Male patients were more likely to have smoking, coronary heart disease, cardiomyopathy, chronic obstructive pulmonary disease and coronary artery bypass grafting histories, while female patients had more hypertension and atrial fibrillation. The average age and left ventricular ejection fraction were significantly lower in men than in women (p&lt;0.001), while the intervention rate (p=0.026) and total hospitalisation cost (p=0.016) of male patients were higher than those of female patients. There were no significant differences in perioperative complications, in-hospital outcomes or short and intermediate prognoses between the two groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Currently, the intervention rate of elderly patients with VHD is still not ideal, with dominant factor\u2014patient rejection.
