Hypertrophic cardiomyopathy is known as Leopard syndrome, which is a mnemonic rule for multiple lentigines (L), electrocardiographic conduction abnormalities (E), ocular hypertelorism (O), pulmonary stenosis (P), abnormalities of genitalia (A), retardation of growth (R), and deafness (D). We report the case of a 12-year-old patient with some of the abovementioned characteristics: hypertelorism, macroglossia, lentigines, hypospadias, cryptorchidism, subaortic stenosis, growth retardation, and hearing impairment...

BACKGROUND: Right ventricular (RV) dysfunction was shown to be associated with adverse outcomes in a variety of cardiac patients and is considered a risk factor for adverse outcome according to the updated Valve Academic Research Consortium criteria. OBJECTIVE: Our goal was to assess the impact of RV function at baseline on 1-year mortality among patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). METHODS: All patients with severe AS treated with TAVR from May 2007 to March 2015 at our center were included in the present study, and baseline and procedural characteristics were recorded for each patient...

INTRODUCTION: The segmentation and skeletonisation of images via computed tomography (CT) airway lumen volumetry provide a new perspective regarding the incorporation of this technique in medical practice. Our aim was to quantify morphological changes in the large airways of patients with acromegaly through CT and, secondarily, to correlate these findings with hormone levels and pulmonary function testing (PFT) parameters. METHODS: This was a cross-sectional study in which 28 non-smoker patients with acromegaly and 15 control subjects underwent CT analysis of airway lumen volumetry with subsequent image segmentation and skeletonisation...

Surgical re-implantation of the left coronary artery (LCA) is the treatment of choice in anomalous origin of left coronary artery from pulmonary artery (ALCAPA). Despite normalization of left ventricular function after surgery, residual coronary lesions or myocardial fibrosis may be found. The aim of this study was to detect regional left ventricular dysfunction predictive of coronary lesions or residual myocardial fibrosis using speckle tracking. We enrolled ten patients treated with surgical re-implantation of LCA for ALCAPA...

AIMS: The prognostic impact of elevated pulmonary arterial pressure (PAP) remains controversial in aortic stenosis (AS) and few studies focused on patients with preserved left ventricular ejection fraction (LVEF). We aimed to investigate the impact of pulmonary hypertension (PH), invasively derived, on survival in severe AS with preserved LVEF. METHODS AND RESULTS: Between 2000 and 2010, 749 patients (74 ± 8 years, 57% males) with preserved LVEF and severe AS without other valvular heart disease underwent cardiac catheterization...

We present a case of a 26-year-old female patient with bloating, postprandial nausea and recurrent vomiting after solid food intake. A gastric emptying scintigraphy showed a delayed gastric emptying, defining gastroparesis. Because of her past medical history of short stature and pulmonary stenosis, we initiated genetic counseling where the diagnosis of Noonan syndrome was made. Dietary therapy and medication with domperidone quickly led to relief of the discomfort due to gastroparesis. However, prokinetics are not indicated for long-term therapy, as cardiac arrhythmia may occur...

Transcatheter aortic valve implantation is a recent innovation in the treatment of severe aortic stenosis. On the other hand, several reports suggested that minimally invasive aortic valve replacement (MICS-AVR) is likely to be associated with reduced postoperative discomfort and faster recovery. Of note, an upper partial sternotomy for isolated aortic valve replacement( L-shaped MICS-AVR) has been accepted as the most common approach to the MICS-AVR. Since October 2013, we have preformed L-shaped MICS-AVR at our hospital...

A 6-year-old boy presented with dual drainage of left upper pulmonary vein, with connection to innominate vein inaddition to its normal connection to the left atrium. Despite relief of aortic stenosis at the age of 3 years, significant left to right shunt persisted. The dual drainage allowed successful percutaneous closure of the levoatriocardinal vein without obstruction to the pulmonary venous flow to the left atrium.

BACKGROUND: Surgical and transcatheter bioprosthetic valves (BPVs) in the pulmonary position in patients with congenital heart disease may ultimately fail and undergo transcatheter reintervention. Angiographic assessment of the mechanism of BPV failure has not been previously described. AIMS: The aim of this study was to determine the mode of BPV failure (stenosis/regurgitation) requiring transcatheter reintervention and to describe the angiographic characteristics of the failed BPVs and report the types and efficacy of reinterventions...

Neurofibromatosis type I (NFI), also called Von Recklinghausen disease, is an autosomal dominant disease secondary to a genetic mutation on the long arm of chromosome 17. This disorder affects neural crest cells. Cutaneous clinical forms are the most frequent with multiple benign skin neurofibromas, associated with café au lait skin spots and iris hamartomas. Vascular abnormalities in NF1 are rare but have also been well described. The most frequent abnormalities are characterized by arterial aneurysm degeneration, stenosis, and malformations...

REVIEW
Lucy M Safi, Ami B Bhatt
The arterial switch operation (ASO) is now the most frequently performed surgical correction in individuals with dextro-transposition of the great arteries (D-TGA). Patients who undergo this procedure as neonates have overall good clinical outcomes yet continued clinical follow-up is important to evaluate for postoperative complications. In this group, the highest mortality is in the immediate postoperative period and is generally associated with reimplantation of the coronary arteries. As these patients live into adulthood, longitudinal follow-up for other ASO complications including neo-pulmonary stenosis, right ventricular outflow tract (RVOT) obstruction, or neo-aortic root dilation and resulting aortic insufficiency should be performed...

The management of pulmonary atresia with a ventricular septal defect (PA/VSD) depends on the anatomy of the pulmonary artery or on the surgical strategy used at individual institutions. In our institution, we adopted a right ventricle-to-pulmonary artery (RV-PA) shunt in 2011 as a palliative procedure for PA/VSD to overcome the disadvantages of a Blalock-Taussig shunt. We evaluated the results of the RV-PA shunt as initial palliative surgery for PA/VSD. Thirteen patients with ductus-dependent PA/VSD from August 2011 to August 2015 were enrolled...

REVIEW
Vikas Pathak, Ray W Shepherd, Samira Shojaee
Tracheobronchial tuberculosis (TBTB) is reported in approximately 10% to 39% of the patients with pulmonary tuberculosis. It is defined as the tubercle infection of the trachea and or bronchi. Due to its non-specific presentation, insidious onset and normal chest radiography in about 10-20% of the patients, the diagnosis is delayed. Bronchoscopy is the most definite method of diagnosis which provides adequate specimens for microbiological and histopathological diagnosis. Tracheobronchial stenosis is one of the most common long term complications of TBTB resulting in significant morbidity...

A non-contractile transannular patch (TAP) in the right ventricular outflow tract (RVOT) contributes to ventricular dysfunction after tetralogy of Fallot (TOF) repair. We compared regional right ventricular (RV) strain in repaired TOF with valvar pulmonary stenosis (VPS) after balloon valvuloplasty to investigate the effects of TAP. Retrospective review of 26 cardiac magnetic resonance studies of TOF (n = 13) and VPS (n = 13) subjects matched by degree and duration of pulmonary regurgitation (PR). Feature tracking strain analysis was performed...

Severe and critical central airway obstruction causing impaired ventilation and/or oxygenation can impose tremendous challenges on the interventional pulmonologist. Near total airway obstruction can rapidly evolve into potentially fatal complete airway occlusion during bronchoscopic airway manipulation under moderate sedation; as well as during the induction of the general anesthesia. Although there are currently interventional pulmonary procedures available to tackle the critical airway obstruction in extreme situations, cardio-pulmonary bypass should be considered prior to the intervention to maintain the adequate gas exchange during the procedure...
