PCI Registry Basel

This registry aims to learn more about the best ways to treat coronary artery disease. Information from routine medical care will be collected to compare different treatment approaches, including drug-eluting stents, drug-coated balloons (DCB), and bioresorbable scaffolds (BRS), which gradually dissolve over time. The registry will include people with coronary artery disease who receive an intervention (percutaneous coronary intervention), including those undergoing more complex procedures. By studying treatment outcomes over time, the Registry aims to better understand which therapies work best for different groups of patients and to improve future care for people with coronary artery disease.

A MAajor RAdiation-based PCI Study in STEMI and NSTEMI

In France and Italy, approximately 240,000 percutaneous coronary angioplasties (PCI) are performed annually, with an increasing number of complex procedures, including those involving the left coronary common trunk, a bifurcation, chronic occlusion, or requiring Rotablator Rotary Atherectomy (ARota). The medical literature lacks sufficient data regarding several key aspects of complex angioplasty. These include the epidemiological characteristics of patients undergoing such procedures, the impact of irradiation delivered and the quantity of iodine injected on these lengthy procedures, their procedural complication rate, and in-hospital mortality.

Trial Comparison of Accuseal and Bovine Pericardial Patch During Endarterectomy

Carotid Endarterectomy (CEA), surgical removal of the blockage in the neck artery, is the accepted management of choice for significant blockage of the carotid artery. Previous studies showed improved perioperative outcomes and prevention of recurrent blockage by the use of the patch to close the surgical incision in the artery. The ideal patch reduces bleeding and prevents recurrent blockage.This is looking at long-term results toward improvement with the use Accuseal patch than Bovine Patch.

Hybrid Sirolimus-eluting Versus Everolimus-eluting Stents for Total Coronary Occlusions

Percutaneous recanalization of total coronary occlusions (TCO) was historically hampered by high rates of restenosis and reocclusion. In the PRISON II and III trial we showed landmark reduction in restenosis with sirolimus-eluting stents (Cypher, Cordis Corporation) compared to conventional bare metal stents in TCO. In the PRISON III trial, we observed similar favourable results with second-generation zotarolimus-eluting stent (Resolute, Medtronic Inc.). Another drugs-eluting stent mounted with everolimus (Xience Prime, Abbott) also demonstrated favourable results in TCO. Recently, drug-eluting stents (DES) with bioresorbable polymer coatings were developed, to address safety concerns regarding the observation of very late stent thrombosis, due to hypersensitivity reactions, and chronic inflammation, on the durable polymer coating of DES. However, none of these DES with bioresorbable polymers were evaluated in patients with TCO. The PRISON IV trial is a prospective, randomized, single-blinded, multi-center trial, designed to evaluate the safety, efficacy, and angiographic outcome of hybrid sirolimus-eluting stents with bioresorbable polymers (ORSIRO, Biotronik Inc.) compared to everolimus-eluting stents with durable polymers (Xience Prime, Abbott) in patients with successfully recanalized TCOs.

QFR-Guided Virtual Stenting for Preprocedural Physiological Optimization of Percutaneous Coronary Intervention: A Randomized Controlled Trial

Coronary angiography-guided percutaneous coronary intervention (PCI) remains the standard treatment strategy for patients with coronary artery disease; however, suboptimal post-PCI physiological outcomes remain common and are associated with adverse cardiovascular prognosis. Quantitative Flow Ratio (QFR)-based virtual stenting technology enables simulation of post-intervention coronary physiology before PCI and may facilitate individualized optimization of stent implantation strategies. This multicenter, prospective, randomized controlled trial aims to evaluate whether preprocedural physiological optimization of PCI using coronary imaging-physiology fusion-based virtual stenting technology improves clinical outcomes compared with conventional angiography-guided PCI. Eligible patients undergoing PCI for coronary artery disease will be randomized in a 1:1 ratio to either virtual stenting-guided PCI optimization or standard angiography-guided PCI. The primary endpoint is major adverse cardiovascular events (MACE), defined as a composite of all-cause death, nonfatal myocardial infarction, and ischemia-driven repeat revascularization within 1 year after PCI. Secondary endpoints include post-PCI physiological optimization, cardiovascular death or nonfatal myocardial infarction, repeat revascularization, quality of life, procedural safety, and health economic outcomes.

Retrospective Algorithm Validation of IVUS-FFR in Patients

This is a retrospective, single-center study to develop and validate an updated algorithm for computing fractional flow reserve from intravascular ultrasound images (IvusFFR v2.0). The study will use existing intravascular ultrasound (IVUS) images and corresponding invasive fractional flow reserve (FFR) measurements obtained from approximately 100 patients who underwent clinically indicated coronary angiography, IVUS, and FFR assessment at Fuwai Hospital. All data will be anonymized prior to analysis. The primary objective is to assess the diagnostic accuracy of IvusFFR v2.0 in identifying hemodynamically significant coronary stenosis, using wire-based FFR ≤0.80 as the reference standard. This study involves no prospective intervention or additional patient contact.

Century Trial, a Randomized Lifestyle Modification Study for Management of Stable Coronary Artery Disease

The Century Trial is a single center Phase III randomized study sponsored by the Albert Weatherhead III Foundation and conducted by Dr. K. Lance Gould. The study hypothesis is that a combined image-treatment regimen of PET + comprehensive program of lifestyle modification and lipid lowering drugs to target lipid level will result in an improved cardiovascular risk score when compared to current standard optimal medical therapy, potentially resulting in a lower rate of death, non-fatal myocardial infarction (MI) and revascularization procedures during long term follow-up when compared with current standard of care. If our hypothesis is correct, we will not only improve our ability to prevent and treat CAD but we will also illustrate that, even with the expenses of behavioral interventions and imaging techniques, we can be very cost effective. This information may help patients at risk or with known CAD to obtain insurance coverage to prevent the disease as well as providing a more effective way of treating it.

Staged Complete Revascularization for Coronary Artery Disease vs Medical Management Alone in Patients With AS Undergoing Transcatheter Aortic Valve Replacement

Patients undergoing transcatheter aortic valve replacement (TAVR) often have concomitant coronary artery disease (CAD) which may adversely affect prognosis. There is uncertainty about the benefits and the optimal timing of revascularization for such patients. There is currently clinical equipoise regarding the management of concomitant CAD in patients undergoing TAVR. Some centers perform routine revascularization with percutaneous coronary intervention (PCI) (either before or after TAVR), while others follow an alternative strategy of medical management. The potential benefits and optimal timing of PCI in these patients are unknown. As TAVR expands to lower risk patients, and potentially becomes the preferred therapy for the majority of patients with severe aortic stenosis, the optimal management of concomitant coronary artery disease will be of increasing importance. The COMPLETE TAVR study will determine whether, on a background of guideline-directed medical therapy, a strategy of complete revascularization involving staged PCI using drug eluting stents to treat all suitable coronary artery lesions is superior to a strategy of medical therapy alone in reducing the composite outcome of Cardiovascular Death, new Myocardial Infarction, Ischemia-driven Revascularization or Hospitalization for Unstable Angina or Heart Failure. The study will be a randomized, multicenter, open-label trial with blinded adjudication of outcomes. Patients will be screened and consented for elective transfemoral TAVR and randomized within 96 hours of successful balloon expandable TAVR. Complete Revascularization: Staged PCI using third generation drug eluting stents to treat all suitable coronary artery lesions in vessels that are at least 2.5 mm in diameter and that are amenable to treatment with PCI and have a ≥70% visual angiographic diameter stenosis. Staged PCI can occur any time from 1 to 45 days post successful transfemoral TAVR. Vs. Medical Therapy Alone: No further revascularization of coronary artery lesions. All patients, regardless of randomized treatment allocation, will receive guideline-directed medical therapy consisting of risk factor modification and use of evidence-based therapies. The COMPLETE TAVR study will help address the current lack of evidence in this area. It will likely impact both the global delivery of health care and the management and clinical outcomes of all patients undergoing TAVR with concomitant CAD.

Wearable Devices Assist in the Detection, Screening, and Management of Major Diseases in Middle-aged and Elderly Populations

The goal of this randomized controlled trial is to evaluate the effectiveness of wearable devices (Huawei smartwatches) in aiding the detection, and screening of major diseases (e.g., coronary artery disease, hypertension) in middle-aged and elderly populations aged 40-69 years with cardiovascular risk factors (e.g., smoking, diabetes, hypertension, dyslipidemia). The main questions it aims to answer are: Does AI-assisted diagnosis using wearable device data improve the detection rate of coronary artery stenosis (CAD-RADS ≥3) compared to standard physician assessment without AI assistance? Does the intervention reduce the incidence of coronary artery disease-related events (e.g., angina, myocardial infarction) within one year? Researchers will compare the intervention group (AI model-assisted diagnosis based on Huawei smartwatch data) with the control group (standard assessment) to determine if the AI-aided smartwatch approach enhances diagnostic accuracy and clinical outcomes. Participants will: (Intervention group)Wear a Huawei smartwatch for 24 hours to collect physiological data (e.g., PPG signals, heart rate, motion). Undergo baseline assessments, including medical history review, physical exams, and laboratory tests. Receive a preliminary diagnosis from a general practitioner. Complete a follow-up evaluation after one year to track cardiovascular events and other disease outcomes. Undergo coronary CTA if suspected of coronary stenosis.

Transit Time Flow Measurement in Coronary Surgery

Transit-time flowmetry (TTFM) allows grafts quality control during coronary artery bypass surgery by measuring the flow volume through them. To date, many studies have deeply studied the predictive role on the graft outcomes of the various flowmetry-derived parameters. One of the least investigated aspects, however, is the mutual influence that two newly realized grafts can have. This possibility would be related to the presence of a more or less developed collateral circulation between the bypassed territories. The purpose of this study is to assess whether a graft for a territory different than that provided by the left anterior descending artery (LAD) may affect the functionality (measured through flowmetry) of the left internal mammary artery - LAD graft.
