The Rastelli procedure is an open heart surgical procedure developed by Italian physician and cardiac surgery researcher, Giancarlo Rastelli, in 1967 at the Mayo Clinic, and involves using a pulmonary or aortic homograft conduit to relieve pulmonary obstruction in double outlet right ventricle with pulmonary stenosis.
Cardiac surgery, or cardiovascular surgery, is a surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...
Four incisions for an appendectomy, corresponding to the order listed. Hasson Entry: The two red lines mark the sites of the 5mm laparoscopic ports. The blue line above the umbilicus marks the site of the camera port Surgeons perform a laparoscopic appendectomy. In general terms, the procedure for an open appendectomy is:
The Fontan Kreutzer procedure is used in pediatric patients who possess only a single functional ventricle, either due to lack of a heart valve (e.g. tricuspid or mitral atresia), an abnormality of the pumping ability of the heart (e.g. hypoplastic left heart syndrome or hypoplastic right heart syndrome), or a complex congenital heart disease where a bi-ventricular repair is impossible or ...
Norwood procedure is most commonly performed to treat hypoplastic left heart syndrome, double outlet right ventricle, double inlet left ventricle, and other single ventricle congenital heart defects. [5] Variations are also used for palliation of mitral and tricuspid atresia [6] and subsets of transposition of great arteries (TGA). [7]
The surgeon then connects the separated parts of the aorta together. The surgeon then transects the pulmonary artery and aorta and frees them from surrounding tissue, then makes an incision into the right ventricle to allow them to assess the ventricular septal defect and remove excess muscle bundles in cases of extensive right ventricular ...
A ventriculotomy is a heart surgery that involves an incision into one or both ventricles. It is a component of many heart surgeries, including infarctectomy and many congenital heart defect surgeries. In the long-term, a prior ventriculotomy can increase the risk of ventricular arrhythmia. Right ventriculotomy often causes right bundle branch ...
The papillary muscles of both the right and left ventricles begin to contract shortly before ventricular systole and maintain tension throughout. [1] This prevents regurgitation—backward flow of ventricular blood into the atrial cavities—by bracing the atrioventricular valves against prolapse—being forced back into the atria by the high ...
