This new method proposes a modification in the anastomosis of the superior vena cava aiming to pre-serve donor's right ventricular function by decompressing the pulmonary territory and reducing the pulmonary arterial pressure, as a biological ventricular assist device. Finally, a second intervention is proposed, where a "twist" is performed to place the donor's heart in an orthotopic position after re-moval of the native heart.

- Quadricuspid aortic valve (QAV) is a rare heart defect often found by chance during surgeries or autopsies.
- It is typically considered an isolated issue and can be categorized using a specific system by Hurwitz and Roberts, which classifies seven subtypes based on the size of the cusps.
- This report focuses on illustrating three distinct anatomical forms of the quadricuspid aortic valve anomaly.
Background: The study aim was to review the authors' experience with the surgical thrombectomy of mechanical valve thrombosis at the Heart Institute of the Medical School of São Paulo University, Brazil.
Methods: Between January 1993 and March 2014, a total of 21 patients (16 females, five males; mean age 48.2 years) with mechanical valve thrombosis was treated surgically.
We report a case of a 46 years-old woman, Caucasian, with hypertension and a primary diagnosis of infectious endocarditis. A transthoracic echocardiogram was performed suggesting right atrium myxoma. The patient was submitted to surgery, which found a tumor mass with a jelly-like exterior.
