BACKGROUND Less invasive cardiac surgery is widely adopted nowadays. Upper or lower partial sternotomy is an approach for less invasive cardiac surgery. We report results of less invasive cardiac surgery via partial sternotomy. METHODS From August 1, 2009 to September 30, 2010, 35 patients underwent cardiac surgery via upper or lower partial sternotomy. The preoperative characteristics, opera...

Cardiac tamponade is a rare and potentially fatal outcome in patients who undergo atrial fibrillation (AF) ablation1. In the US about 2.7 million are known to have AF, of those approximately 0.8% catheter ablation. perforation with radiofrequency ablation (RFA) likely occurs through two mechanisms: mechanical complications sheath or steam pops RFA. Surgery repair cardiac more common after pop2....

Background-—Mammalian heart regenerative activity is lost before adulthood but increases after cardiac injury. Cardiac repair mechanisms, which involve both endogenous cardiac stem cells (CSCs) and cardiomyocyte cell-cycle reentry, are inadequate to achieve full recovery after myocardial infarction (MI). Mice deficient in S-nitrosoglutathione reductase (GSNOR ⁄ ), an enzyme regulating S-nitroso...

Exercise can induce physiological cardiac growth, which is featured by enlarged cardiomyocyte cell size and formation of new cardiomyocytes. Telocytes (TCs) are a recently identified distinct interstitial cell type, existing in many tissues and organs including heart. TCs have been shown to form a tandem with cardiac stem/progenitor cells in cardiac stem cell niches, participating in cardiac re...

The urodele amphibians, salamanders and newts, represent the phylogenetic group closest to mammals capable of performing complete myocardial regeneration following ventricular resection. resection model has generated a basic knowledge processes involved in cardiac repair. However, does not relate well clinical situations which tissue damage, apoptosis, necrosis, fibrosis, hypertrophy are all ke...

Introduction:  In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...
