1/12. Transluminal extraction catheter atherectomy for the treatment of acute occlusion of an ectatic coronary artery.

    Thrombotic occlusion of an ectatic coronary artery may not respond to thrombolytic therapy or balloon angioplasty, since the infarct-related vessel contains a significant amount of thrombus. A patient with acute myocardial infarction of an ectatic right coronary artery that was occluded by a heavy clot burden is described. The patient was treated successfully with transluminal extraction catheter atherectomy and results were confirmed by intravascular ultrasound.

2/12. Laser-facilitated thrombectomy: a new therapeutic option for treatment of thrombus-laden coronary lesions.

    To overcome the adverse complications of balloon angioplasty in thrombus burden lesions (i.e., distal embolization, platelet activation, no-reflow phenomenon with persistent myocardial hypoxemia), mechanical removal of the thrombus or distal embolization protection devices is required. Pulsed ultraviolet excimer laser light at 308 nm can vaporize thrombus and suppress platelet aggregation. Clinical experience has already shown its efficacy in acute ischemic-thrombotic acute coronary syndromes. Unlike other thrombectomy devices, a 308 nm excimer laser can ablate thrombi as well as the underlying plaque, speed up thrombus clearing, and enhance thrombolytic and GP IIb/IIIa activity. It can also be employed in patients with contraindications for systemic thrombolytic agents or GP IIb/IIIa antagonists. Our report covers clinical data and technical aspects concerning three patients with acute myocardial infarction who presented with a large thrombus burden. After successful laser-transmitted vaporization of the thrombus mass in these patients, the remaining thrombus burden was evacuated, and normal antegrade coronary flow was successfully restored. This approach can be useful for selective patients with acute coronary syndromes.

3/12. Embolization containment device for a native coronary arterial lesion with large thrombus burden.

    Distal embolization and no reflow, resulting in myocardial infarction, are frequently observed during percutaneous coronary intervention in lesions with large thrombus burden. This case report describes the successful treatment of a lesion with large thrombus burden with an embolization containment device.

4/12. Power thrombectomy in acute ischemic coronary syndromes.

    Intracoronary thrombi are commonly found in patients with acute coronary syndromes. A large thrombus burden or a platelet-rich thrombus frequently resists pharmacologic therapy ("thrombolytic ceiling"). In such cases restoration of adequate antegrade coronary flow necessitates application of a mechanical force. Power thrombectomy is a revascularization strategy incorporating a mechanical device for removal of occlusive coronary thrombi in conjunction with or following administration of either platelet glycoprotein IIb/IIIa receptor inhibitors or thrombolytic agents, or both. Mechanical devices for power thrombectomy include ultrasound sonication, rheolytic thrombectomy (Angiojet), laser, transluminal extraction catheter, aspiration catheter, and to a limited extent, balloon angioplasty. In acute coronary syndromes the strategy of power thrombectomy aims to achieve the clinical advantages of more nearly complete vessel patency, improved antegrade flow, and enhanced preservation of myocardial tissue.

5/12. A case of paradoxical embolism "in situ" associated with massive pulmonary embolism: role of echocardiography.

    A 49-year-old man was admitted in transfer for further management of a pulmonary embolism (PE) and possible mitral valve vegetation. Transthoracic echocardiography performed at our institution showed evidence of right ventricular (RV) enlargement and dysfunction. Within the right atrium was a serpentine mobile thrombus which traversed the interatrial septum at the level of the fossa ovalis and extended into the left atrium to the level of the anterior mitral valve leaflet. Because of the patient's dyspnea, RV dysfunction, and large clot burden, thrombolytic therapy was considered and would have been administered had the thrombus in situ not been identified. In light of the thrombus in situ and the concern about possible systemic embolization with thrombolytic therapy, the patient underwent successful surgical thrombectomy. This case highlights the importance of echocardiography in the management of patients with PE. We believe that all patients should undergo echocardiography prior to receiving thrombolytic therapy for pulmonary emboli. Careful interrogation of the interatrial septum for the presence of a thrombus in situ is warranted. thrombectomy should be considered in individuals with PE who have a thrombus in situ.

6/12. Late coronary stent thrombosis associated with exercise testing.

    We report a case of coronary stent thrombosis that occurred 6 months after the primary stenting of the left anterior descending coronary artery for acute myocardial infarction in a 75-year-old man. The reinfarction occurred the day after the demonstration of persistent optimal result of the percutaneous coronary intervention and immediately after exercise testing. A combined approach of a mechanical thrombus burden reduction by using AngioJet thrombectomy with adjunctive glycoprotein IIb/IIIa antagonist was performed, resulting in the complete removal of filling defects on the angiography.

7/12. The thrombus laden coronary artery--forget the fancy stuff, just aspirate it!

    "No-reflow" is an important complication of percutaneous coronary intervention (PCI) in the setting of acute myocardial infarction and is associated with worse outcomes. Visible thrombus on the angiogram is a significant risk factor for "no-reflow". A variety of strategies have been employed to prevent this phenomenon including intracoronary vasodilators and distal protection systems. Randomized trials have not revealed any superiority of distal protection devices despite the theoretical rationale to their use. We describe a case of a thrombus-laden right coronary artery in which PCI would have likely resulted in significant "no-reflow". A simple aspiration catheter was used to significantly reduce the thrombus burden. Subsequent stenting was performed with no adverse events. This case illustrates the benefit of a less fancy approach to the thrombus-filled coronary artery - just aspirate it! Randomized trials are needed to test the role of simple aspiration prior to stenting in thrombus-laden coronary arteries.

8/12. Persistent and proximal migration of a large coronary thrombus during percutaneous coronary intervention in the setting of acute Q-wave myocardial infarction.

    We describe a patient with an acute inferior myocardial infarction. Patient was taken to the cardiac catheterization laboratory for primary angioplasty. angiography revealed 100% occluded proximal right coronary artery (RCA). After initial balloon angioplasty of the occluded RCA, a very large mobile thrombus was seen in the proximal RCA. Despite multiple stenting, suctioning through the guide catheter lumen, and intracoronary thrombolytic therapy, the thrombus persisted and migrated proximally after each stenting. However, patient did well despite of persistent large thrombus burden in the proximal RCA on aggressive antithrombotic treatment.

9/12. Successful utilization of a novel aspiration thrombectomy catheter (Pronto) for the treatment of patients with stent thrombosis.

    Stent thrombosis is a rare but catastrophic complication of percutaneous coronary intervention (PCI). thrombolytic therapy is ineffective for the treatment of patients with stent thrombosis, while primary PCI in such patients is limited by a high thrombus burden in the culprit vessel often leading to distal embolization and extensive tissue infarction. We present three patients with stent thrombosis successfully treated with the adjunctive use of a novel and new aspiration thrombectomy device (Pronto).

10/12. Spontaneous late thrombolysis of an occluded saphenous vein graft subsequent to acute myocardial infarction treated with percutaneous coronary intervention to the native culprit vessel.

    A 67-year-old male with prior history of myocardial infarction and coronary artery bypass grafting (individual vein grafts to the left anterior descending artery [LAD] and right coronary artery) presented with an acute anterior ST elevation myocardial infarction and cardiogenic shock. The vein graft to the LAD was occluded with heavy thrombus burden and there was severe native CAD. Given the degree of thrombus burden and other anatomic considerations, percutaneous intervention with stenting was performed to the native proximal LAD. Three months later, after complaining of atypical chest pain, repeat angiogram revealed a spontaneous widely patent vein graft to the LAD and occluded proximal LAD.
