Retrospective Case Control Matched Comparison of the Antegrade Versus Retrograde Strategy After Antegrade Recanalisation Failure in Complex de novo Femoropopliteal Occlusive Lesions.

OBJECTIVE: To investigate dissection severity, need for bailout stenting and limb outcomes in patients undergoing antegrade vs. retrograde revascularisation. METHODS: Consecutive patients who underwent either antegrade or retrograde revascularisation after failed antegrade recanalisation of long femoropopliteal chronic total occlusion (CTO) due to symptomatic peripheral artery disease between January 2017 and June 2022 were studied. Retrospective case control matching was used to adjust for lesion length and calcification using the peripheral artery calcification scoring system (PACSS). Procedural outcomes included severity of dissection (Type A to F dissections, numerically graded on a scale from 0 - 6 with increasing severity) after angioplasty and number and location of stents needed to be implanted during the index procedure. Additionally, clinically driven target lesion revascularisation (CD-TLR) and major (above ankle) amputation rates were assessed during follow up. RESULTS: A total of 180 patients were analysed who underwent antegrade (n = 90) or retrograde after failed antegrade (n = 90) recanalisation. The median patient age was 76.0 (interquartile range [IQR] 67.0, 82.0) years and 76 (42.2%) were female. Moreover, 78 patients (43.3%) had intermittent claudication, whereas 102 (56.7%) had chronic limb threatening ischaemia (CLTI). The mean lesion length was 30.0 (IQR 24.0, 36.0) cm with moderate to severe (3.0 [IQR 2.0, 4.0]) lesion calcification. Dissection severity after angioplasty was higher in the antegrade than retrograde after failed antegrade recanalisation group (4.0 [IQR 3.0, 4.0] vs. 3.0 [IQR 2.0, 4.0]; p < .001). Additionally, the number of stents in all segments and the rate of bailout stenting in popliteal segments was significantly higher with the antegrade strategy (2.0 [IQR 1.0, 3.0] vs. 1.0 [IQR 0, 2.0], p < .010; and 37% vs. 14%, p < .001). During a median follow up of 1.48 (IQR 0.63, 3.09) years, CD-TLR rates (p = .90) and amputation rates in patients with CLTI (p = .15) were not statistically significant. CONCLUSION: In complex femoropopliteal CTOs, retrograde after failed antegrade recanalisation, is safe for endovascular revascularisation, which in experienced hands may result in less severe dissections and lower rates of stent placement. However, considering the relatively short follow up, CD-TLR and amputation rates were not statistically different between the two approaches. [German Clinical Trials Register: DRKS00015277.].

Diagnostic Pathway From Incidental Mass to Metastatic Melanoma: Role of Multimodal Imaging and Medical Therapy.

We present a case of detection of a right atrial mass during surveillance echocardiography, mimicking myxoma. Cardiac magnetic resonance and computed tomography revealed infiltration into the pericardium, suggesting malignancy. Abdominal computed tomography showed multiple liver masses that were histologically positive for metastatic amelanotic melanoma. Under immunotherapy adequate remission was achieved.

Multi-parametric non-contrast cardiac magnetic resonance for the differentiation between cardiac amyloidosis and hypertrophic cardiomyopathy.

AIM: To evaluate the ability of fast strain-encoded (SENC) cardiac magnetic resonance (CMR) derived myocardial strain and native T1 mapping to discriminate between hypertrophic cardiomyopathy (HCM) and cardiac amyloidosis. METHODS: Ninety nine patients (57 with hypertrophic cardiomyopathy and 42 with cardiac amyloidosis) were systematically analysed. LV-ejection fraction, LV-mass index, septal wall thickness and native T1 mapping values were assessed. In addition, global circumferential and longitudinal strain and segmental circumferential and longitudinal strain in basal, mid-ventricular, and apical segments were calculated. A ratio was built by dividing native T1 values by basal segmental strain (T1-to-basal segmental strain ratio). RESULTS: Myocardial strain was equally distributed in apical and basal segments in HCM patients, whereas an apical sparing with less impaired apical strain was noticed in cardiac amyloidosis (apical-to-basal-ratio of 1.01 ± 0.23 versus 1.20 ± 0.28, p < 0.001). T1 values were significantly higher in amyloidosis compared to HCM patients (1170.7 ± 66.4 ms versus 1078.3 ± 57.4ms, p < 0.001). The T1-to-basal segmental strain ratio exhibited high accuracy for the differentiation between the two clinical entities (Sensitivity = 85%, Specificity = 77%, AUC = 0.90, 95% CI = 0.81-0.95, p < 0.001). Multivariable analysis showed that age and the T1-to-basal-strain-ratio were the most robust factors for the differentiation between HCM and cardiac amyloidosis. CONCLUSION: The T1-to-basal-segmental strain ratio, combining information from segmental circumferential and longitudinal strain and native T1 mapping aids the differentiation between HCM and cardiac amyloidosis with high accuracy and within a fast CMR protocol, obviating the need for contrast agent administration.

Endovascular Versus Surgical Treatment for All Comer Patients With Prosthetic Bypass Graft Occlusion: The Multicentre ENSUPRO Study.

OBJECTIVE: Bypass surgery plays a key role in complex lower limb lesions. However, there is a lack of evidence regarding the management of symptomatic prosthetic bypass graft (PBG) occlusion. This study aimed to report outcomes following open, hybrid, or endovascular management of patients presenting with symptomatic PBG occlusion. METHODS: A multicentre, retrospective cohort study was conducted, including patients presenting with PBG occlusion between January 2014 and December 2021 from 18 centres. It assessed the comparative value of treatment strategies, including (1) recanalisation of native vessels, (2) endovascular treatment of the failed PBG, (3) hybrid treatment, and (4) open surgery. The primary outcome measure was amputation free survival (AFS, time to major amputation and or death), whereas all cause mortality, major amputation, PBG re-occlusion, target lesion revascularisation (TLR), and Rutherford category (RC) improvement during follow up were considered as secondary endpoints. RESULTS: Of 260 patients with occluded PBGs, 108 (41.5%) were treated endovascularly (24 [22.2%] by recanalisation of native vessels and 84 [77.7%] by PBG re-opening), 57 (21.9%) underwent hybrid revascularisation, and 58 (22.3%) had surgery. In addition, 27 (10.4%) were treated conservatively and 10 (3.8%) received systemic thrombolysis. With a median follow up of 1.4 (0.6 - 3.0) years, AFS was 95.5%, 76.4%, 45.5%, and 37.1%, respectively in Groups 1 - 4 (p = .007). Older age and non-endovascular treatment (HR 1.05 and 1.70; p < .01 for both) were independent predictors of poor AFS. Endovascular treatment was associated with lower rates of major amputation (p = .04), PBG re-occlusion (p < .001), and TLR (p = .037), and higher RC improvements (p < .001), whereas all cause mortality was comparable between treatment groups (p = .21). CONCLUSION: Endovascular treatment is associated with higher rates of AFS and RC improvement and lower rates of PBG re-occlusion and TLR in patients with PBG occlusion.

A case report of distal radial puncture in a patient with acute upper limb ischaemia: the last hope of the cardiologist?

Background: Patients with acute limb ischaemia (ALI) present with acute symptoms, requiring prompt diagnosis and expedited treatment to preserve the viability of the affected ischaemic tissue. Case summary: We present an 83-year-old female patient with upper ALI due to thrombotic occlusion of the left brachial artery. Concomitantly, the patient had a first diagnosis of atrial fibrillation and was not on treatment with oral anticoagulation. Transfemoral thrombectomy using a 6F Rotarex® catheter resulted in removal of the thrombus from the brachial artery. However, significant amounts of debris embolized distally, causing occlusion of both the radial and ulnar arteries. The debris was successfully removed after puncture of the distal radial artery and retrograde thrombus aspiration using a 5F Envoy catheter. This manoeuver led to flow restoration in both the radial and ulnar arteries and to complete resolution of ischaemic symptoms of the patient. Discussion: Interventionists may consider distal radial puncture not only as an access site for coronary angiography but also as an option for the endovascular management of ALI in cases of cardiac embolism, as described herein or in cases of thrombotic complications during routine catheterization and percutaneous coronary intervention. Herein, we describe the case of an 83-year-old patient, who presented with acute upper limb ischaemia. Due to embolization of thrombotic debris during Rotarex® catheter thrombectomy, flow further diminished in the ulnar and radial arteries. The last hope for successful interventional treatment was thrombectomy from distally after retrograde puncture of the distal radial artery. This unique manoeuver led to flow restoration and complete recovery of the patient without the need for open surgery.

A Systematic Review and Meta-Analysis on the Efficacy and Safety of Direct Oral Anticoagulants in Patients with Peripheral Artery Disease.

BACKGROUND: PAD is a significant cause of morbidity and mortality affecting over 200 million people worldwide. Current guidelines recommend at least a single antiplatelet or anticoagulant agent in symptomatic PAD and lifelong antithrombotic treatment after a revascularization procedure. The aim of this systematic review and meta-analysis was to investigate the efficacy and safety of direct oral anticoagulants (DOACs) in patients with peripheral artery disease (PAD). PAD is a significant cause of morbidity and mortality affecting over 200 million people worldwide. METHODS: The present systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Risk ratios (RR) were calculated using the random effects model. RESULTS: Overall, 10 studies were included in this systematic review and meta-analysis. In 4 studies, 14,257 patients with PAD were enrolled and they were assigned to receive either aspirin (ASA)+/- clopidogrel (N = 5,894) or DOAC+/- anti-platelet (e.g., ASA, clopidogrel) (n = 8,363). Non DOAC users were found to have higher reintervention rates (RR 1.12; 95% CI 1.01-1.24; P = 0.025) compared to DOAC users. No statistically significant difference was observed between the 2 groups, in terms of major bleeding (RR 0.78; 95% CI 0.50-1.23; P = 0.285), all-cause mortality (RR 0.98; 95% CI: 0.83-1.16; P = 0.818) and cardiovascular mortality (RR: 0.99; 95% CI: 0.73-1.333; P = 0.946) mortality. In addition, two real-world studies comparing DOAC with warfarin showed decreased rates of major cardiovascular events in the DOAC group. CONCLUSION: DOAC use alone or combined with an anti-platelet agent could be associated with lower re-intervention rates, without increasing the risk for adverse bleeding events. However, this study failed to detect any difference in terms of all-cause mortality, MACEs and MALEs between DOAC users and DOAC naïve patients. Future studies are needed to better determine the efficacy and safety of DOACs in patients with PAD.

Retrograde use of the Outback re-entry catheter in complex infrainguinal arterial recanalizations.

OBJECTIVE/BACKGROUND: Retrograde recanalizations gained increasing recognition in complex arterial occlusive disease. Re-entry devices are a well-described adjunct for antegrade recanalizations. We present our experience with retrograde, infrainguinal recanalizations using the Outback re-entry catheter in challenging chronic total occlusions. METHODS: We report data from a retrospective multicenter registry in complex retrograde recanalizations. Eligibility criteria included retrograde infrainguinal use of the Outback re-entry catheter where both conventional antegrade and retrograde recanalizations had been unsuccessful. Procedural outcomes included technical success (defined as successful wire passage and delivery of adjunctive therapy with <30% residual stenosis), safety (periprocedural complications, eg, bleeding, vessel injury, or occlusion of the artery at the re-entry site, and distal embolizations), and clinical outcome (amputation-free survival and freedom from clinically driven target lesion revascularization [cd-TLR]). RESULTS: Forty-five consecutive patients underwent retrograde, infrainguinal recanalization attempts with the Outback re-entry catheter between February 2015 and August 2020. Thirty (67%) patients had a history of open vascular surgery in the index limb. In four patients, recanalizations were even more challenging due to previous surgical removal and/or ligation of the proximal segment of the superficial femoral artery. The retrograde access site of the Outback catheter was the femoropopliteal segment in 31 (69%) patients and crural vessels in 14 (31%) patients. The re-entry target sites were as follows: common femoral artery in 31 (69%) patients, superficial femoral artery in 9 (20%) patients, popliteal artery in 1 patient, and below-the-knee arteries in 2 patients. In four patients, the needle of the re-entry device was targeted to an inflated balloon, inserted via the antegrade route. The Outback re-entry catheter was placed via a 6-French sheath in 19 (42%) cases and sheathless in 26 (58%) cases. Technical success was achieved in 41 (91%) patients There were two instances of distal embolizations and three bleeding episodes. Amputation-free survival was 100% at 30 days, and after 12 months, freedom from cd-TLR was 95% at 30 days and 75% at 12 months of follow-up. Female sex was an independent predictor for cd-TLR at 12 months of follow-up. CONCLUSIONS: Retrograde use of the Outback re-entry catheter in infrainguinal chronic total occlusions provides an effective and safe endovascular adjunct, when conventional antegrade and retrograde recanalization attempts have failed.

Relationship Between Quality of Life Indicators and Cardiac Status Indicators in Chemotherapy Patients.

AIM: With the aim of improving personalized treatment of patients on chemotherapy, the objective of the study was to assess the degree of association between selected Quality of life (QoL) indicators and both clinical and imaging cardiac status indicators when detecting deterioration in QoL of these patients. METHODS: In a cohort clinical study in Hamburg, from August 2017 through October 2020, 59 cancer patients, aged 18-80 years, were evaluated before chemotherapy, and at several follow-ups, using EQ-5D and SF-36 QoL questionnaires, fast strain-encoded (fast-SENC) cardiac magnetic resonance (CMR), conventional CMR, and echocardiography, and further received a clinical and biomarker examination. Data was analyzed using survival analyses. A decline of more than 5% in each observed QoL metric value was defined as the observed event. Patient were separated into groups according to the presentation of cardiotoxicity as per its clinical definition, the establishment of the indication for cardioprotective therapy initiation, and by a worsening in the value of each observed imaging metric by more than 5% in the previous follow-up compared to the corresponding pre-chemotherapy baseline value. RESULTS: Among clinical cardiac status indicators, the indication for cardioprotective therapy showed statistically good association with QoL scores (EQ-5D p=0.028; SF-36 physical component p=0.016; SF-36 mental component p=0.012). In terms of imaging metrics, the MyoHealth segmental myocardial strain score was the only one demonstrating consistently good QoL score association (EQ-5D p=0.005; SF-36 physical component p=0.056; SF-36 mental component p=0.002). CONCLUSIONS: Established fast-SENC CMR scores are capable of highlighting patients with reduced QoL, who require more frequent/optimal management.

Fast-Strain Encoded Cardiac Magnetic Resonance During Vasodilator Perfusion Stress Testing.

Background: Cardiac magnetic resonance perfusion imaging during vasodilator stress is an established modality in patients with suspected and known coronary artery disease (CAD). Aim: This study aimed to evaluate the performance of fast-Strain-Encoded-MRI (fast-SENC) for the diagnostic classification and risk stratification of patients with ischemic heart disease. Methods: Perfusion and fast-SENC cardiac magnetic resonance (CMR) images were retrospectively analyzed in 111 patients who underwent stress CMR. The average myocardial perfusion score index, global and segmental longitudinal and circumferential strain (GLS and GCS and SLS and SCS, respectively), were measured at rest and during stress. The combination of SLS and SCS was referred to as segmental aggregate strain (SAS). Segments exhibiting perfusion defects or SAS impairment during stress were defined as "ischemic." All-cause mortality, non-fatal infarction, and urgent revascularization were deemed as our combined clinical endpoint. Results: During adenosine stress testing, 44 of 111 (39.6%) patients exhibited inducible perfusion abnormalities. During a mean follow-up of 1.94 ± 0.65 years, 25 (22.5%) patients reached the combined endpoint (death in n = 2, infarction in n = 3 and urgent revascularization in n = 20). Inducible perfusion defects were associated with higher number of segments with inducible SAS reduction ≥6.5% (χ2 = 37.8, AUC = 0.79, 95% CI = 0.71-0.87, p < 0.001). In addition, patients with inducible perfusion defects or SAS impairment exhibited poorer outcomes (AUCPerf = 0.81 vs. AUCSAS = 0.74, p = NS vs. each other, and χ2 = 30.8, HR = 10.3 and χ2 = 9.5, HR = 3.5, respectively, p < 0.01 for both). Conclusion: Purely quantitative strain analysis by fast-SENC during vasodilator stress was related to the diagnosis of ischemia by first-pass perfusion and is non-inferior for the risk stratification of patients with ischemic heart disease. This may bear clinical implications, especially in patients with contraindications for contrast agent administration.

Diagnostic Work-Up of Cardiac Amyloidosis Using Cardiovascular Imaging: Current Standards and Practical Algorithms.

Among non-ischemic cardiomyopathies, cardiac amyloidosis is one of the most common, being caused by extracellular depositions of amyloid fibrils in the myocardium. Two main forms of cardiac amyloidosis are known so far, including 1) light-chain (AL) amyloidosis caused by monoclonal production of light-chains, and 2) transthyretin (ATTR) amyloidosis, caused by dissociation of the transthyretin tetramer into monomers. Both AL and ATTR amyloidosis are progressive diseases with median survival from diagnosis of less than 6 months and 3 to 5 years, respectively, if untreated. In this regard, death occurs in most patients due to cardiac causes, mainly congestive heart failure, which can be prevented due to the presence of effective, life-saving treatment regimens. Therefore, early diagnosis of cardiac amyloidosis is crucial more than ever. However, diagnosis of cardiac amyloidosis may be challenging due to variable clinical manifestations and the perceived rarity of the disease. In this regard, clinical and laboratory reg flags are available, which may help clinicians to raise suspicion of cardiac amyloidosis. In addition, advances in cardiovascular imaging have already revealed a higher prevalence of cardiac amyloidosis in specific populations, so that the diagnosis especially of ATTR amyloidosis has experienced a >30-fold increase during the past ten years. The goal of our review article is to summarize these findings and provide a practical approach for clinicians on how to use cardiovascular imaging techniques, such as echocardiography, cardiac magnetic resonance, bone scintigraphy and, if required, organ biopsy within predefined diagnostic algorithms for the diagnostic work-up of patients with suspected cardiac amyloidosis. In addition, two clinical cases and practical tips are provided in this context.

Multi-parametric assessment of left ventricular hypertrophy using late gadolinium enhancement, T1 mapping and strain-encoded cardiovascular magnetic resonance.

AIM: To evaluate the ability of single heartbeat fast-strain encoded (SENC) cardiovascular magnetic resonance (CMR) derived myocardial strain to discriminate between different forms of left ventricular (LV) hypertrophy (LVH). METHODS: 314 patients (228 with hypertensive heart disease (HHD), 45 with hypertrophic cardiomyopathy (HCM), 41 with amyloidosis, 22 competitive athletes, and 33 healthy controls) were systematically analysed. LV ejection fraction (LVEF), LV mass index and interventricular septal (IVS) thickness, T1 mapping and atypical late gadolinium enhancement (LGE) were assessed. In addition, the percentage of LV myocardial segments with strain ≤ - 17% (%normal myocardium) was determined. RESULTS: Patients with amyloidosis and HCM exhibited the highest IVS thickness (17.4 ± 3.3 mm and 17.4 ± 6 mm, respectively, p < 0.05 vs. all other groups), whereas patients with amyloidosis showed the highest LV mass index (95.1 ± 20.1 g/m2, p < 0.05 vs all others) and lower LVEF compared to controls (50.5 ± 9.8% vs 59.2 ± 5.5%, p < 0.05). Analysing subjects with mild to moderate hypertrophy (IVS 11-15 mm), %normal myocardium exhibited excellent and high precision, respectively for the differentiation between athletes vs. HCM (sensitivity and specificity = 100%, Area under the curve; AUC%normalmyocardium = 1.0, 95%CI = 0.85-1.0) and athletes vs. HHD (sensitivity = 83%, specificity = 75%, AUC%normalmyocardium = 0.85, 95%CI = 0.78-0.90). Combining %normal myocardial strain with atypical LGE provided high accuracy also for the differentiation of HHD vs. HCM (sensitivity = 82%, specificity = 100%, AUCcombination = 0.92, 95%CI = 0.88-0.95) and HCM vs. amyloidosis (sensitivity = 83%, specificity = 100%, AUCcombination = 0.83, 95%CI = 0.60-0.96). CONCLUSION: Fast-SENC derived myocardial strain is a valuable tool for differentiating between athletes vs. HCM and athletes vs. HHD. Combining strain and LGE data is useful for differentiating between HHD vs. HCM and HCM vs. cardiac amyloidosis.

Multiparametric Early Detection and Prediction of Cardiotoxicity Using Myocardial Strain, T1 and T2 Mapping, and Biochemical Markers: A Longitudinal Cardiac Resonance Imaging Study During 2 Years of Follow-Up.

BACKGROUND: Our goal was to evaluate the ability of cardiovascular magnetic resonance for detecting and predicting cardiac dysfunction in patients receiving cancer therapy. Left ventricular ejection fraction, global and regional strain utilizing fast-strain-encoded, T1 and T2 mapping, and cardiac biomarkers (troponin and BNP [brain natriuretic peptide]) were analyzed. METHODS: Sixty-one patients (47 with breast cancer, 11 with non-Hodgkin lymphoma, and 3 with Hodgkin lymphoma) underwent cardiovascular magnetic resonance scans at baseline and at regular intervals during 2 years of follow-up. The percentage of all left ventricular myocardial segments with strain ≤-17% (normal myocardium [%]) was analyzed. Clinical cardiotoxicity (CTX) and sub-CTX were defined according to standard measures. RESULTS: Nine (15%) patients developed CTX, 26 (43%) had sub-CTX. Of the 35 patients with CTX or sub-CTX, 24 (69%) were treated with cardioprotective medications and showed recovery of cardiac function. The amount of normal myocardium (%) exhibited markedly higher accuracy for the detection of CTX and sub-CTX compared with left ventricular ejection fraction, T1, and T2 mapping as well as troponin I (Δareas under the curve=0.20, 0.24, and 0.46 for normal myocardium (%) versus left ventricular ejection fraction, troponin I, and T1 mapping, P<0.001 for all). In addition, normal myocardium (%) at baseline accurately identified patients with subsequent CTX (P<0.001), which was not achieved by any other markers. CONCLUSIONS: Normal myocardium (%) derived by fast-strain-encoded cardiovascular magnetic resonance, is an accurate and sensitive tool that can establish cardiac safety in patients with cancer undergoing cardiotoxic chemotherapy not only for the early detection but also for the prediction of those at risk of developing CTX.

Left and right ventricular strain using fast strain-encoded cardiovascular magnetic resonance for the diagnostic classification of patients with chronic non-ischemic heart failure due to dilated, hypertrophic cardiomyopathy or cardiac amyloidosis.

AIMS: To compare the ability of left ventricular (LV) and right ventricular (RV) strain measured by fast-strain encoded cardiovascular magnetic resonance (CMR) (fast-SENC) with LV- and RV-ejection fraction for the diagnostic classification of patients with different stages of chronic heart failure (stages A-D based on American College of Cardiology/American Heart Association guidelines) due to non-ischemic cardiomyopathies. METHODS: Our study population consisted of 276 consecutive patients who underwent CMR for clinical reasons, and 19 healthy subjects. Wall motion score index and non-infarct related late gadolinium enhancement (LGE), LV ejection fraction (LVEF) and RV ejection fraction (RVEF) and global LV- and RV-longitudinal (GLS) and circumferential strain (GCS) based on fast-SENC acquisitions, were calculated in all subjects. The percentage of LV and RV myocardial segments with strain ≤ - 17% (%normal LV and RV myocardium) was determined in all subjects. RESULTS: LVEF and RVEF, LV-GLS, LV-GCS, RV-GLS, RV-GCS and %normal LV- and RV myocardium depressed with increasing heart failure stage (p < 0.001 for all by ANOVA). By multivariable analysis, %normal LV and RV myocardium exhibited closer associations to heart failure stages than LVEF and RVEF (rpartial = 0.79 versus rpartial = 0.21 for %normal LV myocardium versus LVEF and rpartial = 0.64 versus rpartial = 0.20 for %normal RV myocardium versus RVEF, respectively). Furthermore, %normal LV and RV myocardium exhibited incremental value for the identification of patients (i) with subclinical myocardial dysfunction and (ii) with symptomatic heart failure, surpassing that provided by LVEF and RVEF (ΔAUC = 0.22 for LVEF and ΔAUC = 0.19 for RVEF with subclinical dysfunction, and ΔAUC = 0.19 for LVEF and ΔAUC = 0.22 for RVEF with symptomatic heart failure, respectively, p < 0.001 for all). %normal LV myocardium reclassified 11 of 31 (35%) patients judged as having no structural heart disease by clinical and imaging data to stage B, i.e., subclinical LV-dysfunction. CONCLUSIONS: In patients with non-ischemic cardiomyopathy, %normal LV and RV myocardium, by fast-SENC, enables improved identification of asymptomatic patients with subclinical LV-dysfunction. This technique may be useful for the early identification of such presumably healthy subjects at risk for heart failure and for monitoring LV and RV deformation during pharmacologic interventions in future studies.

The Real-World CONSEQUENT ALL COMERS Study: Predictors for Target Lesion Revascularization and Mortality in an Unselected Patient Population.

We evaluated the safety and efficacy of a resveratrol-paclitaxel-coated peripheral balloon catheter in an all-comer patient cohort undergoing endovascular treatment of above-the-knee and below-the-knee peripheral artery disease. CONSEQUENT ALL COMERS (Clinical Post-Market Clinical Follow-up [PMCF] on Peripheral Arteries treated with SeQuent Please OTW [Over-the Wire]) is a prospective, single-arm, multicenter observational study (ClinicalTrials Identifier: NCT02460042). The primary end point was the 12-month target lesion revascularization (TLR) rate. Secondary end points included vessel patency, target vessel revascularization, and all-cause mortality. A total of 879 lesions in 784 consecutive patients (71.3 ± 10.4 years old, 57.7% male) were analyzed; 53.3% had claudication, whereas the remaining 46.7% exhibited critical limb ischemia (CLI). Substantial comorbidities were present, including diabetes mellitus (41.2%), smoking (66.1%), and coronary artery disease (33.9%). Lesion length (879 lesions) was 12.0 ± 9.3 cm and 31.8% were Transatlantic Inter-Society Consensus II C/D lesions. The overall technical success rate of the 1269 drug-coated balloon (DCB)'s used was 99.6% (1.60 ± 0.79 DCB's/patient). At 12 months, the TLR rates were 6.3% in patients with CLI and 9.6% in claudicants, with a primary patency rate of 89.9% and 87.1%, respectively. All-cause mortality was 4.3% (28/658). The most important predictors for TLR were female gender, in-stent restenosis at baseline and lesion length.
