Postoperative mitral leaflet rupture in an infant with Loeys-Dietz syndrome

Successful replacement of the systemic tricuspid valve with a mechanical valve in a 3-month-old boy with congenitally corrected transposition of the great arteries having a dysplastic tricuspid valve

There are a few reports of successful replacement of the left-sided systemic tricuspid valve with a mechanical valve in small infants with congenitally corrected transposition of the great arteries having Ebstein's anomaly. Tricuspid valve replacement is the preferred option when pulmonary artery banding, performed as a prelude to performing the double-switch operation, is not feasible because of severe heart failure caused by tricuspid regurgitation.

CHD associated with syndromic diagnoses: peri-operative risk factors and early outcomes

CHD is frequently associated with a genetic syndrome. These syndromes often present specific cardiovascular and non-cardiovascular co-morbidities that confer significant peri-operative risks affecting multiple organ systems. Although surgical outcomes have improved over time, these co-morbidities continue to contribute substantially to poor peri-operative mortality and morbidity outcomes. Peri-operative morbidity may have long-standing ramifications on neurodevelopment and overall health. Recognising the cardiovascular and non-cardiovascular risks associated with specific syndromic diagnoses will facilitate expectant management, early detection of clinical problems, and improved outcomes--for example, the development of syndrome-based protocols for peri-operative evaluation and prophylactic actions may improve outcomes for the more frequently encountered syndromes such as 22q11 deletion syndrome.

Successful Single-Stage Operation for Loeys-Dietz Syndrome With Critical Coarctation of the Descending Aorta in a Young Adult

Patients with critical coarctation of the aorta complicated with Loeys-Dietz syndrome are extremely rare. We report a successful single-stage operation involving critical coarctation of the descending aorta with a bicuspid aortic valve, aneurysmal aortic root, and ascending aorta in a 19-year-old man. The patient was genetically evaluated and a novel heterozygous TGFBR2 mutation was detected.
