Hydrocephalus, where cerebrospinal fluid (CSF) production rate is greater than reabsorption rate, leads to impaired neurological function if left untreated. Ventriculoperitoneal shunts (VPS) are implanted in the brain ventricles to route CSF. VPS systems have a high failure rate, and failure symptoms resemble symptoms of common maladies. The current gold standard for shunt diagnosis, surgical intervention, poses high risk and requires an expensive procedure for patients. Current non-invasive methods lack proper insight to assist physicians...

BACKGROUND: Patients with failed bioprostheses are an increasing population at high risk for redo surgery. Valve-in-valve transcatheter aortic valve implantation is a promising alternative but a limited number of first-generation devices have proven efficacy in all cases. METHODS: Patients with degenerated bioprostheses at high risk for redo surgery were included in the registry after being assigned to valve-in-valve intervention by a local heart team. Main basal and follow-up data (at 1 month and 6 months) of patients undergoing valve-in-valve transcatheter aortic valve implantation with the Lotus valve system (Boston Scientific, Natick, MA) in three high-volume Italian centers were entered in the registry...

Malignant ventricular arrhythmias and sudden cardiac death may late happen in repaired tetralogy of Fallot, although probably less frequently than previously thought, especially with the advent of new surgical techniques/management. Ventricular tachycardias are caused by reentry around the surgical scars/patches and valves. Many predictive factors have been proposed, which suffer from poor accuracy. There is currently no recommended indication for prophylactic implantable cardioverter defibrillator implantation-except maybe in the case of multiple risk factors-while radiofrequncy ablation may be proposed in secondary prevention with or even without a back-up implantable cardioverter defibrillator in selected cases...

The comparative outcomes of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in diabetes mellitus (DM) patients are scarce. We aimed to assess and compare the outcomes of TAVR versus SAVR in DM patients using the Nationwide Inpatient Sample database from 2011 to 2013. A complete case analysis was performed for the multivariate analysis and cases with missing data were excluded. The primary end point was in-patient all-cause mortality and secondary outcomes were perioperative complications...

Vanishing lung syndrome is a clinical presentation of giant bullous emphysema associated with significant morbidity and mortality. We present a case of a 50-year-old white woman with vanishing lung syndrome who presented with a spontaneous secondary pneumothorax and an uncontrolled bronchopleural fistula. The large bronchopleural fistula was initially controlled with a double-lumen endotracheal tube and a tube thoracostomy. After surgical efforts failed, complete left lung isolation was performed with multiple intrabronchial valves...

A 64-year-old man with extensive tumorous infiltration of the pulmonary valve underwent partial resection of a tumor of the right ventricular outflow tract and replacement of the affected valve. A diagnosis of immunoglobulin-G4 related disease of the heart was made based on the immunohistologic findings. One year after the surgical resection, growth of the tumorous mass was observed, and steroid therapy was initiated. He had no sign of tumor progression four years after the steroid therapy.

Tricuspid regurgitation (TR) is a common finding in patients with left-sided valvular or myocardial disease. However, many patients with severe symptomatic TR are deemed inoperable or at high surgical risk, often due to comorbidities and the need for redo sternotomy. Thus, despite the poor prognosis associated with this condition, few patients undergo isolated surgical tricuspid valve repair. Therefore, there is an unmet clinical need for less invasive therapeutic options for these patients. In recent times, several transcatheter therapies have emerged for treating TR, with promising safety and preliminary efficacy results...

The technique for successful surgical correction of an anomalous origin of the right coronary artery from the opposite aortic cusp with an aberrant course between the aorta and pulmonary artery is illustrated in a symptomatic 62-year-old woman. The intramural course of the right coronary artery traversed the tip of the commissure between the anterior and posterior leaflets, and its repair entailed unroofing of the intramural segment from inside the aortic intima. This technique required resuspension of the overlying commissure to maintain optimal aortic valve leaflet coaptation and prevent aortic insufficiency...

INTRODUCTION: Optimal timing of surgical treatment for infective endocarditis (IE) complicated by intracranial hemorrhage remains controversial. PRESENTATION OF CASE: A 43-year-old man with IE received appropriate antibiotic therapy but had recurrence of cerebral infarction and intracranial hemorrhage (ICH). Emergency valve surgery was performed 2days after ICH onset because of heart failure and recurrence of cerebral complications. Postoperatively, he showed no neurologic symptoms; neuroimaging showed no enlargement of ICH...

OBJECTIVE: Hybrid operative thrombectomy (HOT) is a novel technique for the treatment of acute iliofemoral deep venous thrombosis (IFDVT) and is an alternative to percutaneous techniques (PTs) that use thrombolytics. In this study, we compare perioperative and intermediate outcomes of HOT vs PT as interventions for early thrombus removal. METHODS: From July 2008 to May 2015, there were 71 consecutive patients who were treated with either PT (n = 31) or HOT (n = 40) for acute or subacute single-limb IFDVT...

The optimal decision regarding whether to repair or replace the tricuspid valve (TV) remains controversial in patients with very severe functional tricuspid regurgitation (TR). We sought to compare clinical outcomes of TV repair versus replacement for very severe TR associated with severe TV tethering. We included 96 consecutive patients (20 men, 58 ± 11 years of age) who had both severe tethering of TV and very severe functional TR and consequently underwent TV surgery during left-sided valve surgery. TV repair was performed on 79 patients (repair group), whereas 17 patients underwent TV replacement (replacement group)...

Rupture of aneurysm of sinus of Valsalva into the right atrium mimicking tricuspid valve endocarditis is a rare presentation. We review a case of spontaneous rupture of aneurysm of sinus of Valsalva into the right atrium presenting as a murmur. Transthoracic echocardiogram showed a mobile mass that appeared to be attached to the tricuspid valve leaflet with moderate tricuspid regurgitation suggestive of tricuspid valve endocarditis. The diagnosis was confirmed as spontaneous rupture of noncoronary sinus in to the right atrium by transesophageal echocardiogram...

Atrial fibrillation (AF) and valvular heart disease (VHD) frequently coexist and independently increase mortality1. Bioprosthetic valve implantation (surgical or transcatheter), is a common, increasingly utilized treatment for VHD2. Patients with AF and bioprosthetic valves require anticoagulation to prevent thromboembolic events. Non-vitamin K oral anticoagulants (NOACs) are safe and efficacious alternatives to vitamin K antagonists for anticoagulation in AF. However, guidelines recommend against NOACs in patients with bioprosthetic valves, citing a lack of supporting data...

The assessment and management of tricuspid valve disease evolved significantly in the last decade. Tricuspid regurgitation is a frequent heart valve disease and it is most often secondary, due to annular dilatation and leaflet tethering from right ventricular remodelling. The indications for tricuspid valve surgery are several and mainly related to the underlying disease, to the severity of the regurgitation and to the right ventricular function. Moreover, surgical tricuspid repair has been avoided for years, because of the erroneous concept that tricuspid regurgitation should disappear once the primary pathology on the left heart has been resolved...

INTRODUCTION: Recently, the surgical management of nasal tumors has been greatly influenced by advanced endoscopic techniques. To achieve complete endoscopic resection of large obstructing nasal tumors, a sufficient corridor for adequate exposure is also required. In the Japanese language, TACMI means "master expert," and herein we describe an endoscopic technique with novel elements that we term transseptal access with crossing multiple incisions (TACMI). This approach enables a direct transseptal approach to the pedicle through tumor transposition while allowing complete septal reconstruction and stability...

Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...
