Surgical treatment of giant left atrium combined with mitral valvular disease. Plication procedure for reduction of compression to the left ventricle, bronchus, and pulmonary parenchyma.

Giant left atrium associated with mitral valvular disease frequently produce postoperative problems with regard to hemodynamical and respiratory management. A new procedure of para-annular and superior plication combined with the conventional right-side plication with trimming of the left atrial wall was devised to relieve compression induced by the giant left atrium. A total of 40 patients with giant left atrium underwent operation. Ten had the valvular procedure only and 30 had the valvular and plication procedures. The plication procedure resulted in a significant decrease in the incidence of low-output syndrome and respiratory failure postoperatively, as well as a marked decrease in mortality. We conclude that the plication procedure is an effective means of relieving compression in the presence of giant left atrium.

Ventricular tachycardia in a neonate with prenatally diagnosed cardiac tumors: a case with tuberous sclerosis.

We report a patient with prenatally diagnosed tuberous sclerosis. Fetal ultrasonography demonstrated multiple cardiac tumors and arrhythmia. After birth, because of frequent supraventricular extrasystoles, the infant was admitted to the neonatal intensive care unit. Findings on 24-hour ambulatory electrocardiogram (ECG) showed frequent supraventricular tachycardia and ventricular tachycardia with four beats as the longest run. At the age of 12 days, he developed cardiopulmonary arrest after crying out. A monitored ECG showed ventricular tachycardia. Twenty minutes after onset, a 12-lead ECG showed ventricular fibrillation, which returned to normal sinus rhythm with repeated DC cardioversion. Oral antiarrhythmic therapy with carteolol hydrochloride was effective. The patient showed no further symptoms after oral medication was initiated and the tumors regressed spontaneously.

The use of intravenous immunoglobulin in Miller Fisher syndrome.

We report a patient with Miller Fisher syndrome who was treated with an intravenous high-dose of immunoglobulin. This syndrome is considered to be a benign variety of acute inflammatory demyelinating polyneuropathy (Guillain-Barré syndrome). However, there have been several reports of the need for ventilatory support and a few cases have had a fatal outcome. We observed a case of progressive Miller Fisher syndrome in a 3-year-old boy. Following 2 episodes of apnea lasting about 50 s each, he was treated with intravenous immunoglobulin (400 mg/kg/day) for 5 consecutive days. His respiratory state, general muscle strength, truncal ataxia and emotional state improved remarkably after this therapy.

New topographic mapping of temporal lobe seizures.

A unique topographic map has been developed based on EEG data of ictal events originating from the basal/mesiotemporal lobe regions. This technique involves a new mapping method of temporal lobe seizures as opposed to the interictal activity maps of most commercially available software. The map integrates data from sphenoidal electrodes as well as the standard 10-20 surface electrodes recorded with bipolar montages. A basal view is ideal for visualization of onset of temporal lobe ictal discharges recorded with chronic sphenoidal electrodes. We used the last 150 ictal events from 40 patients with basal/mediotemporal lobe epilepsy to develop this technique. Results indicate that a topographic view incorporating sphenoidal and scalp electrodes may provide a useful adjunct for interpretation of EEG recordings and a basis for comparison between and among patient groups for both ictal and interictal epileptic discharges.
