Impact of Tricuspid Regurgitation Severity and Repair on Aortic Valve Replacement.

BACKGROUND: Aortic stenosis is one of the most prevalent valve diseases but is rarely accompanied by tricuspid regurgitation. Our objective was to analyze the impact of tricuspid regurgitation severity and its surgical treatment on prognosis of patients undergoing aortic valve replacement. METHODS: This was a retrospective cohort study including all patients presenting with aortic stenosis with some degree of tricuspid regurgitation between 2001 and 2018. Patients were grouped according to the degree of tricuspid regurgitation. RESULTS: From a sample of 8080 patients with aortic stenosis, 143 (1.8%) presented with more than trace tricuspid regurgitation. Among patients with mild, moderate, or severe tricuspid regurgitation, we observed no differences in 30-day (15.1% vs 14.8% vs 8.7%; P = .727), 12-month (51.2% vs 56% vs 55%; P = .892), or 5-year (64% vs 73.3% vs 66.7%; P = .798) survival. Aortic valve replacement plus tricuspid annuloplasty, when compared with aortic valve replacement only was associated with longer intensive care unit stay (9 vs 3 days; P = .043) but not higher 30-day (0% vs 15.5%; P = .112), 12-month (38.5% vs 54.3%; P = .278), or 5-year mortality (57.1% vs 67.1%; P = .594). Only history of liver disease and postoperative major morbidity were independent predictors of survival 30 days, 12 months and 5 years after surgery. CONCLUSIONS: Severity of tricuspid regurgitation in patients with aortic stenosis was not associated with increased mortality. Tricuspid annuloplasty did not improve survival in this subset of patients but was associated with increased postoperative morbidity.

Unidad de cuidados intermedios tras la cirugía cardiaca: impacto en la estancia media y la evolución clínica / Intermediate care unit after cardiac surgery: impact on length of stay and outcomes

Introducción y objetivos: El posoperatorio de cirugía cardiaca incluye el traslado desde la unidad de cuidados intensivos (UCI) a la sala convencional. Las unidades de cuidados intermedios (UCIn) permiten la optimización de recursos hospitalarios. Se ha analizado el impacto de una UCIn en las estancias medias (en la UCI y hospitalaria) y los resultados (mortalidad hospitalaria y reingresos a los 30 días) tras la cirugía cardiaca (UCIn-CC). Métodos: Desde noviembre de 2012 hasta abril de 2015, ingresaron para cirugía cardiaca 1.324 pacientes consecutivos. Se implementó una UCIn-CC (mayo de 2014). Los pacientes se clasificaron en 2 grupos: pre-UCIn-CC (noviembre de 2012 a abril de 2014; n = 674) y post-UCIn-CC (mayo de 2014 a abril de 2015; n = 650). Resultados: No se observaron diferencias significativas en edad, sexo, factores de riesgo, EuroSCORE 2, fracción de eyección o tipo de cirugía (el 53% valvular, el 26% coronaria, el 11,5% valvular y coronaria y el 1,8% de aorta). La estancia en la UCI disminuyó del pre-UCIn-CC al post-UCIn-CC una media ± desviación estándar de 4,9 ± 11 a 2,9 ± 6 días (p < 0,001); de una mediana [Q1-Q3] de 2 [1-4] a 1 [0-3]; la estancia hospitalaria disminuyó de 13,5 ± 15 a 12,7 ± 11 días (p = 0,01); de 9 [7-13] a 9 [7-11]. No hubo diferencias estadísticamente significativas en la mortalidad intrahospitalaria (4,9 frente al 3,5%; p = 0,28) ni la readmisión a 30 días (4,3 frente al 4,2%; p = 0,89). Conclusiones: Tras la implementación de una UCIn-CC para el cuidado del posoperatorio de cirugía cardiaca, se observó una reducción de las estancias medias en la UCI y hospitalaria, sin que aumentaran la mortalidad hospitalaria ni los reingresos a los 30 días

Introduction and objectives: Current postoperative management of adult cardiac surgery often comprises transfer from the intensive care unit (ICU) to a conventional ward. Intermediate care units (IMCU) permit hospital resource optimization. We analyzed the impact of an IMCU on length of stay (both ICU and in-hospital) and outcomes (in-hospital mortality and 30-day readmissions) after adult cardiac surgery (IMCU-CS). Methods: From November 2012 to April 2015, 1324 consecutive patients were admitted to a university hospital for cardiac surgery. In May 2014, an IMCU-CS was established for postoperative care. For the purposes of this study, patients were classified into 2 groups, depending on the admission period: pre-IMCU-CS (November 2012-April 2014, n = 674) and post-IMCU-CS (May 2014-April 2015, n = 650). Results: There were no statistically significant differences in age, sex, risk factors, comorbidities, EuroSCORE 2, left ventricular ejection fraction, or the types of surgery (valvular in 53%, coronary in 26%, valvular plus coronary in 11.5%, and aorta in 1.8%). The ICU length of stay decreased from 4.9 ± 11 to 2.9 ± 6 days (mean ± standard deviation; P < .001); 2 [1-4] to 1 [0-3] (median [Q1-Q3]); in-hospital length of stay decreased from 13.5 ± 15 to 12.7 ± 11 days (mean ± standard deviation; P = .01); 9 [7-13] to 9 [7-11] (median [Q1-Q3]), in pre-IMCU-CS to post-IMCU-CS, respectively. There were no statistically significant differences in in-hospital mortality (4.9% vs 3.5%; P = .28) or 30-day readmission rate (4.3% vs 4.2%; P = .89). Conclusions: After the establishment of an IMCU-CS for postoperative cardiac surgery, there was a reduction in ICU and in-hospital mean lengths of stay with no increase in in-hospital mortality or 30-day readmissions

Intermediate Care Unit After Cardiac Surgery: Impact on Length of Stay and Outcomes.

The ICU length of stay decreased from 4.9±11 to 2.9±6 days (mean±standard deviation; P<.001); 2 [1-4] to 1 [0-3] (median [Q1-Q3]); in-hospital length of stay decreased from 13.5±15 to 12.7±11 days (mean±standard deviation; P=.01); 9 [7-13] to 9 [7-11] (median [Q1-Q3]), in pre-IMCU-CS to post-IMCU-CS, respectively. There were no statistically significant differences in in-hospital mortality (4.9% vs 3.5%; P=.28) or 30-day readmission rate (4.3% vs 4.2%; P=.89). CONCLUSIONS: After the establishment of an IMCU-CS for postoperative cardiac surgery, there was a reduction in ICU and in-hospital mean lengths of stay with no increase in in-hospital mortality or 30-day readmissions.

A multicentre Spanish study for multivariate prediction of perioperative in-hospital cerebrovascular accident after coronary bypass surgery: the PACK2 score.

OBJECTIVES: To develop a multivariate predictive risk score of perioperative in-hospital stroke after coronary artery bypass grafting (CABG) surgery. METHOD: A total of 26 347 patients were enrolled from 21 Spanish hospital databases. Logistic regression analysis was used to predict the risk of perioperative stroke (ictus or transient ischaemic attack). The predictive scale was developed from a training set of data and validated by an independent test set, both selected randomly. The assessment of the accuracy of prediction was related to the area under the ROC curve. The variables considered were: preoperative (age, gender, diabetes mellitus, arterial hypertension, previous stroke, cardiac failure and/or left ventricular ejection fraction<40%, non-elective priority of surgery, extracardiac arteriopathy, chronic kidney failure and/or creatininemia≥2 mg/dl and atrial fibrillation) and intraoperative (on/off-pump). RESULTS: Global perioperative stroke incidence was 1.38%. Non-elective priority of surgery (priority; OR=2.32), vascular disease (arteriopathy; OR=1.37), cardiac failure (cardiac; OR=3.64) and chronic kidney failure (kidney; OR=6.78) were found to be independent risk factors for perioperative stroke in uni- and multivariate models in the training set of data; P<0.0001; AUC=0.77, 95% CI 0.73-0.82. The PACK2 stroke CABG score was established with 1 point for each item, except for chronic kidney failure with 2 points (range 0-5 points); AUC=0.76, 95% CI 0.72-0.80. In patients with PACK2 score≥2 points, off-pump reduced perioperative stoke incidence by 2.3% when compared with on-pump CABG. CONCLUSIONS: PACK2 risk scale shows good predictive accuracy in the data analysed and could be useful in clinical practice for decision making and patient selection.

Off-pump surgery in preventing perioperative stroke after coronary artery bypass grafting: a retrospective multicentre study.

OBJECTIVES: To determine the effect of the off-pump technique in preventing stroke development during the early perioperative period after coronary artery bypass graft surgery (CABG). METHODS: Patients undergoing isolated CABG surgery were enrolled from 21 Spanish cardiac-surgery centres. Baseline variables related to perioperative stroke risk were recorded in the preoperative (age, gender, diabetes mellitus, arterial hypertension, prior stroke, cardiac failure: preoperative New York Heart Association class III-IV and/or left ventricular ejection fraction <40%, non-elective priority of surgery, peripheral arteriopathy, chronic renal failure) and intraoperative periods (on/off-pump performance). The Northern New England Cardiovascular Disease Study Group (NNECDSG) stroke risk schema was used to stratify stroke risk and compare observed neurological outcomes in this study. RESULTS: A total of 26 347 patients were included in the study. Global perioperative stroke incidence was 1.38%. Non-elective priority of surgery (OR = 2.37), peripheral arteriopathy (OR = 1.62), cardiac failure (OR = 2.98), prior stroke (OR = 1.57) and chronic renal failure (OR = 6.16) were found to be independent risk factors for perioperative stroke in uni- and multivariate models; Hosmer-Lemeshow test: χ(2) = 4.62, P = 0.59. Perioperative stroke incidence increased whenever NNECDSG score or the number of preoperative risk factors increased. However, on- vs off-pump surgery did not show statistical differences in NNECDSG strata. For patients with two or more preoperative independent risk factors, off-pump surgery showed a significant reduction in perioperative stroke incidence (4.29 vs 6.76%, P < 0.05), particularly when one of these factors was chronic renal failure or preoperative cardiac failure. However, when both factors were present concomitantly there was no difference between on and off-pump techniques, P < 0.0001. CONCLUSIONS: Off-pump surgery has a lower perioperative stroke incidence than on-pump only in cases associated with cardiovascular stroke-risk factors, in particular, with chronic renal failure and preoperative cardiac failure, but also with peripheral arteriopathy, prior stroke and non-elective surgery. The perioperative stroke rate remains high in cases with two or more preoperative stroke risk factors, even when using the off-pump technique, particularly when chronic renal failure is present.

Survival, clinical status and quality of life five years after coronary surgery. The ARCA study.

INTRODUCTION AND OBJECTIVES: Little is known about the long-term outcomes of coronary surgery and their determinants in Spain. The objectives of this study were to evaluate clinical outcomes, quality of life and survival in a cohort of patients 5 years after undergoing a first aortocoronary bypass operation without any other associated procedure. METHODS: Patients who survived the operation and whose pre- and postoperative data had been collected prospectively were followed up by telephone interview after 5 years. RESULTS: Information was available after 5 years on 1,300 (85.2%) of the 1,525 patients who survived until hospital discharge. Of these, 13.6% had died, while 24% had either died, undergone revascularization or were readmitted because of a cardiac complaint. The cumulative survival rate (excluding the period of hospitalization) was 0.87 (95% confidence interval, 0.85-0.89). Mortality varied significantly with the level of preoperative risk (i.e. the EuroSCORE), to the extent that mortality in the low-risk group was equivalent to that in the general reference population. CONCLUSIONS: Three-quarters of patients who survived until hospital discharge after coronary surgery did not experience a major cardiac event within 5 years and their level of functioning and quality of life were good. The survival rate after the immediate postoperative period varied according to the patient's preoperative risk profile and, in low-risk patients, was equivalent to that in the general reference population.

Supervivencia, estado clínico y calidad de vida a los cinco años de la cirugía coronaria. Estudio ARCA / Survival, clinical status and quality of life five years after coronary surgery. The arca study

Introducción y objetivos. El resultado tardío de la cirugía coronaria y sus determinantes son poco conocidos en España. Este estudio evalúa la evolución clínica, la calidad de vida y la supervivencia de una cohorte de pacientes, transcurridos 5 años de un primer injerto aortocoronario sin otros procedimientos asociados. Métodos. Seguimiento telefónico a los 5 años a los supervivientes de la operación, de los que se había recogido prospectivamente los datos preoperatorios y postoperatorios. Resultados. De los 1.525 pacientes dados de alta vivos, a los 5 años se obtuvo información de 1.300 (85,2%), de los que el 13,6% había fallecido y el 24% había fallecido o había sido revascularizado o ingresado por causa cardiaca. La supervivencia acumulada (excluyendo la fase hospitalaria) fue de 0,87 (intervalo de confianza [IC] del 95%, 0,85-0,89). La tasa de mortalidad fue distinta según el riesgo preoperatorio (EuroSCORE); la del grupo con bajo riesgo fue equivalente a la de la población general de referencia. Conclusiones. De cada 4 supervivientes al alta 3 están libres de eventos mayores a los 5 años, con buenas capacidad funcional y calidad de vida. La supervivencia después del postoperatorio inmediato varía en función de las características prequirúrgicas de riesgo y en el grupo con bajo riesgo es equivalente a la de la población general de referencia (AU)

[Coronary artery bypass surgery using the mini-extracorporeal circulation system: a Spanish unit's experience]. / Cirugía coronaria con mini-circulación extracorpórea: experiencia de un grupo en España.

INTRODUCTION AND OBJECTIVES: The increasing use of percutaneous interventions has resulted in a significant reduction in coronary artery bypass grafting. Today, patients referred for surgery are older, have more comorbidities, and have undergone previous percutaneous intervention, and their ventricular function is poorer. As a result, surgery has attempted to improve its results by adopting a number of different strategies. The aim of this study was to investigate and describe one cardiac surgery unit's initial experience with coronary artery bypass grafting using mini-extracorporeal circulation (MECC), which had become its technique of choice. METHODS: A retrospective analysis of 408 patients who underwent isolated coronary artery bypass grafting using MECC between January 2004 and April 2007 was carried out. Of the 408, 329 (80.6%) were men, their mean age was 63.5 years (28-83 years), 63% had hypertension, 49.3% had diabetes, 69% had hyperlipidemia, and 52% were smokers. RESULTS: The surgical mortality rate predicted by the logistic EuroSCORE was 3.7% (range, 1-38). Overall, 34% of patients had left main coronary artery disease and 87% had three-vessel disease. In 74%, complete revascularization was carried out using a mean of 2.97 (range, 1-7) grafts per patient. A mammary artery graft was used in all cases. The in-hospital mortality rate was 0.74%. There were few postoperative complications: 0.98% of patients required further surgery because of bleeding, 3.4% had a significantly elevated troponin-I level, 6.4% developed kidney failure, and 0.5% suffered a stroke. CONCLUSIONS: Coronary artery bypass grafting using MECC enabled complete revascularization to be performed in most patients, and morbidity and mortality rates were low.

Cirugía coronaria con mini-circulación extracorpórea: experiencia de un grupo en España / Coronary Artery Bypass Surgery Using the Mini-Extracorporeal Circulation System: A Spanish Unit's Experience

Introducción y objetivos. El incremento del intervencionismo percutáneo ha conllevado una disminución significativa de la cirugía coronaria. El perfil del paciente coronario que se remite a cirugía es más añoso, con mayor comorbilidad, peor función ventricular y con procedimientos percutáneos previos. En este sentido la cirugía ha intentado mejorar sus resultados desde varios frentes de actuación. El objetivo es analizar y describir la experiencia inicial de la cirugía coronaria con mini-circulación extracorpórea (MCEC) en un grupo de cirugía cardiaca en el que se ha convertido en técnica de elección. Métodos. Entre enero de 2004 y abril de 2007, se analizó de forma retrospectiva a 408 pacientes sometidos a cirugía coronaria aislada con MCEC, 329 (80,6%) varones, con media (intervalo) de edad de 63,5 (28-83) años. Un 63% tenía hipertensión; el 49,3%, diabetes; el 69%, dislipemia, y el 52% eran fumadores. Resultados. El EuroSCORE logístico (mortalidad esperada) era del 3,7% (1%-38%). El 34% de los pacientes tenían afección del tronco común y el 87%, enfermedad de 3 vasos. En el 74% de los casos se realizó revascularización completa, con un número medio de injertos de 2,97 (1-7). Se utilizó injerto de mamaria en el 100% de los casos. La mortalidad hospitalaria fue del 0,74%. Las complicaciones postoperatorias fueron pocas: el 0,98% precisó reintervención por sangrado, en el 3,4% se elevó la troponina I de forma significativa, en el 6,4% se desarrolló insuficiencia renal y el 0,5% tuvo accidente vascular cerebral. Conclusiones. La cirugía coronaria con MCEC permite realizar una revascularización completa en la mayoría de los pacientes, con buenos resultados de morbimortalidad (AU)
