Authors: Ranucci M, Baryshnikova E Abstract Minimally invasive extracorporeal perfusion technologies are based on the use of a minimally invasive extracorporeal circulation (MiECC) system. This includes a closed CPB circuit; biologically inert blood contact surfaces; reduced priming volume; a centrifugal pump; a membrane oxygenator; a heat exchanger; a cardioplegia system; a venous bubble trap/venous air removing device; and a shed blood management system. Some of these items, alone or in combination, are able to modify the blood activation usually elicited by cardiopulmonary bypass (CPB). The hemostatic system act...

A blunted heart rate (HR) response during dipyridamole myocardial perfusion imaging has been associated with a poor outcome. To assess the value of HR response in patients undergoing high dose dipyridamole stress echocardiography (SE), we retrospectively selected a sample of 3,059 patients (none with pacemakers or atrial fibrillation; mean age 66 ±11 years). All underwent high dose (0.84 mg/kg) dipyridamole SE for evaluation of known or suspected coronary artery disease and/or heart failure in 2 laboratories of Pisa-IFC and Lucca.

This study evaluated clinical impact of concomitant CAD and coronary revascularization on recurrence of AF after catheter ablation.Methods and ResultsFrom April 2008 to December 2015, 700 consecutive patients were treated with pulmonary vein isolation (PVI) for AF as initial procedure. Of those, 681 patients who simultaneously underwent coronary angiography were investigated. Patients with at least one coronary stenosis ( ≥70%) were classified as having obstructive CAD. Of 681 patients, 90 patients had CAD, and 42 patients underwent percutaneous coronary intervention (PCI) for lesions with perfusion abnormalities on SPE...

3017Objectives: The left ventricular (LV) functional parameters using Anger camera has been reported to be not significantly altered by arrhythmia. The CZT camera that offers high sensitivity and spatial resolution with a novel detectors and reconstruction algorithms has made it possible to measure accurate LV functional parameters. The purpose of this study is to evaluate LV functional parameters by setting different heartbeat acceptance windows on gated myocardial perfusion SPECT (MPS) using CZT camera in patients with arrhythmia whose the heart rate is consistently variable (CV) and atrial fibrillation (AF). Methods: Ga...

ConclusionsThis is the first case of a return of spontaneous circulation after cardiac arrest induced by the intentional ingestion of boric acid and mirtazapine, requiring percutaneous cardiopulmonary bypass for survival. To maintain cerebral perfusion during percutaneous cardiopulmonary bypass, even in a prolonged state of cardiac arrest induced by overdose, is medically, ethically, and economically challenging.

The copeptin/vasopressin system is a manifestation of hypothalamic-pituitary-adrenal-axis activity and may act as an acute compensatory mechanism when there is a disruption in volume-loading homeostasis, i.e. when cardiac stress is evident. Whether DefS will influence ...

Authors: Campbell BC Abstract In recent years, reperfusion therapies such as intravenous thrombolysis and endovascular thrombectomy for ischaemic stroke have dramatically reduced disability and revolutionised stroke management. Thrombolysis with alteplase is effective when administered to patients with potentially disabling stroke, who are not at high risk of bleeding, within 4.5 hours of the time the patient was last known to be well. Emerging evidence suggests that other thrombolytics such as tenecteplase may be even more effective. Treatment may be possible beyond 4.5 hours in patients selected using brain imagi...

Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.
