Abstract

To evaluate the long-term survival of patients undergoing aortic root enlargement (ARE) compared with those with small aortic root (SAR), exploring risk factors for late mortality as well as the influence of patient-prosthesis mismatch (PPM). From January 1999 through December 2010, a total of 3724 patients underwent isolated or combined aortic valve replacement at our institution. From these, 239 (6.4%) had transannular ARE with a pericardial patch, to permit implantation of a larger prosthesis. This study population was compared with a control group of 767 patients (20.6%) who were considered to have SAR, as a prosthesis of size 21 or less was implanted. Mean age was comparable: 70.4 ± 12.5 vs 69.9 ± 9.6 years for ARE and SAR groups, respectively (P = 0.552). Female sex predominated in the control group (81.6 vs 88.0%; P = 0.011). Patients of the ARE group tended to have higher mean body surface area (1.59 ± 0.15 vs 1.57 ± 0.13 m(2); P = 0.061) and were less symptomatic (NYHA III-IV: 49.4 vs 57.9%; P = 0.021). Implantation of bioprostheses was more frequent in the ARE group (76.2 vs 52.3%; P < 0.001), while concomitant procedures were more frequent in the SAR group (25.5 vs 32.2%; P = 0.050). Patients in the SAR group had hig...Continue Reading

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Cardiomegaly

Cardiomegaly, known as an enlarged heart, is a multifactorial disease with different pathophysiological mechanisms. Hypertension, pregnancy, exercise-induced and idiopathic causes are some mechanisms of cardiomegaly. Discover the latest research of cardiomegaly here.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
