For many years, percutaneous transluminal coronary angioplasty (PCTA) has expanded significantly worldwide. However, despite the demonstrated advantages of intravascular ultrasound (IVUS) in terms of minimal luminal area, reduced cardiovascular events, and restenosis, its use is not very common due to various reasons. On the other hand, optical coherence tomography (OCT) offers even higher resolution than...
TAVI (Transcatheter Aortic Valve Implantation) has proven to be beneficial and is currently performed in increasingly younger and lower-risk patients. However, as with surgical bioprostheses, structural deterioration, whether due to stenosis or regurgitation, is one of the challenges we must address. While currently uncommon, this is an issue we will probably see more and more...
Among patients undergoing percutaneous coronary intervention (PCI), there is a need for risk stratification for successful planning and post procedural management. Risk stratification is paramount for effective decision making. For a long time, the SYNTAX score has been the preferred tool for complex PCI patient risk assessment. However, it has important limitations, such as inter-observer...
Calcified coronary plaque (CCP) is a challenge for interventional cardiology. Stent underexpansion (SU) commonly associated with CCP could predispose to stent thrombosis or restenosis. Currently, SU in severe CCP can be treated by rotational atherectomy, orbital atherectomy, balloon cutting/scoring, non-compliant high-pressure balloons, or intravascular lithotripsy (IVL). The aim of this meta-analysis was to determine the...
3 Year Clinical Outcome Analysis and Failure Predictors in the Use of Intracoronary Brachytherapy for Drug-Eluting Stent Restenosis In-stent restenosis (ISR) has been one of the greatest obstacles standing in the way of long term patency in percutaneous coronary interventions. However, the use of drug eluting stents (DES) and their development has helped reduce ISR...
Left main coronary artery percutaneous coronary intervention (LMCA PCI) is a treatment option that is increasingly used in our setting. One of the reasons for choosing this therapeutic strategy is the improvements in devices and techniques. However, the long-term results of LMCA PCI are not well established. The aim of this retrospective study was to...
Stent sub-expansion in coronary territory has been identified as one of the major predictors of stent failure at followup, which is why improving stent expansion will improve clinical and imaging outcomes. In percutaneous coronary interventions (PCI) of severely calcified lesions, calcified lesions present a major challenge since they impede stent delivery, causing stent under-expansion or...
Severely calcified coronary lesions are found in 25% of patients undergoing PCI, and their presence has a negative impact in long term outcomes. These lesions difficult stent expansion and increase device failure rate, even when using the latest generation of drug eluting stents (DES). This is why there is an interest in lesion preparation strategies...
Vascular calcification is a predictor of difficult stent positioning and expansion, which increases the chance of device failure (even with last generation stents). Calcium modifying strategies are being developed to reduce these difficulties. Two recent randomized studies compare different calcium preparation devices. The PREPARE-CALC compares rotational atherectomy (RA) against plaque modifying balloons (PMB = cutting...
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...
