Abstracts From Complex Cardiovascular Catheter Therapeutics (C3) Advanced Endovascular and Coronary Intervention Global Summit
Complex Cardiovascular Catheter Therapeutics (C3) Advanced Endovascular and Coronary Intervention Global Summit is an annual conference that addresses educational needs in the diagnosis and treatment of peripheral arterial, carotid, venous, coronary…
Rotational Atherectomy in the Era of Cost Containment
Interventional cardiologists are frequently asked to reduce procedural costs, and devices that are initially thought to be more expensive can sometimes reduce overall costs. This was the case at our institution with direct Rotawire and rotational ath…
Transcatheter Closure of Five Atrial Septal Communications in the Presence of Severe Pulmonary Arterial Hypertension and Severe Left Ventricular Non-Compliance
We describe a hemodynamic conundrum in a patient with five septal communications in whom the coexistence of unmasked bidirectional physiologic shunting, severe pulmonary arterial hypertension, and worsening left-sided overload dissuaded initial closu…
The Clinical Implications of Balloon Rupture During Cardiovascular Interventions
Balloon rupture is an infrequent complication of cardiac catheterization that can lead to vessel injury. We report 6 cases that highlight the potential consequences of balloon rupture, including perforation, dissection, balloon entrapment, and distal…
First Optical Coherence Tomography Follow-up of Coronary Bifurcation Lesions Treated by Drug-Eluting Balloons
Percutaneous bifurcation intervention with provisional bare-metal stent (BMS) implantation followed by drug-eluting balloon (DEB) treatment represents a valuable opportunity in patients not compliant with long-duration dual-antiplatelet therapy. This…
Forearm Arterial Anatomy and Flow Characteristics: A Prospective Observational Study
Morphometric data on Caucasian radial and ulnar arteries are limited, with no data on flow interdependence in the forearm arterial circuit. We evaluated 250 upper extremities in 125 patients, performing ultrasonography to measure and compare radial a…
Comparison of Fluoro and Cine Coronary Angiography: Balancing Acceptable Outcomes With a Reduction in Radiation Dose
Use of last fluoro hold (LFH) mode in fluoroscopy, which enables the last live image to be saved and displayed, could reduce radiation during percutaneous coronary intervention when compared with cine mode. This is the first study to compare coronary…
The Association Between the Extent of Coronary Artery Disease and Major Bleeding Events After Percutaneous Coronary Intervention: From the ACUITY Trial
The relationship between the extent of coronary artery disease (CAD) and bleeding after PCI remains understudied. This study sought to evaluate the relation between the extent of CAD and bleeding risk in patients undergoing PCI for non-ST segment ele…
Commentary: Differential Hemodynamic Profile of High-Capacity Intraaortic Balloon Pumps – New Promise for an Antiquated Technology?
IABPs likely still have a role in the management of high-risk patients with and without cardiogenic shock. The 50 cc balloon appears to offer both an enhanced as well as more consistent hemodynamic response when compared with the 40 cc balloon; wheth…
Hemodynamic Effects of Standard Versus Larger-Capacity Intraaortic Balloon Counterpulsation Pumps
Several recent trials have examined the clinical utility of intraaortic balloon counterpulsation pumps (IABPs) in cardiogenic shock and acute coronary syndromes. More recently, a larger-capacity 50 cc IABP was introduced into practice. This study exp…
