Distinct Effects of Left or Right Atrial Cannulation on Left Ventricular Hemodynamics in a Swine Model of Acute Myocardial Injury
We examined the effects of right atrial to femoral artery (RA–FA; VA-ECMO) bypass versus left atrial to femoral artery (LA–FA; TandemHeart) bypass using a centrifugal pump (Cardiac Assist Inc, Pittsburgh, PA) on LV hemodynamics in a swine model of acute LV injury. In eight male swine, the RA–FA bypass group employed a 21 Fr inflow cannula in the right atrial (RA) and a 17 Fr FA outflow cannula. The LA–FA bypass group employed a 21 Fr inflow cannula in the LA and a 17 Fr FA outflow cannula. Both pump configurations were activated at 3,500 rotations per minute (RPMs) followed by balloon angioplasty-mediated occlusion...

Energy efficiency and pulmonary artery flow after balloon pulmonary angioplasty for inoperable, chronic thromboembolic pulmonary hypertension: Analysis by phase-contrast MRI
Conclusion Analysis of PA energetics using phase-contrast MRI demonstrates that BPA improves energy loss in CTEPH. In addition, BPA responses can be predicted by PA energy status pre-treatment.

Clinical Outcomes in Diabetic Patients Who Underwent Percutaneous Coronary Intervention during the Plain Old Balloon Angioplasty (POBA)-, Bare Metal Stents (BMS)- and Drug-eluting Stents (DES)-eras from 1984 to 2010.
Conclusion The incidence of 3-year cardiovascular events decreased from 1984 to 2010 in patients with diabetes following PCI, despite the higher risk profiles in the DES-era. PMID: 28049984 [PubMed - in process]

Novel balloon-and-aspiration method for cerebral venous sinus thrombosis: dental-floss technique.
Abstract Cerebral venous sinus thrombosis is sometimes fatal. The standard treatment for sinus thrombosis is anticoagulation, but endovascular intervention must be considered when medical treatment fails. Mechanical thrombectomy is usually required when a large clot burden exits. Unfortunately, in sinus thrombosis attributable to a clot burden larger than that in an intracranial artery, the conventional technique used for intraarterial acute stroke intervention with a stent retriever and/or aspiration is not very effective. The authors describe here their endovascular approach to mechanical thrombectomy for sinus ...

MRI audit of complications in intracranial stenosis treated with Wingspan device
Conclusions ICAS treated by Wingspan stenting using pre-placement balloon angioplasty appears safe and effective with a high technical success rate and favorable outcomes. There is a high incidence of asymptomatic DWI hyperintensites post-procedure, but these do not appear to result in long-term sequelae.

Usefulness of multidetector computed tomography before and after pulmonary vein isolation.
CONCLUSION: In the preprocedural evaluation and postprocedural follow-up of patients undergoing pulmonary vein isolation, MDCT is useful for guiding treatment and detecting complications. PMID: 28457532 [PubMed - as supplied by publisher]

PC164 Fast-Track Thrombolysis for Acute Lower Extremity In-Stent Occlusions: A Novel Approach to Minimize Complications of Standard Thrombolytic Therapy
The role of catheter-directed thrombolysis (CDT) in the treatment of acute lower extremity ischemia may require prolonged periods of time to achieve successful lysis. Prolonged thrombolysis infusion has demonstrated increased incidence of intracranial bleeding, stroke, and local complications. It is expensive and increases hospital length of stay. To minimize these potentially negative outcomes, we developed a fast track approach (FTA) that included the use of aggressive balloon angioplasty and stenting before the thrombus was completely lysed.

The Current Status of Percutaneous Coronary Intervention in Korea: Based on Year 2014 Cohort of Korean Percutaneous Coronary Intervention (K-PCI) Registry.
CONCLUSION: These data may provide an overview of the current PCI practices and in-hospital outcomes in Korea and could be used as a foundation for developing treatment guidelines and nationwide clinical research. PMID: 28567083 [PubMed - in process]

Proatlantal intersegmental artery with internal carotid artery stenosis
A 56-year-old man presented with vertigo of 4 days duration. Neurologic examination was unremarkable. CT angiograms revealed a right internal carotid artery (ICA) stenosis and an ipsilateral proatlantal intersegmental artery (PIA, type 1). The PIA arose from the ICA, ran upward, then took a dorsal course, and continued as the vertebral artery, serving as the major contributor of the posterior circulation (figure, A–C). Catheter-based angiogram showed ICA stenosis of 60% (figure, D). He chose drug therapy and remained asymptomatic on follow-up. Such combination can lead to TIA of the vertebrobasilar system; treatment ...

Immediate and midterm results of balloon angioplasty for recurrent aortic coarctation in children aged < 1 year.
CONCLUSIONS: In this study, percutaneous balloon angioplasty for recoarctation in young infants aged<1 year improved aortic isthmus diameter with a low incidence of adverse event. However, the rate of further intervention is high, and is associated with a smaller balloon size. PMID: 29030063 [PubMed - as supplied by publisher]

E-055 Intracranial angioplasty and stenting with neuroform atlas stent
The SAMMPRIS Trial showed that medical treatment of intracranial stenosis is safer than intracranial angioplasty and stenting (IAS). One of the reasons for the worse outcome with IAS was the occurrence of ipsilateral cerebral hemorrhage, which may be associated with an intracranial exchange maneuver. Newly developed mini intracranial stents may enhance the safety of IAS by obviating the need for this maneuver. We retrospectively evaluated 7 intracranial stenoses (6 patients, 5 men, mean age 57) which were treated with an Atlas stent. In 5 cases there was a high-grade atherosclerotic stenosis which did not optimally respond...

Bringing Robotics into the Cath Lab to Protect Physicians
Percutaneous Coronary Intervention (PCI, or angioplasty with stent) is a common procedure used to treat patients with obstructive coronary artery disease, with an estimated 600,000 procedures performed annually in the United States. PCI has a low risk of complications for patients, but that's not the case for clinicians. Patients receive a dose of radiation during a PCI procedure, which takes anywhere from 30 minutes to a few hours. Interventional cardiologists and cardiac catheterization laboratory personnel are exposed to ionizing radiation all day, every day. Protective measures, such as radiation safety caps, goggles...
