Patients
The following were the characteristics of the patients from Brazil. Due to local circumstances, Brazilian patients only gave oral consent. They were mostly from a low socioeconomic class and had traveled long distances from the interior of the South American country to receive medical care. Cardiac transplantation and other forms of cardiac assist support, such as intraaortic balloon pumping and left ventricular (LV) assist devices, were not available at the Hospital Angelina Caron. It was
Results
The patients from both institutions ranged in age from 11 to 74 years (mean, 53.0 ± 12.0 years). There were 97 male and 23 female patients. All patients were in New York Heart Association (NYHA) functional class IV, and 30% required hemodynamic support at the time of the operation. All patients had an ejection fraction less than 0.20. Dilated (viral or idiopathic) cardiomyopathy with or without valvular involvement was the primary indication for operation in Buffalo, whereas ischemic,
Comment
We began performing partial left ventriculectomy in Brazil to treat patients with dilated cardiomyopathy of varying causes because we reasoned [1]that cardiac performance could be improved by reducing LV diameter (cardioreduction). Observations of hearts in different mammalian species, including humans, suggested that heart mass is proportional to body weight. Heart mass and radius are also related. An increase in radius leads to an increase in mass to maintain this normal relationship. When
