IntroductionIntracranial atherosclerotic disease (ICAD) is associated with up to 32% of posterior circulation strokes.1 Rescue treatment with stenting, balloon angioplasty, and/or intraarterial thrombolysis or antiplatelets are often required to treat the underlying stenosis.
In a recent study published in Circulation , examined how diabetes influences outcomes in left main coronary revascularization procedures, specifically PCI versus CABG, is crucial for tailored treatment strategies. Circulation. Original article: Gaba P et al. 2024;149:00–00.
Circulation: Cardiovascular Interventions, Volume 17, Issue 1 , Page e013006, January 1, 2024. BACKGROUND:We previously reported the use of minimal stent area to predict angiographic in-stent restenosis after drug-eluting stent implantation for unprotected left main (LM) disease. P=0.15), 8.3 P=0.02), and 5.7 P=0.15), 8.3
Background:In stroke patients undergoing EVT, angioplasty and stenting (A&S) has been described as a bailout technique when thrombectomy fails or intracranial stenosis is suspected. The stent-retriever was re-sheathed into the microcatheter before retrieval. Further prospective data is warranted.
Circulation, Volume 150, Issue Suppl_1 , Page A4145821-A4145821, November 12, 2024. In this hyperacute emergent clinical situation, covered stents have been considered as a primary measure to prevent further serious arterial events. A fabric-based covered graft stents yield poor clinical outcomes. x 24 mm). at 2weeks, 26.1
Over time, robust anastomoses may develop between the patent ipsilateral external carotid artery and the anterior circulation distal to the site of occlusion. Stenosis of the external carotid artery in such patients can be a source of atheroembolism or hypoperfusion. The patient was treated with aspirin and ticagrelor for 3 months.
PR was calculated as the ratio of proximal to distal pressure at the stenosis site, indicating post-stenosis blood flow. Arterial stenosis severity was categorized using the WASIDMethod:50%-69% for moderate and 70%-99% for severe. frequency was significantly higher in severe compared to moderate stenosis (P=0.01).
Circulation, Volume 151, Issue 12 , Page 835-846, March 25, 2025. BACKGROUND:In patients with post-thrombotic syndrome, stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes.
Circulation, Ahead of Print. BACKGROUND:Diabetes may be associated with differential outcomes in patients undergoing left main coronary revascularization with percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).
Circulation, Volume 150, Issue Suppl_1 , Page A4135852-A4135852, November 12, 2024. Background:Vertebrobasilar artery stenosis (VBAS) can cause posterior circulation strokes (PCS). Optimal management is controversial, with options including medical therapy (MT), endovascular stenting (ES), and surgical revascularization (SR).
Circulation: Cardiovascular Interventions, Volume 18, Issue 1 , Page e014665, January 1, 2025. BACKGROUND:Bioresorbable scaffolds (BRS) were developed to overcome limitations related to late stent failures of drug-eluting stents, but lumen reductions over time after implantation of BRS have been reported.
ml/h, P = 0.04), a higher likelihood of parent artery stenosis (65% vs. 20.8%, P < 0.001), and increased need for angioplasty or stenting (50% vs. 17%, P < 0.001). Follow-up lesion volumes and functional outcomes were similar; however, the mismatch group showed a slower infarct growth rate (3.8 ml/h vs. 7.5
We also compared the safety of acute carotid stenting (CAS) in TLs with low ASPECTS.Methods:This prospective multicenter study from 16 centers included patients with anterior circulation TL from 2015-2020. in patients with stenting (18/44) versus no-stenting (25/44).Conclusion:This 3.05; p=0.32), PH2 (OR: 1.14, CI: 0.26-5.02;
Circulation, Volume 150, Issue Suppl_1 , Page A4142716-A4142716, November 12, 2024. A coronary angiogram revealed non-obstructive left coronary arteries and a dominant right coronary artery (RCA) with heavily calcified stenosis at the bifurcation of the right posterolateral (RPL) and right posterior descending (RPD) branches.
However, CTA head and neck 4 days later demonstrated 90 percent stenosis of the mid left V2 at the C3‐4 level and a 75‐90 percent stenosis of the left mid V2 segment at the C5‐6 level (hard and soft plaque in these areas). He also had moderate stenosis of the right V4 segment.
Options include initial angioplasty and/or stenting of the cervical lesion followed by intracranial thrombectomy versus Dotter navigation of catheters through the cervical lesion to first target the intracranial LVO. The degree of cervical ICA stenosis following thrombectomy improved from 96.5%
It means either a percutaneous coronary intervention with a stent or CABG. You may be. But I am not.You need to undergo some re-vascularisation procedure. What do you mean by that Doctor ? Can I get my heart re-vascularised by drugs alone Doctor ? No we can’t. Hmmm , wait, we do have something called OMT/GDMT.
Circulation, Volume 150, Issue Suppl_1 , Page A4140682-A4140682, November 12, 2024. The left circumflex had 80% proximal stenosis with minimal luminal irregularities in the mid to distal portion. After guidewire crossing, balloon angioplasty was performed, and a drug-eluting stent was deployed.
1,2 The National Institute of Health Stroke Scale (NIHSS) cutoff for poor outcomes is lower in BAO compared to anterior circulation large vessel occlusions (LVO) due to the scale’s weighted scoring towards cortical signs.3,4 3,4 To bridge this gap, Alemseged et.al CT perfusion was without mismatch.
A stent was placed. All of Wellens' cases in his studies (1, 2) had all of: 1) preserved R-waves 2) resolution of pain 3) restored flow to the anterior wall through either a) an open artery or b) collateral circulation. Am Heart J (1989) 117 : pp 657-665. de Zwaan C., Wellens H.J.J., Am Heart J (1982) 103 : pp 730-736. Doevendans P.A.,
60-something with h/o MI and stents presented with chest pain radiating to the back and nausea/vomiting. The cath lab was activated: Result: Thrombotic 95% stenosis at the ostium of a small LPL2 with 70% stenosis at the LPL2/LPDA bifurcation in the distal/AV groove Cx Tubular 70% stenosis in the mid-circumflex.

A middle-aged male with h/o CAD and stents presented with typical chest pressure. The so-called "ST Elevation" is really the end of the QRS of Right Bundle Branch block. --Is there likely to be fixed coronary stenosis that led to demand ischemia during pneumonia? --Was This is a very common misread.
SMART 4 ( NCT04722250 ) studied patients with severe aortic stenosis and a small aortic annulus who underwent transcatheter aortic valve replacement (TAVR). The Impella CP is a catheter-based, axial flow pump that pumps blood directly from the left ventricle into the circulation. It is able to deliver 3.5L/min
The patient had no hypertension, no tachycardia, a normal hemoglobin, no drug use, no hypotension/shock, no murmur of aortic stenosis. It was opened and stented with a door to balloon time of about 120 minutes (this is long for STEMI, but very short for a high risk Non STEMI). Is it STEMI or NonSTEMI? Is it acute persistent occlusion?
Below are 6 anecdotal cases of true complete left main occlusion with no collateral circulation: 3 have STE in aVR 1 has no ST shift in aVR 2 have STD in aVR The ECG can have a variety of presentations in LM Occlusion. You'll see that there is collateral circulation from the RCA. Below is the angiogram. TIMI 0/1 flow).(61,62)
The 50-something patient with history of coronary stenting and slightly reduced LV ejection fraction. In the setting of prior stenting and reduced left ventricular ejection fraction, would pursue a heart team revascularization approach Syntax score 28.5, This alone could be due to LVH, but V4 could NOT be due to LVH.

The association of patient characteristics, aneurysm details, and procedural variables with aneurysm occlusion (RaymondRoy occlusion classifications [RROC I]), and in-stentstenosis at 1 year follow-up (FU) were tested using multivariable logistic regression analysis.Results:786 patients were analyzed. 2.56; p=0.076).
