Transplantation in Congenital Heart Disease: A Challenge.

BACKGROUND: Heart failure is the leading cause of death in grown-up congenital heart disease patients (GUCH). Although heart transplantation (OHT) remains the gold standard in end-stage heart failure, the ratio of GUCH patients undergoing this procedure remains low. OBJECTIVE: Describe the cohort of GUCH patients undergoing heart transplantation at a third-level hospital. METHODS: A retrospective review of GUCH patients undergoing OHT between 1997 and 2019 was conducted at a single tertiary university hospital. We included different preoperative (demographic and clinical data, cardiac catheterization data from the last routine hemodynamic monitoring) and postoperative variables (complications, survival). RESULTS: Fourteen patients were enrolled. The median age was 25.5 years (range, 20.7-32.2). Eight patients (57.1%) were male. The median preoperative left ventricular ejection fraction was 37% (range, 22.5%-55%). As for preoperative hemodynamic evaluation, the median for the mean arterial pulmonary pressure was 19 mm Hg (range, 12-22.5), for the capillary wedge pressure was 16 mm Hg (range, 13.5-19.5), and for pulmonary vascular resistance was 1.83 Wood units (range, 1-4). After OHT, 6 patients (42.9%) suffered an infection, the most common of which was respiratory (3 out of 6). Four patients (28.6%) needed renal replacement therapy, and 4 patients (28.6%) presented liver failure. Four patients (28.6%) developed graft failure, thus requiring mechanical support with extracorporeal membrane oxygenation during a median of 6 days (range, 1-17.5). Survival rate of patients under extracorporeal membrane oxygenation was 50%, and overall survival rate was 78.6%. CONCLUSION: OHT represents a good option for GUCH patients, with good overall survival rates.

Prolonged Mechanical Ventilation as a Predictor of Mortality After Cardiac Surgery.

BACKGROUND: Mortality among the small percentage of cardiac surgery patients receiving prolonged mechanical ventilation is high, but this issue appears to be inadequately addressed in guidelines. METHODS: This study is a retrospective analysis of prospective, multi-center, and observational study in Spain including all adults undergoing cardiac surgery in 3 Andalusian hospitals between June 2008 and December 2012. RESULTS: The study included 3,588 adults with mean ± SD age of 63.5 ± 12.8 y and with median (interquartile range) EuroSCORE of 5 (3-7) points. Prolonged mechanical ventilation (> 24 h) was required by 415 subjects (11.6%), with ICU mortality of 44.3% (184 subjects), and was not required by 3,173 subjects (88.4%), with ICU mortality of 3.1% (99 subjects, P < .001). Prolonged mechanical ventilation was associated with more complications and was required by 4.5% of subjects with a EuroSCORE <5, 11.2% with a score of 5-7, 27.2% with a score of 8-10, and 32.2% with a score > 10. In the multivariable analysis, ICU mortality was associated with illness severity, duration of bypass surgery, surgery type, and prolonged mechanical ventilation (odds ratio 15.19, 95% CI 11.56-22.09). The main cause of death was multiple organ failure and sepsis in subjects who required prolonged mechanical ventilation (50.3%) and cardiogenic shock in those who did not (59.2%). CONCLUSION: Prolonged postoperative mechanical ventilation was required by 10-20% of cardiac surgery subjects, who constitute a specific group that represents most of the postoperative mortality, which is associated with multiple organ failure and sepsis.

Consecuencias de la obesidad en los resultados de la cirugía cardiaca. Análisis del registro ARIAM / Consequences of obesity in outcomes after cardiac surgery. Analysis of ARIAM registry

Fundamento y objetivo: La obesidad puede acompañarse de peores resultados tras cirugía cardiaca. Nuestro objetivo es evaluar las consecuencias de la obesidad en relación con la aparición de complicaciones postoperatorias, la estancia y la mortalidad. Método: Estudio observacional, prospectivo y multicéntrico de pacientes recogidos en el registro ARIAM de cirugía cardiaca de adultos entre marzo de 2008 y marzo de 2011. Se han analizado variables clínicas, del acto quirúrgico, complicaciones postoperatorias y mortalidad, comparando los grupos de pacientes con índice de masa corporal (IMC) mayor o menor de 30 kg/m2. Resultados: El estudio incluye 4.172 pacientes con una edad media (DE) de 64,03 (12,08) años, IMC de 28,53 (4,7) kg/m2 y EuroSCORE de 5,58 (2,91). En 1.490 pacientes (35,7%) el IMC fue mayor de 30 kg/m2. No se encontraron diferencias en el desarrollo de complicaciones posquirúrgicas globales (33% en obesos y 35,8% en no obesos, p = 0,07). Los pacientes obesos mostraron menor necesidad de reintervención quirúrgica y menor incidencia de accidente cerebrovascular en el postoperatorio (p < 0,05). Sin embargo, sí presentaron significativamente mayor deterioro de la función renal (p = 0,009). La estancia en la Unidad de Cuidados Intensivos (UCI) fue similar en ambos grupos, mientras que en planta fue mayor en los obesos, 9,04 (10,43) frente a 8,18 (9,2) días (p = 0,01). Tras ajustar por gravedad y tiempo de circulación extracorpórea, los obesos presentaron una mortalidad inferior, sin llegar a ser estadísticamente significativa (odds ratio 0,94, intervalo de confianza del 95% 0,79-1,04). Conclusiones: Los enfermos obesos sometidos a cirugía cardiaca presentan una mortalidad, complicaciones y estancia similares a las de los no obesos. Estos pacientes son reintervenidos con menos frecuencia, aunque es más habitual el desarrollo de fracaso renal agudo en el postoperatorio (AU)

Background and objective: Obesity is a disease that affects a large part of the population and has been associated with worse outcomes after cardiac surgery. The aim of our study is to evaluate the consequences of obesity related to postoperative complications, hospital length of stay and mortality. Methods: Observational, prospective, multicenter study of patients included in ARIAM registry of adult cardiac surgery between March 2008 to March 2011. We analyzed clinical variables, the surgical procedure, postoperative complications and mortality, comparing the group of patients with body mass index (BMI) greater or less than 30 kg/m2. Results: The study included 4,172 patients with a mean age of 64.03 (SD 12.08) years, BMI 28.53 (4.7) and EuroSCORE 5.58 (2.91). In 1,490 patients (35.7%) BMI was greater than 30. There were no differences in the development of overall postoperative complications (33% in obese and non-obese 35.8%,P = .07), although there were less appreciated reoperation rate or stroke (P < .05), as well as further development postoperative renal failure (P = .009). After adjusting for severity and length of cardio by pass time, obese patients had lower mortality without being statistically significant. OR 0.94 (0.79-1.04). There were no differences in ICU length of stay, but obese patients had greater Ward length of stay 9.04 (10.43) vs. 8.18 (9.2) days, P = .01. Conclusions: Obese patients undergoing cardiac surgery have a mortality, rate of complications and length of stay similar to non-obese. Obese patients required less reoperations but developed more frequently postoperative renal failure (AU)
