ABSTRACT

RESUMEN La miocardiopatía hipertrófica obstructiva, es una patología de orden genético, cuyo evento más grave es la muerte súbita. El diagnóstico se basa en los hallazgos imagenológicos, constatándose un ventrículo izquierdo hipertrófico no dilatado, en ausencia de otras patologías que puedan explicar dichas alteraciones. El tratamiento médico tiene como objetivo mejorar la discapacidad funcional y el llenado diastólico, aquellos pacientes que continúan sintomáticos pese al tratamiento farmacológico, con obstrucción del tracto de salida del ventrículo izquierdo significativo, la miomectomía septal es de elección, no obstante, la ablación septal con alcohol es una alternativa a la cirugía. Se presenta una paciente de 39 años con síncope e insuficiencia cardíaca, con diagnóstico confirmado por imágenes de miocardiopatía hipertrófica asimétrica obstructiva, en quien persisten los síntomas a pesar del tratamiento médico, por lo que se realizó la ablación septal con alcohol, obteniendo resultados satisfactorios. La miocardiopatía hipertrófica obstructiva ha sido considerada como una patología poco frecuente, no obstante, en la actualidad es cada vez más diagnosticada, gracias al mayor conocimiento de su expresión fenotípica. La ablación septal con alcohol ha demostrado ser una opción segura y eficaz en nuestro medio, constituyendo una alternativa razonable de tratamiento alternativo a la cirugía, en pacientes seleccionados.


ABSTRACT Hypertrophic cardiomyopathy is a genetic disease, the most serious event of which is sudden death. Diagnosis is based on imaging findings, noting a hypertrophic undilated left ventricle, in the absence of other pathologies that may explain these alterations. The objective of the medical treatment is to improve functional disability and diastolic filling. In those patients who continue to be symptomatic despite drug treatment, with significant left ventricular outflow tract obstruction, septal myomectomy is recommended; however, septal alcohol ablation is an alternative to surgery. We present a 39-year-old patient with syncope and heart failure, with an image-confirmed diagnosis of hypertrophic obstructive cardiomyopathy, in whom symptoms persisted despite medical treatment, for which septal alcohol ablation was performed, obtaining satisfactory results. Hypertrophic obstructive cardiomyopathy has been considered a rare pathology, however, it is currently being diagnosed more and more, thanks to the greater knowledge of its phenotypic expression. Septal alcohol ablation has proven to be a safe and effective option in our setting, constituting a reasonable alternative treatment to surgery in selected patients.

ABSTRACT

background: Percutaneous septal ablation is a therapeutic option for patients with obstructive hypertrophic cardiomyopathy refrac-tory to optimal medical therapy. However, results of initial persistence and long-term safety are still controversial. Objectives: The aim of this study was to report percutaneous alcohol septal ablation technique, clinical and functional outcome, cardiovascular events and its impact on long-term follow-up. Methods: A total of 23 patients were included in the study. Functional class (FC), left ventricular outflow tract gradient before and after the procedure and long-term cardiovascular events were evaluated. results: Median follow-up was 52 months (IR 33-72). All patients were in FC III or IV prior to the procedure, under maximum tolerated medical therapy. The procedure was successful in 91% of cases, with 85% of patients currently in FC I and 15% in FC II. Baseline left ventricular outflow tract gradient decreased from 75 mmHg (95% CI 51-89) to 25 mmHg (95% CI 10-37) (p <0.003) and with Valsalva maneuver from 118 mmHg (95% CI 88-152) to 38 mmHg (95% CI 16-69) (p <0.0002), persisting in the long-term follow-up. During hospitalization, two patients presented with complete atrioventricular block requiring permanent pacemaker implantation. No cardiovascular deaths occurred during follow up. Conclusions: Alcohol septal ablation is a promising option for the treatment of a selected population with hypertrophic obstructive cardiomyopathy, generating sustained clinical and functional improvement with low incidence of events in the long-term follow up.

ABSTRACT

Objetivo: Describir nuestra experiencia y evaluar los resultados a corto y mediano plazo de la miecto-mía videoasistida en el tratamiento de la obstrucción del tracto de salida del ventrículo izquierdo (OTSVI) en pacientes con miocardiopatía hipertrófica. Materiales y métodos: 52 pacientes con edad media de 56,2 (rango 12 - 83) y Euroscore de riesgo de 4,1 +/- 1,92 con diagnóstico de OTSVI fueron intervenidos de manera consecutiva en un mismo centro mediante miectomía videoasistida. Se realizó seguimiento clínico y ecocardiográfico con controles al mes y al año del postoperatorio. Resultados: Entre las patologías asociadas encontramos 11 pacientes con valvulopatía aórtica, 2 con valvulopatía mitral, 3 con cardiopatía isquémica, 1 con aneurisma de aorta ascendente y 1 con foramen oval permeable resueltos en el mismo acto quirúrgico. La mortalidad hospitalaria global fue de 5,8 por ciento (3 pacientes). En el momento de la intervención, 8 (15,4 por ciento) se encontraban en clase funcional II de la NYHA, 42 (80,8 por ciento) en clase III y 2 (3,8 por ciento) en clase IV. El gradiente máximo subaórtico disminuyó de 80,7 mmHg +/- 29,43 en el preoperatorio a 19,0 mmHg +/- 15,57 (p<0,001) en el postoperatorio inmediato, manteniéndose en 14,6 mmHg +/- 8,88 al mes (p<0,001 en relación al preoperatorio) y al año en 13,9 mmHg +/- 7,69 (p<0,001 en relación al preoperatorio). Además, se registró una disminución del grosor del tabique interventricular en diástole de 19,4 mm +/- 3,78 en el preoperatorio a 12,9 mm +/- 2,35 (p<0,001) en el postoperatorio. Todos los pacientes se encontraban en clase funcional I-II al final del seguimiento. Conclusión: Los resultados demuestran que la miectomía videoasistida es un tratamiento seguro para la OTSVI con el que se obtienen resultados favorables a corto y mediano plazo, tanto en parámetros clínicos, como ecocardiográficos.


Aim: To report a clinical experience and to evaluate early and mid term results of video assisted myec-tomy for relief of left ventricular tract obstruction (LVOTO) in patients with Obstructive Hypertrophic Cardiomyopathy. Methods: 52 patients with Obstructive Car-diomyopathy and a mean age 56.2 years (12 - 83) carrying a Euro score risk of 4.1 +/- (SD 1.92), were consecutively operated on in a single center. Relief of LVOTO was performed with video assisted myec-tomy. Clinical and echocardiographic follow up to 1 year postoperatively was carried out. Results: Apart from the Obstructive Cardiomyo-pathy, 11 patients had aortic valve disease, 2 mitral valve disease, 3 ischemic heart disease, 1 an ascending aortic aneurysm and 1 a patent foramen ovale. All these lesions were surgically repaired in the same surgical act. In hospital mortality was 5.8 percent (3 patients). Pre-operatively 15.4 percent of patients were in NYHA Class II, 80.8 per cent in Class III and 3.8 percent in Class IV. After surgery peak sub aortic gradient decreased from 80.7+/-29.43mmHg to 19.0 +/- 15.57 (p<0.001). Corresponding values were 14.6 +/- 8.88 at 1month and 13.9 +/- 7.69 at 1 year post operatively. Interven-tricular septal thickness in diastole decreased from 19.4 +/- 3.78 mm to 12.9 +/- 2.35 mm after surgery (p<0.001). All patients were Class I or II at the end of follow up. Conclusion: Video assisted myectomy is safe and effective for relief of LVOTO in patients with hypertrophic cardiomyopathy. Good results are maintained one year after surgery.
