BACKGROUND AND AIM OF THE STUDY The study aim was to evaluate the Freedom SOLO pericardial stentless valve prosthesis implanted in a subcoronary or supra-annular position, using a single running suture, over a follow up period of up to five years. The clinical data obtained after aortic valve replacement (AVR) were analyzed retrospectively for validation.(More)
The Takotsubo cardiomyopathy (TTC), also called ‘‘stress cardiomyopathy’’, ‘‘transient apical ballooning’’ or ‘‘broken heart syndrome’’, is a disorder associated with transient left-ventricular dysfunction in absence of substantial coronary artery disease. The clinical presentation is similar to an acute coronary syndrome with acute chest pain and dyspnea(More)
Sirs: Coronary artery fistulas are anomalous connections between a coronary artery and a cardiac chamber or great vessel [1]. They are rare abnormalities with a reported incidence of 0.13–0.18% of patients undergoing coronary angiography [2, 3]. The majority of coronary artery fistulas are congenital in origin, but they have been reported as acquired(More)
A 40-year-old male presented with exertional dyspnea and peripheral edema despite intensive medical treatment. The patient had suffered from rheumatic fever 13 years ago, a severe aortic valve stenosis led to mechanical valve replacement 6 years ago. Now, echocardiography revealed a severe stenosis of the tricuspid valve with a mean diastolic pressure(More)
OBJECTIVES The authors sought to analyze height differences within the coronary artery tree in patients in a supine position and to quantify the impact of hydrostatic pressure on intracoronary pressure measurements in vitro. BACKGROUND Although pressure equalization of the pressure sensor and the systemic pressure at the catheter tip is mandatory in(More)
We report the case of a 39-year-old male with a history of untreated arterial hypertension. He presented to a community hospital with pulmonary edema and anasarca, and was transferred to our heart center for further investigation and therapy. Echocardiography revealed the enlargement of all four heart chambers including a severely compromised systolic(More)
We report the case of a 69-year-old man with a history of 2,3diphosphoglycerate deficiency and consecutive splenectomy due to hemolytic anemia. He presented in emergency room following a sudden onset of severe pain in the right upper abdomen and mild dyspnea. One week before, he had suffered short-lasting chest pain after cycling. There was no history of(More)
Looking after children means caring for very small infants up to adult-sized adolescents, with weights ranging from 500 g to more than 100 kg and heights ranging from 25 to more than 200 cm. The available echocardiographic reference data were drawn from a small sample, which did not include preterm infants. Most authors have used body weight or body surface(More)
