The venous anomaly of a persistent left superior vena cava (PLSVC) affects 0.3%-0.5% of the general population. PLSVC with absent right superior vena cava, also termed as "isolated PLSVC," is an extremely rare venous anomaly. Almost half of the patients with isolated PLSVC have cardiac anomalies in the form of atrial septal defect, endocardial cushion defects, or tetralogy of Fallot. Isolated PLSVC is usually innocuous. Its discovery, however, has important clinical implications. It can pose clinical difficulties with central venous access, cardiothoracic surgeries, and pacemaker implantation...

AIMS: Permanent pacemaker placement (PPM) is often required after valvular surgery and is especially common following tricuspid valve surgery [tricuspid valve repair or replacement (TVR)]. Literature suggests that surgical intervention for isolated tricuspid valve disease is becoming more prevalent. Predictors of PPM dependency following TVR are currently unknown and would be clinically useful from a prognostication standpoint. METHODS AND RESULTS: We conducted a multicentre, retrospective study to assess perioperative factors of TVR that predispose to PPM placement and long-term PPM dependency from 2008 to 2014...

OBJECTIVE: Native aortic valve calcium and transcatheter aortic valve oversize have been reported to predict pacemaker implantation after transcatheter aortic valve insertion. We reviewed our experience to better understand the association. METHODS: We retrospectively reviewed the records of 300 patients with no prior permanent pacemaker implantation who underwent transcatheter aortic valve insertion from November 2008 to February 2015. Valve oversize was calculated using area...

Interest in minimally invasive video-assisted mitral valve surgery (MIMVS) is rapidly growing. Data on concomitant atrial fibrillation (AF) ablation to MIMVS are still lacking. The present study investigates the long-term results of AF cryoablation concomitant to MIMVS. From October 2006-September 2014, 68 patients with mitral valve disease (age 65.9 ± 11.1 years, 34 men out of 68 patients, Euroscore log 5.4 ± 4.5) and drug-resistant AF underwent MIMVS via right minithoracotomy and concomitant left-sided AF endocardial cryoablation (Cryoflex Medtronic, Minneapolis, MN)...

A 69-year-old man was admitted after syncope followed with chest pain and signs of cardiac tamponade. He had undergone permanent dual-chamber pacemaker implantation 3 weeks earlier. Transthoracic echocardiography (TTE) confirmed a pericardial effusion, and urgent pericardial drainage was performed. Right ventricular perforation caused by active-fixation (screw-in) lead was verified by multislice computed tomography. The lead was extracted under fluoroscopy and bedside TTE monitoring in the operating room with cardiothoracic surgery backup...

Video capsule endoscopy (VCE) has been applied in the last 15 years in an increasing field of applications. Although many contraindications have been put into perspective, some precautions still have to be considered. Known stenosis of the gastrointestinal tract is a clear contraindication for VCE unless surgery is already scheduled or at least has been considered as an optional treatment modality. In patients with a higher incidence of stenosis, as in an established diagnosis of Crohn's disease, clinical signs of obstruction, prior radiation or surgical small bowel resection, a preceding test with the self-dissolving patency capsule can override this contraindication...

BACKGROUND: Controversy exists when performing surgical atrial fibrillation ablation whether there is an increase in postoperative complications using biatrial (BA) lesions compared with only left atrial (LA) lesions, and some studies indicate similar efficacy. This study compares the clinical outcomes of BA and LA ablation lesions in mitral valve surgery patients. METHODS: From 2004 through 2014, 2,137 patients had mitral valve surgery with or without other surgeries in a single center...

OBJECTIVES: Prosthetic valve dehiscence after aortic valve surgery in Behçet's disease patients is common. We aimed to validate the usefulness of our new technique 'subannular endomyocardial implantation of valve prosthesis' designed to prevent prosthetic valve dehiscence. METHODS: Subannular endomyocardial implantation of valve prosthesis involves suturing the sewing cuff of the valve prosthesis in the endomyocardium below the aortic annulus, which is based on the idea that annular tissue should be excluded from the suture line in Behçet's disease patients...

OBJECTIVES: Although septal myectomy is the technique of choice for hypertrophic cardiomyopathy, the surgical management of concomitant mitral valve lesions is controversial. Various complex surgeries have been proposed to address mitral valve lesions. We propose a simple option using an edge-to-edge mitral valve repair through the aortic valve in addition to the septal myectomy. METHODS: We performed an observational analysis of our prospectively collected database...

BACKGROUND: The widespread use of central venous catheters, ports, pacemakers, and defibrillators has increased the incidence of benign superior vena cava syndrome (SVCS). This study aimed at reviewing the results of open and endovascular treatment of SVCS. METHOD: Medical literature databases were searched for relevant studies. Studies with more than five adult patients, reporting separate results for the SVC were included. Nine studies reported the results of endovascular treatment of SVCS including 136 patients followed up for a mean of 11-48 months...

REVIEW
Carl L Backer
Patients with a failing Fontan frequently have dysrhythmias. This review will focus on the treatment of those dysrhythmias based on the 140 patients who have had a Fontan conversion with arrhythmia surgery at Ann & Robert H. Lurie Children's Hospital of Chicago (Chicago, IL). Important technical points to be emphasized are the following:• Atrial fibrillation is extremely common in patients with a failing Fontan and strong consideration should be given to a Cox-maze III during any Fontan conversion• Sinus node dysfunction is common post-conversion and all patients should receive a dual-chamber epicardial pacemaker• Careful preoperative imaging with either computed tomographic or magnetic resonance imaging is needed to predict re-entry problems at the time of repeat sternotomy• If the patient has protein-losing enteropathy, ascites, or a right or indeterminate ventricular morphology, strong consideration should be given to heart transplantation rather than a Fontan conversion and arrhythmia surgery...

Air embolism is an infrequent but potentially catastrophic complication. It could be a complication of invasive procedures including surgery, central line placement, positive pressure ventilation, trauma, hemodialysis, pacemaker placement, cardiac ablation, and decompression sickness. Usually, it does not cause any hemodynamic complication. In rare cases, it could lodge in the heart and cause cardiac arrest. We present a case of an 82-year-old white female who underwent computed tomography (CT) guided biopsy of right lung pulmonary nodule...

BACKGROUND: Surgical aortic valve replacement (SAVR) is the gold standard for treating aortic valve stenosis. It is a major operation that requires sternotomy and the use of a heart-lung bypass machine, but in appropriately selected patients with symptomatic, severe aortic valve stenosis, the benefits of SAVR usually outweigh the harms. Transcatheter aortic valve implantation (TAVI) is a less invasive procedure that allows an artificial valve to be implanted over the poorly functioning valve...

BACKGROUND: Carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating from enterochromaffin cells and secreting mainly serotonin. The diagnosis is based on clinical symptoms, hormone blood levels, radiological and nuclear imaging, and histological confirmation. However, most patients have metastases at the time of diagnosis because the clinical signs often remain unnoticed or are attributed to other abdominal conditions. In up to 50% of patients the endocardium is affected due to a hormonally active tumor profile...

AIM: Circulating levels of high-density lipoprotein cholesterol (HDL-C) are decreased in patients with heart failure (HF). We tested whether HDL-C serum levels are associated with cardiac contractile dysfunction in a minipig HF model. METHODS: Blood samples were collected from 13 adult male minipigs: 1) before pacemaker implantation, 2) 10 days after surgery, and 3) 3 weeks after high-rate LV pacing. Serum cholesterol efflux capacity (CEC), an index of HDL functionality, was assessed through four mechanisms: ATP Binding Cassette transporter A1 (ABCA1), ATP Binding Cassette transporter G1 (ABCG1), Scavenger Receptor-Class B Type I (SR-BI) and Passive Diffusion (PD)...

Sutureless and rapid-deployment aortic bioprostheses represent an emerging and promising technology for the treatment of aortic valve stenosis. Unlike traditional aortic bioprostheses, these devices are not hand-sewn, thus allowing a significant reduction in operative times, while facilitating minimally invasive surgery and complex cardiac interventions. Sutureless aortic valve replacement represents a less invasive treatment option and an excellent alternative to conventional aortic valve replacement in elderly and higher risk patients...

BACKGROUND: Aortic valve replacement with stentless bioprostheses has been shown to produce lower aortic gradients than stented bioprostheses, thus facilitating left ventricular mass regression and preventing heart failure. We sought to determine the long-term results of stentless biological aortic valve replacement over a 17-year follow-up. METHODS: Between 1996 and 2012, 2551 patients underwent isolated aortic valve replacement with a stentless prosthesis (Medtronic Freestyle) at a single center...
