In healthy divers, the occurrence of immersion pulmonary oedema (IPE) is commonly caused by contributory factors including strenuous exercise, cold water and negative-pressure breathing. Contrary to this established paradigm, this case reports on a 26-year-old, well-trained combat swimmer who succumbed to acute IPE during static immersion in temperate (21°C) water, while using a front-mounted counterlung rebreather. The incident occurred during repeated depth-controlled ascent practice at the French military diving school...

INTRODUCTION: The diagnosis of ALCAPA syndrome is sporadic in adulthood, of the limited cases in the literature most are incidental or without symptoms. There is a broad spectrum of clinical manifestations of ALCAPA syndrome however, including sudden cardiac death. CASES: We present herewith a series of 12 consecutive patients with ALCAPA, all diagnosed in adulthood (between 18 and 73 years of age). Five patients developed symptoms (breathlessness) after the fourth decade of life, 3 were undiagnosed despite a history of previous mitral valve repair, one presented with heart failure, one with resuscitated cardiac arrest, whereas two patients were asymptomatic...

OBJECTIVES: Minimally invasive aortic valve replacement (MIAVR) can be technically demanding and may lead to prolonged operative time. We evaluated the intraoperative and postoperative patient outcomes following implementation of 2 facilitating technologies (FT) in MIAVR: the Cor-Knot titanium fastener and Custodiol-histidine-tryptophan-ketoglutarate solution. METHODS: A total of 299 patients underwent MIAVR from 2008 to 2016; 172 (57.5%) patients were included in the FT group and 127 (42...

INTRODUCTION: the incidence of invasive infections caused by pneumococcus (Streptococcus pneumoniae) has declined since generalized vaccination with pneumococcal conjugated vaccine, but it is still a prevalent pathogen in children. Amongst pneumococcal invasive infections, IE (infectious endocarditis) is rare, with an incidence between 1 and 7%. CASE REPORT: We describe the case of a previously healthy 4 year old boy, who had received one dose of 10-valent pneumococcal conjugate vaccine who presents with fever, a new heart murmur and heart failure...

PURPOSE OF REVIEW: The past couple of decades have brought tremendous advances to the field of pediatric and adult congenital heart disease (CHD). Percutaneous valve interventions are now a cornerstone of not just the congenital cardiologist treating patients with congenital heart disease, but also-and numerically more importantly-for adult interventional cardiologists treating patients with acquired heart valve disease. Transcatheter pulmonary valve replacement (tPVR) is one of the most exciting recent developments in the treatment of CHD and has evolved to become an attractive alternative to surgery in patients with right ventricular outflow tract (RVOT) dysfunction...

OBJECTIVES: Postoperative left pulmonary artery (PA) or bronchus compression occasionally follows narrowing of the retroaortic space after the Norwood procedure. We examined hypoplastic left heart syndrome (HLHS)-specific anatomical malformations and hypothesized that a long main pulmonary arterial trunk might contribute to a larger retroaortic space. In this study, we introduced a modified Norwood procedure [pulmonary artery trunk-saving method (PATS)] and evaluated the results. METHODS: HLHS-specific anatomical malformations were examined using computed tomographic data from 23 consecutive patients who underwent bilateral pulmonary banding...

OBJECTIVES: The Ross procedure has demonstrated excellent results when performed in patients with aortic stenosis or mixed aortic valve disease [aortic stenosis and aortic regurgitation (AR)]. However, due to its reported risk of late reoperation, it is not recommended under current guidelines for patients presenting with bicuspid aortic valve and pure AR. We have analysed our own results in light of this recommendation. METHODS: Between 1993 and 2016, 129 consecutive patients with a mean age of 34...

BACKGROUND: To investigate the feasibility and mid-term results of percutaneous pulmonary valve implantation (PPVI) in patients with conduit free or "native" right ventricular outflow tracts (RVOT). METHODS AND RESULTS: We identified all 18 patients with conduit free or "native" right ventricular outflow tract, who were treated with percutaneous pulmonary valve implantation (PPVI) in our institution. They were divided into two groups - these in whom the central pulmonary artery was used as an anchoring point for the preparation of the landing zone (n=10) for PPVI and these, in whom a pulmonary artery branch was used for this purpose (n=8)...

BACKGROUND: Controversy remains regarding the optimal surgical approach for children with supravalvular aortic stenosis (SVAS). METHODS: Since 1997 we have used Brom three-patch aortoplasty for patients with SVAS. We prefer computed tomography (CT) imaging for preoperative evaluation rather than cardiac catheterization as it avoids the well-known morbidity of general anesthesia. The purpose of this study was to present our intermediate-term results of this strategy...

BACKGROUND: Twenty percent of patients born with congenital heart disease present with right ventricular outflow tract abnormalities. These patients require multiple surgical procedures in their lifetime. Transcatheter pulmonary valve replacement (TPVR) has become a viable alternative to conventional pulmonary valve and right ventricular outflow tract surgery in pediatric and adult populations. In this retrospective review, we analyze the perioperative management of adult patients who underwent TPVR in our center...

In almost every type of artificial valve, structural failure has been described. We are reporting on a case of a sudden leaflet escape of an Edwards TEKNA mitral valve prosthesis 12 years after implantation. The patient had a sudden onset of dyspnea and severe pulmonary edema with subsequent cardiogenic shock. An emergency mitral replacement was successfully performed. A multi-detector computed tomography scanning and three-dimensional imaging showed two fragments that had embolized in the terminal aorta and the left common iliac artery...

A 47-year-old woman with a medical history of Raynaud's phenomenon presented with fever, cough and shortness of breath. She was found to have left lower lobe consolidation and pleural effusion and was treated as a case of pneumonia. During the hospital course, her respiratory status worsened, and she was intubated on the third hospital day. To investigate the high A-a gradient, a Computerized Tomographic Pulmonary Embolism (CTPE) study was done which identified a large left lower pulmonary artery embolism. She was also found to have a new murmur, and an echocardiogram demonstrated a large lesion on tricuspid valve...

Although vancomycin administration is recommended for the treatment of infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA), it is unclear whether an alternative agent, daptomycin, can be used to treat IE with pulmonary complications. A 26-year-old female who had undergone surgical repair of a ventricular septal defect as an early teenager presented with fever, headache, and vomiting. She was admitted to our hospital and diagnosed with right-sided IE with septic pulmonary embolism caused by MRSA...

OBJECTIVES: Mitral regurgitation (MR) in the majority of infants with an anomalous left coronary artery from the pulmonary artery (ALCAPA) has been shown to improve without concomitant mitral valve repair. However, the outcome of MR in older children with ALCAPA is unclear. The purpose of this study was to compare the outcome of MR following the ALCAPA repair in infants and older children. METHODS: Forty-six patients (34 were younger than 1 year and 12 were aged 1-12 years) underwent the repair for ALCAPA in our institution from June 2006 to June 2016...

OBJECTIVES: Endomyocardial biopsy sampling is used to check acute rejection after cardiac transplant. However, it may lead to tricuspid valve injury and cardiac perforation; therefore, less invasive tools may be useful. Right heart catheterization provides valuable information about cardiac hemodynamics. Herein, we aimed to determine the correlation of right heart catheterization parameters with acute rejection and death during cardiac transplant follow-up. MATERIALS AND METHODS: We retrospectively evaluated follow-up right heart catheterization and endomyocardial biopsy results from 47 adult patients who underwent cardiac transplant at Başkent University Faculty of Medicine between 2004 and 2016...
