This review discusses different methods using the transradial approach (TRA) of accessing the native coronary arteries and bypass grafts to optimize the quality of angiographic results and support for interventional procedures. 
Coronary artery aneurysm with dissection is an uncommon presentation of Loeys-Dietz syndrome (LDS). LDS patients who present with unstable clinical syndromes merit special attention given unique pathophysiology derangements associated with this disea…
Subintimal dissection and reentry techniques are widely used in chronic total occlusion (CTO) interventions. We describe 3 CTO cases in which the distal vessel could not be visualized after subintimal crossing, in spite of attempts to decompress the…
Despite rapid progress in device technologies for PFO closure over the past decade, long-tunnel anatomies still constitute a challenge. The present study investigated the performance of a novel in-tunnel device (Flatstent EF; Coherex Medical) in long…
We retrospectively analyzed 207 CTO lesions in 195 patients in a single center between January 2008 and December 2011 and found that over  one-half of CTO lesions can be treated with high success and low complication rates by TRI if the lesions are c…
IABP rupture is a rare complication, with overall reported incidence of 1%. The presented case demonstrates the presence of blood within the IABP driveline, which is a key indicator of rupture. 
We should continue to think broadly in terms of alternative strategies for improving procedural and clinical outcomes in older patients. Bleeding avoidance strategies such as use of low-profile sheaths and careful selection and monitoring of periproc…
This study investigates the natural course of paravalvular regurgitation (PAR) with serial transesophageal echocardiography (TEE) measurements. TEE studies were performed at 30 days and 1 year post TAVI with the self-expanding CoreValve for the treat…
This study compares the clinical outcomes of lesion preparation with rotational atherectomy, plain old balloon angioplasty, or cutting-balloon angioplasty in patients with heavily calcified coronary lesions who were treated with drug-eluting stent im…
Several progressively refined percutaneous devices for patent foramen ovale closure have been recently developed. We describe our single-center experience with the new Gore septal occluder.
