Takayasu arteritis (TAK) is an uncommon granulomatous large-vessel vasculitis that affects the aorta and its primary branches. The most frequently types of observed vascular compromise are obstructive lesions, and aneurysmal vascular lesions or dissections. In 2021, the American College of Rheumatology recommended not to implement percutaneous intervention (PI) with these patients and only use immunosuppressive...

An Abbreviated Dual Antiplatelet Regimen Is Also Safe in Patients at High Risk for Bleeding Undergoing Complex Angioplasty The MASTER DAPT study analyzed the results of an abbreviated (mean 34 days) vs. conventional dual antiplatelet therapy (DAPT) in 4579 patients treated with angioplasty and a biodegradable polymer sirolimus-eluting stent....
Current guidelines recommend 12-month dual antiplatelet therapy (DAPT) after DES stenting for acute coronary syndrome (ACS) because of elevated MACE risk. The development of more modern stents, with thin and ultrathin struts, compared against prior versions, has resulted in more effective devices in terms of stent thrombosis and restenosis. Prolonged DAPT has been associated with...
There are many current randomized trials comparing percutaneous coronary intervention (PCI) with myocardial revascularization surgery (MRS) for the treatment of left main coronary artery disease (LMCAD). In the European Society of Cardiology guidelines, PCI is classified as Ia (LMCAD with low-complexity coronary disease) or IIa indication (intermediate complexity), whereas, according to the American Heart Association...
Changes in fractional flow reserve (FFR) values after percutaneous coronary intervention (PCI) are associated with improvement in angina symptoms. The pattern of baseline coronary artery disease influences the degree of variation in FFR after stent implantation. Focal coronary artery disease leads to high post-PCI FFR values, while the improvement is not as marked in diffuse...
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...
Non-adherence to medication in patients with acute coronary syndrome (ACS) remains to be solved; the use of polypills and a closer follow up have been tried out (follow up calls and motivation groups). Antiaggregation guidelines recommend dual antiplatelet therapy (DAPT) for at least one year after ACS. Adherence to drug treatment is comprised of multiple...
Aspiration thrombectomy (AT) in patients with high thrombotic burden could pathophysiologically reduce thrombus burden, decrease distal embolization, reduce no-reflow phenomenon, and improve microvascular perfusion. However, its usefulness has not been shown in the large, randomized trials (TASTE and TOTAL) that compared routine use of AT in primary angioplasty in patients with ST-segment elevation acute coronary...
Current use of transcatheter aortic valve replacement (TAVR) has increased in intermediate-risk patients and has even been used in low-risk patients. Vascular access-related complications and bleeding are still frequent after transfemoral TAVR, being associated with poor short- and long-term outcomes. Using percutaneous closure devices has allowed operators to close the access site without surgery. The...
