A partial anomalous pulmonary venous connection (PAPVC) is a rare congenital defect in which at least one pulmonary vein doesn't drain into the left atrium but into a systemic vein or even into the right atrium, causing a left-to right shunt. PAPVC with a small amount of shunt are usually asymptomatic, and can not be detected during lifetime. Nevertheless, if those patients undergo a major lung resection, the surgical procedure could precipitate right heart failure if this anomalous shunt remains uncorrected...

The number of patients who need cardiac support with a left ventricular assist device (LVAD) has increased over the last decade. However, the number of reports of organ retrieval from donors with an LVAD is still small. Successful lung retrieval for single lung transplantation was performed from a donor on LVAD support. This required special care not to injure the heart, great vessels, and the device, particularly the outflow conduit, because of significant conglutination around the device. A right single lung transplantation was performed successfully, with no postoperative complications...

Chronic thromboembolic pulmonary hypertension (CTEPH) should be suspected in patients presenting persistent dyspnea three months after a pulmonary embolism or in patients presenting with acute pulmonary embolism and suggestive images on the CT-scan. For these patients, a specific diagnostic work-up should be performed. First step consists of the ventilation/perfusion (V/Q) scan which is a good screening test due to its high sensitivity and high negative predictive value. Pulmonary angiography remains the gold standard approach for the confirmation of the diagnosis and pre-surgical evaluation of CTEPH...

BACKGROUND Chronic subdural hematoma (CSDH) is a common neurosurgical condition that is treated using a cranial burr hole evacuation procedure, but recurrence is common. The use of anticoagulant therapy can increase the risk of developing a recurrent subdural hematoma. We present a challenging case of a patient on long-term anticoagulant therapy following previous aortic and aortic valve surgery who had CSDH with multiple recurrences and was ultimately treated with tranexamic acid as an adjunct to surgery. CASE REPORT A male patient in his mid-sixties presented with a headache and bilateral CSDH...

BACKGROUND: Epicardial breakthrough waves (EBW) during atrial fibrillation are important elements of the arrhythmogenic substrate and result from endo-epicardial asynchrony, which also occurs to some degree during sinus rhythm (SR). We examined the incidence and characteristics of EBW during SR and its possible value in the detection of the arrhythmogenic substrate associated with atrial fibrillation. METHODS AND RESULTS: Intraoperative epicardial mapping (interelectrode distances 2 mm) of the right atrium, Bachmann's bundle, the left atrioventricular groove, and the pulmonary vein area was performed during SR in 381 patients (289 male, 67±10 years) with ischemic or valvular heart disease...

The precision of echocardiography in estimating pulmonary pressures has been debated. A value of right atrial pressure (RAP) is needed for pulmonary pressure estimation, and it could be partly responsible for the estimation error. Several schemes based on the inferior vena cava (IVC) are commonly used in clinical practice and in experimental studies for RAP estimation. However, the majority lack proper validation, and thus far, no study has compared them all. In this prospective, blinded study, a comprehensive transthoracic echocardiography was performed on 200 patients referred for right heart catheterization...

Graft dysfunction is the main cause of early mortality after heart transplantation. In cases of severe graft dysfunction, temporary mechanical circulatory support (TMCS) may be necessary. The aim of this systematic review was to examine the utilization and outcomes of TMCS in patients with graft dysfunction after heart transplantation. Electronic search was performed to identify all studies in the English literature assessing the use of TMCS for graft dysfunction. All identified articles were systematically assessed for inclusion and exclusion criteria...

Cirrhotic cardiomyopathy is associated with poor outcomes in patients with cirrhosis. We investigated if subclinical cardiac morphologic and functional modifications can influence survival in cirrhotic patients during follow-up. A series of cirrhotic patients without cardiovascular or pulmonary disease underwent standard and tissue Doppler echocardiography to assess left ventricular (LV) geometry, systo/diastolic function and the main haemodynamic parameters. After baseline evaluation 115 cirrhotic patients were followed up for at least 6 years...

BACKGROUND: Intraventricular pressure difference (IVPD), the diastolic suction during early diastole, is known as a useful marker of myocardial diastolic function in adults with different heart diseases, but there are no studies of fetal IVPD. The aim of this study was to determine whether IVPD exists and changes prenatally and whether IVPD correlates with preexisting parameters to evaluate fetal cardiac diastolic function and ventricular dominance. METHODS: Cross-sectional study data (stroke volume, fetal cardiac output, E/A ratio, and myocardial performance index) from 117 healthy fetuses at 17 to 36 weeks of gestation were retrospectively evaluated...
