Filter by:In spite of technological advances, PCI of complex calcified coronary lesions remain a challenge. Observational studies demonstrate that moderate or severe calcifications in lesions to treat are associated with an increase in mortality, in myocardial infarctions, in stent thrombosis, and in complementary revascularizations. Rotational atherectomy is now part of therapeutic armamentarium of interventional cardiologists for the treatment of some complex calcified coronary lesions. Last recommendations of the European Society of Cardiology about revascularizations indicate that rotational atherectomy should be used for "the preparation of calcified or massive fibrotic lesions that cannot be crossed by a balloon or for an optimal dilatation before stenting". However, this technique is not frequently used and limited to high-volume PCI centers. Even though rotational atherectomy demonstrated an improvement in immediate success of complex lesions, the longterm reduction of cardiovascular events after active stenting has not been proved. In observational studies, the results are not consistent because of many selection biases that influence the choice of an angioplasty with rotational atherectomy device (calcifications, severity of the disease). Furthermore, this technique needs operators with a certain amount of experience. The fundamentals of an optimal use of rotational atherectomy remain to be defined (duration and speed of burr, anti-platelet treatments...).
The investigators' study aims is to evaluate the safety and efficacy of percutaneous transluminal angioplasty (PTA) with paclitaxel-coated balloon (PCB) at venous anastomotic stenosis of arteriovenous graft (AVG) in patients with hemodialysis
This is a First In Man study with the aim to know the safety and effectiveness of a novel bare metal stent (INC-1) in the treatment of de novo coronary lesions in patients with stable coronary angina and unique coronary lessions.
Hospital readmission rate following percutaneous coronary interventions (PCI) or coronary angiographies (CAG) is a main indicator of quality of care and addresses economic issues. The aim of this study is to quantify the frequency and analyse the types of rehospitalizations and repeat revascularizations during one year after a PCI or a CAG. This information is needed to organize the health care pathway and to identify preventable rehospitalizations.
The study evaluates whether routine use of ultrasound for sheath insertion during radial or femoral angiography or angioplasty has any impact on: number of punctures, patient discomfort, procedural length, successfull procedure or ideal vessel puncture.
To evaluate Safety and Efficacy of Axiostat® hemostatic dressing in terms of time to achieve hemostasis, post application complication and comfort levels of patients.
Rigorous clinical practice assessment is a key factor to improve patient's care and prognosis in interventional cardiology (IC). A multicentric IC observational study (CRAC), fully integrated to usual coronary activity report software, started in Centre Val de Loire (CVL) region in 2014. CRAC observatory was conduced on five IC CathLab of CVL region. Quality of collected data is regularly evaluated and allowed building an exhaustive, and reliable database. This solution could easily be developed in other French regions.
The primary objective of this double-blind study is to compare the frequency of primary patency at 6 months in patients with stenosis of arteriovenous fistula (AVF) treated either by conventional angioplasty + angioplasty with balloon impregnated with paclitaxel or by conventional angioplasty + angioplasty with placebo balloon (balloon not impregnated with paclitaxel). The other objectives of the study are: 1. To compare the frequency of primary patency at 3 months and 12 months. 2. To compare the rate of restenosis > 50% at the site of angioplasty at 3, 6 and 12 months. 3. To compare, at 3, 6 and 12 months, the proportion of patients with arteriovenous fistula deteriorating back to preoperative flow rate (within 20% of preoperative flow rate). 4. To compare, at 3, 6 and 12 months, the proportion of AVF with a flow rate < 500 ml / min. 5. To compare, at 3, 6 and 12 months, the cumulative rate of thrombosis. 6. To compare, at 3, 6 and 12 months, the medical costs related to direct medical care, initial treatments, monitoring, diagnosis and treatments of complications.
The guideline-recommended standard of care for patients who have experienced a heart attack, heart failure, or other coronary event or procedure is exercise-based cardiac rehabilitation (CR). Despite proven benefits, traditional CR is severely underutilized. Moreover, what is typically lacking from traditional CR programs is effective psychosocial risk management. This represents a critical gap in care given the well-documented psychosocial needs of this patient population.The objective of this feasibility study is to conduct a pilot randomized controlled trial (RCT) of Mindfulness-Based Stress Reduction (MBSR) versus usual care in CR-eligible cardiac patients. Randomization will be stratified within two strata based on participation in CR (yes/no) among CR-eligible patients. The primary goals of this pilot study are to: 1) obtain estimates of treatment effects and variability; 2) evaluate recruitment and retention strategies; and 3) examine the safety of the MBSR protocol in CR-eligible patients.
The aim of the study is to use optical coherence tomography (OCT) to investigate the efficacy of Paclitaxel-eluting PTCA-balloon dilation (SeQuent Please) in SB and drug eluting stent (EXCEL stent) deployment in the main branch (reference diameter: ≥ 2.5 mm and ≤ 4.0 mm, reference diameter of side branch: ≥ 2.0 mm and ≤ 3.5 mm, length of stenoses in either branch ≤ 30 mm) in the treatment of significant (>70%) de-novo-bifurcation stenoses of any Medina classification type in the native coronary artery as reflected by procedural success and to evaluate the preservation of vessel patency.
