Importance of Stent Optimization for Favourable Outcomes after Percutaneous Coronary Intervention for Chronic In-Stent Occlusions.

CONCLUSIONS: In-stent CTO-PCI with drug-eluting stent optimized by IVUS guidance offers acceptable long-term clinical results as that achieved in de novo CTOs. PMID: 31793885 [PubMed - as supplied by publisher]

We report the case of a 33-year-old woman with no history of coronary risk factors or chest pain who experienced intermittent chest pain at rest for several minutes from 2 PM. At 8 AM the next day, chest pain recurred and persisted for about 1 hour. She was transported to our hospital by ambulance, where electrocardiogram showed ST-elevation in the precordial leads, and blood tests showed elevation of cardiac markers. She was diagnosed with ST-elevation myocardial infarction. Because she was a young woman without any risk factors, coronary spastic angina was suspected. Coronary angiography without intracoronary nitrate adm...

Mintz, Nauman Khalid, Yuefeng Chen, Toby Rogers, Hayder Hashim, Itsik Ben-Dor, Hector M. Garcia-Garcia, Lowell F. Satler, Ron WaksmanBackgroundClinical data support the use of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) as being associated with improved outcomes. Nonetheless, global utilization of IVUS remains low. We hypothesize that in the revascularization of complex lesions, IVUS use is associated with improved outcomes.Met...

Microvascular obstruction is a common repercussion of percutaneous coronary intervention for distal microembolization, ischemia –reperfusion injury and inflammation, which increases post-myocardial infarction heart failure and mortality. Ultrasound-targeted microbubble cavitation (UTMC) may resolve microvascular obstruction while activating endothelial nitric oxide synthase (eNOS) and increasing endothelium-derived nitric oxide (NO) bioavailability. Nitrite, a cardioprotective agent, offers an additional source of NO and potential synergy with UTMC.

In this study, we aimed to establish the relationship between LRPs detected by NIRS-intravascular ultrasound imaging at unstented sites and subsequent coronary events from new culprit lesions.MethodsIn this prospective, cohort study (LRP), patients from 44 medical centres were enrolled in Italy, Latvia, Netherlands, Slovakia, UK, and the USA. Patients with suspected coronary artery disease who underwent cardiac catheterisation with possible ad hoc percutaneous coronary intervention were eligible to be enrolled. Enrolled patients underwent scanning of non-culprit segments using NIRS-intravascular ultrasound imaging. The stu...

Intravascular imaging (intravascular ultrasound, IVUS and optical coherence tomography, OCT) are recommended tools to optimize stent placement during percutaneous coronary intervention (PCI).1 The use of intravascular imaging is increasing among patients undergoing PCI for non-ST elevation myocardial infarction (NSTEMI).2 Data on temporal trends of intravascular imaging use in the setting of ST elevation myocardial infarction (STEMI) are unknown. We performed this study to analyze trends of intravascular imaging for PCI in setting of STEMI.

AbstractPurpose of ReviewThis review will provide recent pre-clinical and initial clinical trials exploring the efficacy of sonothrombolysis as an adjunct to current emergent therapies in acute coronary syndromes.Recent FindingsThe initial clinical trials examining the efficacy of short pulse duration diagnostic ultrasound (DUS) high mechanical index impulses in patients with ST segment elevation myocardial infarction (STEMI) have demonstrated that there is improved patency of the infarct vessel, and improved microvascular flow following percutaneous coronary intervention. Subsequent randomized prospective trials have conf...

Abstract BACKGROUND: Slow flow can be fatal in primary percutaneous coronary interventions for left main trunk (LMT)-acute myocardial infarction (AMI), however, risk factors for slow flow in LMT-AMI have not been well investigated. Intravascular ultrasound (IVUS) may help to stratify the high-risk lesion for slow flow in LMT-AMI. METHODS: A total of 51 LMT-AMI were included as the study population, and were divided into the slow-flow group (n=22) and the non-slow-flow group (n=29). Slow flow was defined as either transient or persistent Thrombolysis in Myocardial Infarction (TIMI) flow grade ≤2. RESUL...

AbstractPurpose of ReviewThe purpose of this article is to review the basic principles of near-infrared spectroscopy (NIRS) and its contemporary role in intracoronary imaging.Recent FindingsNIRS has been demonstrated to effectively detect culprit lesions in acute coronary syndromes (ACS) and to potentially identify vulnerable plaque. Lipid-rich plaques detected by NIRS are also associated with higher incidence of future adverse cardiac events. Plaques with high lipid content detected by NIRS have been shown to predict periprocedural myocardial infarction during percutaneous coronary intervention (PCI). The beneficial effec...
