Tricuspid Stenosis

Tricuspid stenosis is characterized by reduced tricuspid orifice, thereby creating a barrier to the passage of blood from the right atrium to the right ventricle during diastole. The frequency of tricuspid stenosis is perceived differently by different authors. Congenital tricuspid stenosis is rare. Through hemodynamic investigation, the characteristic signs of tricuspid stenosis are found in […]


Tricuspid Valve Insufficiency

The most common cause of tricuspid insufficiency is the right ventricle and the valvular ring dilation causing secondary regurgitation (functional). It can occur as a complication of right ventricular decompensation from any cause.¬†Secondary pulmonary hypertension can accompany any form of heart disease or lung, but most commonly in lesions of the mitral valve. In general, […]


Mitral Valve Prolapse

Mitral valve prolapse is characterized by the prolapse of one or both sides of the valve into the atrium (over 2 mm) during the meso-systole. In primary forms, most commonly in young women, there is a Myxomatous degeneration of the valve, the ring and chordae, which allows penetration of mitral valve in the left atrium […]

Unstable Angina Pectoris

Myocardial infarction, together with the unstable angina pectoris are part of a group of diseases referred to as acute coronary syndromes (ACS). Depending on the changes that occur in the electrocardiogram (ECG) at rest, acute coronary syndromes may be with segment elevation or without ST segment elevation. ACS with the ST segment elevation is represented […]

Mitral insufficiency – Mitral regurgitation

Mitral insufficiency is a lack of hermetic closure of mitral valve during ventricular systole, allowing regurgitation of the blood from the left ventricle to the left atrium. This reflux of blood from the atrium to the left ventricle to the atrium during systole depends on the mitral orifice area that remains open because the gradient […]


Aortic Insufficiency

Aortic insufficiency is a valvulopathy characterized by sigmoid aortic valve injury from different causes, and the result is incomplete closure of these valves during ventricle diastole (relaxation). The direct consequence is the discharge into the left ventricle during diastole of a portion of the blood flow from the aorta. Among the most common causes of […]


Heart Anatomy

The heart is one of the most important organs of the human body. It is a hollow organ and is composed almost entirely of muscles. The weight of a normal heart is about 250-350 grams, yet has enough power to beat over 70 times per minute, thus pumping blood throughout the body. Presents:¬†From the outside: […]

Coronary Arteries – Anatomy

1. The left coronary artery – left coronary artery trunk (10-20 mm in length and a diameter of 3-6 mm) arises from the left coronary sinus above the aortic valve and is usually divided into: Anterior descending artery; Circumflex artery. Sometimes the trunk of the left coronary artery divides into three branches: the left anterior […]

Cardiac Pacemakers

Cardiac pacemaker implant or pacing is used to treat bradyarrhythmias and symptoms like syncope. A bradyarrhythmia represents any sort of rhythm or conduction disorder of the heart, which has the consequence of a low heart rate. In a clinical plan bradyarrhythmias may be manifested by symptoms such as dizziness, decreased exercise tolerance, tiredness, and syncope. […]

Heart Tumors – Myxoma

Primary tumors of the heart are rare and benign in three-quarters of the cases and a quarter are malignant, particularly sarcomas. It shows either chest pain, syncope, heart failure, blows, arrhythmias, conduction disturbances, pericarditis or tamponade, and whose signs and symptoms are related to the location of the disease. The most common primary cardiac tumor […]
