Spontaneous coronary artery dissection (SCAD) is a non-traumatic nor iatrogenic event that causes a separation of the coronary artery tissue due to an intimal tear or a mural spontaneous hemorrhage. This event is most frequent in young females and usually causes an acute myocardial infarction that could be major. It accounts for 1% to 4%...
Transcatheter aortic valve replacement (TAVR) by transfemoral access has shown great benefit for different risk groups, but its long-term durability is still uncertain. Available evidence comes from small analysis and a single randomized trial with 280 patients and an 8 year follow-up: the NOTION Trial, where TAVR showed less valvular degeneration than aortic valve replacement (AVR) surgery....
Since its inception, transcatheter aortic valve replacement (TAVR) has improved greatly. However, there still are five big challenges to be solved: paravalvular leak, conduction disturbances, debilitating stroke, impaired kidney function, and major vascular complications and bleeding. Most cases of stroke are periprocedural and ischemic. So far, they have not been well analyzed in terms of...
The inclusion of fractional flow reserve (FFR) has changed how coronary interventions are treated. Current guidelines endorse its use in intermediate lesions with no evidence of ischemia in non-invasive studies in patients with multivessel disease. The original RIPCORD (Routine Pressure Wire Assessment Influence Management Strategy at Coronary Angiography for Diagnosis of Chest Pain) study proposed...
Heart disease is the most frequent cause of heart failure and, in some observational studies, transluminal coronary angioplasty (TCA) could help improve ventricular function. The only major randomized study to compare myocardial revascularization surgery (MRS) vs. medical treatment in patients with ventricular function impairment was the STICH study, which showed no difference at 5 years,...
Percutaneous coronary intervention of chronic total occlusions (CTO) is currently indicated for symptom improvement, as studies have inadequate randomization of data which hinders the assessment of hard outcomes. However, patient inclusion in randomized controlled trials has been challenging, especially for highly symptomatic and higher risk patients. This causes a selection bias in randomized studies on...
Intervention of chronic total occlusions (CTO) through angioplasty (PCI) can cause complications, even in highly experienced centers. Plenty has been written on the probability of success for the treatment of CTOs using scores such as CL-SCORE, J-CTO, ORA, E-CTO, CASTLE-CTO, etc. (some of which are usually used when preparing these cases). However, besides estimating success...
About 4% of the population suffers from tricuspid regurgitation (TR). This disease is associated with hard-to-manage heart failure (HF)—often requiring hospitalization—and with mortality. Surgery in this valve is not simple and has high morbidity and mortality rates due to its comorbidities. Currently, a percutaneous strategy for its resolution is under development, but we still do...
Percutaneous treatment of coronary lesions affecting bifurcations has increased in recent decades. Coronary angioplasty (percutaneous coronary intervention, PCI) in these cases is associated with an increased rate of adverse events in patients with multivessel disease and left main coronary artery lesions. The SYNTAX score, which is a predictor of total mortality, is used to evaluate...
Cardiovascular disease is one of the main causes of morbidity and mortality in patients with advanced chronic kidney disease (CKD), and vice-versa. Both diseases share risk factors, including, but not limited to, diabetes, high blood pressure, smoking, dyslipidemia, and old age. As kidney disease develops, its severity grade has been linked to more thrombotic events...
