Cor triatriatum sinister is a rare congenital lesion encountered in children. It consists of a fibromuscular membrane that separates the left atrium into two chambers resulting in a triatrial heart and often occurs with other structural cardiac anomalies. The acquired form is uncommon and has only been reported after orthotopic heart transplantation or as a complication of infective endocarditis in adults. These cases were mostly because of hypertrophied atrial tissue or suture lines and torsion of the atrium...

OBJECTIVES: This study analysed the association between endothelin-1 (ET-1) and left atrial dimension (LAD) and evaluated whether ET-1 can be a predictor of postoperative atrial fibrillation (POAF) after mitral valve surgery. METHODS: This is a prospective study that enrolled 80 patients who underwent isolated mitral valve surgery. Plasma concentrations of ET-1 from peripheral venous blood were tested. POAF was detected using a telemetry strip or 12-lead electrocardiogram until the time of discharge...

OBJECTIVES: The transapical approach provides concurrent surgical access to the mitral and the aortic valves, the root of the aorta and the left atrium. We previously showed the feasibility of transapical cardioscopic (TAC) surgery in a non-survival porcine model. However, reproducibility and feasibility of ring implantation using TAC have not been reported. Therefore, in this study, we hypothesized that implantation of a mitral annuloplasty ring can be feasibly and safely carried out endoscopically via the apex of the heart...

To clarify the mechanisms underlying the development of displaced abomasum (DA), we repositioned DA in 12 cows by rolling and observed the course of redisplacement using X-ray fluoroscopy. Displacement of the abomasum was observed to follow three patterns: displacement to the left side of the abdominal cavity through the gap formed at the reticulum, atrium of the rumen and ventral sac of the rumen (n=7); displacement to the left side after cranial movement along the diaphragm (n=3); displacement to the right side after cranial movement along the diaphragm (n=2)...

OBJECTIVE: To investigate the clinical usefulness of echocardiography in the diagnosis of infracardiac total anomalous pulmonary venous connection (ITAPVC) in neonates and infants. METHODS: Retrospective analysis on 8 patients with ITAPVC was performed using echocardiography between April 2006 and December 2016. There were 4 boys and 4 girls with a mean age of 79.8 days (ranging from 15 to 195 days). A combined scanning via parasternal, subcostal and apical acoustic windows had been employed to diagnose ITAPVC and to trace the course and site of the anomalous pulmonary venous drainage, and to confirm the direction of the inter-atrial shunt and enlargement of right atrium and right ventricle...

The problem of pneumonectomy may result from an elimination of the extensive pulmonary vascular bed as a unit. Therefore this paper has indicated that 10 cases with the locally advanced lung cancers had been treated with some parenchymal sparing procedures including chemotherapy in order to avoid pneumonectomy. Six cases with preoperative chemotherapy were performed sleeve lobectomy in 3 cases, tangential pulmonary artery(PA) resection in 2, and left atrium partial resection in 1. One case with irradiation in vain was done sleeve LLL+lS4+5segmentectomy...

Aims: Quantitative real-time RT-PCR (RT-qPCR) has become the method of choice for mRNA quantification, but requires an accurate normalization based on the use of reference genes showing invariant expression across various pathological conditions. Only few data exist on appropriate reference genes for the human heart. The objective of this study was to determine a set of suitable reference genes in human atrial and ventricular tissues, from right and left cavities in control and in cardiac diseases...

REVIEW
M Cameli, E Incampo, S Mondillo
In chronic mitral regurgitation (MR) left atrium is one of the first cardiac structures that is involved in remodeling and ultrastructural changes for a progressive volume overload. Severe left atrial (LA) dilation on echocardiography and new onset of atrial fibrillation in asymptomatic patients with preserved Left Ventricular (LV) function, appeared as a Class IIb recommendation for consideration for surgical mitral valve repair in the actual guidelines. However, before atrial dilatation and dysfunction, several ultrastructural changes appear in the atrial muscle tissue that are difficult to identify with the standard echocardiography...

We report a rare case in which a patient required three surgeries with competing priorities. In a 68-year-old man diagnosed with an abdominal aortic aneurysm (AAA), computed tomography (CT) revealed an infrarenal AAA, unusual thickening of the sigmoid colon that suggested cancer, and a filling defect in the left atrium. We considered the disease stage, which affects prognosis, and the risk of complications that could interfere with the treatment of the other pathologies and developed a three-stage surgical strategy: (i) endovascular aortic repair, (ii) sigmoid colectomy, and (iii) resection of the left atrial mass...

BACKGROUND: Sepsis is the leading cause of lung injury in adults and can lead to acute respiratory distress syndrome (ARDS). Using a novel technique of isolated in vivo lung perfusion (IVLP), we hypothesized that normothermic IVLP will improve oxygenation and compliance in a porcine model of sepsis-induced lung injury. METHODS: Mature adult swine (n = 8) were administered lipopolysaccharide (LPS; 50 μg/kg over 2 hours) via the external jugular vein, followed by sternotomy and central extracorporeal membrane oxygenation (ECMO) cannulation (right atrium to ascending aorta)...

PURPOSES: Considering that pulmonary arterial obstruction decreases venous flow, we hypothesized that filling defects in pulmonary veins can be identified in areas adjacent to pulmonary embolism (PE). This sign was named the "pulmonary vein sign" (PVS), and we evaluated its prevalence and performance for PE diagnosis in computed tomography pulmonary angiography (CTPA). METHODS: This retrospective study enrolled consecutive patients with clinical suspicion of PE who underwent CTPA scan...
