Unlike a few decades ago, today most patients with congenital heart disease reach adulthood after intervention or reparative surgery. As complete correction is generally not possible, a patient population with great complexity and a particular challenge to medical management is rising and a regular follow-up is mandatory. The aim of care is the timely recognition of residual or associated problems. Frequency and intensity of follow-up examinations depend on type and complexity of the lesion. The standard repertoire at follow-up consists of a specific history, clinical examination, ECG, Holter-monitoring, exercise tests, and echocardiography. Depending on the indication, cardio-MRI, CT scan, and sophisticated cardiac catheterization may become necessary. Long-term complications like rhythm disturbances, pulmonary hypertension, or heart failure are frequent, despite optimal care. Acute complications like arrhythmias, infective endocarditis, cerebral events, cerebral abscesses, aortic dissection, pulmonary embolism, and bleeding have to be recognized early and treated appropriately. Additional focus has to be placed on counseling and management of noncardiac disease and surgery, pregnancy and delivery, exercise at work and in private life, driving, and insurance issues. Training and certification of physicians as well as the establishment of specialized centers will help to ensure high quality health care for the affected patient population.

Whipple disease is a disorder caused by Tropheryma whipplei, a ubiquitous Gram-positive bacillus. In addition to gastrointestinal manifestations, many other systems may be involved in Whipple disease. Pulmonary hypertension (PH) is a rare manifestation of Whipple disease, and its clinical course is not well established. We report a case of a 45-year-old woman who presented with typical gastrointestinal manifestations of Whipple disease, which was diagnosed by duodenal biopsy. She was also noted to have elevated pulmonary arterial pressures on transthoracic echocardiography. There was no evidence of left-sided valvular disease, hypertrophy, or dyskinesis, and there was no evidence of endocarditis. The patient was started on intravenous ceftriaxone for 6 weeks and then transitioned to oral trimethoprim-sulfamethoxazole for a year. The patient demonstrated clinical improvement, endoscopic and histologic improvement, and also resolution of PH. This is the third reported case of PH that is convincingly secondary to Whipple disease that resolved after appropriate antibiotic therapy.

The number of patients with congenital heart disease exceeds now the number of children born with these defects. This is related to the "success story" of cardiac surgery and interventional catheterism. The prevalence of this new population is about 3-4 patients/1000 adults in the general population. Some of these patients have native disease, with a relatively good tolerance up until adulthood. Nevertheless, these patients are rarely completely cured, and they face problems such as threatening atrial or ventricular arrhythmias, heart failure (more often right heart failure) endocarditis or pulmonary hypertension. Patients with complex diseases are more at risk of complications. Situations "at risk" are described in this review, one of them being the loss of follow up particularly during the transition between paediatric care and adulthood.

In 2010, an 82-year-old patient received a diagnosis of stage IV chronic obstructive pulmonary disease, ischemic dilated cardiomyopathy, severe secondary pulmonary hypertension, atrial fibrillation with slow ventricular response, and severe tricuspid regurgitation. In December 2011, he was hospitalized for exacerbation of chronic obstructive pulmonary disease. The patient received antibiotics via injections (for 2 weeks through a peripheral venous catheter). In February 2012, he returned to the hospital with congestive heart failure and vascular purpura skin lesions. The echocardiography examination revealed a rupture of cordage afferent to the septal tricuspid valve. Because blood cultures were sterile after 10 days and no vegetation was revealed, the Duke criteria were not fulfilled. In March 2012, the patient returned with congestive heart failure, fatigue, and anorexia. Echocardiography evaluation then revealed attached septal tricuspid valve vegetation. The Duke criteria were now satisfied. The patient received antibiotics at doses recommended for infective endocarditis, with a favorable outcome.

A 47 year-old male with a history of refractory ascites presented to our centre complaining of dyspnoea, abdominal distention, and weight gain. He was admitted under a medical team for investigation and management. Work-up excluded all common aetiologies of ascites. Echocardiography revealed severe aortic regurgitation (AR) with a dilated left ventricle but no right heart pathology or pulmonary hypertension. He underwent mechanical aortic valve replacement. Intra-operatively, a prolapsing left coronary leaflet of the aortic valve with frayed edges raised suspicion of resolved infective endocarditis. Postoperative course was uneventful. Following replacement of the aortic valve, the patient was completely free of ascites. This case demonstrates that ascites can be an unusual clinical presentation of severe aortic regurgitation, which may respond to aortic valve replacement.

We report a case of a patient with severe mitral regurgitation (MR) due to infective endocarditis with preserved left ventricular systolic function complicated by severe pulmonary hypertension, right ventricular (RV) dysfunction, and cardiogenic shock. He was evaluated by cardiothoracic surgery for mitral valve replacement (MVR). It appeared that the high pulmonary artery pressure (PAP) had been chronic with acute worsening, thus raising concerns that it may not promptly reverse after MVR, putting him at high risk for postoperative RV failure and increasing the risk of mortality. A TandemHeart (TH) percutaneous ventricular assist device (pVAD) was placed with improvement in hemodynamics following which MVR was done. To our knowledge, this is the first report of the preoperative use of the TH pVAD in severe acute MR for hemodynamic stabilization in preparation for MVR.

A 21-year-old woman in the 16th week of pregnancy was admitted due to acute presentation of severe exertional dyspnea. She had undergone mitral valve replacement (MVR) with bioprosthetic valve for infective endocarditis 2 years ago. She developed congestive heart failure from mitral bioprosthetic valve stenosis due to early structural valve deterioration. She also had severe pulmonary hypertension and underwent a redo MVR using a mechanical valve prosthesis with good maternal outcome but fetal demise. This report brings up the debate about what type of valve should be used in women in reproductive age, and discusses the management of severe mitral stenosis and stenosis of a bioprosthetic valve during pregnancy. Surgical options can almost always be delayed until fetal maturity is achieved and a simultaneous cesarean section can be performed. However, under certain circumstances when the maternal welfare is in jeopardy the surgical intervention is mandatory even before the fetus reaches viability.

We report a rare case of pulmonary prosthetic valve endocarditis due to Aspergillus fumigatus, associated with septic pulmonary embolism and secondary pulmonary hypertension, in a 4-year-old boy with surgically corrected tetralogy of Fallot. The diagnosis and treatment of Aspergillus endocarditis remains highly challenging. The best therapeutic option for chronic thromboembolic pulmonary hypertension due to an infectious thromboembolic event is highly debatable and the results are poor.

A coronary artery fistula is a link between one or more coronary arteries with another heart cavity or a segment of systemic or pulmonary circulation. Arterial blood from a coronary vessel enters another segment via myocardial capillary bed. These are very rare anomalies which constitute approximately 0.2 - 0.4% of all congenital heart defects. Still, they are clinically significant if they are of medium or large size and are manifested with a series of clinical symptoms such as angina pectoris, arrhythmias, myocardial infarction, endocarditis, progressive dilatation, heart failure and cardiomyopathy, pulmonary hypertension, thrombosis of the fistula and formation of aneurysms with possible ruptures. We present six patients with a coronary arterial fistula, their history, diagnostic procedures and outcomes. Therapeutic closure of coronary artery fistulas is recommended in all symptomatic, but also in asymptomatic patients, if there are significant roentgenographic, electrocardiographic and other abnormalities. In recent times transcatheter closure of coronary fistulas has become a possible alternative to surgery and is becoming increasingly used thanks to improved diagnostic possibilities and technology. If possible, interventional closure of fistulas is precisely the method preferred in pediatric patients. The choice of method depends on the anatomy of the fistula, presence or absence of additional defects, and on the experience of an interventional cardiologist or a heart surgeon. If performed well, the effects of both methods are good. This paper presents two children with a fistula between the right coronary artery and the right ventricle (RV), one child with a fistula between LAD and RV, one child with a fistula between the main tree of the left coronary artery (LCA) and RV, one child with a fistula between LCA and the right ventricular outflow tract (RVOT), and one child with a fistula between LCA and the right atrium (RA). The last one (LCA-RA) is not described in the latest classification of anomalies of coronary blood vessels in children based on MSCT coronarography, so we consider our presentation to be a contribution to the new classification. Along with the descriptions of fistulas and presentations of interventional and cardiosurgical interventions, we are also presenting a rare case of spontaneous closing of the fistula within the first six months and of a reopening of the fistula between the right coronary artery and the right ventricle after six years.

An Argentine boa (Boa constrictor occidentalis) of 5 yr 7 mo of age was presented for respiratory problems and regurgitation. Radiographs revealed evidence of cardiomegaly and pneumonia. Blood smear examination revealed the presence of intracytoplasmic inclusion bodies in peripheral lymphocytes, consistent with inclusion body disease. Cultures of a tracheal wash sample resulted in growth of Ochrobactrum intermedium and Pseudomonas putida. Echocardiographic examination revealed a large vegetative lesion on the right atrioventricular valve with valvular insufficiency, a mildly dilated right atrium, and pulmonary hypertension. Postmortem examination confirmed the presence of pneumonia and bacterial endocarditis with dystrophic mineralization of the right atrioventricular valve, associated with different bacteria than those cultured from the tracheal wash. The present case is the first report of endocarditis in a boa constrictor and contributes to the rare reports of cardiac disease in snakes.
