We specialize
Endoscopic Cardiac Surgery

Most of the heart surgeries we perform at our center are totally endoscopic, minimally invasive and endovascular

The aortic valve connects the left ventricle to the aorta. Narrowing of the valve leads to a reduced blood flow to the aorta

Tricuspid valve dysfunction may be due to insufficiency or stenosis or congenital diseases that prevent normal blood flow

Atrial septal defect is a common congenital heart disease, characterised by a deficit in the interatrial septum, which separates the left and right atria of the heart

Obstructive hypertrophic cardiomyopathy is succesfully treated surgically, with myectomy often accompanied by mitral valve repair

Surgical closure of the left atrial appendage and catalysis of atrial fibrillation is intended to convert
