Transcatheter aortic valve replacement (TAVR) is an alternative treatment for selected patients with severe aortic valve stenosis who are at high risk for conventional surgery. Critical stenosis of left main coronary artery as a late complication after TAVR is quite rare.

Percutaneous valve implantation or surgical replacement with mechanical or biological valves are standard therapies for severe valvular heart diseases. Prosthetic valve thrombosis, though rare, is a serious complication, particularly with mechanical prostheses. This study aimed to investigate the predictive value of platelet volume parameters, including mean platelet volume (MPV), platelet distribution width (PDW), and platelet-large cell ratio (P-LCR), for valvular thrombosis risk in patients undergoing valve replacement therapy.

Subvalvular aortic stenosis typically manifests at a young age and rarely presents in adulthood. It may cause left ventricular outflow tract stenosis, which requires surgical treatment in severe cases. The coexistence of discrete subvalvular aortic stenosis and quadricuspid aortic valve is a highly unusual finding.

The VACTERL (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities) association represents an enigmatic syndrome requiring further study. This report describes a full-term neonate born to a multiparous woman who was found, upon further examination, to have multiple congenital abnormalities, including a bicuspid aortic valve, patent foramen ovale, tracheoesophageal fistula (TEF), asymmetric crying facies, microphallus, and a single inguinal testis. The discussion explores environmental and genetic factors that may contribute to this association, as well as similar conditions, such as CHARGE (coloboma, heart defects, choanal atresia, growth retardation, genital abnormalities, and ear abnormalities) syndrome.

The Y incision and roof technique for aortic valve replacement enable implantation of a large prosthetic valve and extensive enlargement of the sinotubular junction. Surgeons have been reluctant to adopt a minimally invasive approach for this procedure because of its complexity and risk. The Stonehenge technique was designed to achieve an ideal surgical view of the aortic root through a small right thoracotomy.

Valve-sparing aortic root replacements have acceptable reintervention rates in patients with failed pulmonary autografts after a Ross procedure. In our 50-year-old patient with post-Ross valve-sparing aortic root replacement, we report preoperative and postoperative 4-dimensional flow magnetic resonance imaging capturing changes in peak systolic velocity, 3-dimensional systolic flow profiles, and aortic wall shear stress that may predict a decreased risk of aortic dilation, a common complication in repeated Ross procedures.
