Project description:BackgroundIn recent years, the retrograde approach has become a common practice in the treatment of chronic total occlusion (CTO) of coronary ostium which is arising abnormally and has an ambiguous proximal cap. In this case report, we report a case of retrograde percutaneous coronary intervention (PCI) done successfully on an abnormally originating artery which was guideliner assisted. Case Presentation. A 65-year-old gentleman with a history of hypertension, diabetes, and PCI presented to us with angina. Physical examination, electrocardiography (ECG), and echocardiography were done. Coronary angiography (CAG) revealed a normal left anterior descending artery (LAD), an anomalous circumflex (CX) artery arising from the right cusp. The abnormal CX had an implanted stent from which the abnormal right coronary artery (RCA) was arising and had a CTO. It also revealed the retrograde filling of distal RCA through grade 2 Werner collateral channels (CCs) from the LAD, a long CTO segment with a distal cap at the bifurcation. PCI of an RCA-CTO was scheduled utilizing a primary retrograde strategy, since antegrade ostium was abnormal in origin, and the patient was previously stented across the origin. The retrograde wire was externalized, and the procedure was completed with 3 overlapping drug-eluting stents (DESs). We used a guideliner which also assisted in the capture of retrograde corsair during the retrograde procedure of CTO [assisted reverse controlled antegrade and retrograde tracking (CART)]. These measures helped us to complete the CTO intervention successfully.ConclusionThe antegrade crossing is the most common approach to CTOs. However, it is sometimes difficult to penetrate the proximal hard ambiguous cap with guidewires, especially in the case of CTOs of anomalous coronary arteries because of a lack of support. Herein, we describe an iteration of reverse CART technique using a guide extensor catheter to facilitate externalizing the retrograde wire from false to true lumen.

Project description:We present a clinical case of early occlusion of the non-infarct-related artery (non-IRA) in a patient with ST-elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (pPCI). Several hours after successful percutaneous treatment of the occluded right coronary artery the patient developed a second myocardial infarction, which was caused by acute occlusion of the left anterior descending artery, which had a significant lesion in the proximal segment. The lesion was diagnosed during the first catheterization, but was left untreated. We discuss the potential advantages and risks associated with the ad-hoc multivessel PCI strategy in STEMI.

Project description:BackgroundIn patients with acute ST-segment elevation myocardial infarction (STEMI) who undergo primary percutaneous coronary intervention (PCI), approximately 10% are concomitant with a chronic total occlusion (CTO) in a non-culprit vessel. However, the impact of staged CTO recanalization on prognosis in this cohort remains disputable. This study aimed to compare the long-term outcomes of staged CTO recanalization versus medical therapy in patients with STEMI after primary PCI.MethodsBetween January 2005 and December 2016, a total of 287 patients were treated with staged CTO-PCI (n = 91) or medical therapy (n = 196) after primary PCI in our center. The primary endpoint was major adverse cardiovascular and cerebrovascular event (MACCE), defined as a composite of all-cause death, nonfatal myocardial infarction (MI), stroke or unplanned revascularization. After propensity-score matching, 77 pairs of well-balanced patients were identified.ResultsThe mean follow-up period was 6.06 years. Overall, the incidence of the primary endpoint of MACCE was significantly lower in staged CTO-PCI group than that in medical therapy group in both overall population (22.0% vs. 46.9%; hazard ratio (HR) = 0.48, 95% CI: 0.29-0.77) and propensity-matched cohorts (22.1% vs. 42.9%; HR: 0.48, 95% CI: 0.27-0.86). In addition, staged CTO-PCI was also associated with reduced risk of the composite of cardiac death, nonfatal MI or stroke compared with medical therapy in both overall population (9.9% vs. 26.5%; hazard ratio (HR) = 0.39, 95% CI: 0.19-0.79) and propensity-matched cohorts (9.1% vs. 22.1%; HR: 0.40, 95% CI: 0.16-0.96). After correction of the possible confounders, staged CTO-PCI was independently associated with reduced risks of MACCE (adjusted HR: 0.46, 95% CI: 0.28-0.75), the composite of cardiac death, nonfatal MI or stroke (adjusted HR: 0.45, 95% CI: 0.22-0.94) and all-cause mortality (adjusted HR: 0.32, 95% CI: 0.13-0.83). Moreover, the results of sensitivity analysis were almost concordant with the overall analysis.ConclusionsIn patients with STEMI and a concurrent CTO who undergo primary PCI, successful staged recanalization of CTO in the non-culprit vessels is associated with better clinical outcomes during long-term follow-up.

Project description:BackgroundEvidence from randomized controlled trials has shown a benefit for endovascular treatment in basilar artery occlusion. We aimed to show the effect of the recanalization result on outcome and determine the role of underlying basilar stenosis in a real-world setting.MethodsA retrospective, single-center study of patients who received endovascular treatment for basilar artery occlusion from March 2008 to June 2022 was conducted. Clinical and outcome characteristics were gathered. Multivariate logistic regression analysis was performed to predict poor outcomes (post-treatment mRS 5 or 6). MRS shift analysis was performed.ResultsThis study includes 210 patients (mean age, 71.4 years +/- 13.3 [standard deviation]; 124 men). The variables age (OR, 1.04; 95% CI: 1.01-1.08; p = 0.014), underlying basilar stenosis (OR: 4.86; 95% CI: 2.15-10.98; p < 0.001), admission NHISS (OR: 1.09; 95% CI: 1.04-1.13; p < 0.001), and TICI (OR: 1.89; 95% CI: 1.09-3.25; p = 0.022) independently predicted a poor outcome. Patients with occlusions due to underlying stenosis had significantly worse recanalization rates. Median post-treatment mRS in all patients with embolic occlusion was 4; IQR, 2-5 (only patients with embolic occlusion: mTICI 0-2a, median: 5 [IQR, 4-5.5]; mTICI 2b, median: 4 [IQR, 2.5-6]; mTICI 3, median: 3 [IQR, 1-5]; p = 0.037). Median post-treatment mRS in all patients with occlusions due to underlying stenosis was 5; IQR, 4-6 (only patients with embolic occlusions: mTICI 0-2a, median: 6 [IQR, 4.5-6]; mTICI 2b, median: 6 [IQR, 4.25-6]; mTICI 3, median: 5 [IQR, 3.5-5.25]; p = 0.059).ConclusionsSuccessful recanalization is essential for preventing poor outcomes in basilar artery occlusion. Underlying basilar stenosis diminishes the effect of successful recanalization on the overall outcome.

Project description:BackgroundRadial artery occlusion (RAO) often occurs after catheterization when using a transradial artery approach.ObjectiveThis prospective study assessed the success and feasibility of accessing the distal transradial artery (dTRA) for retrograde recanalization of RAO.MethodsFrom June 2019 to December 2021, 44 consecutive patients who had undergone cardiac catheterization resulting in RAO were given retrograde recanalization via the dTRA. According to the result of the procedure (primary endpoint), patients' cases were analyzed as successful or failed. Rates of post-operative patency and adverse events were calculated up to 12 months.ResultsThe procedural success rate was 88.6%. Compared with the successful group, a significantly higher percentage of patients in the failed group were current smokers and/or suffered from diabetes mellitus (each, 80.0% cf. 33.3%, P = 0.046); had undergone at least 3 previous cardiac catheterizations (60.0% cf. 12.8%, P = 0.011), lower rate of anticoagulation (30.77% cf. 0%, P = 0.048) and exhibited chronic total occlusion (100.0% cf. 51.28%, P = 0.041). In each group, one patient each had minor bleeding at the access site and hematoma. The patency rates in the successful group at postoperative 3, 6, and 12 months were 48.7, 43.6, and 35.9%, respectively.ConclusionThe dTRA approach for retrograde recanalization of RAO showed a high procedural success rate, but with patency rates of <50% at follow-up.

Project description:Endovascular therapy (EVT) was performed in two cases with chronic total occlusion (CTO) of superficial femoral artery. In these cases, angioscopy was deployed in the backyard of the CTO lesion from popliteal artery retrogradely, then the guidewire was advanced from antegrade. When the wire crossed the distal of the CTO lesion, the wire penetration was clearly visualized by the retrograde-angioscopy. Therefore, wire crossing of CTO into the distal true lumen was certainly confirmed, and EVT was successful. <Learning objective: Angioscopy-guided endovascular therapy for chronic total occlusion was useful not only to evaluate thrombus and plaque in situ visually, but also to successfully perform guidewire crossing.>.

Project description:RationaleCoronary perforation leading to fistula directed to the right ventricle is a rare complication of percutaneous coronary intervention (PCI). The reported outcomes vary from a stable state to rapid deterioration.Patient concernsAn 86-year-old man was diagnosed with non-ST elevation myocardial infarction, and arranged to PCI procedure for the chronic total occluded right coronary artery (RCA) after coronary angiography. The guide wire went through the occluded lesion and got to the distal part of the suspected "post lateral artery", which later proved to be in the right ventricle (RV). After dilating with a 2.0 mm balloon, large amount of contrast medium leaked out from the lesion; therefore, we suspected a perforation into the pericardium.InterventionProtamine was intravenously injected to convert the effect of heparin and the 2.0 mm balloon in diameter was dilated for about 1 h to obstruct the ejected blood flow shunting into the pericardium, but the leakage persisted. Nevertheless, the patient remained stable, and we were unable to detect an effusion in the pericardium.DiagnosisBy analyzing the angiogram and echocardiogram, we found that the contrast did not leak into the pericardium, but into the right ventricle (RV) chamber. An iatrogenic coronary artery fistula (ICAF) from the RCA to the RV was confirmed. We thus terminated the procedure.OutcomesCoronary computed tomography (CT) angiography was performed 2 days after the PCI and no abnormal shunt was found. There was no abnormal Doppler signal in the RV, either. The patient was soon discharged, and there have been no complaints of discomfort during the 10-month follow-up.LessonsICAFs from coronary to the RV always have favorable outcomes. Even like the one in this case that caused medium leakage could seal spontaneously without any additional management. Echocardiography or coronary CT angiography could be chosen as imaging options to follow-up ICAFs.
