Question: In what city was the Rastelli procedure was developed?

Context paragraphs:
Berlin procedure: The so-called Berlin procedure (BV) is a mathematical procedure for time series decomposition and seasonal adjustment of monthly and quarterly economic time series.  The mathematical foundations of the procedure were developed in 1960's at the Technical University of Berlin and the German Institute for Economic Research (DIW).  The most important user of the procedure is the Federal Statistical Office of Germany.

Giancarlo Rastelli: Giancarlo Rastelli (1934–1970) was a cardiac surgeon.  He was the creator of the Rastelli procedure.  He died of cancer at just 36 years of age.  At the time of his death he was the head of cardiovascular surgical research at the Mayo Clinic, in Rochester, MN.  He has been suggested for sainthood by the Catholic Church, and his cause is currently in a waiting and prayer period.

Procedure word: Procedure words or prowords are words or phrases limited to radio telephone procedure used to facilitate communication by conveying information in a condensed standard verbal format.  Prowords are voice versions of the much older prosigns for Morse code first developed in the 1860s for Morse telegraphy, and their meaning is identical.  The U.S. military communications manual ACP-125 is the most formal and perhaps earliest modern (post-WW-II) definitions of procedure words), but its definitions have been replicated by many other organizations, including the United Nations Development Programme, , the U.S. Coast Guard, the Rhode Island Department of Emergency Management, Civil Air Patrol, Military Auxiliary Radio System, and others.

Gum lift: A gum lift is a cosmetic dental procedure that raises and sculpts the gum line.  This procedure involves reshaping the tissue and/or underlying bones to create the appearance of longer or symmetrical teeth, thereby making the smile more aesthetically pleasing.  This procedure is typically done to reduce excessively gummy smiles or to balance out an asymmetrical gum line.  The procedure, also known as crown-lengthening, has historically been used to treat gum disease.  It is only within the past three to five years that dentists have commonly used this procedure for aesthetic purposes.  The practice of cosmetic gum lifts was first developed in the late 1980s, but there were few oral surgeons and dental practitioners available to perform the procedures.  Gum lifts can also include bone shaping to reduce the prominence of the upper jaw and even out the tooth and gum ratio.  This method provides permanent results, while simple gum contouring may result in relapse or regrowth of the gingiva.

Rastelli procedure: 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

Mayo Clinic: The Mayo Clinic is a nonprofit medical practice and medical research group based in Rochester, Minnesota.  It employs more than 4,500 physicians and scientists and 57,100 allied health staff.  The practice specializes in treating difficult cases through tertiary care.  It spends over $660 million a year on research.

Epidural lysis of adhesions: Epidural lysis of adhesions (LOA), also known as the Racz procedure, is an interventional technique which involves the dissolution of epidural scar tissue by mechanical means to facilitate the spread of analgesics in an effort to alleviate pain.  It is a minimally invasive medical procedure developed at Texas Tech University Health Sciences Center (TTUHSC) in 1989 by Gabor B. Racz.  It is a type of percutaneous adhesiolysis procedure commonly used to treat chronic pain resulting from failed back surgery syndrome wherein scar tissue has formed around the nerves and causes pain.  Evidence suggests the procedure may also be effective in treating spinal stenosis and radicular pain caused by a herniated disc.

Helen B. Taussig: Helen Brooke Taussig (May 24, 1898 – May 20, 1986) was an American cardiologist, working in Baltimore and Boston who founded the field of pediatric cardiology.  Notably, she is credited with developing the concept for a procedure that would extend the lives of children born with Tetralogy of Fallot (the most common cause of blue baby syndrome).  This concept was applied in practice as a procedure known as the Blalock-Taussig shunt.  The procedure was developed by Alfred Blalock and Vivien Thomas, who were Taussig's colleagues at the Johns Hopkins Hospital.

Welding Procedure Specification: A Welding Procedure Specification (WPS) is the formal written document describing welding procedures, which provides direction to the welder or welding operators for making sound and quality production welds as per the code requirements .  The purpose of the document is to guide welders to the accepted procedures so that repeatable and trusted welding techniques are used.  A WPS is developed for each material alloy and for each welding type used.  Specific codes and/or engineering societies are often the driving force behind the development of a company's WPS.  A WPS is supported by a Procedure Qualification Record (PQR or WPQR).  A PQR is a record of a test weld performed and tested (more rigorously) to ensure that the procedure will produce a good weld.  Individual welders are certified with a qualification test documented in a Welder Qualification Test Record (WQTR) that shows they have the understanding and demonstrated ability to work within the specified WPS.

Colposcopy: Colposcopy (Ancient Greek: κόλπος  "kolpos"  "hollow, womb, vagina" + "skopos" "look at") is a medical diagnostic procedure to examine an illuminated, magnified view of the cervix and the tissues of the vagina and vulva.  Many premalignant lesions and malignant lesions in these areas have discernible characteristics which can be detected through the examination.  It is done using a colposcope, which provides an enlarged view of the areas, allowing the colposcopist to visually distinguish normal from abnormal appearing tissue and take directed biopsies for further pathological examination.  The main goal of colposcopy is to prevent cervical cancer by detecting precancerous lesions early and treating them.  The procedure was developed by the German physician Hans Hinselmann, with help from Eduard Wirths.  The procedure involved female Jewish inmates from Auschwitz.
