RESUMO
A patient with severe Parkinson's disease experienced a syncopal attack due to skeletal muscle myopotential inhibition of an implanted ventricular demand pacemaker. The problem was diagnosed with the aid of Holter monitoring, and was corrected by noninvasively programming the pacemaker to a lower sensitivity.

The findings in a patient with atrial flutter whose audible atrial sounds uniquely modulated an aortic regurgitant murmur are presented, with phonocardiographic and echocardiographic correlates, which suggest a ventricular origin for these sounds.

A 30-year-old man with a history of a murmur since childhood had progressive ascites for 2 years. The patient was found to have severe stenoses of the pulmonic and tricuspid valves with a well-developed right ventricle. Impressive clinical improvement occurred after pulmonic valvotomy, infundibulectomy, and replacement of the stenotic tricuspid valve with a porcine xenograft. The clinical, echocardiographic, hemodynamic, surgical, and pathological features are presented.

Two patients, catheterized primarily for the preoperative assessment of clinically apparent aortic stenosis and insufficiency, were found to have a patent ductus arteriosus as well at cardiac catheterization. The association of aortic valve disease and patent ductus arteriosus is reviewed, and the importance of making the diagnosis prior to aortic valve replacement is stressed, emphasizing the routine use of the hydrogenplatinum electrode system.
