ABSTRACT: We report a case of inferior vena cava filter migration to the right ventricle resulting in ventricular tachycardia and elevated troponin. The patient was taken to the cardiac catheterization laboratory and under fluoroscopy the filter was…
ABSTRACT: Background. Optical coherence tomography (OCT) has been increasingly used to evaluate stent apposition following implantation. Since stent struts are visualized as linear structures with strong surface reflection and typical dorsal shadowin…
TITLE: Long-Term Outcomes of Plaque Debulking with Rotational Atherectomy in Side-Branch Ostial Lesions to Treat Bifurcation Coronary Disease ABSTRACT: Background. The prognosis after rotational atherectomy of a side-branch ostium to treat bifurcati…
In current interventional cardiology practice, the treatment of coronary bifurcation lesions remains among the few technically challenging fields. It is estimated that bifurcation lesions comprise 15–20% of all percutaneous coronary intervention (PCI…
ABSTRACT: Background. To assess the optimal percutaneous coronary intervention (PCI) approach for coronary artery bifurcation lesions (CBL), we conducted a meta-analysis of randomized trials comparing provisional stenting (PS) to complex stenting st…
ABSTRACT: Objective. We used intravascular ultrasound (IVUS) and virtual histology (VH) to assess the differences of plaque burden and composition between target coronary arteries containing the culprit lesion and non-target coronary arteries. Method…
Cardiac computed tomography (CT) has evolved rapidly over the last 20 years. Not long ago, the only proven utility of cardiac CT was the “mammogram of the heart,” allowing risk stratification and identification of early atherosclerosis.1 As the techn…
Impact of Multislice Computed Tomography to Estimate Difficulty in Wire Crossing in Percutaneous Coronary Intervention for Chronic Total Occlusion ABSTRACT: Background. Percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) rema…
ABSTRACT: Objective. We sought to clarify the mechanisms of backup force for right coronary artery intervention. Background. Backup force of a guiding catheter is important for successful percutaneous coronary intervention (PCI); however, little atte…
ABSTRACT: Surgical myocardial revascularization (CABG) in patients with unprotected left main coronary artery disease (ULMCA) is a Class I recommendation in the AHA/ACC guidelines, however it is associated with increased perioperative risk in non-ST…
