Coronary sinus reduction (CSR) is a relevant area of study for the treatment of refractory angina, with hopes of improving myocardial perfusion. However, to date, there are no conclusive data. The ORBITA-COSMIC study is a randomized, double-blind, placebo-controlled trial conducted at six centers in the UK. Researchers recruited patients with angina and chronic ischemia who…
ACC 2024 | IVUS-DCB
Drug-coated balloons (DCB) have proven to be effective in the treatment of femoropopliteal pathology, although they entail complications such as recoil, residual stenosis, and dissection. Their outcomes could be improved through proper and enhanced vessel preparation, both before and after the procedure. Intravascular ultrasound (IVUS) offers the advantage of characterizing plaque and assessing vessel diameter.…
ACC 2024 | REDUCE AMI: Beta-Blockers after Myocardial Infarction and Preserved Ejection Fraction
Most clinical trials have shown benefits of beta blockers after acute myocardial infraction, including patients with extensive AMI, and these were carried out in the era before AMI was diagnosed with biomarkers and prior to treatment with coronary angioplasty, use of antithrombotic agents and high intensity statins, and angiotensin-aldosterone system inhibitors. The aim of this…
ACC 2024 | SMART Trial: Self-Expanding or Balloon-Expandable TAVR in Patients with Small Aortic Annulus
Patients with severe aortic stenosis and a small aortic annulus face an increased risk of deteriorated valvular hemodynamic performance and adverse cardiovascular clinical outcomes after undergoing transcatheter aortic valve replacement (TAVR). This study, a prospective multicenter randomized trial, aimed to compare the efficacy and safety of two types of valves: the supra-annular self-expanding EVOLUT (SEV)…
ACC 2024 | DEDICATE Trial: Transcatheter or Surgical Treatment of Aortic Valve Stenosis
In recent years, TAVR has been increasingly used; however, when it comes to younger, lower risk patients, its use is still challenged. In this context, there is limited information and we lack randomized studies on “real world” cohorts. The DEDICATE randomized 1.414 patients over 65 with severe symptomatic aortic stenosis. 701 of these patients received…
ACC 2024 | PREVENT Study
The use of intravascular imaging to identify vulnerable plaque (VP) has proven to be very useful, as such plaque is associated with an increase in major adverse cardiac events. Optimal medical treatment is currently considered the standard strategy to stabilize VP. However, the safety and effectiveness of preventive treatment with percutaneous coronary intervention (PCI) in…
ACC 2024 | DanGer-Shock Trial
Cardiogenic shock will develop in approximately 10% of patients with ST elevated acute MI (STEMI), and unfortunately, only half of these patients will survive. Researchers have been looking into the Impella system to manage this severe complication. It consists of an aortic transvalvular pump designed to deliver blood from the left ventricle into the systemic…
ACC 2024 | ULTIMATE-DAPT Trial
The international guidelines recommend the use of dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor during 12 months in patients receiving percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS), to prevent events such as MI and stent thrombosis. This was a multicenter, placebo controlled, double blind study to determine whether ticagrelor alone,…
ACC 2024 | RELIEVE-HF
Heart failure is characterized by increased left atrial filling pressure and venous congestion which intensify with exercise and volume burden, and makes conventional medical management hard. In this context, interatrial shunting might offer a self-regulating mechanism, as shown by the Ventura IAS study. The aim of this study was to assess the safety and efficacy…
