Despite recent advances in surgical technique and perioperative care, the surgical correction of total anomalous pulmonary venous connection (TAPVC) remains a challenge. The major complication and the main cause of reoperation in TAPVC surgery are the occurrence of pulmonary venous obstruction (PVO). In the 1990s, sutureless repair was introduced as a technique to relieve PVO after TAPVC repair. Following the favorable outcomes for postoperative PVO, the indications for sutureless repair as a primary operation have been expanded to include infants who have preoperative PVO or those at risk of developing PVO after the repair of TAPVC...

OBJECTIVE: Current techniques for mitral valve repair (MVR) in Barlow's disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes of the mitral valve in Barlow's disease has been developed. METHODS: Between 2009 and 2013, 22 patients underwent minimally invasive MVR for Barlow's disease and severe mitral regurgitation (MR). A simple, standardized technique was applied, including resection of P2 segment of posterior mitral leaflet (PML) with preservation of the shortest chordae, transfer of the preserved chordae to A2, and implantation of a semi-rigid open ring...

A 55-year-old man with end-stage emphysema underwent a right single-lung transplantation through a posterolateral thoracotomy. The fifth rib was divided and fused back using a biodegradable pin made of polylactide acid and hydroxyapatite. Two weeks postoperatively, he suffered from central vein catheter-related sepsis due to methicillin-sensitive Staphylococcus aureus. After being successfully treated for sepsis, he was discharged. However, 3 months later, computed tomography revealed multiple loculated abscesses in the chest wall and the right pleural space...

Both aortic valve commissural detachment and commissural fenestration are rare causes of aortic regurgitation. In general, aortic valve replacement is the mainstay treatment for aortic regurgitation caused by commissural detachment or commissural fenestration. We herein describe valve-sparing aortic root re-implantation and aortic valve repair for aortic regurgitation and aortic root dilatation in an extremely rare case accompanied by both commissural detachment and commissural fibrous strand of fenestrated cusp...

INTRODUCTION: Talc pleurodesis is a well-established procedure performed to obliterate the pleural space to prevent recurrent pleural effusion and/or recurrent pneumothorax. Pleurodesis is commonly accomplished by draining the pleural fluid, if present, followed by either a mechanical procedure, such as abrasion, pleurectomy, or instillation of a chemical irritant into the pleural space, which results in inflammation and fibrosis which obliterates the pleural space. The reported complications of talc pleurodesis are hypoxemia, hypotension, tachycardia, dyspnea, chest pain, and fever...

INTRODUCTION: Lobectomy has been the standard surgery for even stage I lung cancer since the validity of limited resection for stage I lung cancer was denied by the randomized study reported in 1995. The aim of this non-randomized confirmatory going on since September 2013 is to confirm the efficacy of a segmentectomy for clinical T1N0 lung cancer with dominant ground glass opacity based on thin-slice computed tomography. METHOD: A total of 390 patients from 42 Japanese institutions are recruited within 4 years...

Although tracheobronchial stents are widely used for tracheal obstruction due to malignant or benign stenosis, stent migration has been reported as a major postoperative complication. A self-expandable metallic stent (SEMS) is more easily introduced compared with silicone stents. However, it is also difficult to remove or replace without complications. We report a new technique for successful SEMS adjustment using a flexible bronchoscope with two biopsy forceps.

This paper reports concomitant septal myectomy during minimally invasive aortic valve replacement through a right mini-thoracotomy. A 76-year-old woman was diagnosed as having aortic stenosis with systolic anterior motion of the mitral valve. The bulging septum was exposed by pulling up a traction suture placed at the annulus of the right coronary cusp; the anomalous chordae and muscle bundles attached to the septum were also resected. By setting an adequate intercostal thoracotomy and placing a traction suture, concomitant myectomy was safely performed even through a right mini-thoracotomy...

Cardiac resynchronization therapy (CRT) has been increasingly performed in patients having heart failure with dyssynchrony. We report a successful case of total thoracoscopic left ventricular (LV) lead implantation in CRT. A 77-year-old man with marked dyssynchrony of the LV wall motion and a low ejection fraction (EF17%) due to pacemaker-mediated cardiomyopathy was referred to us. CRT was planned, but percutaneous LV lead implantation proved difficult owing to anatomical variations. The LV lead was placed in the post-lateral wall of the LV base using a total thoracoscopic procedure...

Due to donor shortage, patients with refractory heart failure need to be supported on mechanical circulatory support (MCS). Critically, patients undergo several deployments of MCS in stages inevitably requiring blood products transfusion. MCSs per se along with blood products can trigger immune allosensitization. Antibody-mediated rejection (AMR) is associated with significant mortality after heart transplantation. Here, we present the case with high panel-reactive antibody over 95% who developed AMR early after heart transplantation...

Double-orifice mitral valve (DOMV) is a relatively rare cardiac anomaly. Although usually associated with various cardiac anomalies, co-presence of DOMV and noncompaction of left ventricular myocardium (NCLVM) is extremely rare. Here, we present a 24-year-old male who underwent mitral valve repair using artificial chordae and annuloplasty at the posterior commissure for severe mitral regurgitation (MR), resulting from flail anterior leaflet of the larger postero-medial orifice and dilatation of left ventricle with NCLVM...

OBJECTIVES: Although transcatheter aortic valve replacement (TAVR) is an excellent alternative procedure for high-risk patients with severe symptomatic aortic stenosis, it is often associated with life-threatening complications. We report on the emergency or elective use of veno-arterial extracorporeal membrane oxygenation (ECMO) to manage these complications. METHODS: Between December 2013 and February 2016, 46 patients underwent TAVR at our institution. Of these, 4 patients required emergency ECMO support and another 3 patients were electively placed on ECMO support at the start of the procedure...
