Abstract: Popliteal artery morphology changes while undergoing knee motion. A main flexion (i.e., the ‘hinge point’) and other flexions (termed ‘accessory flexions’) were described as a result of popliteal artery adaptation to knee flexion. Knee dyna…
Abstract: Implantation of two or more adjacent-sequential stents is frequently required during coronary interventions, especially when treating long lesions.  We present two cases illustrating that plain fluoroscopic imaging may be misleading when us…
You can liken performance of high-risk percutaneous coronary intervention (PCI) to attempting to repair a damaged car engine while it is turned on. Moreover, that car is trying to slowly drive away from a steep cliff with the ocean crashing at its ba…
Abstract: Background. Intra-aortic balloon pumps (IABPs) are indicated during high-risk percutaneous coronary intervention (HR-PCI) to reduce major procedural complications. The clinical utility of the newer Impella and TandemHeart devices is not cle…
Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia, increasing in occurrence with age. Based on recent epidemiology, it is estimated to affect 6.1 million Americans, and this number is likely to increase to 15.9 million by 20…
Abstract: Purpose. Radiofrequency ablation (RFA) is an established therapy for the treatment of paroxysmal and persistent atrial fibrillation (AF). Many techniques have been reported to achieve RFA. We report a single-center experience of RFA using t…
Many clinicians across the world have adopted the transradial approach for coronary angiography and percutaneous coronary intervention (PCI).1,2 Reduced vascular complications, early ambulation, patient satisfaction, and reduced procedural costs are…
Abstract: Objectives. This study used intravascular ultrasound (IVUS) to evaluate radial artery volume changes after intra-arterial administration of nitroglycerin and/or verapamil. Background. Radial artery spasm, which is associated with radial art…
The optimal revascularization strategy for emergent left main coronary artery (LMCA) in the setting of acute coronary syndrome (ACS) remains largely an unresolved issue. The most current ACC/AHA 2009 Focused Update Guidelines assign it a IIb recommen…
Abstract: Background. Unprotected left main (ULM) coronary disease is considered by contemporary guidelines a class I indication for surgery. However, percutaneous coronary intervention (PCI) is often carried out in the ULM in either emergent or high…
