RESUMO

BACKGROUND: Although pre-surgical nasal decontamination with mupirocin (NDM) has been advocated as a measure for preventing post-surgical mediastinitis (PSM) due to Staphylococcus aureus, this strategy is not universally recommended due to the lack of robust supporting evidence. We aimed to evaluate the role of pre-operative NDM in the annual incidence of S. aureus PSM at our institution. METHODS: An interrupted time-series analysis, with autoregressive error model, was applied to our single-center cohort by comparing pre-intervention (1990-2003) and post-intervention period (2005 to 2018). Logistic regression was performed to analyze risk factors for S. aureus PSM. FINDINGS: 12,236 sternotomy procedures were analyzed (6,370 [52.1%] and 5,866 [47.9%] in the pre-intervention and post-intervention periods, respectively). The mean annual percentage adherence to NDM estimated over the post-interventional period was 90.2%. Only four out of 127 total cases of S. aureus PSM occurred during the 14-years post-intervention period (0.68/1,000 sternotomies vs. 19.31/1,000 in pre-interventional period [p<0.0001]). Interrupted time-series analysis demonstrated a statistically significant annual reduction of S. aureus PSM trend of -9.85 cases per 1,000 sternotomies (-13.17 to -6.5, P-value< 0·0001) in 2005, with a decreasing trend maintained over the following five years with an estimated relative reduction of 84.8% (95% CI: 89·25 to 74·09). Chronic obstructive pulmonary disease was the single independent risk factor for S. aureus PSM (odds ratio: 3.7; 95% CI: 1.72-7.93) and was equally distributed in patients undergoing sternotomy during pre or post-intervention periods. INTERPRETATION: Our experience suggests that the implementation of pre-operative NDM reduces significantly the incidence of S. aureus PSM.

RESUMO

This study aimed to evaluate the feasibility of a noninvasive operability assessment of chronic thromboembolic pulmonary hypertension (CTEPH) based on multidetector computed tomographic angiography (MCTA). Up to 176 patients were evaluated from January 2016 to April 2018. Throughout the first phase, the initial surgical decision was made based on MCTA with further analysis of pulmonary angiography (PA) in order to evaluate in which cases the initial decision was not modified by PA. During the second phase, PA was limited to patients judged inoperable based on MCTA or those whose assessment was not possible. Patients deemed operable (50%) based on MCTA along the first phase had been adequately classified, as PA did not modify the initial decision in all but one patient. Comparable results were obtained throughout the implementation phase. Regarding operated patients, the decision of operability was based solely on MCTA in 94% of those with level I disease, in 75% with level II, and 54% with level III. This approach enabled shorter periods of time to complete surgical assessment and the avoidance of PA-related morbidity. Baseline parameters, postoperative measures, and survival rates at 1 year after surgery were comparable in both phases. Noninvasive operability assessment is feasible in a subset of CTEPH patients and optimizes surgical candidacy evaluation.

RESUMO

Resumen Se describe el caso de una mujer de 68 años que presentaba insuficiencia tricuspídea severa con ventrículo derecho dilatado, función sistólica levemente deprimida y ventrículo izquierdo no dilatado con fracción de eyección del 47%. Se intervino mediante cirugía realizándose una sustitución valvular tricúspide por prótesis mecánica ATS n( 33 e implante de electrodo de marcapasos epicárdico definitivo. En el postoperatorio inmediato presentó ascenso persistente del segmento ST en la cara inferior. Se implantó balón de contrapulsación intraaórtico y en el ecocardiograma urgente se observó disfunción ventricular global con aquinesia de la cara inferior. Se realizó coronariografía urgente observándose una imagen de angulación y deformidad a nivel distal de la arteria coronaria derecha no presente en la coronariografía prequirúrgica que sugería tracción externa del vaso, probablemente en relación con la sutura quirúrgica. Se intervino en forma percutánea implantándose stent farmacoactivo con lo cual se recuperó el flujo distal y se normalizó el segmento ST. La proximidad del anillo tricúspide a estructuras anatómicas como la arteria coronaria derecha hace posible su lesión durante la cirugía. El daño iatrogénico de la arteria coronaria derecha requiere diagnóstico y tratamiento precoz. Por ello esta complicación se debe incluir en el diagnóstico diferencial de disfunción ventricular derecha tras cirugía cardiaca.


Abstract The case is presented on a 68 year-old woman with severe tricuspid insufficiency. She also had a dilated right ventricle, a slightly depressed systolic function, and an undilated left ventricle with an ejection fraction of 47%. We treated her surgically, the tricuspid valve replacement was carried out with an ATS Nº 33 mechanical prosthesis and implanted a permanent epicardial pacemaker lead. In the immediate post operative period, she presented a persistent ST segment elevation on the inferior wall. An intra-aortic balloon pump was implanted; the urgent echocardiogram showed a global ventricular dysfunction with akinesia of the inferior wall. An urgent coronary angiography was performed, with an image of angulation and deformity being observed at distal level of the right coronary artery that was not present in the pre-surgical coronary angiography, which suggested an external traction of the vessela probably associated with a surgical suture. Percutaneous intervention was carried out, with a drug-eluting stent being implanted. It was percutaneously treated by implanting a drug-eluting stent restoring distal blood flow and normalizing the ST segment. The proximity of the tricuspid ring to anatomical structures like the right coronary artery means that it could be damaged during surgery. The iatrogenic damage to the right coronary artery requires an early diagnosis and treatment. For this reason, this complication must be included in the differential diagnosis of right ventricular dysfunction after cardiac surgery.

RESUMO

Fundamento y objetivo: La cirugía de tromboendarterectomía pulmonar es el tratamiento de elección para la hipertensión pulmonar tromboembólica crónica; un factor de riesgo para la mortalidad hospitalaria son las resistencias vasculares pulmonares muy elevadas. El objetivo de este trabajo fue analizar los resultados inmediatos y a largo plazo de la cirugía para la hipertensión pulmonar tromboembólica crónica en pacientes con hipertensión pulmonar muy grave. Material y métodos: Desde febrero de 1996 hemos realizado 160 tromboendarterectomías pulmonares. Dividimos esta población en grupo 1 -40 pacientes con resistencias vasculares pulmonares ≥ 1.090dinas/s/cm-5- y grupo 2 -los 120 restantes-. Resultados: La mortalidad hospitalaria (15 frente a 2,5%), el edema pulmonar de reperfusión (33 frente a 14%) y la insuficiencia cardiaca (23 frente a 3,3%) fueron significativamente mayores en el grupo 1; pero al año, no hay diferencia en la situación clínica, hemodinámica y ecocardiográfica con el grupo 2. La supervivencia a los 5 años fue del 77% en el grupo 1 y del 92% en el grupo 2 (p=0,033). Excluyendo los primeros 46 enfermos, considerados curva de aprendizaje, no hubo diferencia en la mortalidad hospitalaria (3,8 frente a 2,3%) ni en la supervivencia (96,2% en el grupo 1 y 96,2% en el grupo 2 a los 5 años). Conclusiones: La tromboendarterectomía pulmonar tiene una morbimortalidad inicial mayor en pacientes con hipertensión pulmonar tromboembólica crónica muy grave, pero obtiene el mismo beneficio a medio-largo plazo. En nuestra experiencia, tras la curva de aprendizaje, la cirugía ofrece la misma seguridad y excelentes resultados a los pacientes más graves, y ninguna cifra de resistencias vasculares pulmonares debería ser considerada una contraindicación absoluta (AU)


Background and objective: Pulmonary thromboendarterectomy surgery is the treatment of choice for patients with chronic thromboembolic pulmonary hypertension; extremely high pulmonary vascular resistance constitutes a risk factor for hospital mortality. The objective of this study was to analyze the immediate and long-term results of the surgical treatment of chronic thromboembolic pulmonary hypertension in patients with very severe pulmonary hypertension. Material and methods: Since February 1996, we performed 160 pulmonary thromboendarterectomies. We divided the patient population in 2 groups: group 1, which included 40 patients with pulmonary vascular resistance≥1090dyn/sec/cm-5, and group 2, which included the remaining 120 patients. Results: Hospital mortality (15 vs. 2.5%), reperfusion pulmonary edema (33 vs. 14%) and heart failure (23 vs. 3.3%) were all higher in group 1; however, after one year of follow-up, there were no significant differences in the clinical, hemodynamic and echocardiographic conditions of both groups. Survival rate after 5 years was 77% in group 1 and 92% in group 2 (P=.033). After the learning curve including the 46 first patients, there was no difference in hospital mortality (3.8 vs. 2.3%) or survival rate after 5 years (96.2% in group 1 and 96.2% in group 2). Conclusions: Pulmonary thromboendarterectomy is linked to significantly higher morbidity and mortality rates in patients with severe chronic thromboembolic pulmonary hypertension. Nevertheless, these patients benefit the same from the procedure in the mid-/long-term. In our experience, after the learning curve, this surgery is safe in severe pulmonary hypertension and no level of pulmonary vascular resistance should be an absolute counter-indication for this surgery (AU)

RESUMO

Introducción: La tromboendarterectomía pulmonar es el tratamiento de elección en la hipertensión pulmonar tromboembólica crónica. Presentamos nuestra serie completa con esta técnica. Métodos: Desde febrero de 1996 hasta junio de 2014, hemos realizado 106 tromboendarterectomías. Analizamos las características de la población, la mortalidad y morbilidad asociadas a la técnica y los resultados a largo plazo de supervivencia, mejoría funcional y resolución de la hipertensión pulmonar. Resultados: La edad media de la población fue 53 ± 14 años. El 89% estaba en clase funcional III-IV de la OMS. La presión pulmonar media prequirúrgica fue 49 ± 13 mmHg y las resistencias vasculares pulmonares 831 ± 364 dinas.s.cm-5. La mortalidad hospitalaria fue 6,6%. La morbilidad postoperatoria más relevante fue debida al edema pulmonar por reperfusión en el 20%, que fue factor de riesgo independiente (p = 0,015) para mortalidad hospitalaria. Con una mediana de seguimiento de 31 meses (rango intercuartil 50), la supervivencia a los 3 y 5 años es 90 y 84%. Al año de seguimiento, el 91% está en clase funcional I-II de la OMS, la presión pulmonar media en 27 ± 11 mmHg y las resistencias pulmonares vasculares en 275 ± 218 dinas.s.cm-5 (significativamente menores (p < 0,05) que las basales). En 14 pacientes se diagnosticó hipertensión pulmonar persistente; aun así, su supervivencia es, a los 3 y 5 años, 91 y 73%, respectivamente. Conclusiones: La tromboendarterectomía pulmonar ofrece resultados excelentes en el tratamiento de la hipertensión pulmonar tromboembólica crónica. Proporciona una elevada supervivencia a largo plazo, mejora la capacidad funcional y resuelve la hipertensión pulmonar en la mayoría de los pacientes

Methods: Between February 1996 and June 2014, we performed 106 pulmonary thromboendarterectomies. Patient population, morbidity and mortality and the long-term results of this technique (survival, functional improvement and resolution of pulmonary hypertension) are described. Results: Subjects' mean age was 53 ± 14 years. A total of 89% were WHO functional class III–IV, presurgery mean pulmonary pressure was 49 ± 13 mmHg and mean pulmonary vascular resistance was 831 ± 364 dynes s cm-5. In-hospital mortality was 6.6%. The most important post-operative morbidity was reperfusion pulmonary injury, in 20% of patients; this was an independent risk factor (P = .015) for hospital mortality. With a 31-month median follow-up (interquartile range: 50), 3- and 5-year survival was 90% and 84% respectively. At 1 year, 91% were WHO functional class I–II; mean pulmonary pressure (27 ± 11 mmHg) and pulmonary vascular resistance (275 ± 218 dynes s cm-5) were significantly lower (P < .05) than before the intervention. Although residual pulmonary hypertension was detected in 14 patients, their survival at 3 and 5 years was 91% and 73%, respectively. Conclusions: Pulmonary thromboendarterectomy offers excellent results in chronic thromboembolic pulmonary hypertension. Long-term survival is good, functional capacity improves, and pulmonary hypertension is resolved in most patients

RESUMO

Laubry-Pezzi syndrome is a clinical entity in which prolapse of an aortic valve cusp into a subjacent ventricular septal defect (VSD) due to Venturi effect results in progressive aortic valve insufficiency. Aortic valve prolapse is found in over 5% of children with VSDs, most commonly in association with supracristal VSDs, and the risk of development of aortic regurgitation increases during childhood, peaking at 5 to 10 years of age. The VSD closure eliminates the low-pressure zone that is the cause of ongoing aortic valve cusp deformity and, if performed early, prevents the development of aortic regurgitation. However, the management of this rare pathology is still a matter of some debate with respect to indications, operative techniques, and timing. We report the case of a patient with Laubry-Pezzi syndrome, originally operated on at six years of age for VSD closure and plasty between the left and the right aortic cusps. However, in the follow-up the patient developed severe aortic regurgitation and aortic root dilatation. Eventually, a Bentall and De Bono procedure was performed.

RESUMO

Introducción y objetivos. Cuando la válvula aórtica bicúspide se asocia a dilatación de la aorta, la reparación quirúrgica precisa actuar sobre todos los componentes de la raíz de aorta. Revisamos nuestra experiencia en esta cirugía. Métodos. Se realizó un estudio observacional descriptivo y retrospectivo con el objetivo de analizar la morbilidad y la mortalidad de estas técnicas y valorar la durabilidad a medio plazo de la válvula aórtica. Se incluyó a todos los pacientes con válvula aórtica bicúspide y dilatación de la aorta intervenidos en nuestro centro entre 1999 y 2011 con alguna técnica de preservación valvular. Resultados. Se intervino a 151 pacientes. En 51 se empleó alguna técnica de preservación valvular. La media de edad era 51 ± 12 años y el 92% eran varones. En el 69% la insuficiencia aórtica era menor de grado II y los velos aórticos presentaban poca degeneración estructural. En 32 pacientes se realizó reimplante valvular. No hubo mortalidad hospitalaria. Con una mediana de seguimiento de 36 [intervalo intercuartílico, 18-45] meses, ningún paciente ha fallecido o ha requerido reintervención y todos los pacientes están libres de insuficiencia aórtica mayor de grado II . Conclusiones. La cirugía de preservación de la válvula aórtica bicúspide asociada a dilatación de la aorta muestra unos resultados a corto y medio plazo excelentes en válvulas seleccionadas. La estabilización de todos los componentes de la raíz de aorta mejora la durabilidad de la válvula, y las técnicas propuestas se muestran reproducibles y estables a medio plazo (AU)


Introduction and objectives: When the bicuspid aortic valve is associated with dilatation of the aorta, surgical repair requires correction of all the components of the aortic root. Here, we review our experience in this type of surgery. Methods: A descriptive and retrospective observational study was carried out to analyze morbidity and mortality in valve-sparing techniques and evaluate the medium-term durability of the aortic valve. We included all patients with a bicuspid aortic valve and dilatation of the aorta who underwent surgery with a valve-sparing technique in our center between 1999 and 2011. Results: A total of 151 patients underwent surgery. A valve-sparing technique was used in 51 patients. The mean (standard deviation) age of the patients was 51 (12) years and 92% were men. In 69% of the patients, aortic insufficiency was less than grade II and the aortic cusps showed little structural degeneration. Valve reimplantation was performed in 32 patients. There was no hospital mortality. With a median follow-up of 36 months (interquartile range, 18-45 months), none of the patients died or required reoperation, and all patients were free of aortic insufficiency greater than grade II. Conclusions: Valve-preserving surgery in bicuspid aortic valves associated with dilatation of the aorta shows excellent short- and medium-term results in selected valves. The stabilization of all of the components of the aortic root improves the durability of the valve, and the techniques proposed are reproducible and stable in the medium-term (AU)

RESUMO

An eustachian valve (EV) remnant, if present, is usually noted by the presence of a thin ridge or a crescent-shaped fold of endocardium arising from the anterior rim of the inferior vena cava orifice due to the persistence of the right sinus venosus valve. Though the embryologic explanation of cor triatriatum dexter (CTD) is the same as that of the normal formation of the EV--lack of regression of the right sinus venosus valve--it is usually called CTD or divided right atrium when there are attachments on the atrial septum giving the appearance of a divided atrium. However, it's called prominent eustachian valve when the right sinus venosus valve has partly regressed, with no remaining septal attachments and without the appearance of a divided atrium. We present the case of an adult patient with an atrial septal defect with a high insertion of a giant EV, which mimics the echocardiographic appearance of divided right atrium.

RESUMO

BACKGROUND: Pulmonary artery aneurysms are a rare condition, frequently associated with pulmonary hypertension. However, the evolution and treatment of this pathology is still not clear. CASE PRESENTATION: The authors report a case of a 65-year old patient with pulmonary artery aneurysm associated with pulmonary arterial hypertension. Due to a positive vasoreactivity test, treatment with calcium channel blockers was started with near normalization of the right cardiac pressures. Nevertheless, after 20 months of treatment, the pulmonary artery aneurysm size remained unchanged with an associated severe pulmonary regurgitation and causing extrinsic compression of the main left coronary artery. Surgical correction was successfully performed. CONCLUSIONS: This is the first case report of a pulmonary artery aneurysm described to be associated with vasoreactive pulmonary hypertension in a living patient. Although medical therapy for pulmonary hypertension was started, surgical correction of the aneurysm was executed in order to prevent its future complications.
