The case is reported of a 79-year-old female who received a patch augmentation of the tricuspid anterior and septal leaflets with a resected left atrial wall to address recurrent tricuspid regurgitation, including tricuspid valve tethering. The patient was admitted to the authors' hospital for chronic heart failure with paravalvular leakage after aortic valve replacement and recurrent severe tricuspid regurgitation. She had undergone two previous cardiac surgeries. Re-tricuspid repair required an augmentation of the tricuspid valve leaflets in addition to tricuspid annuloplasty...

BACKGROUND: Various approaches such as antegrade trans-septal, retrograde transfemoral and transapical techniques have been used to close mitral paravalvular leak (PVL) in patients with an aortic prosthesis. During the implementation of these techniques, an arteriovenous guidewire loop is often created for device delivery. However, passing through a mechanical aortic valve may cause hemodynamic compromise and prolong the procedure. To date, no studies have evaluated antegrade mitral PVL closure without the use of an arteriovenous wire loop in patients with a mechanical aortic prosthesis...

BACKGROUND: Left ventricular (LV) function and the dimensions of aortic valves from normally functioning bicuspid aortic valve (BAV) patients were compared with those of healthy control patients. A comparison between patients with antero-posterior BAV (BAV-AP) or right-left BAV (BAV-RL) was also performed, and the determinants of aortopathy and LV function were investigated. METHODS: Sixty-eight patients with aortic velocities <2 m/s and trivial or mild aortic regurgitation were included in the study...

BACKGROUND: Numerous surgical techniques exist to treat nasal septal perforation (NSP). The surgical closure of large NSPs (>2 cm) is still challenging. Posterior septectomy has been reported as a simple alternative to treat large NSP, yet its mechanisms for symptom relief are not clear, and if failed, its consequence cannot be easily reversed. METHODS: Ten NSP patients were recruited: 5 underwent posterior septectomy and 5 underwent conventional flap or button repair...

A 200∼240 kb SH2B1-containing deletion region on 16p11.2 is associated with early-onset obesity and developmental delay. Here, we describe monozygotic twin brothers with discordant clinical presentations. Intrauterine fetal growth restriction was present in both twins. Additionally, twin A exhibited coarctation of aorta, left ventricular noncompaction, atrial septal defect, pericardial effusion, left hydronephrosis, and moderate developmental delay, whereas twin B exhibited single umbilical artery. Chromosome microarray analysis was performed on both twins and their parents...

A 6-month old female alpaca cria presented to The Ohio State University for evaluation of a cardiac murmur. Echocardiography revealed a left-to-right shunting patent ductus arteriosus, a restrictive left-to-right shunting perimembranous ventricular septal defect, and secondary moderate left atrial and ventricular dilation. Aortic root angiography demonstrated a type IIA patent ductus arteriosus (PDA). Interventional closure of the PDA was successfully performed, without complication, using an Amplatz canine duct occluder...

INTRODUCTION: Cardiac pacing from the right ventricular apex is associated with detrimental long-term effects and non-apical pacing locations may be associated with improved outcomes. There is little data regarding complications with non-apical lead positions. The aim of this study was to assess long-term outcomes and lead-related complications associated with differing ventricular lead tip position. METHODS AND RESULTS: All adult patients who underwent dual-chamber pacemaker implantation from 2004-2014 were included if they had post-procedure chest radiographs amenable to lead position determination...

BACKGROUND: This study sought to evaluate the feasibility, safety, and efficacy of perventricular device closure of a doubly committed sub-arterial ventricular septal defect (dcVSD) through a left infra-axillary approach. METHOD: Forty-five patients, with a dcVSD of less than 8 mm in diameter, were enrolled in this study. The pericardium was exposed and opened through a left infra-axillary mini-incision. Two parallel purse-string sutures were placed on the right ventricle outflow tract and under transesophageal echocardiography guidance, a delivery sheath loaded with the device was inserted into the right ventricle and advanced through the defect into the left ventricle...

The inferior vena cava (IVC) is a rare site of focal atrial tachycardia (AT). Here, we report a 20-year-old woman who underwent catheter ablation for anti-arrhythmic drug-resistant AT originating from the IVC. She had undergone open-heart surgery for patch closure of an atrial septal defect 17 years previously and permanent pacemaker implantation for sinus node dysfunction 6 years previously. The AT focus was at the anterolateral aspect of the IVC-right atrial junction, and it was successfully ablated under three-dimensional electroanatomical-mapping guidance...

BACKGROUND: Recent studies have demonstrated that surgical ventricular septal defect closure in childhood is associated with reduced functional capacity and disruption of the right ventricular force-frequency relationship during exercise. To further describe long-term cardiac function, we performed a non-invasive assessment of cardiac index during exercise in adults having undergone surgery for ventricular septal defect in early childhood. METHODS: A total of 20 patients (surgical age 2...

This study aimed to test the diagnostic performance of a fully quantitative fibrosis assessment tool for liver fibrosis in patients with chronic hepatitis B (CHB), primary biliary cirrhosis (PBC) and non-alcoholic steatohepatitis (NASH). A total of 117 patients with liver fibrosis were included in this study, including 50 patients with CHB, 49 patients with PBC and 18 patients with NASH. All patients underwent liver biopsy (LB). Fibrosis stages were assessed by two experienced pathologists. Histopathological images of LB slices were processed by second harmonic generation (SHG)/two-photon excited fluorescence (TPEF) microscopy without staining, a system called qFibrosis (quantitative fibrosis) system...

Minimally invasive atrial septal defect closure and tricuspid annuloplasty in female patients are normally performed through a right submammary anterior minithoracotomy approach. However, when the aortic root is located higher, the direction of aortic cannulation becomes not ideal through the submammary incision. In such cases, transareolar approach is useful. Through this approach, aortic cannulation and tricuspid operation can be performed with endoscopic assistance, and ASD closure can be performed under direct vision...

Surgical closure of nasal septal perforation is one of the most challenging procedures in nasal surgery. During the last decade, many endoscopic repair techniques have been described with a success of post-operative repair between 76.4% and 100%. The advantages of this approach are its minimal invasiveness (with no external scars), optimal exposure of the operative field (with better visibility of structures) and good control of perforation margins. The drawbacks are that it is time-consuming and can be difficult to perform, requiring years of endoscopic experience...
