Filter by:The goal of this clinical trial is to compare del Nido and Bretschneider-HTK (HTK) cardioplegia solutions in patients undergoing elective aortic valve replacement. The main question it aims to answer is: • Does the del Nido cardioplegia provide better cardioprotection and clinical outcomes than HTK cardioplegia? Participants will receive one of the investigated cardioplegia solutions according to the randomization. Researchers will compare both groups in terms of cardioprotection (described as levels of CK-MB and hsTnI), in-hospital clinical outcomes, biochemical changes in coronary sinus blood and one-year follow-up.
The objective of this study is to investigate the incidence of death and early postoperative complications, identify potential risk factors, and examine the demographic characteristics of patients and epidemiology of cardiovascular procedures. Our hypothesis is that gaining a more comprehensive understanding of the characteristics of patients who undergo cardiac surgery has the potential to improve outcomes for this patient profile. Thus, information was sought regarding the patient characteristics, surgeries performed, anesthesia administered, incidence of intraoperative and postoperative complications, and risk factors associated with complication and mortality in the ICU. The main questions it aims to answer are: - Incidence of mortality or severe postoperative complications that occur within the first 3 postoperative days or until discharge from the ICU. - Risk factors associated with severe complications in patients who undergo cardiac surgery. - Characteristics of patients, anesthesia and surgical procedures performed - Incidence of severe intraoperative complications and moderate postoperative complications - Evaluate the influence of accumulated fluid balance on outcomes, mortality, and length of ICU stay. - Evaluate mortality in the ICU. - Describe the risk factors associated with mortality.
Authors hypothesize that "no-touch" saphenous vein as I graft is superior over conventional "no-touch" saphenous vein as free graft in the incidence of graft patency.
To establish if the cardiac radiation dose assesment is well aproximated with routine 3D CT scan compared to 4D CT experimental scan with respiratory gating (breath motion monitoring). The study population relates to left side breast cancers female patients that require a radiation therapy treatment.
The purpose of this study to determine the prognostic value of the Selvester QRS score for perioperative myocardial injury following elective non-cardiac surgery.
Prospective, interventional, multicentre, non-randomized, single-arm open-label study that aims to enroll 200 consecutive patients with suspected chronic ischemic heart disease in the absence of obstructive coronary artery disease (INOCA) at clinically indicated coronary angiography in 3 Italian centers. During coronary angiography, these patients will be simultaneously subjected to a functional and coronary physiology study (according to the methods reported below): - Functional evaluation with fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), Resting Full-Cycle Ratio (RFR) of angiographic stenosis> 50%; - In the presence of coronary angiographic stenosis <50% or> 50% but in the presence of a negative functional assessment (FFR> 0.80 and iFR / RFR> 0.90), coronary flow reserve (CFR) and index of microvascular resistance (IMR) will be measured. IMR and CFR will be assessed using intra-coronary guidance; - In the presence of CFR> 2.0 and IMR <25, tests with acetylcholine will also be performed in order to evaluate the possible presence of epicardial (focal or diffuse) or microvascular spasm.
A single-center, prospective, randomized, open-label, blinded end-point clinical trial of instantaneous wave-free ratio (iFR) guidance strategy impact on clinical outcomes in multivessel acute coronary syndrome (ACS) patients.
After lung resection, troponin elevation may be regulated by mechanisms other than myocardial ischemia. Perioperative natriuretic peptides measurement may help identify changes in ventricular function during thoracic surgery. Integrating both cardiac biomarkers may improve the predictive value for cardiovascular complications after lung resection.
This study is a prospective, diagnostic, cohort study within the standard care of acute coronary syndrome (ACS) patients. It compares the analytical performance of Siemens® point-of-care high sensitive troponin I testing in venous, plasma and capillary sample types. The investigators hypothesize that there is a good correlation between the Siemens® POC HS cTnI assay results for the three sample types and that the bias between different POC sample types reduces from ~10% to ≤ 5% when using heparinized transfer device for the capillary sample.
This randomised, controlled clinical trial aims to evaluate the safety and efficacy of Cardiac Shockwave Therapy (CAST-HF) in patients with ischaemic heart failure requiring surgical revascularization. The main questions to answer are: - Does cardiac shockwave therapy, in addition to CABG surgery, improve left ventricular ejection fraction? - Is cardiac shockwave therapy in addition to CAGB surgery safe? Participants will be randomised into intervention (cardiac shockwave therapy) and control (sham treatment with an inactive applicator) groups.
