[Coronary radiography in patients with valvular cardiopathies and stenocardia]
Insights
Selective coronarography is not routinely necessary for patients undergoing valvular prosthetization. While coronary artery disease occurs in some patients with valvular cardiopathies, it doesn't warrant universal screening.
Area of Science:
- Cardiology
- Cardiovascular Surgery
Background:
- Valvular cardiopathies are common heart conditions affecting valve function.
- Coronary artery disease can coexist with valvular heart disease.
Purpose of the Study:
- To evaluate the necessity of routine coronary angiography in patients with valvular cardiopathies.
- To determine the prevalence of significant coronary artery stenosis in this patient group.
Main Methods:
- Seventy patients with valvular cardiopathies underwent selective coronarography and hemodynamic examination between 1973-1983.
- Patients were categorized by valvular lesion type (aortic, mitral-aortic, mitral).
Main Results:
- Significant coronary artery stenosis (over 50%) was found in 9 patients (12.85%), with an average age of 47.44 years.
- Angina pectoris was present in 81.42% of patients.
- Patients with coronary alterations had higher mean left ventricular telediastolic pressure compared to those with intact coronary arteries.
Conclusions:
- Systematic coronary angiography is not deemed necessary for all patients scheduled for valvular prosthetization.
- The prevalence of coronary artery disease in this cohort suggests a need for selective, rather than routine, investigation.
Abstract:
Seventy patients with valvular cardiopathies were performed selective coronarography besides the routine hemodynamic examination during the period 1973-1983. Those 70 patients could be subdivided in the following way: 46 with aortic, 17 - with mitral-aortic and 7 with mitral valvular lesion. Their average age is 46,15 +/- 1,42. Considerable changes (stenosis over 50% of at least one artery of the three main ones) were established in 9 patients (12,85%). The average age of the patients with the changes is 47,44 +/- 1,64. Angina pectoris had 57 out of 70 patients (81,42%). The mean telediastolic pressure of left ventricle of the patients with coronary alterations was 3,94 +/- 0,63 kPa (29,6 +/- 4,71 mm Hg) whereas the others, with intact coronary arteries had a mean telediastolic pressure of 2,6 +/- 0,43 kPa (19,43 +/- 3,26 mm Hg). Out of the nine patients with coronary changes--6 were males and 3--females. All had aortic valvular lesions--four with high degree stenosis, there--with high degree insufficiency and two--with mixed defect. The authors think that the systematic coronarographic investigations of the patients that are to have valvular prosthetization, is not necessary.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
