In PVT, the thrombus size imaged with TEE is a significant independent predictor of outcome. Transesophageal echocardiography can identify low-risk groups for thrombolysis irrespective of symptom severity and is therefore recommended in the management of prosthetic valve thrombosis.

We report a case of a patient who developed acute encephalopathy following coronary angioplasty with iohexol contrast. The patient's clinical condition was associated with slowing on the EEG. Studies did not reveal any other etiology or contributing cause for the encephalopathy. The patient recovered spontaneously in 24 hours with only supportive measures. This report suggests that such a drug reaction could occur with iohexol injected in the coronaries, but reassures that the encephalopathy is self limiting.

SummaryBackground: The number of patients with congenital cardiac disease reaching adulthood is increasing steadily. Many adults with such disease face both medical and surgical difficulties.Hypothesis: This retrospective study was undertaken to assess the frequency and outcome of congenital heart disease (CHD) in unoperated adults.Methods: The charts of all patients with unoperated CHD, who were admitted to a tertiary care center in Beirut, Lebanon, between 1980 and 2000 were reviewed. Of these, 206 patients (52% men, age at admittance 18-71 years [32.8 ± 13.3 years]) with a diagnosis of CHD were evaluated. Atrial septal defect (ASD) was the most common cardiac malformation with a relative frequency of 53%, followed by ventricular septal defects (11%), tetralogy of Fallot (11%), aortic anomalies (7%), pulmonary stenosis (6%), and Ebstein anomaly (4%). Most patients were symptomatic upon presentation, with dyspnea on exertion being the most common presenting symptom. Twenty-seven patients (13%) had cyanotic CHD. Of 179 acyanotic patients, 113 (63%), and 17 of 27 cyanotic patients (63%) underwent surgical intervention. In-hospital surgical complications for the acyanotic group included cerebrovascular accident (2%) and heart block (1%). Total surgical mortality was 4 of 130 (3%). One patient with tetralogy of Fallot presented with endocarditis and died.
