Surgical treatment of right ventricular aneurysm: an uncommon procedure.
Most ventricular aneurysms result from transmural myocardial infarction and are located in the left ventricle. Right ventricular aneurysms are unusual, and their origin at times is obscure. A patient with two discrete right ventricular aneurysms is reported. The literature on operative excision of right ventricular aneurysms is reviewed, and the various etiological factors are discussed.

Bilateral consecutive superior oblique palsy following fronto-ethmoidal sinusitis.
A 61-year-old woman developed a left superior oblique palsy as a result of frontoethmoidal sinusitis. After stabilization, the left inferior oblique and right inferior rectus were recessed. Three years later, she developed a right superior oblique palsy associated with fronto-ethmoiditis. The right inferior oblique and left inferior rectus were recessed.

Premature ventricular contractions: Which ones require treatment?
Treatment of ventricular arrhythmias remains a difficult problem owing to our lack of understanding of etiology, prognosis, and efficacy of various antiarrhythmic agents. Lidocaine appears to prevent ventricular fibrillation during the CCU of myocardial infarction. Warning arrhythmias seen in the CCU do not in actuality accurately warn the clinician of risk of fibrillation. Secondary prevention of sudden death following infarction with antiarrhythmic agents may be of some value. There is little to suggest that drugs available in the United States are efficacious for this use. For the most part, treatment of outpatients with ventricular arrhythmias probably should be confined to those patients with symptomatic arrhythmias or to patients with complex ventricular arrhythmias and other objective evidence of cardiac disease.
