Intramural hematoma (IMH) is considered a subtype of acute aortic syndrome (AAS), and some authors describe it as a developmental stage that might cause high morbimortality events such as dissection, aneurysm, or aortic rupture. One of the CT findings associated with IMH is focal contrast enhancement (FCE) within the intramural hematoma, with a reported incidence...
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...
Tricuspid regurgitation has become increasingly common, and current pharmacological treatment options are limited. In turn, surgery, which is a complex alternative, carries considerable rates of complications and mortality. In response to this issue, various percutaneous systems are being developed, such as edge-to-edge treatment, percutaneous annuloplasty, and caval valve implantation (CAVI), among others. In the analysis...
Severe aortic stenosis due to a bicuspid aortic valve (BAV) is uncommon, especially in individuals under 65 years of age. While there are usually no significant differences according to the type of valve when it comes to surgery, with transcatheter aortic valve replacement (TAVR) some may arise. TAVR has seen significant advancements in the treatment...
Mitral regurgitation (MR) is a frequent valvulopathy and when the optimal medical treatment at maximum tolerated doses is not enough, surgery is the first course of action. And even though edge-to-edge repair with clips has seen substantial improvement, it is currently reserved for those at high risk of surgery. However, there is an increasing number...
While the rate of stroke has decreased since the early days of transcatheter aortic valve replacement (TAVR), it remains non-negligible, reaching up to 1%-3% at 30 days. As TAVR progressively expands to low-risk populations and younger patients, identifying risk factors for patient selection and management in stroke prevention becomes crucial. While researchers have identified predictors...
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,...
In patients with peripheral vascular disease (PVD), the presence of diabetes has been significantly associated with increased failure of critical lower limb ischemia (CLI) treatment, and higher incidence of amputation. This relationship has been attributed mainly to comorbidities and patient characteristics, concomitant peripheral neuropathy and marked microvascular alteration. Also, a high proportion of these patients...
Severely calcified lesions currently pose a significant challenge, as they require adequate preparation through non-compliant balloons or cutting balloons to achieve effective stent expansion. Another option is the use of orbital or rotational atherectomy (RA), but this carries the risk of complications such as slow/no reflow, perforations, dissections, peri-procedural infarction, or guidewire rupture. Despite the...
The incidence of stroke after TAVR ranges between 2 and 5%, depending on the series, which has been associated with higher morbimortality, affecting patient quality of life and their psycho-social environment. Many cerebral embolic protection systems have been developed in response, and even though they have been shown beneficial in many studies, their role in...
