Here, we demonstrate the details of annular decalcification using an ultrasonic aspirator in minimally invasive aortic valve replacement for aortic stenosis. In our debridement procedure, the aortic valve leaflets are excised with enough valve tissue left, not just at the annulus. The invisible annulus is exposed by traction of the remnant valve tissue, and the annular calcifications are scraped off using an ultrasonic aspirator. After an annular decalcification, the remnant valve tissue was completely resected using long scissors. No cases of in-hospital mortality, annular injury, stroke, or paravalvular leakage were found. In conclusion, ultrasonic aspirator allowed safe and secure annular debridement and could be a useful tool during minimally invasive aortic valve replacement.

Minimally invasive aortic valve replacement is commonly used to treat aortic valve disease through smaller incisions and upper hemisternotomy. No major differences in postoperative outcomes have been ...
Alkaptonuria, a rare disorder of homogentisic acid metabolism, can lead to aortic valvular calcification and stenosis. We present the case of a 71-year-old woman with alkaptonuria-associated aortic st...
Operations necessitating intervalvular fibrous body reconstruction in patients with extensive endocarditis are referred to as "Commando operations," an indicator of the procedure's difficulty. Aortic ...
What is the central question of this study? An increasing number of patients are in need of aortic valve replacement. It remains unresolved how surgical aortic valve replacement affects the cardiopulm...
Transcatheter aortic valve replacement becomes an equivalent alternative to surgical aortic valve replacement also in low-surgical-risk patients. Prosthetic valve endocarditis following transcatheter ...
The aim of the present study is to assess in a "real life" caselist the outcome of three different surgical approches for isolated aortic valve surgery in terms of surgery times, morbidity...
Aortic valve disease is a progressive illness that varies from minor valve thickening lacking obstruction of blood stream to severe calcification and alteration of the valve leading to wea...
This study evaluates the effectiveness and safety of surgical aortic valve replacement and transcatheter aortic valve replacement in aortic Stenosis.
This PAS is an observational, non-randomized, multi-center, single arm, clinical study to evaluate long term safety and effectiveness of the SJM™ Masters Series Hemodynamic Plus (HP) 15m...
The FinnValve investigators planned a nationwide registry to investigate the early and late outcome of transcatheter aortic valve implantation (TAVI) compared to surgical aortic valve repl...
Surgical treatment for severe AORTIC VALVE STENOSIS. Transcatheter aortic valve replacement (TAVR) is used as an alternative option in patients who are deemed at high risk or inoperable for traditional open-heart surgery.
The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.
Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).
Procedures that avoid use of open invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery.
A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and the MITRAL VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.
