Acute pulmonary thromboembolism (APTE) is a highly prevalent condition (104-183 cases per 100,000 person-years) and is potentially fatal. Approximately 20% of patients with APTE are hypotensive, being considered at high risk of death. In such patients, immediate lung reperfusion is necessary in order to reduce right ventricular afterload and to restore hemodynamic stability. To reduce pulmonary vascular resistance in APTE and, consequently, to improve right ventricular function, lung reperfusion strategies have been developed over time and widely studied in recent years...

BACKGROUND: This study was conducted to explore the impact of renal dysfunction on short-term and mid-term outcomes in elderly patients. METHODS: Patients over 65 years of age receiving surgical ventricular restoration (SVR) were included in the study. They were stratified through estimated glomerular filtration rate (eGFR), with a cutoff point of 60 mL/min/1.73m2. Risk-adjusted analysis, including propensity score matching, was carried out to compare short-term and mid-term outcomes between the two groups of patients...

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect. Early surgical repair has dramatically improved the outcome of this condition. However, despite the success of contemporary approaches with early complete repair, these are far from being curative and late complications are frequent. The most common complication is right ventricle outflow tract (RVOT) dysfunction, affecting most patients in the form of pulmonary regurgitation, pulmonary stenosis, or both, and can lead to development of symptoms of exercise intolerance, arrhythmias, and sudden cardiac death...

Constipation can cause transient malfunction of the ventriculoperitoneal shunt (VPS). Patients with myelomeningocele or cerebral palsy are often diagnosed with hydrocephalus and constipation due to neurogenic bowel. These patients are more prone to VPS dysfunction, often requiring surgical revision. The authors report the case of a 6-year-old girl with a VPS that had been implanted due to hydrocephalus secondary to myelomeningocele. The patient was brought to the emergency department with intermittent headache, vomiting, constipation, and abdominal distension and pain...

Space-occupying tumor bed cysts have been reported after resection of intracranial tumors, although the exact mechanism of their pathogenesis is unclear. Opening of the ventricular system during the tumor resection appears to be a risk factor. Occlusion of the surgical opening of the ventricle using fibrinogen-coated collagen fleece has been suggested to restore the integrity of the ventricular system. Here we present a clinical image depicting an iatrogenic valve mechanism caused by a fleece intended to seal a surgical opening of the lateral ventricle, leading to development of a space-occupying tumor bed cyst and cerebrospinal fluid fistula...

Background: Engineered heart tissues (EHTs) present a promising alternative to current materials for surgical ventricular restoration (SVR); however, the clinical application remains limited by inadequate vascularization postimplantation. Moreover, a suitable and economic animal model for primary screening is another important issue. Methods: Recently, we used 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride chemistry (EDC) to initiate a strengthened, cytokine-conjugated collagenous platform with a controlled degradation speed...

INTRODUCTION: Craniopharyngiomas are dysontogenic tumors with benign histology but aggressive behavior. The surgical challenges posed by the tumor are well recognized. Neuroendoscopy has recently contributed to its surgical management. This study focuses on our experience in managing craniopharyngiomas in recent years, highlighting the role of combined endoscopic trans-ventricular and endonasal approach. CASE SERIES: Ninety-two patients have been treated for craniopharyngioma from 2000 to 2016 by the senior author...

BACKGROUND: Stented bioprosthetic valves (BPVs) are commonly used for surgical pulmonary valve (PV) replacement in postoperative congenital heart disease, but develop structural failure in a time-related fashion. The Melody transcatheter PV (TPV) (Medtronic, Minneapolis, Minn) has been used to treat BPV dysfunction, but there have been few studies in this population. METHODS: We performed a retrospective, multicenter study to evaluate Melody valve function in patients who underwent TPV replacement (TPVR) into a dysfunctional pulmonary BPV...

BACKGROUND: The postoperative ventricular adhesion after resection of central nervous system tumors can obstruct physiologic cerebrospinal fluid (CSF) circulation and cause temporal horn entrapment. The surgical goal is to restore physiologic flow of CSF. The authors reviewed their database to report their experience with endoscopic fenestration for treating entrapped temporal horn caused by atrial adhesions. All endoscopic operations performed from February 2015 to December 2016 were reviewed...

PURPOSE: To study capabilities of perfusion-metabolic myocardial scintigraphy for prediction of the left ventricular (LV) reverse remodeling after comprehensive surgical treatment of ischemic cardiomyopathy (ICMP). METHODS: The study included ICMP patients aged 56±7 years (n=32) who underwent surgical correction of LV dysfunction (myocardial revascularization, LV reconstruction, and mitral valve restoration). Inclusion criteria were significant coronary artery disease; myocardial infarction; New York Heart Association (NYHA) class III-IV heart failure; LV ejection fraction (EF) ≤45%; LV end-systolic index (ESI) >60 mL/m2; and LV akinesia or dyskinesia according to echocardiography...

OBJECTIVE: Quadricuspid truncal valves are susceptible to regurgitation, and tricuspid configuration is considered more durable after repairing the truncal valve. We report a new method by excising the excessive truncal cuspid to reconstruct a new competent aortic valve. METHODS: Bilateral pulmonary banding failed to stabilize a 4-month-old baby with type I truncus arteriosus and quadricuspid truncal valve with severe regurgitation, so surgery was performed. The aorta was transected, and the pulmonary arteries was separated from the aorta...

Mitral valve disease is common, with mitral regurgitation (MR) being the most frequent pathology. The etiology of MR is diverse, but, if left untreated, MR results in left ventricular (LV) volume overload, leading to remodeling, dilation of the LV, pulmonary hypertension, heart failure, and death. Mitral regurgitation is a high-risk diagnosis, yet a minority of symptomatic patients are referred for discussion of surgical treatment options. Percutaneous repair options are under development to address this clinical need and emphasize correction of the underlying anatomical pathology to restore mitral valve coaptation...

BACKGROUND: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) is a rather rare congenital anomaly that has a profound effect on heart function. This study aimed to retrospectively illustrate the perioperative clinical features, therapy experience, and midterm outcomes after surgical correction, and to determine the value of left ventricular ejection fraction (LVEF) and myocardial viability in differentiating critically ill patients among infants and children with ALCAPA...

Chiari type 1 malformation (CM1) rarely causes papilloedema, which is indicative of high intracranial pressure with or without ventricular dilatation. Furthermore, concomitant brain parenchymal abnormalities have not been reported to date. In this paper, the authors report on a young woman of CM1-induced intracranial hypertension (ICH) with diffuse brain edema with a focus on venous sinus assessment, and discuss the surgical strategy. A 24-year-old woman presented to Nagoya University Hospital complaining of 4-year history of severe occipital headache and blurry vision with slowly progressive worsening...

BACKGROUND: For over 50 years, surgical septal myectomy has been the preferred treatment for drug-refractory heart failure symptoms in patients with obstructive hypertrophic cardiomyopathy (HCM). Over this time in the United States, the majority of myectomy operations have been performed in a small number of select referral centers. METHODS: We have taken the opportunity to report results from the relatively new Tufts HCM Center and surgical program, incorporated 13 years ago, during which 507 myectomies (52±14 years of age; 56% male) were performed by one cardiothoracic surgeon, Dr...

Surgical relief of left ventricular outflow tract obstruction (LVOTO) in hypertrophic cardiomyopathy (HCM) requires more than septal myectomy. The procedure is currently the gold standard for all symptomatic HCM patients except those with comorbidities. The operation requires an individualized approach to restore the sophisticated functions of the left ventricular outflow tract (LVOT) without injury to the surrounding vital structures. The procedure should be tailored to deal with all the varied components of the obstruction including fibrous trigones, accessory tissues, and papillary muscle fusion...

The current standard of treatment of valvular diseases with severe functional and/or clinical consequences is the repair or replacement of the valve, which is usually surgical or, in specific scenarios, percutaneous. The available prosthetic valves, however, are not a magic bullet in the physicians' arsenal for the management of valvular diseases, since the age-dependent structural valve deterioration (SVD) and the need for prolonged systemic anticoagulation in the case of metallic prosthetic valves are not inconsequential during the lifespan of a patient with an implanted prosthetic valve...
