A heart stent procedure usually takes 1 to 3 hours, depending on the patient’s condition and the proficiency of the operator. Patients with complex and serious conditions may take longer, and the exact time cannot be generalized.
Cardiac stenting begins with local anesthesia and puncture of the radial or femoral arteries, followed by coronary angiography to clarify the narrowing of the coronary arteries and to identify the arterial vessels that need to be stented.
Some vessels with mild lesions can be easily opened and stenting is easy and may take an hour, or less, and the procedure may be completed quickly. Some vessels with more serious lesions, such as occlusive lesions and severely calcified lesions, are more difficult to unblock, and situations such as resuscitation during the operation may take three hours, or even longer, so the operation will take longer.
If some lesions can not be unblocked blood vessels, or too many lesions can not be stented, etc., then it may be necessary to do heart bypass surgery.
It is recommended that patients consult a professional cardiovascular internal medicine department in time to avoid delaying the condition and affecting the treatment.
