infarction via a peripheral mobilization of the embolus.

“…This argument was further strengthened when an intracardiac thrombus was visualised on the patient's follow-up echocardiography 2 months later. Maddoux et al 6 reported a similar case of LMCA embolus in which the aetiology was unclear but was likely related to cardiomyopathy with mural thrombus.…”

A case of left main coronary artery embolus further embolising to the left anterior descending artery

SUMMARYCoronary embolism is an uncommon cause of myocardial infarction. The usual source of a coronary embolus is an intracardiac thrombus or vegetation. Embolisation to the left main coronary artery is an extremely rare event and is usually fatal. We present a case of a 38-year-old woman with embolisation to the left main coronary artery which further embolised distally to the left anterior descending artery leading to a non-ST elevation myocardial infarction. The non-occlusive nature of the left main coronary artery embolus might have led to a favourable prognosis in our patient. BACKGROUND

“…The usual pathophysiological substrate of LMCAT is fibrous cup rupture of an atherosclerotic plaque followed by thrombus formation [2]. However, other predisposing factors include hypercoagulable state, post-partum state, embolization of intracardiac masses, cocaine-induced plaque rupture and vasospasm [2, 5]. …”

“…Manual thrombus aspiration in LMCAT has been previously described as a promising therapeutic technique, although data remain sparse [5, 12–14]. Maddoux et al were the first to introduce the thrombus aspiration technique as a standalone treatment in a patient with LMCAT complicated with STEMI who followed an uneventful clinical course at 24-month follow-up [5].…”

“…Maddoux et al were the first to introduce the thrombus aspiration technique as a standalone treatment in a patient with LMCAT complicated with STEMI who followed an uneventful clinical course at 24-month follow-up [5]. Promising results from manual thrombus aspiration were also described by Bhindi et al in a patient with LMCAT presenting as STEMI after CABG [12].…”
