Background-Preoperative factors associated with increased mortality and worse outcome after tricuspid valve replacement in patients with severe tricuspid regurgitation are poorly understood. Methods and Results-We retrospectively analyzed 189 patients (37% men; age, 67.5Ϯ11.3 years) who underwent tricuspid valve replacement for severe tricuspid regurgitation. Operative mortality rate was 10%, and was associated with intra-aortic balloon pump (odds ratio, 3.2; 95% confidence interval, 1.9 to 5.6; PϽ0.0001) or the presence of severe symptoms (New York Heart Association class IV relative to classes II and/or III) at the time of surgery (1.7; 95% confidence interval, 1.05 to 2.8; Pϭ0.02). At the end of follow-up (29.3Ϯ27.1 months), 70 patients (37%) died, 6 (3%) needed tricuspid reoperation, and 41 (21.7%) were readmitted for heart failure. Seventy-eight patients (41.3%) were free from cardiovascular events (death, tricuspid reoperation, or heart failure admissions). The only echocardiographic parameter independently associated with adverse outcomes was a decrease in the right index of myocardial performance ratio. All-cause mortality was independently associated with a higher Charlson index (hazard ratio, 1.18; 95% confidence interval, 1.01 to 1.36; Pϭ0.03), shorter right index of myocardial performance ratio (0.91; 95% confidence interval, 0.87 to 0.96; Pϭ0.005), and preoperative New York Heart Association IV class (1.71; 95% confidence interval, 1.3 to 2.2; PϽ0.0001). In 68 patients with isolated tricuspid valve replacement, the associations between short right index of myocardial performance ratio, high Charlson index, New York Heart Association class IV, and increased mortality remained significant. Conclusions-Tricuspid valve replacement for severe tricuspid regurgitation can be performed with an acceptable operative mortality if patients undergo surgery before the onset of advanced heart failure symptoms. Late mortality is associated with a high preoperative Charlson index, short right index of myocardial performance ratio, and advanced
We report herein a case of benign cardiac schwannoma in the interatrial septum. A 42-year-old woman was transferred from a clinic because of cardiomegaly as determined by chest X-ray. A transthoracic echocardiography and chest computed tomography examination revealed a huge mass in the pericardium compressing the right atrium, superior vena cava (SVC), left atrium, and superior pulmonary vein. To confirm that the tumor originated from either heart or mediastinum, cine magnetic resonance imaging was performed, but the result was not conclusive. To facilitate surgical planning, we used 3D printing. Using a printed heart model, we decided that tumor resection under cardiopulmonary bypass (CPB) through sternotomy would be technically feasible. At surgery, a huge tumor in the interatrial septum was confirmed. By incision on the atrial roof between the aorta and SVC, tumor enucleation was performed successfully under CPB. Pathology revealed benign schwannoma. The patient was discharged without complication. 3D printing of the heart and tumor was found to be helpful when deciding optimal surgical approach.
Prognostic/epidemiologic study, level IV.
Intravenous immunoglobulin (IVIG) administered in the acute stage of Kawasaki disease (KD) is the standard therapy. Few reports describe nonresponders to initial treatment with IVIG in KD, which remains the most consistent risk factor for coronary artery lesions (CALs). This study aimed to investigate whether the serum level of N-terminal pro-brain natriuretic peptide (NT-proBNP) can be a predictive indicator for identifying patients with KD at higher risk of IVIG treatment failure. In this study, 135 patients with a diagnosis of KD admitted for IVIG treatment were retrospectively enrolled for analysis. Of these 135 patients, 22 were nonresponders who received additional rescue therapy because they had an elevated body temperature 36 h after completion of initial IVIG treatment. The NT-proBNP concentration was significantly higher in the nonresponder group (2,465.36 ± 3,293.24 pg/mL) than in the responder group (942.38 ± 1,293.48 pg/mL) (p < 0.05). The optimal sensitivity and specificity cutoff point for predicted nonresponders was 1,093.00 pg/mL or higher. The sensitivity and specificity for prediction of IVIG response were respectively 70.0 and 76.5 %. The findings show that NT-proBNP is a helpful marker in determining patients at risk for not responding to initial IVIG treatment. The authors suggest that patients with an NT-proBNP level of 1,093.00 pg/dL or higher are likely to fail initial IVIG and may require further rescue therapy.
Purpose: Trauma is the top cause of death in people under 45 years of age. Deaths from severe trauma can have a negative economic impact due to the loss of people belonging to socio-economically active age groups. Therefore, efforts to reduce the mortality rate of trauma patients are essential. The purpose of this study was to investigate preventable mortality in trauma patients and to identify factors and healthcare-related challenges affecting mortality. Ultimately, these findings will help to improve the quality of trauma care. methods: We analyzed the deaths of 411 severe trauma patients who presented to Gachon University Gil Hospital regional trauma center in South Korea from January 2015 to December 2017, using an expert panel review. results: The preventable death rate of trauma patients treated at the Gachon University Gil Hospital regional trauma center was 8%. Of these, definitely preventable deaths comprised 0.5% and potentially preventable deaths 7.5%. The leading cause of death in trauma patients was traumatic brain injury. Treatment errors most commonly occurred in the intensive care unit (ICU). The most frequent management error was delayed treatment of bleeding. Conclusions: Most errors in the treatment of trauma patients occurred in early stages of the treatment process and in the ICU. By identifying the main causes of preventable death and errors during the course of treatment, our research will help to reduce the preventable death rate. Appropriate trauma care systems and ongoing education are also needed to reduce preventable deaths from trauma.
Purpose: We aimed to evaluate the trauma volume and performance indicators during the first 5-year period of operation in a single regional trauma center. methods: We analyzed prospectively collected data from the Korean Trauma Data Bank for a single regional trauma center between January 2014 and December 2018. More than 250 variables were analyzed. We calculated the predicted survival rates using the trauma and injury severity score (TRISS) method. results: In total, there were 16,103 trauma admissions during the first 5 years; trauma activation was performed in 5,105 of these cases. Over 70% of the patients were men, and most of the admitted patients were within the age groups of 55-59 years for men and 75-79 years for women. Analyses were performed considering two patient groups: the total patient group and the group of those with severe trauma (injury severity score [ISS] >15). The median ISS, revised trauma score, and TRISS of the two groups were 5 (interquartile range [IQR] 4-10), 22 (IQR 17-27), and 7.6±0.99 and 6.74±1.9, 0.95±0.13, 0.81±2.67, respectively. Of the total patient group, 801 patients (5%) died in the hospital, whereas of the group of patients with ISS >15, 526 (19.5%) died. The direct transportation of patients to the regional trauma center increased year by year. The emergency room stay time and time to entering the operating room showed a decrease until 2017; however, these parameters increased again in 2018. Conclusions: The trauma volume in the regional trauma center is appropriate, and some improvements could be observed after its establishment. However, performance indicators reveal the prematurity of the trauma center and its potential for further improvements. Moreover, the development of a national trauma system, beyond regional trauma centers, is required.
IntroductionPrimary cardiac cancer is a very rare disease, among which primary cardiac angiosarcoma is one of the most frequent type and is characterized by extremely poor prognosis without established optimal treatment.Case descriptionHere we report a case of primary cardiac angiosarcoma with hemorrhagic pericardial effusion who achieved a durable response with tumor excision followed by concurrent chemoradiotherapy with docetaxel. A sixty year old man was presented with dyspnea and was diagnosed with primary cardiac angiosarcoma with hemorrhagic pericardial effusion. After surgical excision of primary tumor with microscopic residual disease followed by concurrent chemoradiotherapy with docetaxel, the patient showed durable response of progression free survival of 12 months.Discussion and evaluationThis case shows benefit of concurrent chemoradiotherapy with taxane. Further investigation of aggressive multimodal treatment strategy is warranted for primary cardiac angiosarcoma with pauci-metastasis even when achievement of complete resection seems unlikely.
BackgroundTotal arch replacement (TAR) is being more widely performed due to recent advances in operative techniques and cerebral protective strategies. In this study, the authors reviewed the relationship between TAR and early- and mid-term changes of the false lumen after TAR in acute type A aortic dissection.Materials and MethodsTwenty-six patients (aged, 54.7±13.3 years) who underwent TAR for acute type A dissection between June 2004 and February 2012 were reviewed. The relationship between the percentage change in the aortic diameter and the false lumen patency status was assessed by examining the early and late postoperative computed tomography imaging studies.ResultsThere were two in-hospital mortalities, one late death, and three follow-up loses. The mean follow-up duration for the final 21 patients studied was 54±19.0 months (range, 20 to 82 months). The incidence of false lumen thrombosis within 2 weeks of surgery in the proximal, middle, and distal thoracic aorta, and the suprarenal and infrarenal abdominal aorta were 67%, 38%, 38%, 48%, and 33%, respectively, and 57%, 67%, 52%, 33%, and 33% for those examined at a mean of 49±18 months after surgery, respectively. The false lumen regressed in 11 patients (42.3%). The aortic diameters were larger in the patients with a patent false lumen than those with a thrombosed false lumen at all levels of the descending aorta (p<0.05).ConclusionTAR and a more complete primary tear-resection can be accomplished with a relatively low-risk of morbidity and mortality. Enlargement of the distal aorta significantly correlated with the false lumen patency status.
