Aortic valve repair
Aortic valve repair or aortic valve reconstruction describes the reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of an aortic aneurysm, less frequently for congenital aortic stenosis. Aortic valve replacement
In adults, symptomatic severe aortic stenosis usually requires aortic valve replacement (AVR). While Surgical AVR has remained the most effective treatment for this disease process and is currently recommended for patients after the onset of symptoms, as of 2016 aortic valve replacement approaches included open-heart surgery, minimally invasive cardiac surgery (MICS), and minimally invasive catheter-based (percutaneous) aortic valve replacement. However, surgical aortic valve replacement is well-studied, and generally has a good and well-established longer-term prognosis.A diseased aortic valve is most commonly replaced using a surgical procedure with either a mechanical or a tissue valve. The procedure is done either in an open-heart surgical procedure or, in a smaller but growing number of cases, a minimally invasive cardiac surgery (MICS) procedure. Minimally invasive approach via right minithoracotomy is most beneficial in the high risk patient such as the elderly, the obese, those with chronic obstructive pulmonary, chronic kidney disease and those requiring re-operative surgery. Transcatheter aortic valve replacement
Globally more than 250,000 people have received transcatheter aortic valve intervention (TAVI). For people who are not candidates for surgical valve replacement and most patients who are older than 75, TAVI may be a suitable alternative.
Use in executions
The drug has been introduced for use in executions by lethal injection in certain jurisdictions in the United States in combination with other drugs. It was introduced to replace pentobarbital after the latters manufacturer disallowed that drugs use for executions. Midazolam acts as a sedative but will fail to render the condemned prisoner unconscious, at which time vecuronium bromide and potassium chloride are administered, stopping the prisoners breathing and heart, respectively. Since the condemned prisoner is not unconscious but merely sedated, two very different things, those following two drugs can cause extreme pain and panic in the soon to die prisoner.Midazolam has been used as part of a three-drug cocktail, with vecuronium bromide and potassium chloride in Florida and Oklahoma prisons. Midazolam has also been used along with hydromorphone in a two-drug protocol in Ohio and Arizona.The usage of midazolam in executions became controversial after condemned inmate Clayton Lockett apparently regained consciousness and started speaking midway through his 2014  execution when the state of Oklahoma attempted to execute him with an untested three-drug lethal injection combination using 100 mg of midazolam. Prison officials reportedly discussed taking him to a hospital before he was pronounced dead of a heart attack 40 minutes after the execution began. An observing doctor stated that Locketts vein had ruptured.
