RESUMO

Introducción y objetivos: La calcificación grave está presente en más del 50% de las oclusiones coronarias crónicas totales (OCT) tratadas mediante intervención percutánea. Nuestro objetivo fue describir el uso contemporáneo de los dispositivos de modificación de placa (DMP) en este contexto. Métodos: Los pacientes se incluyeron en el Registro Ibérico de OCT de forma prospectiva y consecutiva (32 centros de España y Portugal), de 2015 a 2020. Se compararon en función del uso o no de DMP. Resultados: Se incluyó a 2.235 pacientes, en 1.900 de los cuales se logró cruzar con éxito la lesión con guía. Se utilizó al menos un DMP en un 7% (134 pacientes) y más de uno en 24 pacientes (1%). Los DMP seleccionados fueron: aterectomía rotacional (35,1%), litotricia (5,2%), láser (11,2%), balones de corte (27,6%), balones OPN (2,9%) o combinaciones de más de uno (18%). Se utilizaron DMP en pacientes más ancianos, con mayor riesgo cardiovascular y puntuaciones Syntax y J-CTO más elevados. Esta mayor complejidad se asoció con procedimientos más prolongados, pero similar longitud total de stent (52 frente a 57mm; p=0,105). Cuando la guía cruzó con éxito la oclusión, la tasa de éxito final del procedimiento fue del 87,2%, pero se incrementó al 96,3% cuando se utilizaron DMP (p=0,001). Por el contrario, los DMP no se asociaron con mayor tasa de complicaciones en el procedimiento (3,7 frente a 3,2%; p=0,615). Pese al peor perfil de riesgo basal, a los 2 años de seguimiento no hubo diferencias en la tasa de supervivencia (94,3% DPM frente a no-DMP: 94,3% no-DPM, respectivamente, p=0,967). Conclusiones: Cuando la guía cruzó con éxito una OCT, la tasa de uso de los DMP fue del 7% y se asoció a una tasa de éxito final del procedimiento significativamente mayor. Los resultados a medio plazo fueron comparables cuando se precisaron DMP pese a su mayor riesgo basal, lo que sugiere que un mayor uso adecuado de estas técnicas en este contexto (AU)


Introduction and objectives: Severe calcification is present in> 50% of coronary chronic total occlusions (CTOs) undergoing percutaneous intervention. We aimed to describe the contemporary use and outcomes of plaque modification devices (PMDs) in this context. Methods: Patients were included in the prospective, consecutive Iberian CTO registry (32 centers in Spain and Portugal), from 2015 to 2020. Comparison was performed according to the use of PMDs. Results: Among 2235 patients, wire crossing was achieved in 1900 patients and PMDs were used in 134 patients (7%), requiring more than 1 PMD in 24 patients (1%). The selected PMDs were rotational atherectomy (35.1%), lithotripsy (5.2%), laser (11.2%), cutting/scoring balloons (27.6%), OPN balloons (2.9%), or a combination of PMDs (18%). PMDs were used in older patients, with greater cardiovascular burden, and higher Syntax and J-CTO scores. This greater complexity was associated with longer procedural time but similar total stent length (52 vs 57mm; P=.105). If the wire crossed, the procedural success rate was 87.2% but increased to 96.3% when PMDs were used (P=.001). Conversely, PMDs were not associated with a higher rate of procedural complications (3.7 vs 3.2%; P=.615). Despite the worse baseline profile, at 2 years of follow-up there were no differences in the survival rate (PMDs: 94.3% vs no-PMDs: 94.3%, respectively; P=.967). Conclusions: Following successful wire crossing in CTOs, PMDs were used in 7% of the lesions with an increased success rate. Mid-term outcomes were comparable despite their worse baseline profile, suggesting that broader use of PMDs in this setting might have potential technical and prognostic benefits (AU)

RESUMO

OBJECTIVE: Myocardial damage that is associated with percutaneous coronary intervention (PCI) partially affects the results of the procedure, and is related to medium-term cardiovascular death. Remote postischemic conditioning might reduce the myocardial lesions that are associated with PCI, but perhaps less so in diabetics. The aim of this study was to evaluate the protective effect of remote postischemic conditioning in patients undergoing elective PCI for stable angina or non-ST elevation acute coronary syndrome with troponin <1 ng/ml at the time of randomization. METHODS: This randomized single-blinded single-center clinical trial involved 320 patients undergoing elective PCI who were randomized to either receive three 5-min cycles of ischemia by inflation of a cuff on the non-dominant arm to 200 mm Hg (remote postischemic conditioning) or to placebo (uninflated cuff). The primary outcome variable was the maximum increase in troponin in the first 24 h. The secondary outcome variable was readmission due to heart failure or cardiovascular mortality after 1 year of follow-up. In addition, a diabetic population was studied. CONCLUSIONS: This clinical trial evaluated the possible reduction in intervention-related myocardial damage that was attributable to remote postischemic conditioning.

RESUMO

Las complicaciones mecánicas son unos de los más indeseables contratiempos que pueden aparecer en el infarto agudo de miocardio (IAM) y, a pesar de su baja incidencia (en gran parte gracias a la aparición de tratamientos de revascularización precoz eficaces como la angioplastia primaria), la gravedad que confieren necesita un rápido y acertado diagnóstico y un tratamiento precoz. Las tres clases principales de complicaciones mecánicas son las comunicaciones interventriculares tras el IAM, la rotura libre de pared de ventrículo izquierdo y la insuficiencia mitral aguda severa secundaria a rotura de músculo papilar. Su aparición suele ser precoz, dentro de las primeras 48 h desde el inicio de los síntomas del infarto y, generalmente, se asocia a enfermedad coronaria oclusiva en ausencia de colaterales. Su pronóstico es malo, con mortalidades de más del 50% y el tratamiento de elección es la cirugía, a pesar de que en determinados casos, como la comunicación interventricular, se están desarrollando técnicas percutáneas con resultados prometedores (AU)


Mechanical complications are among the worst phenomena that can occur with acute myocardial infarction. Although they are not common (thanks largely to the introduction of effective early reperfusion therapy such as primary angioplasty), their seriousness means that they have to be quickly and accurately diagnosed and treated as soon as possible. The three main forms of mechanical complication are post-infarct ventricular septal rupture, rupture of the left ventricular free wall, and acute severe mitral regurgitation secondary to rupture of the papillary muscle. They usually appear early within the first 48 hours after symptom onset and are generally associated with occlusive coronary artery disease in the absence of collaterals. The prognosis is poor, mortality is greater than 50%, and surgery is the treatment of choice. However, a number of percutaneous techniques have been developed that show promising results in some cases, such as ventricular septal rupture (AU)
