Annuloplasty devices usually come in different sizes. The surgeon can estimate the dimensions of the patient’s mitral valve and decide on an appropriate ring size. Depending on the disease etiology, different approaches are taken. Surgeons can decide to "undersize" the device, "truesize" the device, or "oversize" it. [4]
Aortic valvuloplasty, also known as balloon aortic valvuloplasty (BAV), is a procedure used to improve blood flow through the aortic valve in conditions that cause aortic stenosis, or narrowing of the aortic valve. It can be performed in various patient populations including fetuses, newborns, children, adults, and pregnant women.
Treatment is not necessary in asymptomatic patients. [3] The treatment options for mitral stenosis include mitral valve replacement by surgery, and percutaneous mitral valvuloplasty by balloon catheter. [15] The indication for invasive treatment with either a mitral valve replacement or valvuloplasty is NYHA functional class III or IV symptoms.
The patient was a 12-year-old comatose girl with rheumatic mitral stenosis. [1] The development of the heart-lung machine in the 1950s paved the way for replacement of the mitral valve with an artificial valve in the 1960s. For decades after, mitral valve replacement was the
This procedure makes heart surgery possible for patients who were previously considered too high risk for traditional surgery due to age or medical history. [5] [6] Patients referred for this procedure may have coronary artery disease (CAD); aortic, mitral or tricuspid valve diseases; or previous unsuccessful stenting.
Valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). It is an alternative to valve repair.
[31] [32] It was the first aortic valve device to receive FDA approval, in November 2011 for use in inoperable patients and in October 2012 for use in patients at high surgical risk. [33] The device is effective in improving functioning in patients with severe aortic stenosis. It is now approved in more than 50 countries. [citation needed]
The patient is put on a cardiopulmonary bypass machine, also known as the heart–lung machine. This machine breathes for the patient and pumps their blood around their body while the surgeon replaces the heart valve. [citation needed] Once on cardiopulmonary bypass, the patient's heart is stopped (cardioplegia). This can be done with a Y-type ...
