ABSTRACT
BACKGROUND: Various mitral valve (MV) repair techniques are nowadays in use. Non-resection techniques, that rely exclusively on Gore-Tex® neochords and annuloplasty, have been popularized; however, their efficacy in Barlow's disease, characterized by large myxomatous leaflets, is yet unclear. METHODS: Consecutive patients undergoing MV repair for Barlow's disease between 2011 and 2019 were selected on the basis of being eligible for resection and non-resection techniques. Study endpoints included overall survival, freedom from MV reintervention and recurrent regurgitation. RESULTS: Of 209 patients meeting the inclusion criteria, 135 (65%) underwent MV repair with and 74 (35%) without resection. There was one early reoperation due to residual regurgitation (resection group). Mean clinical follow-up duration was 6.1 (IQR 3.9-8.5) years. At 6 years after surgery, there was no difference in overall survival or freedom from MV reintervention. Mean echocardiographic follow-up (95% complete) duration was 3.5 (IQR 2.3-5.8) years. At 6 years, there was no difference in freedom from recurrent regurgitation rate (86.1%, 95% CI 78.5-93.7% vs. 83.0%, 95% CI 71.6-94.4%, P = 0.20) between the groups. Inverse probability-of-treatment weighting adjusted analysis demonstrated no significant difference between groups (HR 0.535, 95% CI 0.212-1.349, P = 0.20). Uni- and multivariable Cox proportional regression analysis did not demonstrate an effect of valve repair technique on the occurrence of recurrent regurgitation. CONCLUSIONS: At mid-term, the clinical and echocardiographic results of valve repair for Barlow's disease were very good and MV reintervention was rarely needed. At this time point, the results of non-resection techniques were comparable to the "gold standard" resection techniques.

INTRODUCCIÓN: Analizar las indicaciones, acciones y resultados de las operaciones realizadas en la Unidad de Cuidados Intensivos (UCI) de Cirugía Cardiovascular. MÉTODOS: Análisis retrospectivo de pacientes adultos consecutivos intervenidos en la Unidad de Cuidados Intensivos (UCI). Se incluyeron todas las intervenciones practicadas. Se realizó estadística descriptiva. RESULTADOS: Entre 2008 y 2013 se intervinieron 3379 pacientes adultos consecutivos. Se practicaron en la UCI 124 intervenciones en 109 pacientes, 70 hombres (64,2%) y 39 mujeres (35,8%) con un promedio de edad de 61,6 años (12-80). Ello ha representado un 3,2%. Durante el mismo periodo de tiempo, se intervinieron en quirófano 185 pacientes por taponamiento cardiaco/hemorragia postoperatoria (5,5%). Las intervenciones previas fueron por cardiopatía valvular (34,9%), patología aórtica (22,9%), cardiopatía isquémica (15,6%), valvular/isquémica (12%), valvular/de la aorta (11%) y miscelánea (3,6%). Las indicaciones de intervención fueron hemorragia persistente 54 (43,5%), taponamiento cardiaco 41 (33%), bajo gasto cardiaco 13 (10,5%), parada cardíaca/arritmias 8 (6,5%), insuficiencia respiratoria 6 (4,8%) e isquemia de extremidades 2 (1,7%). Las intervenciones fueron: exploración mediastínica 73 (58,9%), colocación/retirada de ECMO 17 (13,7%), cierre esternal 16 (12,9%), resucitación abierta 9 (7,3%), drenaje subxifoideo 7 (5,6%) y embolectomía femoral 2 (1,6%). La mortalidad fue 33%. Hubo un caso de mediastinitis (0,9%), sin diferencias con la tasa de infecciones profundas en pacientes no intervenidos en UCI. CONCLUSIONES: La intervención en UCI es una alternativa segura y de rescate en subgrupos específicos de pacientes. no incrementa el riesgo de infección, evita el transporte de pacientes inestables y permite ahorrar tiempo en la decisión quirúrgica postoperatoria
BACKGROUND: To analyze the indications, actions and results of the operations performed in the Cardiovascular Surgery Intensive Care Unit. METHODS: Retrospective analysis of consecutive non-selected adult patients operated in the ICU. All operations were included. Descriptive statistics were used. RESULTS: Between 2008 and 2013, 3379 consecutive adult patients were operated upon. A total of 124 operations were performed in the ICU in 109 patients, 70 male (64.2%) and 39 female (35.8%) with a mean age of 61.6 years (12-80). This represented 3.2% of all operations. During the study period, 185 patients (5.5%) were reoperated for postoperative bleeding/tamponade in the operating room. The index interventions were for valvular heart disease (34.9%), aortic disease (22.9%), ischemic heart disease (15.6%), combined valvular/ischemic (12%), valvular/aorta (11%) and miscellaneous (3.6%). The indications for reoperation were persistent bleeding 54 (43.5%), pericardial tamponade 41 (33%), low cardiac output 13 (10.5%), cardiac arrest/arrhythmia 8 (6.5%), respiratory insufficiency 6 (4.8%) and acute ischemic limb 2 (1.7%). Operations performed were: mediastinal exploration 73 (58.9%), implant/removal of ECMO 17 (13.7%), sternal closure 16 (12.9%), open resuscitation 9 (7.3%), subxyphoid drainage 7 (5.6%) and femoral embolectomy 2 (1.6%). Overall mortality was 33%. There was one case of mediastinitis (0,9%), with no difference from patients operated in the regular operating room. CONCLUSIONS: Operations in the ICU represent a safe, life-saving alternative in specific subgroups of patients. The risk of wound infection is not increased, unstable patients are not transferred and there is time savings

Introducción: La endarterectomía pulmonar (EP) es el tratamiento de elección para la hipertensión pulmonar tromboembólica crónica (HPTEC). El objetivo del estudio fue analizar nuestra experiencia en el tratamiento médico (TM) y quirúrgico de la HPTEC. Métodos: Se evaluaron 80 pacientes diagnosticados de HPTEC en el periodo enero 2000-julio 2012. En 32 casos se realizó EP, el resto recibió TM. Se analizaron: clase funcional (CF), distancia recorrida en seis minutos (PM6M) y hemodinámica pulmonar. Se analizó la mortalidad según el tratamiento y el periodo. Resultados: Los pacientes del grupo EP eran más jóvenes, mayoritariamente hombres y recorrieron mayor distancia en la PM6M. No hubo diferencias hemodinámicas ni de CF al diagnóstico. Al ano del tratamiento, el 100% del grupo EP y el 41% del grupo TM estaban en CF I-II. Al seguimiento, el grupo EP presentó mayor incremento en la PM6M y mayor reducción de la PAPm y la RVP que en el grupo TM (p < 0,05). La supervivencia global del grupo TM a 1 y 5 anos fue del 83% y del 69%, respectivamente. La supervivencia condicionada de los pacientes vivos 100 días post-EP a 1 y 5 anos fue del 95 y del 88%, respectivamente. La mortalidad quirúrgica en los pacientes operados en el período 2000-2006 fue del 31,3%, y en el período 2007-2012, del 6,3%. Conclusiones: La EP proporciona buenos resultados clínicos, hemodinámicos y de supervivencia en los pacientes que superan satisfactoriamente el postoperatorio inmediato. Tras un periodo de aprendizaje, la mortalidad perioperatoria actual en nuestro centro es superponible a los estándares internacionales
Introduction: Pulmonary endarterectomy (PE) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH). The aim of this study was to analyze our experience in the medical and surgical management of CTEPH. Methods: We included 80 patients diagnosed with CTEPH between January 2000 and July 2012. Thirty two patients underwent PE and 48 received medical treatment (MT). We analyzed functional class (FC), sixminute walking distance (6MWD) and pulmonary hemodynamics. Mortality in both groups and periods were analyzed. Results: Patients who underwent PE were younger, mostly men, and had longer 6MWD. No differences were observed in pulmonary hemodynamics or FC at diagnosis. One year after treatment, all PE patients versus 41% in MT group were at FC I-II. At follow-up, the PE group showed greater increase in 6MWD, and greater reduction in mean pulmonary arterial pressure and pulmonary vascular resistance than the MT group (P < .05). Overall survival in the MT group at 1 and 5 years was 83% and 69%, respectively. Conditional survival in patients alive 100 days post-PE at 1 and 5 years was 95% and 88%, respectively. Surgical mortality in operated patients in the first period (2000-2006) was 31,3%, and 6,3% in the second (2007-2012). Conclusions: PE provides good clinical results, and improves pulmonary hemodynamics in patients who successfully overcome the immediate postoperative period. After a learning period, the current operatory mortality in our center is similar to international standards
