Anchor-balloon technique to facilitate stent delivery via the GuideLiner catheter in percutaneous coronary intervention.

AIM: The GuideLiner (GL) is a widely used catheter primarily in complex percutaneous coronary intervention (PCI). Deep seating of the GL and distal stent placement may be facilitated by the anchor-balloon technique (ABT). METHODS: We aimed to prospectively analyze procedural details, technical success, complications and in-hospital outcome in patients who underwent PCI using the GL catheter and the ABT. RESULTS: A total of 118 patients underwent PCI with the aid of the GL and ABT. Procedure success rate was 95% (112/118) and only seven patients (5.9%) encountered complications. ABT was indicated and successfully used in 29 patients (25%). CONCLUSION: GL and ABT successfully aided stent delivery in unfavorable and heavily calcified lesions which otherwise may have been considered unsuitable for PCI.

Pulmonary valve papillary fibroelastoma: a rare tumor and rare location.

Although rare, papillary fibroelastomas (PFEs) are considered the third most common cause of primary cardiac neoplasm. They are usually asymptomatic and are found during routine echocardiography. PFEs of the pulmonary valve are extremely rare. They are usually benign; however, because of their potential to embolize to the pulmonary circulation, it is often recommended that they be removed. This article reviews a case of an asymptomatic PFE of the pulmonary valve, incidentally found in a patient who presented with three-vessel coronary artery disease.

Rapidly progressive coronary artery disease as the first manifestation of antiphospholipid syndrome.

Antiphospholipid syndrome (APS) is an autoimmune multisystem disorder characterised by high incidence of arterial and venous thrombosis. Cardiovascular manifestations also include valvular heart disease, ventricular thrombi and higher risk for coronary artery disease (CAD). In this case report, we describe a 61-year-old woman who had no significant risk factors for CAD, and presented with aggressive disease in native and graft vessels that required multiple coronary interventions. The extent of her aggressive CAD could not be explained by her risk factors profile. Therefore autoantibodies screening was carried out and showed a strongly positive anticardiolipin and ß2 glycoprotein-I antibody, and hence a diagnosis of antiphospholipid syndrome was made.

Modern antiplatelet agents in coronary artery disease.

Dual antiplatelet therapy is well recognized in the prevention of thrombotic complications of acute coronary syndrome and percutaneous coronary interventions. Despite clinical benefits of aspirin and clopidogrel therapy, a number of limitations curtail their efficacy: slow onset of action, variability in platelet inhibitory response and potential drug-drug interactions. Furthermore, the single platelet-activation pathway targeted by these agents allows continued platelet activation via other pathways, ensuring incomplete protection against ischemic events, thus, underscoring the need for alternate antiplatelet treatment strategies. A number of novel antiplatelet agents are currently in advance development and many have established superior effects on platelet inhibition, clinical outcomes and safety profile than clopidogrel in high-risk patients. The aim of this review is to provide an overview of the current status of P2Y12 receptor inhibition and PAR-1 antagonists in determining a future strategy for individualized antiplatelet therapy.

Gigantic unruptured sinus of Valsalva aneurysm presenting as an incidental murmur.

We report a case of a 56-year-old man referred by his family physician with an asymptomatic cardiac murmur. Trans-thoracic echocardiography (TTE) suggested an unruptured right sinus of Valsalva aneurysm (SVA) causing extrinsic compression of the right ventricular outflow tract. This was confirmed with an ECG-gated cardiac CT showing a large right SVA measuring 35×37×42 mm in size. Coronary angiography demonstrated non-obstructive coronary artery disease. Ascending thoracic anterior in the right anterior oblique view delineated the right SVA. The patient underwent aortic valve sparing surgical repair of the aneurysm with an excellent result. Echocardiography confirmed obliteration of the aneurysm and normal aortic valve function postoperatively.
