BACKGROUND: Data on the clinical use of left atrial (LA) hemodynamic monitoring during MitraClip procedure are limited. This study evaluated the association between intraprocedural changes in LA pressure after MitraClip and improvement in exercise capacity as documented by 6-minute walk test (6MWT). METHODS AND RESULTS: Study population included 50 patients who underwent MitraClip at the Mayo Clinic (Rochester, MN), between June 2014 and July 2016 and completed both baseline and 30-day follow-up 6MWT...

BACKGROUND: Because of the rarity of this condition, information on pregnancy-associated spontaneous coronary artery dissection is limited. We reviewed a large number of contemporary pregnancy-associated spontaneous coronary artery dissection cases in an attempt to define the clinical characteristics and provide management recommendations. METHODS AND RESULTS: A literature search for cases of pregnancy-associated spontaneous coronary artery dissection reported between 2000 and 2015 included 120 cases; 75% presented with ST-segment-elevation myocardial infarction, and 80% had anterior myocardial infarction...

BACKGROUND: Patients with peripheral arterial disease (PAD) have high rates of adverse cardiovascular events after percutaneous coronary intervention and may additionally have heightened platelet reactivity. This study assessed the relationship between platelet reactivity and clinical outcomes after percutaneous coronary interventions among subjects with and without PAD. METHODS AND RESULTS: ADAPT-DES (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) was a prospective, multicenter registry of patients treated with coronary drug-eluting stents...

BACKGROUND: Embolic protection during carotid artery stenting reduces the rate of thromboembolic events. The Wirion Embolic Protection System is used to deploy an independent distal filter using any 0.014″ guidewire. WISE study (Wirion Study Europe) evaluated the safety and performance of Wirion Embolic Protection System in patients undergoing carotid artery stenting. METHODS AND RESULTS: A prospective, multicenter, nonrandomized, open-label, single-arm study of carotid artery stenting in high surgical risk patients was performed...

BACKGROUND: Pathological early Q waves (QW) are associated with adverse outcomes in patients with ST-segment-elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention (PCI) may therefore be less beneficial in patients with QW than in patients without QW. Myocardial salvage index and microvascular obstruction (MVO) are markers for reperfusion success. Thus, to clarify the benefit from primary PCI in STEMI patients with QW, we examined the association between baseline QW and myocardial salvage index and MVO in STEMI patients treated with primary PCI...

BACKGROUND: The therapeutic potential of renal denervation (RDN) for arrhythmias has not been fully explored. Detailed mechanistic evaluation is in order. The objective of the present study was to determine the antiarrhythmic potential of RDN in a postinfarct animal model and to determine whether any benefits relate to RDN-induced reduction of sympathetic effectors on the myocardium. METHODS AND RESULTS: Pigs implanted with single-chamber implantable cardioverter defibrillators to record ventricular arrhythmias (VAs) were subjected to percutaneous coronary occlusion to induce myocardial infarction...

For patients presenting with an acute ST-segment-elevation myocardial infarction, the most effective therapy for reducing myocardial infarct size and preserving left ventricular systolic function is primary percutaneous coronary intervention (PPCI). However, mortality and morbidity remain significant. This is partly attributed to the development of microvascular obstruction, which occurs in around 50% of ST-segment-elevation myocardial infarction patients post-PPCI, and it is associated with adverse left ventricular remodeling and worse clinical outcomes...

Pulmonary embolism (PE) is a serious and prevalent cause of vascular disease. Nevertheless, optimal treatment for many phenotypes of PE remains uncertain. Treating PE requires appropriate risk stratification as a first step. For the highest-risk PE, presenting as shock or arrest, emergent systemic thrombolysis or embolectomy is reasonable, while for low-risk PE, anticoagulation alone is often chosen. Normotensive patients with PE but with indicia of right heart dysfunction (by biomarkers or imaging) constitute an intermediate-risk group for whom there is controversy on therapeutic strategy...

BACKGROUND: The radial artery is increasingly adopted as the primary access site for cardiac catheterization because of patient preference, lower bleeding rates, cost effectiveness, and reduced risk of mortality in high-risk patient groups. Concerns have been expressed that operators/centers have become increasingly unfamiliar with transfemoral access. The aim of this study was to assess whether a change in access site practice toward transradial access nationally has led to worse outcomes in percutaneous coronary intervention procedures performed through the transfemoral access approach...

BACKGROUND: There are limited data on aspirin (ASA) desensitization for patients with coronary artery disease. The aim of the present study was to assess the safety and efficacy of a standard rapid desensitization protocol in patients with ASA sensitivity undergoing coronary angiography. METHODS AND RESULTS: This is a prospective, multicenter, observational study including 7 Italian centers including patients with a history of ASA sensitivity undergoing coronary angiography with intent to undergo percutaneous coronary intervention...

BACKGROUND: Sex differences in the outcomes after percutaneous coronary intervention with drug-eluting stents and in the response to clopidogrel therapy have been reported; however, the differential risk of high platelet reactivity (HPR) on clopidogrel in women versus men is unknown. METHODS AND RESULTS: We compared 8448 patients enrolled in the ADAPT-DES study (Assessment of Dual Antiplatelet Therapy With Drug-Eluting Stents) according to sex and the presence/absence of HPR on clopidogrel (defined as P2Y12 reactivity units >208)...
