ABSTRACT

The use of radial artery grafts for coronary bypass surgery is becoming more frequent. However, experience with percutaneous coronary intervention for radial artery graft failure is limited. We describe a patient with a radial artery graft in whom angina reappeared because of de novo stenosis in the graft. The patient was successfully treated with balloon angioplasty and stenting. At 6 months he again had angina due to a second de novo stenosis of the radial artery graft, which was also treated with angioplasty. At follow-up the patient remained asymptomatic with no evidence of ischemia.

ABSTRACT

La utilización de la arteria radial como injerto arterial en la cirugía de revascularización coronaria es cada vez más frecuente. Hay escasa experiencia sobre intervencionismo coronario percutáneo en este tipo de injerto arterial. Presentamos el caso de un paciente con injerto de arteria radial en el que la reaparición de la sintomatología anginosa se relacionó con la presencia de una estenosis de novo en dicho injerto. Este paciente fue tratado satisfactoriamente mediante angioplastia con balón e implantación de stent. A los 6 meses presentó angina por una segunda estenosis de novo del injerto radial, también abordada con angioplastia. En el seguimiento, el enfermo se mantuvo asintomático y sin evidencia de isquemia

ABSTRACT

PURPOSE: We investigated the prevalence and clinical importance of cardiovascular abnormalities in patients with hyperthyroidism. METHODS: All consecutive patients diagnosed with hyperthyroidism during a period of 24 months were included in the study. Medical history, complete physical examination results, electrocardiographic findings, laboratory determinations, and Doppler echocardiographic findings were obtained for all patients within 24 hours of diagnosis, and after euthyroidism had been achieved. Age- and sex-matched controls also were studied. RESULTS: Thirty-nine patients (mean [+/-SD] age, 52 +/- 20 years; range, 25 to 86 years; 72% women), and 39 age- and sex-matched controls, were included. Atrial fibrillation was present in 7 patients (18%). Moderate or severe mitral or tricuspid regurgitation, or both, were present in 9 patients (23%) and in only 1 control (3%; P= 0.01). Mean pulmonary arterial systolic pressure was 38 +/- 12 mm Hg (range, 17 to 64 mm Hg) in patients and 27 +/- 4 mm Hg (range, 19 to 37 mm Hg) in controls (P= 0.001). Sixteen patients (41%) and 1 control (3%) had pulmonary arterial systolic pressure >or=35 mm Hg. Left ventricular systolic dysfunction was detected in 1 patient. After correction of hyperthyroidism, a significant decrease in pulmonary arterial systolic pressure was observed, and the levels became similar to those of controls. CONCLUSION: In patients with hyperthyroidism, there is a high prevalence of pulmonary hypertension and atrioventricular valve regurgitation. These abnormalities usually correct after treatment for hyperthyroidism.
