PURPOSE: Left atrial volume (LA) and pulmonary vein (PV) anatomy may potentially relate to technical challenges in achieving stable and effective catheter position in case of atrial fibrillation (AF) ablation by means of "one-shot" catheters. The aim of this study was to investigate whether LA volume and PV anatomy, evaluated by computed tomography (CT) or magnetic resonance (MR) prior to ablation, predict acute and midterm outcome of AF ablation by nMARQ™. METHODS: We included 75 patients (mean age 58 ± 11 years, 67 % male) with symptomatic paroxysmal AF...

Pseudoaneurysm formation is a rare but potentially life-threatening complication after surgical repair of congenital heart disease. We present a boy with truncus arteriosus communis 14 years after homograft placement in pulmonary position. On follow-up, he presented progressive chronic homograft degeneration. Moreover, a large pseudoaneurysm in the right ventricular outflow tract was surprisingly depicted. We opted for a two-stage interventional approach.

The situs, or pattern of anatomic organization, of the subarterial infundibulum and of the great arteries and the degree of development of the subarterial infundibulum largely determine whether the great arteries are normally or abnormally related. There are 2 types of situs: solitus (normal) and inversus (a mirror image of solitus). Situs ambiguus means that the pattern of anatomic organization is uncertain or unknown. Infundibular development varies from absent, to atretic, to severely stenotic, to mildly or moderately stenotic; great arteries are solitus normally related or inversus normally related, respectively...

An intramural coronary artery in the setting of truncus arteriosus (common arterial trunk) is an uncommon association. Following an uneventful surgical repair, a neonate developed a low cardiac output state deteriorating into cardiac arrest shortly after arrival into the intensive care unit, requiring extracorporeal membrane oxygenation support. Echocardiography and angiography showed occlusion of the left coronary artery, prompting emergency surgical reexploration. A "slit-like" orifice with an intramural left coronary artery was successfully unroofed, allowing full recovery...

The unilateral absence of a proximal pulmonary artery (UAPPA) is rare and is most frequently accompanied by cardiovascular anomalies such as tetralogy of Fallot or septal defects. We report a patient with truncus arteriosus with UAPPA in which we performed a two-stage surgical repair. During the first palliative operation, a right modified Blalock-Taussig shunt was constructed to develop the hypoplastic right pulmonary artery. At 10 months, the patient underwent patch closure of a ventricular septal defect with integration of both pulmonary arteries, and reconstruction of the right ventricular outflow tract using a conduit...

It is customary, at the current time, to consider many, if not most, of the lesions involving the ventricular outflow tract in terms of conotruncal malformations. This reflects the introduction, in the early 1940s, of the terms conus and truncus to describe the components of the developing outflow tract. The definitive outflow tracts in the postnatal heart, however, possess three, rather than two, components. These are the intrapericardial arterial trunks, the arterial roots, and the subvalvar ventricular outflow tracts...

Cardiac neural crest cell (CNCC) ablation creates congenital heart defects (CHDs) that resemble those observed in many syndromes with craniofacial and cardiac consequences. The loss of CNCCs causes a variety of great vessel defects, including persistent truncus arteriosus and double outlet right ventricle. However, due to the lack of quantitative volumetric measurements, less severe defects, such as great vessel size changes and valve defects have not been assessed. Also poorly understood is the role of abnormal cardiac function in the progression of CNCC-related CHDs...

BACKGROUND: Percutaneous coronary intervention (PCI) for unprotected left main truncus (LMT) lesions is controversial. Inoperable status with advanced age, renal dysfunction, frailty, or patient request may require an unprotected left main PCI. PCI for LMT is not recommended in the typical clinical situation; however, when it is the only feasible option, the performance is not bad. We demonstrated the result of a cobalt-chromium everolimus-eluting stent (CoCr-EES) in the LMT stenting and serial changes via micro-computed tomography (μCT)...

The easternmost Nemastomatinae species, Sinostoma yunnanicum n. gen., n. sp., from northern Yunnan, China is described. It extends the geographic distribution of Nemastomatinae by roughly 3000 km southeastwards. Within Nemastomatinae Sinostoma displays plesiomorphic characters, including the long, basic bulb of the truncus shaft and the extremely short glans of penis, armed with short robust spines. Sinostoma may represent a relict line in the early evolution of nemastomatine harvestmen.

Thoracic aortic dilation (AD) has commonly been described in conotruncal defects (CTDs), such as tetralogy of Fallot, double outlet right ventricle and transposition of the great arteries, and truncus arteriosus. Several theories for this have been devised, but fairly recent data indicate that there is likely an underlying histologic abnormality, similar to that seen in Marfan and other connective tissue disease. The majority of aortic dissection in the general population occurs after the age of 45 years, and there have been very few case reports of aortic dissection in CTD...

BACKGROUND: Among patients with congenital heart disease (CHD), the coexistence of noncardiac congenital anatomic abnormalities (NC), genetic abnormalities (GA), and syndromes (S) may influence therapeutic strategies and outcomes. The appreciated prevalence of these abnormalities has risen because increased screening and improved diagnostic precision enable identification of these comorbidities in a larger fraction of neonates with CHD. We examined the contemporary prevalence and distribution of NC/GA/S across diagnostic groups among neonates undergoing cardiac operations using a large nationally representative clinical registry...

Persistent truncus arteriosus is a rare congenital cardiac disease with variable presentation. The exact preoperative diagnosis and delineation of anatomy are very important because the optimal timing and procedure for truncus arteriosus repair are decided on the basis of the morphological characteristics. Moreover, the presence of associated anomalies influences the surgical outcome and mortality in these patients. Dual-source computed tomographic evaluation with three-dimensional post-processing is highly valuable for delineating its precise morphology and to identify and characterize the associated anomalies...

Sleeve resection is a valid option in the surgical treatment of lung tumors, avoiding large resection. To ensure a good functional result and avoid post-operative complications like recent broncho-pleural fistulas and long-term stenosis, anastomosis between bronchi must be well performed. We report two cases of sleeve resection of the right lower lobe and show how we managed caliber discrepancy between the middle lobe bronchus and the truncus intermedius.

Knowledge of the incidence of spontaneous congenital abnormalities is critical for the accurate interpretation of findings in teratogenicity studies in any species. In this paper, results of the examination of 1739 neonatal Göttingen Minipigs are presented. Over the 2-year period under consideration, the incidence of external and visceral malformations was less than 0.2 and 0.1%, respectively. The most common external malformations were syndactyly, limb hyperflexion, domed head and scoliosis. The most common internal malformations were undescended testes, ventricular septal defect, diaphragmatic hernia and atrial septal defects...

25 formalin-fixed hearts of different tortoise species (Testudinidae) underwent gross-anatomical examination. The aim of the study was to illustrate the specific anatomy of the heart of these species in comparison to the data available in the literature. The examined tortoises showed the well-known basic structure of a reptile heart with two atria and a ventricle composed of three interconnected chambers. The right atrium was consistently slightly larger than the left atrium. The atrioventricular (AV-) valves emerged as double-flap valves, whereby the lateral leaflets were only present in a rudimentary form...

Congenital heart defects (CHD) affect approximately 7% of infants, and account for 3% of all infant deaths. CHD is most often caused by the defects associated with ductus arteriosus, which is a vessel that usually closes shortly after birth. The types of CHD include tetralogy of fallot, hypoplastic left heart syndrome, pulmonary atresia, total anomalous pulmonary venous return, transposition of great arteries, tricuspid atresia and truncus arteriosus. There are some risk factors that can increase the chance of a fetus developing CHD such as prematurity, an existing CHD in a first-degree relative, genetic syndromes, infections in utero, maternal drug consumptions and disorders...
