Spontaneous coronary artery dissections (SCD) are more frequent in women and account for about 25% of all acute myocardial infarctions (AMI) before the age of 50. While the presence of cardiogenic shock due to AMI is infrequent, its evolution is still somewhat unclear and it has not been fully analyzed. Researchers conducted an analysis in...
Stent thrombosis (ST) is a serious complication of coronary PCI. However, its incidence across registries is low. It has been classified according to onset into acute (less than 24 hrs.), subacute (between 24 and 30 days), late (between 30 and 365 days) and very late (later than 365 days). The estimated incidence of ST is...
Acute kidney injury related to iodinated contrast significantly increases morbidity and mortality after angiography or angioplasty. According to registries, its prevalence can vary from 2% in low-risk population to up to 50% in high-risk subjects. Its risk factors include previous renal failure, diabetes, age, and the amount/type of contrast used. As a preventive measure, international...
The use of surgical bioprostheses has significantly increased, and while they last 15 years or more, in cases where they fail (usually due to stenosis), the decision-making process is challenging. Transcatheter aortic valve replacement (TAVR) is a good alternative for this situation, although information on the subject matter is still scarce. Currently, the only available...
Lecture by Dr. Hector García García – LM-PCI: IVUS and FFR/IFR? Dr. Hector García delivered an excellent presentation on whether we should use intravascular ultrasound (IVUS) or fractional flow reserve (FFR)/instantaneous wave-free ratio (iFR) in the left main coronary artery (LMCA) to consider severe obstruction, since there is significant interobserver variability with angiography. Although the...
Currently, the number of nonagenarian patients undergoing angioplasty (whether elective, urgent or emergency) has increased. This population is linked to more comorbidities and has barely been included in most randomized studies or registries. As such, we do not have robust evidence on this group. Researchers conducted an analysis of the J-PCI OUTCOME Registry, in which...
Left atrial enlargement with or without atrial fibrillation (AF), absence of valvular degeneration, and heart failure with preserved function have recently been identified as functional atrial mitral regurgitation (MR). This subtype of secondary MR currently appears to be underdiagnosed, and the need for treatment in the general population might be greater than predicted. The aim...
Edge-to-edge treatment of the mitral valve is currently a valid alternative to surgery in cases of mitral regurgitation. Different studies have taken residual mitral regurgitation as a parameter of success, but little research has been conducted on the residual gradient once the procedure has been completed. What has been published is that a mean gradient...
75% of patients with hypertrophic Cardiomyopathy present symptoms. An important group responds very well to pharmacological treatment with betablockers and calcium antagonists, and those who do not respond, or do not tolerate these drugs, receive, at present, surgery as elective treatment. There is also alcohol septal ablation as an alternative strategy, which different studies have...
Troponins have long had diagnostic value not only for infarction. Their ability to predict mortality is well established for all cardiac conditions. Moreover, it has been demonstrated in all critically ill patients, including patients with COVID-19, regardless of the triggering condition. While their significance in COVID cases is backed by the literature, there was not...
