ABSTRACT
INTRODUCTION: Complete revascularization (CR) in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), is associated with a reduction in major adverse cardiovascular events (MACE). However, there is uncertainty about whether nonculprit-lesion revascularization should be performed, during index hospitalization or delayed, especially regarding health care resources utilization. In this study, we aimed to evaluate the impact of in-hospital nonculprit-lesion revascularization vs. delayed (after discharge) revascularization on the length of index hospitalization. METHODS: In this single-center study, we randomly assigned patients with STEMI and MVD who underwent successful culprit-lesion PCI to a strategy of either CR during in-hospital admission or a delayed CR after discharge. The first primary endpoint was the length of hospital stay. The second endpoint was the composite of cardiovascular death, myocardial infarction or ischemia-driven revascularization at 12 months (MACE). RESULTS: From January 2018 to December 2022, we enrolled 258 patients (131 allocated to CR during in-hospital admission and 127 to an after-discharge CR). We found a significant reduction in the length of hospital stay in those assigned to after-discharge CR strategy [4 days (3-5) versus 7 days (5-9); p = 0.001]. At 12-month of follow-up, no differences were found in the occurrence of MACE, 7 (5.34%) patients in in-hospital CR and 4 (3.15%) in after-discharge CR strategy; (hazard ratio, 0.59; 95% confidence interval, 0.17 to 2.02; p = 0.397). CONCLUSIONS: In STEMI patients with MVD, an after-discharge CR strategy reduces the length of index hospitalization without an increased risk of MACE after 12 months of follow-up.

Introduction and objectives Catheter-directed therapy (CDT) for acute pulmonary embolism (PE) is an emerging therapy that combines heterogeneous techniques. The aim of the study was to provide a nationwide contemporary snapshot of clinical practice and CDT-related outcomes. Methods This Investigator-initiated multicenter registry aimed to include consecutive patients with intermediate-high risk (IHR) or high-risk (HR), acute PE eligible for CDT. The primary outcome of the study was in-hospital all-cause death. Results A total of 253 patients were included, of whom 93 (36.8%) had HR-PE, and 160 (63.2%) had IHR-PE with a mean age of 62.3±15.1 years. Local thrombolysis was performed in 70.8% and aspiration thrombectomy in 51.8%, with 23.3% of patients receiving both. However, aspiration thrombectomy was favored in the HR-PE cohort (80.6% vs 35%; P<.001). Only 51 patients (20.2%) underwent CDT with specific PE devices. The success rate for CDT was 90.9% (98.1% of IHR-PE patients vs 78.5% of HR-PE patients, P<.001). In-hospital mortality was 15.5%, and was highly concentrated in the HR-PE patients (37.6%) and significantly lower in IHR-PE patients (2.5%), P<.001. Long-term (24-month) mortality was 40.2% in HR-PE patients vs 8.2% in IHR-PE patients (P<.001). Conclusions Despite the high success rate for CDT, in-hospital mortality in HR-PE is still high (37.6%) compared with very low IHR-PE mortality (2.5%) (AU)
Introducción y objetivos El emergente tratamiento por catéter (TPC) de la embolia pulmonar (EP) aguda combina técnicas heterogéneas. El objetivo del estudio es describir la práctica clínica contemporánea y los resultados relacionados con la TPC en un registro de ámbito nacional. Métodos Registro multicéntrico iniciado por investigador, destinado a incluir a pacientes con EP aguda consecutivos y en riesgo intermedio-alto (IAR) o alto riesgo (AR) elegibles para TPC. El resultado primario del estudio fue la muerte por cualquier causa en el hospital. Resultados Se incluyó en total a 253 pacientes, 93 (36,8%) con EP-AR y 160 (63,2%) con EP-IAR, de una media de edad de 62,3±15,1. Se realizó trombolisis local al 70,8% de los pacientes, trombectomía aspirativa al 51,8% y ambas al 23,3%. Sin embargo, la trombectomía por aspiración fue más frecuente en la cohorte de EP-AR (el 80,6 frente al 35%; p<0,001). Solo 51 pacientes (20,2%) se sometieron a TPC con dispositivos específicos de EP. El éxito de la TPC fue del 90,9% (el 98,1% de los casos de EP-IAR frente al 78,5% de los de EP-AR; p<0,001). La mortalidad hospitalaria fue del 15,5%, muy concentrada en los casos de EP-AR (37,6%) y significativamente menor entre los de EP-IAR (2,5%; p<0,001). La mortalidad a largo plazo (24 meses) fue del 40,2 en EP-AR frente al 8,2% en EP-IAR (p<0,001). Conclusiones A pesar del elevado éxito de la TPC, la mortalidad hospitalaria por EP-AR sigue siendo alta (37,6%) respeto a la muy baja mortalidad de la EP-IAR (2,5%) (AU)

INTRODUCTION: The benefit of complete revascularization (CR) on long-term total event reduction in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), still remains unclear. We assessed the efficacy of three different revascularization strategies on long-term total recurrent events. METHODS: We retrospectively analyzed 414 consecutive patients admitted with STEMI and MVD who were categorized according to the revascularization strategy used: culprit-vessel-only percutaneous coronary intervention (PCI) (n=163); in-hospital CR (n=136); and delayed CR (n=115). The combined endpoint assessed was all-cause mortality, the total number of myocardial infarctions, ischemia-driven revascularizations or strokes. Negative binomial regression was used to assess the association between the revascularization strategy and total events; risk estimates were expressed as an incidence rates ratio (IRR). RESULTS: At a median follow-up of four years (1.2-6), rates of the combined endpoint per 10 patient-years were 18, 0.8, and 0.6 in culprit-vessel-only PCI, in-hospital CR, and delayed CR strategies, respectively (p<0.001). After multivariable adjustment and when compared with culprit-vessel-only PCI, both in-hospital and delayed CR strategies were significantly associated with a reduction in the combined endpoint (IRR=0.40: 95% confidence interval (CI), 0.25-0.64; p<0.001; and IRR 0.40: 95% CI, 0.24-0.62; p<0.001, respectively). No differences were observed across in-hospital and delayed CR strategies. CONCLUSIONS: Complete revascularization of non-culprit lesions in patients with STEMI and MVD reduces the risk of total recurrent events during long-term follow-up. No differences between in-hospital and delayed CR strategies were found.

BACKGROUND: It is unknown whether the availability of long drug-eluting stents modify the PCI strategy of long CTO. To describe the contemporary PCI strategy of long chronic total occlusions (CTO) using overlapping (OS) or single long stents (SS) and to analyze its results. METHODS: 2842 consecutive CTO PCIs were included. Those with an occlusion length ≥20 mm in which ≥1 drug eluting stent (DES) was implanted were analyzed. We compared procedural characteristics and clinical outcomes of CTO treated with OS or SS. RESULTS: 1088 CTO PCIs were analyzed (79.9% males; 64.7±10.6 years). Mean J-score was 2.8±0.9. A SS was used in 38.5% of cases and OS in 61.5%. Total stent length was 64.1±29.9 mm; it was higher in the OS group (OS: 79.9±25.5 mm vs. SS: 38.3±14.7 mm; P<0.0001). Mean number of stents in the OS group was 2.3±1. Very long stents (≥40 mm) were used in 27.4% of cases, more frequently in the OS group (OS:32.4% vs. SS:19.3%; P<0.0001). After a mean follow-up of 19±15.9 months, the rate of adverse events (MACE) was 2% (cardiac death: 1.6%, myocardial infarction: 1.6%, target lesion revascularization: 1.9% and stent thrombosis: 0.18%) with no significant differences between both groups. Overlapping was not an independent predictor of MACE. CONCLUSIONS: In long CTO PCIs, OS is more frequently used than single stenting, especially in more complex procedures. Clinical outcomes at a mid-term follow-up are favorable. Using newer generation DES, overlapping was not an independent predictor of MACE; however, a trend toward a higher event rate was observed in the OS group.

Pulmonary vascular resistance (PVR) is a marker of pulmonary vascular remodeling. A non-invasive model assessed by cardiovascular magnetic resonance (CMR) has been proposed to estimate PVR. However, its accuracy has not yet been evaluated in patients with heart failure. We prospectively included 108 patients admitted with acute heart failure (AHF), in whom a right heart catheterization (RHC) and CMR were performed at the same day. PVR was estimated by CMR applying the model: PVR = 19.38 - [4.62 × Ln pulmonary artery average velocity (in cm/s)] - [0.08 × right ventricle ejection fraction (in %)], and by RHC using standard formulae. The median age of the cohort was 67 years (interquartile range 58-73), and 34% were females. The median of PVR assessed by RHC and CMR were 2.2 WU (1.5-4) and 5 WU (3.4-7), respectively. We found a weak correlation between invasive PVR and PVR assessed by CMR (Spearman r = 0.21, p = 0.02). The area under the ROC curve for PVR assessed by CMR to detect PVR ≥ 3 WU was 0.57, 95% confidence interval (CI): 0.47-0.68. In patients with AHF, the non-invasive estimation of PVR using CMR shows poor accuracy, as well as a limited capacity to discriminate increased PVR values.

BACKGROUND: We aimed to compare the performance of the recent CASTLE score to J-CTO, CL and PROGRESS CTO scores in a comprehensive database of percutaneous coronary intervention of chronic total occlusion procedures. METHODS: Scores were calculated using raw data from 1,342 chronic total occlusion procedures included in REBECO Registry that includes learning and expert operators. Calibration, discrimination and reclassification were evaluated and compared. RESULTS: Mean score values were: CASTLE 1.60±1.10, J-CTO 2.15±1.24, PROGRESS 1.68±0.94 and CL 2.52±1.52 points. The overall percutaneous coronary intervention success rate was 77.8%. Calibration was good for CASTLE and CL, but not for J-CTO or PROGRESS scores. Discrimination: the area under the curve (AUC) of CASTLE (0.633) was significantly higher than PROGRESS (0.557) and similar to J-CTO (0.628) and CL (0.652). Reclassification: CASTLE, as assessed by integrated discrimination improvement, was superior to PROGRESS (integrated discrimination improvement +0.036, p<0.001), similar to J-CTO and slightly inferior to CL score (- 0.011, p = 0.004). Regarding net reclassification improvement, CASTLE reclassified better than PROGRESS (overall continuous net reclassification improvement 0.379, p<0.001) in roughly 20% of cases. CONCLUSION: Procedural percutaneous coronary intervention difficulty is not consistently depicted by available chronic total occlusion scores and is influenced by the characteristics of each chronic total occlusion cohort. In our study population, including expert and learning operators, the CASTLE score had slightly better overall performance along with CL score. However, we found only intermediate performance in the c-statistic predicting chronic total occlusion success among all scores.

Introducción y objetivos: El impacto de la intervención coronaria percutánea (ICP) sobre oclusiones coronarias crónicas totales (OCT) presenta controversias. Se analizan los resultados agudos y al seguimiento en nuestro entorno. Métodos: Registro prospectivo de ICP sobre OCT en 24 centros durante 2 años. Resultados: Se realizaron 1.000 ICP sobre OCT en 952 pacientes. La mayoría tenía síntomas (81,5%) y cardiopatía isquémica previa (59,2%), y hubo intentos de desobstrucción previos en un 15%. El SYNTAX anatómico fue 19,5 +/- 10,6 y tenía J-score > 2 el 17,3%. El procedimiento fue retrógrado en 92 pacientes (9,2%). La tasa de éxito fue del 74,9%, mayor en aquellos sin ICP previa (el 82,2 frente al 75,2%; p = 0,001), con J-score ≤ 2 (el 80,5 frente al 69,5%; p = 0,002) y con el uso de ecografía intravascular (el 89,9 frente al 76,2%; p = 0,001), que fue predictor independiente del éxito. Por el contrario, lesiones calcificadas, > 20 mm o con muñón proximal romo lo fueron de fracaso. El 7,1% tuvo complicaciones, como perforación (3%), infarto (1,3%) o muerte (0,5%). Al año de seguimiento, el 88,2% mejoró clínicamente en caso de ICP exitosa (frente al 34,8%; p < 0,001). Dicha mejoría se asoció con menor mortalidad. La tasa de mortalidad al año fue del 1,5%. Conclusiones: Los pacientes del Registro Ibérico con OCT tratados con ICP presentan complejidad clínico-anatómica, tasas de éxito y complicaciones similares a los de otros registros nacionales e importante impacto de la recanalización exitosa en la mejoría funcional, que a su vez se asoció con menor mortalidad
Introduction and objectives: There is current controversy regarding the benefits of percutaneous recanalization (PCI) of chronic total coronary occlusions (CTO). Our aim was to determine acute and follow-up outcomes in our setting. Methods: Two-year prospective registry of consecutive patients undergoing PCI of CTO in 24 centers. Results: A total of 1000 PCIs of CTO were performed in 952 patients. Most were symptomatic (81.5%), with chronic ischemic heart disease (59.2%). Previous recanalization attempts had been made in 15%. The mean SYNTAX score was 19.5 +/- 10.6 and J-score was > 2 in 17.3%. A retrograde procedure was performed in 92 patients (9.2%). The success rate was 74.9% and was higher in patients without previous attempts (82.2% vs 75.2%; P = .001), those with a J-score ≤ 2 (80.5% vs 69.5%; P = .002), and in intravascular ultrasound-guided PCI (89.9% vs 76.2%, P = .001), which was an independent predictor of success. In contrast, severe calcification, length > 20mm, and blunt proximal cap were independent predictors of failed recanalization. The rate of procedural complications was 7.1%, including perforation (3%), myocardial infarction (1.3%), and death (0.5%). At 1-year of follow-up, 88.2% of successfully revascularized patients showed clinical improvement (vs 34.8%, P < .001), which was associated with lower mortality. At 1-year of follow-up, the mortality rate was 1.5%. Conclusions: Compared with other national registries, patients in the Iberian registry undergoing PCI of a CTO showed similar complexity, success rate, and complications. Successful recanalization was strongly associated with functional improvement, which was related to lower mortality

BACKGROUND: Percutaneous coronary intervention (PCI) of chronic total occlusions (CTO) usually involves multiple overlapping stents implantation to cover long coronary segments. A higher rate of restenosis has been described with stent overlapping. Recently, new long tapered stents emerged as a potential tool for treating long coronary lesions. Feasibility of using these new devices for the CTO PCI has not been described. The aim of this work was to describe our initial experience with 50 and 60â¯mm-long tapered sirolimus-eluting stents (SES) in CTO PCI. METHODS: We included 54 consecutive patients who underwent a CTO PCI and in whom an attempt to implant a 50 or 60â¯mm-long tapered SES was performed. Baseline clinical, angiographic, and procedural characteristics were recorded. RESULTS: The median (IQR) age was 64 (58-73) years, and 45 (83.3%) patients were male. The tapered SES 50 and 60â¯mm-long was successfully implanted in 51 (94.4%) patients. In three patients, a 60â¯mm-long stent could not be implanted, and two or three overlapped shorter drug-eluting stents were deployed instead. An average of 1.4⯱â¯0.6 stents per patient was implanted. A single stent was deployed in 32 (59.3%) patients. During a median follow-up of 330 (149-551) days, repeat PCI in the target vessel was performed in two patients. CONCLUSIONS: The use of the new BioMime Morph™ tapered SES for the treatment of CTO appears to be feasible in a high proportion of procedures. Further studies confirming the feasibility of this approach and its potential clinical advantages are needed.

BACKGROUND: Optimal management strategy for patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD) still remains unclear, especially in the elderly population. The aim of this study was to assess long-term outcomes and predictors of morbi-mortality according to age in patients with a STEMI and MVD. METHODS: We prospectively included 381 consecutive patients with a STEMI who underwent primary angioplasty and showed MVD in the angiogram. 111 (29.1%) patients were older than 75 (≥75) years and 270 (70.9%) were younger than 75 (<75) years. The co-primary outcomes were the incidence of all-cause mortality and major adverse cardiac events (MACE) during follow-up. RESULTS: During a median follow-up of 22 months, patients ≥75 years showed a higher incidence of all-cause mortality and MACE, as compared to younger patients. On multivariate analysis, incomplete revascularization (IR) was only an independent predictor of MACE (HR = 3.1, CI 95%:1.9-4.7; P = .02) in younger patients; whereas in the elderly group severely depressed ejection fraction was the unique independent predictor of MACE (HR = 2.7, CI 95%:1.5-4.8; P = .001). IR was not associated with the risk of all-cause mortality in any group. CONCLUSION: This study confirms the relevant prevalence of MVD in STEMI patients, as well as the difference in outcomes of an IR strategy between both age-groups, being only independently associated with MACE in younger patients. This finding supports that a routine complete revascularization (CR) strategy seems to be the best therapeutic option in younguer patients, whereas in the elderly population may not confer a clear clinical benefit during a long-term follow-up.

OBJECTIVE: The aim of this case report is to highlight the importance of excluding aortic coarctation in a patient with a bicuspid aortic valve. CLINICAL PRESENTATION AND INTERVENTION: A 56-year-old woman with hypertension was admitted complaining of progressive dyspnea. Transthoracic echocardiography showed a calcified, bicuspid aortic valve with severe stenosis. Aortography revealed the presence of severe narrowing of the aorta between the carotid and subclavian arteries. The patient was referred for cardiovascular surgery in which successful aortic valve replacement and aortic correction were performed. CONCLUSION: This case report shows an uncommon finding of infantile aortic coarctation in an adult patient admitted with heart failure.

OBJECTIVE: The aim of this case report was to highlight the importance of ruling out pheochromocytoma in a patient with Von Hippel-Lindau disease (VHL) and cardiovascular manifestations. CLINICAL PRESENTATION AND INTERVENTION: A 22-year-old woman with type IIb VHL presented with signs and symptoms of acute decompensated heart failure. Transthoracic echocardiography showed a dilated left ventricle with severely depressed ejection fraction, confirmed by MRI. Urinary catecholamine and metanephrine tests had elevated levels and an abdominal MRI showed the presence of two cystic masses at the left hypochondrium. Surgical resection of both masses was performed, confirming the diagnosis of pheochromocytoma and clear cell renal carcinoma on histology. Six-month echocardiography showed a left ventricle with normal diameters and preserved ejection fraction. Genetic analysis revealed a germline mutation (exon 3 deletion of VHL). As there was no family history of VHL, it was determined to be a de novo mutation. CONCLUSION: This case report showed an atypical manifestation in a patient with VHL and underlines the importance of screening for pheochromocytoma in such patients.

BACKGROUND: Early stratification of patients according to the risk for developing microvascular obstruction (MVO) after ST-segment elevation myocardial infarction (STEMI) is desirable. We aimed to identify predictors of cardiovascular magnetic resonance (CMR)-derived MVO from clinical+ECG, laboratory and angiographic parameters available on admission. METHODS: Characteristics available on admission were documented in 97 STEMI patients referred for primary angioplasty. MVO was determined using contrast-enhanced CMR. RESULTS: MVO was present in 44 patients (45%). The C-statistic for predicting MVO was: clinical+ECG (.832), laboratory (.743), and angiographic parameters (.669). Adding laboratory to clinical+ECG information did not improve the C-statistic (.873 vs. .832, p=.2). Further addition of angiographic data (.904) improved the C-statistic of clinical+ECG (p=.04) but not of clinical+ECG and laboratory (p=.2). Independent predictors of MVO using clinical and ECG parameters were: Killip class >1 (OR 15.97 95%CI [1.37-186.76], p=.03), diabetes (OR 6.15 95%CI [1.49-25.39], p=.01), age <55years (OR 4.70 95%CI [1.56-14.17], p=.006), sum of ST-segment elevation >10mm (OR 4.5 95%CI [1.58-12.69], p=.005) and delayed presentation >3h (OR 3.80 95%CI [1.19-12.1], p=.02). A score was constructed assigning Killip class >1 2 points and the remaining indexes 1 point. The incidence of MVO increased with the score: 0 point: 8.7%; 1 point: 28.1%; 2 points: 71.4%; and 3+ points: 93% (p<.0001). CONCLUSIONS: MVO can be predicted using parameters already available on patient admission. We developed a clinical-ECG score allowing for early and reliable classification of STEMI patients according to the risk of MVO.

AIMS: The implantation of an implantable loop recorder (ILR) leads to the diagnosis in about 35% of patients with syncope of unknown origin. Information on outcome of patients in whom a diagnosis is not reached during the lifetime of the device is scarce. The aim of our study is to determine the outcome of these patients in terms of syncope recurrence and survival. METHODS AND RESULTS: An ILR was implanted to 97 patients with syncope of unknown origin. Patients were classified in groups A and B depending on their high or low risk, respectively, of having arrhythmic syncope. Diagnosis had not been reached in 60 patients (62%) when the ILR battery reached end operational life. Five patients were lost to follow up. During a median follow-up of 48 months after ILR explantation (interquartile range 36-56), 22 patients (40%) had recurrence of syncope (32% in group A vs. 48% in group B, P = 0.3). Syncopes with no neurally mediated profile were more frequent in group A (18 vs. 0%, P = 0.05) and neurally mediated profile syncopes were more frequent in group B (44 vs. 11%, P = 0.007). Five patients died, four of them in group A and 1 in group B (P = 0.4). No sudden or cardiac deaths were detected during follow-up. All deaths were due to non-cardiac causes. CONCLUSION: Recurrent syncope is common in patients in whom a diagnosis is not established after the full battery life of an ILR. The prognosis of these patients seems to be good, without observed sudden or cardiac death.
