Cardiovascular alterations such as increased heart rate, high cardiac output, reduced systemic vascular resistance, and in most of the cases, increased contractility parameters have been recognized in patients with advanced liver disease. Some investigators define a cirrhotic cardiomyopathy as a hyperdynamic failure of the heart. Consequently, in patients with cirrhosis, ...
Aoki N - - 1988
Two cases of infantile hydrocephalus are reported, in which the ventricular shunt proved to function despite the catheter tip being located outside the ventricular system, as revealed by computed tomography. This condition could be erroneously diagnosed as arrested hydrocephalus or proximal shunt malfunction, with a resultant potential risk of inadequately ...
Brecker S J - - 1988
Coronary artery aneurysms developed in a 43 year old man who had suffered an acute myocardial infarction at the age of 30. In childhood he had had an illness that was consistent with Kawasaki disease, and it is suggested that the proximal discrete aneurysms and myocardial infarction may be the ...
Otto C M - - 1988
Both echocardiography and radionuclide angiography have been proposed as noninvasive modalities for the diagnosis of left ventricular pseudoaneurysm. In the only three cases seen at our institution over the past five years, this diagnosis was missed with radionuclide blood pool imaging, while two-dimensional echocardiography demonstrated the typical features of a ...
Jain A - - 1988
Left ventricular aneurysm is a common sequela of anterior myocardial infarction. At the time of coronary artery bypass grafting, resection of this aneurysm is frequently undertaken to alleviate symptoms of heart failure and/or refractory ventricular tachycardia. Complications related to aneurysmectomy are uncommon. We describe an unusual patient who presented with ...
Hasegawa K - - 1988
Two patients with extensive anterior myocardial infarction developed a hitherto unreported type of right ventricular outflow tract obstruction. A 71-year-old woman, who had had an acute infarction 10 years before, was admitted for sustained ventricular tachycardia. A loud ejection murmur was heard in the mid-precordium. The echocardiogram and left ventriculogram ...
Walker W S - - 1988
Because little information is available concerning the outcome of surgery for left ventricular aneurysm when multiple concurrent coronary grafts are required, we have reviewed 35 consecutive patients undergoing aneurysm surgery and multiple (greater than or equal to 3) grafts between December 1973 and April 1984. There were 6 operative deaths ...

Pseudoaneurysm is an unusual complication of myocardial infarction. Although its pathogenesis is known, the course of the condition is obscure. The diagnosis is usually made post-mortally. We present a case of a pseudoaneurysm following a myocardial infarction, diagnosed at a routine polyclinical echocardiographic examination in a patient who at the ...
Hiro T - - 1988
A 54-year-old man presented with continual angina pectoris at rest, associated with an anomalous coronary artery. He also had an aneurysm at the submitral region of the left ventricular postero-lateral wall, without evidence or prior myocardial infarction, which showed hypokinetic inward motion during systole. We assume that this was a ...
Doi Y L - - 1987
A 17-year-old asymptomatic boy with a history of Kawasaki disease in infancy was found to have an abnormal ring-calcification as seen in the chest roentgenogram and the electrocardiographic evidence of anteroseptal myocardial infarction. Coronary angiogram revealed aneurysms associated with ring-calcifications in the right coronary artery and subtotal obstruction of the ...
Swanson M J - - 1987
In the case reported, a patient with severe right ventricular failure following coronary revascularization was successfully weaned from cardiopulmonary bypass following creation of an atrial septal defect. This technique facilitated rapid decompression of the failing right ventricle by shunting blood to the more compliant left ventricle, thus augmenting left ventricular ...
Magovern G J - - 1987
Two patients are described, each with a large left ventricular aneurysm and severe coronary artery disease, and each with an ejection fraction lower than 30% and in congestive heart failure. In both, the left latissimus dorsi (LD) muscle was used in the repair of the ventricular aneurysm because preoperative studies ...
Louagie Y - - 1987
From 1979 to 1985, 109 patients were treated for congestive heart failure caused by postinfarction left ventricular aneurysm. Congestive heart failure was predominant in all patients at the time of diagnosis, 73% of whom were in Functional Class III or IV. Left ventricular end-diastolic pressure averaged 23.8 +/- 0.8 mm ...
McCriskin J W - - 1987
Left ventricular pseudoaneurysm complicating myocardial infarction is extremely rare. A case of left ventricular anterolateral pseudoaneurysm with its initial presentation mimicking septic shock is reported. The need for urgent resection is stressed due to the high incidence of spontaneous rupture and death regardless of the age or the size of ...
Kupari M - - 1987
The development of a left ventricular pseudoaneurysm is a rare complication of heart surgery. Until recently it has been impossible to detect without an angiographic study of the left ventricle. A combination of cross sectional and Doppler ultrasound studies led to the correct diagnosis in two patients with left ventricular ...
Zhou T F - - 1987
In a 1 year period, 56 neonates with a clinical diagnosis of ductus arteriosus had Doppler echocardiographic confirmation of the ductus; 33 (59%) had additional, turbulent left to right flow at the atrial level through a valve-incompetent foramen ovale. Normalized left atrial dimensions in the group with the atrial shunt ...
Ginsberg F - - 1987
Three cases of cardiac pseudoaneurysms were presented, with findings at the time of gated blood pool imaging.
