Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is among the most common enzymatic disorders of red blood cells. Cardiac surgeries on this group of individuals are associated with an additional risk in terms of impaired oxygenation, prolonged ventilation and increased risk of haemolysis. These patients have a very low threshold for haemolysis due to oxidative stress. Many commonly used drugs also predispose the individual for haemolysis when they are subjected to surgery. Here we present a known case of G6PD deficient patient with symptoms of breathlessness for the last nine years who was taken for surgery with pre-planned precautionary measures to avoid unnecessary haemolysis...

BACKGROUND: Robotic mitral valve (MV) repair is the least invasive surgical approach to the MV and provides unparalleled access to the valve. We sought to assess technical aspects and clinical outcomes of robotic MV repair for isolated posterior leaflet prolapse by examining the first 623 such cases performed in a tertiary care center. METHODS: We reviewed the first 623 patients (mean age 56±9.7 years) with isolated posterior leaflet prolapse who underwent robotic primary MV repair from 01/2006 to 11/2013...

BACKGROUND: Mitral valve cleft (MVC) is the most common cause of congenital mitral insufficiency, and MVC may occur alone or in association with other congenital heart lesions. Direct suture and valvuloplasty are the major and effective treatments for mitral regurgitation (MR) caused by MVC. Therefore, it is important to determine the location and magnitude of the pathological damage due to MVC when selecting a surgical procedure for treatment. This study explored the application value of transthoracic real-time 3-dimensional (3D) echocardiography (RT-3DE) in the diagnosis of MVC...

Background Minimally invasive surgical access through limited sternotomy reduces trauma and morbidity in cardiosurgical patients. However, until now, it is not the standard access for aortic root replacement. This study details our clinic's experience with minimally invasive implantation of valved conduits through partial upper sternotomy and the comparison to conventional full median sternotomy. Methods Between January 2012 and March 2016, a total of 187 patients underwent aortic root replacement with valved conduits in our department...

BACKGROUND: Permanent pacemaker (PPM) implantation after cardiac surgery is required in 0.4-6% of patients depending on cardiac surgery type. PPM implantation in the early postoperative period may reduce morbidity and postoperative hospital stay. We performed a retrospective review of electronic medical records of adult patients with coronary artery bypass grafting (CABG), valve surgery, or both, over a 3-year period. Our aim was to identify predictors of PPM requirements and PPM dependency on follow-up in the current surgical era...

Optimal exposure of the mitral valve is paramount in minimally invasive surgery (MIS) and a prerequisite for successful mitral valve repair or replacement. We report the concept of a new left atrial retractor (Karl Storz GmbH, Tuttlingen, Germany) dedicated to MIS. The effectiveness of the device was evaluated in a prospective series of 40 patients successfully operated at our institution.

Paravalvular leakage (PVL) occurs in 6%-15% of cases after surgical heart valve replacement. A percutaneous approach is increasingly used to close PVLs as an alternative to repeat surgery. Computed tomography (CT) can be used for simulation of fluoroscopic cardiac anatomy. This technique allows preprocedural definition of optimal C-arm angulations and PVL localization in reference to fluoroscopic views. It is very helpful for guidewire crossing of the PVL and positioning of the closure device. We report a case with the first use of dedicated software for fluoroscopic simulation (FluoroCT) in transcatheter mitral PVL closure...

INTRODUCTION: Neisseria macacae is a Gram-negative diplococcus, found in the oropharynx of healthy Rhesus Monkeys. Infections caused by N. macacae in humans are extremely rare. CASE PRESENTATION: We present here the first case of N. macacae infective endocarditis in a 65-year-old man with a native aortic valve infection complicated by a peri-aortic abscess. N. macacae was isolated from blood culture and was found on the cardiac valve using 16S rDNA detection. Despite an appropriate antibiotic therapy, and aortic homograft replacement, and mitral repair, the patient died 4 days after surgery from a massive hemorrhagic stroke...

Hybrid transcatheter Mitral Valve-in-Ring and Mitral Valve-in-Valve procedures can be an alternative to traditional surgical valve replacement in patients with high surgical risk. We present a case of a 65-year-old male with recurrent severe mitral regurgitation (MR) that failed two traditional surgical attempts due to severe chest fibrosis. We performed a mitral valve-in ring replacement with a Sapien valve followed by a mitral valve-in-valve replacement with a Melody valve. Patient had a residual paravalvular leak that was closed with a vascular plug...
