Septal myectomy is associated with a low perioperative mortality and a high late survival rate. A study at the Mayo Clinic found surgical myectomy performed to relieve outflow obstruction and severe symptoms in HCM was associated with long-term survival equivalent to that of the general population, and superior to obstructive HCM without operation.
Alcohol septal ablation was first performed in 1994 by Ulrich Sigwart at the Royal Brompton Hospital in the United Kingdom. [2] Since that time, it has gained favor among physicians and patients due to its minimally invasive nature, thereby avoiding general anesthesia, lengthy inpatient recuperation and other complications associated with open-heart surgery (e.g. septal myectomy).
This is a catheter technique with results similar to the surgical septal myectomy procedure but is less invasive, since it does not involve general anaesthesia and opening of the chest wall and pericardium (which are done in a septal myectomy). In a select population with symptoms secondary to a high outflow tract gradient, alcohol septal ...
Significant complications of the operation include bleeding, heart problems (heart attack, arrhythmias), stroke, infections (often pneumonia) and injury to the kidneys. Three coronary artery bypass grafts, a pedicled LITA to LAD and two saphenous vein grafts – one to the right coronary artery system and one to the obtuse marginal system.
Off-pump coronary artery bypass was developed partly to avoid the complications of cardiopulmonary bypass during cardiac surgery. It had been believed that cardiopulmonary bypass causes a post-operative cognitive decline known as a postperfusion syndrome (informally called "pumphead"), but research has shown no long-term difference between on ...
Minimally invasive direct coronary artery bypass (MIDCAB) is a surgical treatment for coronary heart disease that is a less invasive method of coronary artery bypass surgery (CABG). [1]
Some potential complications associated with the procedure include: [18] Bleeding - catheter insertion into arteries or veins can cause bleeding at the insertion site. Blood vessel damage - insertion of the catheter can also damage the blood vessels and lead to hematoma, which is a collection of blood outside the blood vessels, or vessel ...
The Amplatzer device from St. Jude Medical, used to close atrial septal defects, has also been used to occlude the left atrial appendage. [21] [22] This can be performed without general anaesthesia and without echocardiographic guidance. Transcatheter patch obliteration of the LAA has also been reported. [15]
