Filter by:The skeletonization technique of left internal artery (LIMA) harvesting is reported as more spar-ing to the vascular supply of the sternum. Some studies report a greater length and greater flow of the graft additionally. The aim of our study was to measure the difference in post-op sternal blood supply compared to the pedicle harvesting technique and to measure the length and flow of the LIMA graft.
This study will be an observational registry to investigate the ability of magnetocardiography (MCG) in determining the presence of myocardial ischemia with the absence of obstructive coronary artery disease, by using an invasive reference standard coronary flow reserve (CFR) measured using thermodilution for diagnosis. The device is a magnetocardiography (MCG) scanner named CardioFlux, which is paired with cloud processing software. A CardioFlux scan appointment shall last approximately 15 minutes in duration and include a patient questionnaire following the scan.

Introduction. Ischemic cardiomyopathy is one of the death leading causes in industrialized countries. Up-to-date ESC guidelines recommend a surgical approach (coronary by pass graft) in patients with multivessel coronaropathy, with involvement of left main (LM) or proximal left anterior descending (LAD) artery. In any case, is recommended the use of the internal thoracic artery (ITA) as conduct of choice. In consideration of the very strong evidence supporting the use of ITA, the study objective is to analyze and compare some blood markers collected from ITA blood vs. LAD blood, with the purpose of better understanding the technique benefits from a biological point of view, being the hemodynamic one already evident. Methods. Forty patients scheduled for coronary bypass graft (CABG) surgery at the Cardiac Surgery Unit of European Hospital of Rome will be enrolled. Patients which intervention includes off-pump ITA-LAD anastomosis will be included. For each patient blood sample from ITA and LAD will be collected. On those samples, polymorphonuclear leukocytes and platelets activity, endothelial dysfunction, oxidative stress and inflammatory burden will be analysed. In patients in which a pre-operative coronary CT scan is available, findings will be correlated with atherosclerotic plaque morphology. Expected results. Diseased LAD's blood will have a deranged markers profile compared with ITA's, with augmented inflammatory burden, reduce NO availability and increased platelet activation. In the patients subgroup with available coronary CT scan will be possible to esteem the effective blood mixing and speculate on a possible pharmacological effect of CABG, in terms of dilution of inflammatory burden in the target vessel.
Coronary Microvascular Dysfunction has been consistently shown to play a considerable role in pathophysiology of Ischaemia with non-obstructed coronary arteries (INOCA). While the both diagnoses are individually related to remarkably worse outcome, there is no available method to simultaneously determine INOCA-CMD endotypes in vessel level, during the invasive diagnosis. The investigators hereby hypothesize that, combined intracoronary electrocardiogram (IC-ECG) (considering the high sensitivity and specificity of IC-ECG for studied vessel-territory) and intracoronary doppler can simultaneously and successfully identify vessel specific coronary microvascular dysfunction and resulting ischemia, which may potentially enable immediate diagnosis and endotyping of CMD-INOCA subgroups during the invasive assessment of first ANOCA episode, obviating the need for further ischemia-studies such es SPECT, which have considerably higher costs and lower sensitivity. Major coronary arteries of patients aged between 18 - 75 without obstructing coronary artery disease who have previously documented ischemia with non-obstructed coronary arteries (INOCA) via coronary angiogram and myocardial perfusion scan will be evaluated simultaneously with IC-ECG and intracoronary Doppler during rest and under adenosine induced hyperaemia. Performance of the combined system to identify Coronary Microvascular Dysfunction with structural and functional subgroups as defined by abnormal Coronary Flow Reserve (CFR) and Hyperemic Microvascular Resistance (HMR) and Ischemia in downstream territories of same vessel area (as defined by perfusion scan) is intended to be determined. The investigators also intend to interrogate the possible relationship between dynamic changes in IC-ECG parameters and invasively obtained intracoronary hemodynamic data.
The aim of this study is to assess the impact of culprit-first versus culprit-last percutaneous coronary intervention on the door to balloon time and clinical outcomes in patients with ST-elevation myocardial infarction.
Radial approach is widely established in cardiac diagnostic and therapeutic treatments. It has been shown to decrease bleeding, vascular problems, and mortality rates when compared to the femoral approach. It also offers better comfort to patients through early mobility and lowers hospital expenses. Previously, there were no specific devices for radial artery hemostasis. Many different types of dressings were used in various hospitals with no standardization. This raises the question of whether specific devices surpass dressings in terms of patient comfort, time required to maintain hemostasis, and vascular complications. The primary goal of this study was to examine the effectiveness of compression dressings and hemostatic wristbands on patients undergoing cardiac procedures via radial approach in terms of patient comfort, time required to maintain hemostasis, and vascular problems. The hemostatic wristband TR BandR (Terumo Corporation, Tokyo, Japan) was utilized in one group, while compressive elastic dressing, standardized as 13 threads gauze overlapped, opened, longitudinally pleated once and wrapped, making a 5-cm long cylinder, 1-cm in height, was used in the other.
This study aims to investigate the effect of the pneumatic tourniquet technique on the patients' hemodynamics; heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP).
