Background: Penetrating cardiac injury (PCI) is a rare injury with high morbidity and mortality. Aim: To analyze the evolution of clinical and anatomical characteristics, severity, morbidity and mortality of patients operated on by PCI. Materials and Methods: Analytical study of patients surgically treated for PCI at the "Guillermo Grant Benavente" Regional Clinical Hospital, Concepción, Chile. Two periods were analyzed: January-1990 to December-2004 and January-2005 to December-2019. Sex, age, associated injuries, trauma agent and mechanism, pathophysiological behavior, anatomic location of the injury, classifications of cardiac trauma: Attar, Saadia and OIS-AAST, TSI (trauma severity indices): ISS, RTS-T and TRISS, morbidity and mortality were compared according to periods. Statistical analysis was performed with SPSS25®, the chi-square, Fisher exact and Mann-Whitney tests were used. A p value < 0.05 was considered significant. Results: Total 235 PCI, 112 in the first period and 123 in the second. Stab as mechanism in 96 (85.7%) and 104 (84.6%) according to periods. An increase in associated extra thoracic injuries, cardiorespiratory arrest, and injury to the left location were observed in the second period. The cardiac trauma classifications and the TSI ISS, RTS-T and TRISS showed greater severity and probability of death in the second period patients. Mortality did not show differences: 14 (12.5%) and 14 (11.4%) according to periods, p = 0.792. Discussion: In our series, patients treated with PCI have evolved towards a more severity profile in both, physiological and anatomical parameters. Mortality has been stable over time.

Ruptura traumática de músculo papilar da valva tricúspide com forame oval patente adquirido e ruptura atrial direita oculta / Traumatic tricuspid valve papillary muscle case with concomitant acquired patent foramen ovale and covert right atrial rupture

RESUMO O traumatismo cardíaco é comum em acidentes com veículos automotores. Uma mulher com 50 anos de idade foi transportada para nosso hospital após sofrer múltiplos traumatismos em um acidente de automóvel quando dirigia em alta velocidade. Após admissão à unidade de terapia intensiva, uma ultrassonografia cardíaca revelou ruptura traumática de músculo papilar da valva tricúspide e forame oval patente, enquanto se observou, no exame físico, o sinal de Lancisi. Foi realizado tratamento cirúrgico com anuloplastia da valva e fechamento do forame oval patente; durante o ato cirúrgico, diagnosticou-se ruptura oculta do átrio direito.

ABSTRACT Cardiac trauma often occurs in motor vehicle accidents. A 50-year-old female driver was transported to our hospital with multiple trauma after a high-speed car accident. After admission to the intensive care unit, cardiac ultrasound examination revealed traumatic tricuspid valve papillary muscle rupture and patent foramen ovale, while Lancisi's sign was noted on physical examination. Surgical treatment was performed with valve annuloplasty and closure of the patent foramen ovale and a covert right atrial defect that was detected intraoperatively.

Long-term traumatic and asymptomatic aorto-right atrial fistula

Abstract Aorto-atrial fistulas due to cardiac trauma are rare, and survivors require immediate surgical correction. Here, we report a case of an aorto-right atrial fistula due to penetrating trauma after a 16-year evolution, which developed symptoms of acute coronary syndrome and was treated with myocardial revascularization and correction of the aorto-cameral fistula.

Erosión muy tardía de la aurícula derecha con dispositivo Amplatzer®; reporte de un caso / Very late erosion of the right atrium with Amplatzer® device

Resumen La erosión tardía de la pared auricular y de la aorta es una causa infrecuente, pero potencialmente mortal en los pacientes que han sido sometidos al cierre percutáneo de un defecto del septum auricular, en especial cuando existe una alta relación entre el tamaño del dispositivo escogido con el tamaño del defecto y la presencia de bordes insuficientes. Presentamos el caso de un hombre de 70 años con un episodio de colapso hemodinámico secundario a taponamiento cardiaco debido a erosión muy tardía de la aurícula derecha por un Amplatzer® implantado 4 años atrás para el cierre de un defecto septal auricular. Conclusión La erosión tardía de los dispositivos de cierre percutáneo para los defectos atriales, aunque infrecuente, deberá ser tenida en cuenta en los pacientes que presentan colapso hemodinámico.

Abstract Late atrial wall and aorta erosion is a rare cause of potential fatallity in patients who have undergone percutaneous closure of an atrial septal defect, especially when a high ratio device to defect is chosen, and an insufficient aortic rim is present. We report the case of a 70 year old male with an episode of hemodinamic collapse secondary to cardiac tamponade due to a late erosion of a 4 years ago implanted Amplatzer® used to close an atrial septal defect. Conclusion Very late wall erosion of an atrial septal closure device, although uncommon, should be suspected in patients presenting with hemodynamic collapse.

Intracardiac embolization of inferior vena cava filter associated with right atrium perforation and cardiac tamponade / Embolização de filtro de veia cava associado à perfuração de átrio direito e tamponamento cardíaco

Insertion of inferior vena cava filters has been well established in literature, reducing occurrence of pulmonary embolism after an episode of deep venous thrombosis in patients with contraindication to anticoagulation. There are a small number of complications related to procedure and embolization is rare. In this context, we described a case of intracardiac embolization associated with cardiac tamponade.

A colocação percutânea de filtro de veia cava inferior é bem estabelecida em literatura, reduzindo a chance de ocorrência de tromboembolismo pulmonar após um episódio de trombose venosa profunda em pacientes com contraindicações à anticoagulação. O índice de complicações relacionadas ao procedimento é pequeno, sendo embolização evento extremamente raro. Nesse contexto, descrevemos um caso de embolização intracardíaca de filtro de veia cava inferior associada ao tamponamento cardíaco.

What is behind radiofrequency delivery at the cavo-tricuspid isthmus? / ¿Qué sucede en el istmo cavo-tricuspídeo durante la ablación con radiofrecuencia?

Catheter-based ablation of isthmus-dependent common atrial flutter results in very high success rates and almost no complications. However, bidirectional conduction block through the isthmus may be challenging in a small percentage of patients regarding the use of high power and high temperature settings during radiofrequency delivery. Anatomical and physiological circumstances may be the reason for such difficulties to achieve bidirectional block at the cavo-tricuspid isthmus. However, in the present case we show edema formation after multiple shots of radiofrequency delivery at the cavo-tricuspid isthmus, which complicates the achievement of bidirectional conduction block.

La ablación con catéter del flutter de tipo común dependiente del istmo es un procedimiento con elevada tasa de éxito y rara vez complicaciones. Sin embargo, en un pequeño porcentaje de casos puede resultar complicado conseguir el objetivo de bloquear bidireccionalmente el istmo durante el procedimiento de ablación a pesar de incrementar la potencia y temperatura del catéter de radiofrecuencia. Las características anatómicas y fisiológicas del istmo cavo-tricuspídeo pueden ocasionar dificultades en la consecución del bloqueo bidireccional. Sin embargo, en el presente caso mostramos cómo la propia aplicación de radiofrecuencia puede ocasionar edema importante tras múltiples aplicaciones con las consiguientes dificultades para conseguir el bloqueo bidireccional del istmo.

Emergent cardiopulmonary bypass during pectus excavatum repair.

Pectus excavatum is a chest wall deformity that produces significant cardiopulmonary disability and is typically seen in younger patients. Minimally invasive repair of pectus excavatum or Nuss procedure has become a widely accepted technique for adult and pediatric patients. Although it is carried out through a thoracoscopic approach, the procedure is associated with a number of potential intraoperative and post-operative complications. We present a case of cardiac perforation requiring emergent cardiopulmonary bypass in a 29-year-old male with Marfan syndrome and previous mitral valve repair undergoing a Nuss procedure for pectus excavatum. This case illustrates the importance of vigilance and preparation by the surgeons, anesthesia providers as well as the institution to be prepared with resources to handle the possible complications. This includes available cardiac surgical backup, perfusionist support and adequate blood product availability.

Isolated tear in left atrial appendage due to blunt trauma chest: a rare case report

Blunt traumatic cardiac rupture is associated with a high mortality rate. Motor vehicle accidents account for most cardiac ruptures, but crush injury is relatively rare. We describe a case of a 72-year-old man who had the left atrial appendage ruptured through blunt trauma due to a fall from scooter. Simple suture repair of the atrial appendage was achieved after clamping the base of the left atrium to control the bleeding. He recovered without complication. Traumatic injury to left atrial appendage is rarely seen and reported

Índice de volume do átrio esquerdo é um preditor independente de morte por causa cardiovascular no primeiro ano de tratamento com hemodiálise / Left atrial volume index is an independent predictor of cardiovascular mortality in the first year of hemodialysis

Introdução: O índice de volume do átrio esquerdo (IVAE) é um preditor independente para eventos cardiovasculares (CV), em pacientes que fazem hemodiálise (HD), há mais de 01 ano. Entretanto, a mortalidade desses pacientes é maior no primeiro ano de tratamento com HD. Objetivo: Avaliar o valor prognóstico do IVAE, como preditor de morte por causa CV, nos pacientes com IRC, dentro do primeiro ano de tratamento com HD. Métodos: Estudo prospectivo e observacional, incluindo pacientes com IRC e indicação imediata para iniciar tratamento do HD. Os participantes foram acompanhados durante 01 ano: 03 sessões de hemodiálise por semana, com 04 horas/sessão. Todos realizaram um ecocardiograma, até 24 horas após a primeira sessão de hemodiálise. Resultados: Foram incluídos 50 pacientes com média de 55 anos (18-94), sendo 30 (60%) homens. Houve 09 (18%) mortes por causa CV. O IVAE, antes de começar HD, era 38,2 +- 10,2ml/m2, sendo 47,7 +- 6,2ml/m2 nos pacientes que morreram por causa CV e 36,2 +- 9,8ml/m2, naqueles sem o desfecho preconizado (p valor=0,002). A curva ROC mostrou IVAE=37,5ml/m2, como o melhor ponto de corte para predição de morte CV (área abaixo da curva=0,85). Não houve morte por causa CV entre os 26 participantes que apresentavam IVAE<37,5ml/m2 antes de iniciar HD. Dos 24 pacientes com IVAE...

Criss-cross con concordancia aurícular-ventricular y discordancia ventrículo-arterial: presentación clínica / Criss-cross with atrioventricular concordance and ventriculoarterial discordance: clinical presentation

El corazón con entrecruzamiento de la circulación venosa pulmonar y sistémica a nivel auriculoventricular, denominada criss-cross, puede coexistir en presencia de situs solitus o situs inversus con concordancia o discordancia aurículo-ventricular dependiendo de la rotación cardíaca sobre el eje longitudinal ventricular, a favor o en contra de las manecillas del reloj. Presentamos el caso clínico de un lactante menor masculino con diagnóstico de corazón en criss-cross con concordancia aurículo-ventricular y discordancia ventrículo-arterial que ingresó a nuestro centro con disnea y cianosis. En un primer abordaje se le practica atrioseptostomía quirúrgica, sin embargo, en su evolución intrahospitalaria presenta falla cardíaca global refractaria a tratamiento convencional, por lo cual es llevado a nuevamente a cirugía donde se le realiza intervención de Damus-Kaye-Stansel. En el presente artículo se analizan los detalles de la evaluación ecocardiográfica, el cateterismo cardíaco, la resonancia magnética cardíaca y se plantean las opciones quirúrgicas de esta fascinante entidad patológica.

A heart with cross circulation (criss – cross) can coexist in the presence of situs solitus or situs inversus, with atrioventricular concordance or discordance, depending on the cardiac rotation over the ventricular longitudinal axis, clockwise or clock counterwise. This is the presentation of the clinical case of a male lactant, with diagnosis of criss–cross heart with atrioventricular concordance and ventriculoarterial discordance, who was admitted to these facilities with dyspnoea and cyanosis. In a first approach, a surgical atrioseptectomy was performed on the patient. However, in his intrahospitalary evolution, the patient had a global heart failure refractory to conventional treatment, causing his admission into the operating room for surgery, where the Damus–Kaye–Stensel procedure was performed on him. This article presents an analysis of the details of the echocardiographic evaluation, the cardiac catheterization, and the cardiac magnetic resonance of the clinical case, raising the surgical options for this fascinating pathological entity.

Device-induced perforation of right atrium following interventional closure of atrial septal defect [ASD]

This is a case presentation of a 26-year-old woman with a moderate-sized atrial septal secundum defect [17mm] who underwent catheterism, during which an Amplatzer Septal Occluder number 26 was inserted successfully. On the second postoperative day, she deteriorated and a clinical examination showed a typical tamponade. After a percutaneous aspiration of the pericardial cavity and transient improvement in vital signs, a pig-tail catheter was inserted percutaneously emergently, and the patient was transferred to the operating room in a preshock state. During the operation, an active bleeding point in the superoanterior aspect of the right atrium near the aortic root was detected, which was repaired by direct suture and pericardial patch reinforcement. The Amplatzer device was removed and the atrial septal defect was repaired with a pericardial patch. A lethal complication of the interventional closure of atrial septal defect, properly treated by an emergent intervention and operation, is presented and discussed herein

Perforación tricuspídea traumática: presentación de un caso / Traumatic tricuspid valve perforation: case report

Esta comunicación describe el caso de un paciente que ingresa en la guardia del hospital con una herida de arma de fuego a nivel precordial, en paro cardiorrespiratorio. La lesión interesó el ventrículo derecho, la aurícula derecha y el pulmón derecho. Dichos daños se repararon quirúrgicamente por cardiorrafia y drenaje del hemotórax derecho. El ecocardiograma en el posoperatorio mediato descubrió una perforación de una valva de la tricúspide, que produjo insuficiencia tricuspídea leve. Se realizan diferentes consideraciones referentes a los traumatismos cardíacos

Ruptura de aurícula derecha por traumatismo toracoabdominal no penetrante / Rigth atrial rupture following blunt thoracoabdominal injury

Se presenta una niña de 5 años que sufrió un traumatismo no penetrante, por la caída de una pileta de lavar sobre su región toracoabdominal. Tenía lesiones múltiples, siendo la más importante, por su compromiso vital, la ruptura de la aurícula derecha (AD). Se analizan los hallazgos clínicos y quirúrgicos, haciéndose hicapié en los mecanismos que obraron para producir la disrupción auricular. Las lesiones abdominales y la cuestionable laparotomía exploradora exceden los límites del presente análisis

Effect of atrial septal defect created during balloon mitral valvuloplasty on calculation of cardiac output and mitral valve area.

We studied the effect of atrial septal defect (ASD), produced during transseptal puncture, on estimation of cardiac output (CO) and mitral valve area (MVA), after successful balloon mitral valvuloplasty (BMV) using the Inoue balloon in 20 patients. Oximetry run, pressure gradients, thermodilution CO and MVA were measured initially while temporarily occluding the ASD by partially inflating the Inoue balloon catheter. Measurements were repeated after withdrawing the balloon catheter into the right atrium. Post-BMV cardiac output and MVA were similar in both the situations (4.52 +/- 1.37 L/min vs 4.50 +/- 1.19 L/min; 1.89 +/- 0.4 cm2 vs 1.93 +/- 0.38 cm2 respectively, p = ns). Only 2 patients showed a step up at atrial level on oximetry (9% and 16% respectively) but did not have significantly different CO or MVA, both with ASD occluded or otherwise. We conclude that the magnitude of ASD created during BMV by Inoue balloon technique is small and does not significantly affect the estimation of CO or MVA if the septal puncture is done in the fossa ovalis area.

Rotura do átrio direito por traumatismo fechado: relato de caso operado com sucesso / Right atrial rupture by closed traumatism: report of a case operated with success

Paciente de 30 anos, com história de acidente automobilístico há 2 horas. Apresentava, ao exame físico, sinais de tamponamento cardíaco. A radiografia de tórax revelava aumento da área cardíaca e à radioscopia, havia imagem compatível com tamponamento. Indicada cirurgia, foi realizada esternotomia mediana devido à imagem radiológica e à ausência de derrame pleural bilateralmente. Havia fratura total do esterno na sua porçäo média, importante hemopericárdio e uma lesäo de átrio direito na base da aurícula, provavelmente causada pela báscula do esterno, além de pequeno orifício na aorta. Realizado pinçamento lateral na base do átrio direito, foi ressecada a área macerada e feita secçäo da aurícula, separando-se a parede anterior da posterior, tornando-a única. Tornou-se assim possível a correçäo da lesäo com a própria parede auricular, rebatendo-se essa parede sobre a área ressecada. Na aorta foi realizada sutura direita. O paciente evoluiu bem, estando assintomático no 15§ mês de pós-operatório
