Two hundred adults who underwent surgery for congenital heart disease at our institution within a four year period were the basis for this report. Clinical data was obtained, i.e. demographic details, past medical history, physical findings, EKGs, echocardiograms, catheterization and angiography material as well as the New York Heart Association (NYHA) class. Intraoperative findings, perioperative management, complications and morbidity and mortality were assessed. After discharge the patients were followed on an outpatient basis. Again the clinical findings, laboratory results and NYHA class were recorded. Age ranged from 16 to 75 years (mean = 38). There were 114 females and 86 males. 178 patients had primary surgical correction, 18 were reoperated after prior correction and 4 underwent palliation. Eighty-three percent of the patients were symptomatic preoperatively. Seventeen percent were diagnosed per chance, for example by a preemployment physical examination, without a prior history of heart disease. The patients were grouped according to related diagnoses (Table 1). Among the 130 patients with left to right shunts, 112 had an atrial septal defect, 7 a ventricular septal defect, 5 a persistent ductus arteriosus, and 6 partial anomalous pulmonary venous return. Atrial flutter or fibrillation occurred in approximately 10% of all patients with atrial septal defects. It was terminated either by rapid overdrive pacing or DC cardioversion. Postoperatively the patients with pulmonary hypertension were monitored invasively with arterial lines and thermodilution catheters. Therapy consisted of alkalization, hyperventilation and sedation. There was only one postoperative death in this patient group due to marked pulmonary hypertension (1/130 = 0.8%). Nineteen adults had obstruction to right or left ventricular outflow. Surgery included valvotomy, infundibulectomy and valve replacement by homograft or mechanical valve. One patient with multiple previous surgeries expired due to bleeding (3%). Thirteen patients had coarctation. All of them were hypertensive, some on medication. Surgery consisted of aortic patchplasty or interposition of a graft. There was no mortality. Perioperative antihypertensive therapy was necessary in most patients and consisted of nifedipin, nitroprussid or propanolol intravenously. Upon follow up 11 patients became normotensive, 8 of these without the need for medication. Fifteen cyanotic patients underwent 11 corrective and 4 shunt procedures (3 with tricuspid atresia, 10 with Tetralogy of Fallot and 2 with complex cyanotic heart disease. Three died due to low cardiac output or dysrhythmias (20%). The survivors improved their clinical status markedly. Seven adults with Ebstein's disease had valve reconstruction and/or ASD closure. Five had recurrent supraventricular tachycardia, 2 paradoxical emboli with neurological symptoms and 4 out of 7 had decreased exercise tolerance. One patient died postoperatively because of dysrhythmias (14%). Sixteen patients had a variety of defects, i.e. status post Rastelli operation and conduit obstruction, status post Tetralogy of Fallot with pulmonary valvar disease, corrected transposition with left AV valve insufficiency, congenital mitral valve disease and double aortic arch, no deaths. The overall operative mortality was 6/200 = 3%. the late mortality was 4/200 = 2%. The morbidity included 7 reoperations due to bleeding. Five patients needed short-term hemodialysis. One patient developed hemiplegia and two patients had permanent decrease of their left ventricular function. The mean length of follow up was 21 months. The clinical status improved from a NYHA class mean of 2.1 +/- 0.9 to 1.2 +/- 0.45 (p < 0.001). In Germany significant numbers of adults with operated and unoperated congenital heart disease do exist. Detection of these patients can be difficult due to inconspicuous murmurs or stable clinical status.

The case of a patient affected with acute pulmonary embolism and concomitant cerebral thromboembolism is described. The patient was admitted to our Coronary Care Unit with aphasia and hemiplegia. Five days before, he had undergone a hip replacement. A lung scan showed bilateral embolism; transthoracic echocardiogram revealed signs of pulmonary hypertension and the presence of a large, elongated, highly mobile "in-transit" thrombus entrapped into a patent foramen ovalis, and prolapsing into the right and left ventricle during diastole. The patient underwent surgical removal of the thrombus, with closure of the patent foramen. We did not treat the patient with thrombolysis, fearing the damage that a new embolism might produce. After surgery, the patient had a lengthy hospital stay because of renal failure and infection due to Pseudomonas aeruginosa. The patient was discharged from the hospital three months later on dialytic treatment and although he was still aphasic, there was partial recovery of motor function. Nevertheless, normalization of renal function and regression of aphasia occurred during the following months, with a residual mild motor defect of the right hand. This case report represents a starting point for discussing treatment of "in-transit" thrombi during pulmonary embolism.

Between 1.6.1991 and 31.5.1995, 62 patients underwent heart valve replacement with Sorin Bicarbon bileaflet prosthetic valve, age 16-83 years (mean 60.5). The valve disease was rheumatic in 37 cases, degenerative in 17, congenital in 4 and miscellaneous etiologies in the other 4. The valve lesion was AS in 24 patients, AR in 5, AR+MS in 2, MS in 13, MR+MS in 6, MR in 6, tricuspid prosthetic stenosis in 1, A+M disease in 3, and a clotted prosthetic valve (Sorin disc) in 1. CAD was present in 14 patients (23%) and AF in 19 (31%). 11 had moderate pulmonary hypertension and 4 severe. Preoperatively 6 patients were in FC II, 40 in FC III and 16 in FC IV. Operative procedures included AVR 18, AVR+CABG 13, AVR+T annuloplasty 1, AVR and open M valvotomy 1, MVR 7, MVR+T annuloplasty 7, MVR+AVR (Medtronic) 1, MVR+AVR 1, TVR, prosthetic valve replacement 1, and MVR+CABG 1. Hospital mortality was 3 (4.8%) -- one due to ruptured A-V groove and two due to LoCO. Postoperative complications: LoCO necessitating IABP -- 3 patient; 3 transient CVA and 1 CVA with hemiplegia. One patient had aortic prosthetic valve endocarditis 18 months following the operation necessitating reoperation. Other cases were treated for positive blood cultures. One patient had CVA after anticoagulant were discontinued. 28 patients are in FC I, 22 in H, 4 in III and 1 in IV. 4 patients are lost to follow-up. These data suggest that the Sorin Bicarbon Prosthetic valve can be safely and effectively used for heart valve replacement.

A 56-year-old woman with right hemiplegia for recent cerebral bleeding suddenly complained of dyspnea and chest pain with hypoxia during rehabilitation. Eight days after this first attack, she suffered prolonged right heart failure and hypoxia due to recurrent pulmonary embolism. Arterial blood gas analysis of room air showed 34.5 mmHg of PaO2 and 29.2 mmHg of PaCO2. Echocardiography showed enlargement of the right atrium and ventricle with pulmonary hypertension. Enhanced chest computed tomography revealed pulmonary emboli from the main pulmonary artery to the periphery. Despite intensive treatment, heart failure and hypoxia did not improve. We conducted pulmonary embolectomy under cardiopulmonary bypass requiring percutaneous cardiopulmonary bypass support for 2 days due to right heart failure. She is currently doing well in the 9 months following surgery.

A 28-year-old man presented with transient speech disturbance and right hemiplegia. Computed tomography of the brain revealed a low-density area in the right cerebellum. A ventilation/perfusion lung scintiscan detected multiple perfusion defects in the both lungs and catheterization revealed pulmonary hypertension. Venography of the upper extremities revealed obstruction of the left subclavian vein. Furthermore, Doppler echocardiography revealed a right-to-left shunt via a patent foramen ovale. Those examinations demonstrated paradoxical cerebral embolism caused by Paget-Schroetter syndrome, which is a rare complication of the disorder. We hypothesize that the source of thrombi was the left subclavian vein and surgery was needed to prevent further thromboembolic events. At surgery, the upper half of the sternum was incised in the midline, and the left brachiocephalic vein was ligated. No thromboembolic episodes have occurred postoperatively.

An 87-year-old woman was admitted to our Cardiology Department with symptoms and signs of acute congestive heart failure and fever. She had a long history of hypertension and chronic atrial fibrillation. Transthoracic echocardiography showed a large (>10 mm) and mobile mitral valve vegetation, prolapsing into the left ventricular inflow tract, with severe mitral regurgitation due to a perforation in the posterior leaflet, in a mitral valve with fibro-calcific degeneration. Mitral regurgitation was hemodynamically significant and a moderate-to-severe pulmonary hypertension was observed. Tissue Doppler Imaging recorded at the level of the vegetation detected its incoherent motion and measured the peak antegrade velocity, which was found to be almost four times higher than that sampled at the lateral mitral annulus. Blood cultures were negative for both aerobic and anaerobic microbes. During hospitalization, the patient developed a sudden onset of left-side hemiplegia. Diffusion-weighted magnetic resonance imaging demonstrated multiple hyperintense lesions involving both hemispheres, suggestive of a cardioembolism. Diagnosis of fungal endocarditis was made and a treatment with fluconazole was started. Successive echocardiograms showed a decrease in the size and mobility of the mitral vegetation, and an increase in its echo intensity. However, in view of the systemic conditions severely affected, the patient was treated conservatively and died 3 months later. In our patient echocardiography played a key role for a better definition of the clinical course. In this context, Tissue Doppler Imaging might provide an adjunctive parameter for the prediction of embolic risk from endocardial vegetations: the peak antegrade velocity recorded at the level of the vegetation. However, before being adopted in clinical setting, this parameter should be validated by adequately powered prospective studies.

Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by chronic thrombi in the pulmonary arteries, causing pulmonary hypertension and right heart failure. Early and accurate diagnosis are essential for successful treatment but are often difficult because clinical signs and symptoms can be nonspecific and risk factors, such as history of venous thromboembolism, may not always be present. Here, we report a case involving a 76-year-old woman who demonstrated paradoxical cerebral embolism as the initial manifestation of CTEPH. She developed right hemiplegia without dyspnea or edema. Brain magnetic resonance imaging revealed multiple fresh infarctions, while transesophageal echocardiography revealed a patent foramen ovale. Based on these findings, she was diagnosed as having paradoxical cerebral embolism. During the search for the embolic source, right heart catheterization showed significant pulmonary hypertension and pulmonary angiography revealed chronic thrombi in the peripheral pulmonary arteries, consistent with a diagnosis of CTEPH. To our knowledge, this is the first case of CTEPH to be diagnosed with the onset of paradoxical cerebral embolism. Because CTEPH is the only potentially curable form of pulmonary hypertension, clinicians should consider paradoxical cerebral embolism as a possible initial manifestation of CTEPH.
