The "RIALTO-PRO" study aims to optimize the diagnostic and therapeutic algorithm for myocardial bridge (MB) patients, testing the diagnostic value of a full invasive diagnostic procedure, and, consequently, the prognostic value of a tailored approach. the study objective is to determine the diagnostic and prognostic value of a full-physiology approach strategy versus a standard approach strategy in patients with a MB. The "RIALTO PRO" study is a randomized, multicentre, prospective, open-label, superiority trial comparing a personalised versus standard management in patients with MB. Consenting and eligible patients will be randomised 1:1 to either a "full-physiology approach", consisting of a comprehensive diagnostic algorithm aimed at unmasking the main pathophysiological mechanism of myocardial ischemia and consequently a tailored treatment, or a "standard approach", consisting of angiographic evaluation of the tunnelled segment.
Myocardial bridge (MB) is a congenital anomaly of epicardial circulation characterized by an intramural course of a coronary segment. This anatomical arrangement causes the artery to be squeezed during systole potentially causing flow impairment and ischemia. For this study, MB is defined as the presence of systolic compression in an epicardial vessel causing at least 50% of caliber reduction from diastole. MB can be disabling as it worsens the quality of life. Early detection of this congenital condition is crucial, and an invasive functional assessment of the ischemic burden should be considered to evaluate the need for medical or surgical therapy. This is an observational study, involving four Italian centres. Study Objectives are: To assess the risk of future cardiovascular complications in patients with MB referred for coronary angiography and the role of beta-blocker therapy; To describe the clinical and anatomical characteristics of patients presenting with MB; To determine the impact of cardiovascular medications on symptoms in patients with MB; To describe the anatomical and clinical features associated with the invasive evidence of ischemia in patients with MB; To assess the relation between invasively documented ischemia and clinical manifestations in patients with the MB. Inclusion Criteria: patients referred to undergo ICA (for both elective or urgent indications) for suspected coronary artery disease found to have an MB with or without other epicardial lesions amenable to revascularization; Age above 18 y.o.; Ability to provide Informed Consent. Exclusion Criteria are Patients with life expectancy below 12 months and Patients with severe valvular heart disease. The primary endpoint is the incidence of MACE defined as the composite of cardiac death, myocardial infarction, cardiac hospitalization, and target vessel revascularization. The secondary endpoint is evaluating the Rate of patients with SAQ < 70 and the Rate of patients with "high-risk features" on CT scan.
This study clarified the influence of myocardial bridge on coronary hemodynamics by clarifying FFR and d-FFR to guide clinical intervention and treatment.
Although the incidence of myocardial bridge (MB) has been defined in different conventional coronary angiography (CCA) studies,the frequency of MB in radial access coronary angiography (RACA) is unknown.The aim of this study was to determine the incidence of MB in patients undergoing RACA.
Coronary-related myocardial ischemia can result from obstructive epicardial stenosis or non-obstructive causes including coronary microcirculatory dysfunction and vasomotor disorders. This prospective study has been created in order to provide knowledge in the field of non-obstructive coronary artery disease.
The purpose of this study was to investigate the prevalence of physical and mental disorder in the population of patients with myocardial bridge and to describe the relationship between clinical features and the occurrence of somatic disorder.
The proposed clinical trial is relevant to public health because it is expected to expand the differential diagnosis and provide an evidence--based therapy for the large population of patients with angina in the absence of obstructive CAD who currently remain undiagnosed and untreated. It, therefore, upholds an important part of the mission of the The National Heart, Lung, and Blood Institute (NHLBI), which is to promote the treatment of heart disease and enhance the health of all individuals so that they can live longer and more fulfilling lives.
To examine the changes in left ventricular (LV) global longitudinal strain (GLS), using two-dimensional speckle tracking analysis, after left anterior descending (LAD) unroofing, in myocardial bridges (MBs) refractory to optimal medical therapy (OMT).
