A lesion ≥50% in the left main coronary artery (LMCA) is considered severe, according to various scientific societies, regardless of the presence of symptoms or ischemia, due to the extent of myocardium at risk. In such cases, revascularization is indicated. In many patients, lesions in this section of the coronary artery have severe calcification, which<a href="https://solaci.org/en/2024/03/13/lithotripsy-in-the-left-main-coronary-artery/" title="Read more" >...</a>
Chronic total occlusions (CTO) occur in up to 20% of patients undergoing diagnostic angiographic studies. Over the past two decades, the optimization of recanalization techniques, the development of new specialized devices, and improvement in operator skill have contributed to an increased procedural success rate, reaching 90%. However, specific complications such as collateral perforation and access<a href="https://solaci.org/en/2024/03/08/ercto-registry-current-results-for-percutaneous-treatment-of-chronic-total-occlusions/" title="Read more" >...</a>
The edge-to-edge approach with MitraClip has been established as a valid strategy for patients who experience severe symptomatic mitral regurgitation (MI) with high risk for surgery, currently with a IIa indication. MI complicated by cardiogenic shock, which results in a high risk for conventional valve surgery, is a particularly complex scenario. In such a case,<a href="https://solaci.org/en/2024/02/26/edge-to-edge-repair-in-cardiogenic-shock/" title="Read more" >...</a>
Coronary artery disease, both obstructive and non-obstructive, often coexists with significant aortic stenosis. Therapeutic decision-making in this scenario remains controversial, not only regarding the need for treatment, but also about when it should be addressed, considering its pros and cons. Various analyses have yielded contradictory data, as most lesions are chronic and stable. Currently, the<a href="https://solaci.org/en/2024/02/07/should-we-treat-obstructive-coronary-artery-disease-in-tavi/" title="Read more" >...</a>
Transcatheter aortic valve replacement (TAVR) has widely demonstrated its significant benefits, both in high-risk and inoperable patients, as well as in those with intermediate and low risk. While paravalvular regurgitation has been a challenge, its management has improved with operator experience and a deeper understanding of CT angiographies. However, in cases of regurgitation, elevated gradient,<a href="https://solaci.org/en/2024/02/01/does-post-dilation-in-tavr-affect-its-long-term-outcomes/" title="Read more" >...</a>
The effects of diabetes on patients with coronary artery disease are well-known, and their outcomes after angioplasty are less favorable, with a higher rate of restenosis, recurrent acute myocardial infarction, and stent thrombosis. Despite advances in drug-eluting stents and procedural techniques, the treatment of coronary bifurcation lesions in diabetic patients shows less positive clinical outcomes<a href="https://solaci.org/en/2024/01/18/long-term-results-of-coronary-bifurcation-lesion-treatment-in-diabetic-patients/" title="Read more" >...</a>
Aortic stenosis (AS) is a progressive disease associated with morbidity and mortality, especially in severe cases. However, recent studies have revealed that moderate stenosis can also have unfavorable consequences in the course of the disease. One of the challenges lies in that determining its severity is sometimes difficult due to discrepancies between valve area, gradient,<a href="https://solaci.org/en/2023/12/04/is-as-only-important-when-severe/" title="Read more" >...</a>
While the benefits of dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor are recognized, its primary complication is the occurrence of bleeding events, which negatively impact patient morbidity and mortality. Additionally, about 10% of patients undergoing percutaneous coronary intervention (PCI) are on oral anticoagulant therapy, which significantly increases the risk of bleeding when<a href="https://solaci.org/en/2023/11/23/optimal-duration-of-dapt-with-oral-anticoagulation-after-pci-1-month-vs-3-months/" title="Read more" >...</a>
Approximately 20% of all percutaneous coronary interventions (PCI) are performed on bifurcation lesions, which continue to pose a challenge in terms of strategy: how many stents to use, what is the most suitable strategy, and when to transition from a single stent to two during the procedure. Additionally, the use of two stents in these<a href="https://solaci.org/en/2023/10/06/treatment-and-gender-based-outcomes-for-coronary-bifurcation-stent-placement-report-from-the-e-ultimaster-registry/" title="Read more" >...</a>
Transcatheter aortic valve replacement (TAVR) has shown remarkable benefits and continues to advance towards lower-risk patients and younger ages. However, one of its limitations lies in the demand for a permanent pacemaker (PPM), which during TAVR early stages with self-expanding valves reached 30%. Uncertainty persists regarding the evolution of patients undergoing PPM implantation after TAVR,<a href="https://solaci.org/en/2023/08/17/predictors-and-evolution-of-permanent-pacemaker-after-tavr-with-self-expanding-valves/" title="Read more" >...</a>
