Clinical Study on Congenital Heart Diseases in Adulthood.

Korean Circulation Journal.1987;17(3):443-450. doi:10.4070/kcj.1987.17.3.443

A clinical study is done on 234 adult patients with congenital heart disease who visited Dong San Hospital, Keimyung University during the period of January 1982 to May 1987. Among those the number of men is 109 and the female is 125. There are female preponderance in atrial septal defect and patent ductus arteriosus while male in tetralogy of Fallot and pulmonary stenosis. Most of patients are found below 30 years of age and the incidence decrease with age; below 30 years of age, ninty percent of ventricular septal defect, eight-eight percent of tetralogy of Fallot, eighty-four percent of patent ductus arteriosus and seventy-seven percent of atrial septal defect are found. The incidence of congenital heart diseases in adult are as follow; ventricular septal defect 30.8%, atrial septal defect 30.3%, tetralogy of Fallot 17.1%, patent ductus arteriosus 12.8%, pulmonary stenosis 3.4% and miscellaneous congenital diseases 4%. Associated anomalies of major congenital heart diseases are as follows; the most commonly associated anomaly in ventricular septal defect is pulmonary stenosis, and Sinus Valsalva aneurysm with/without rupture or aortic regrugitation is frequently associated in ventricular septal defect. Mitral regurgitation or pulmonary stenosis are frequently as sociated with atrial septal defect. Patent foramen ovale or atrial septal defect and persistent left superior vena cave are associated with tetralogy of Fallot. The lesion of aortic valve is frequent in patient ductus arteriosus.

Korean Circulation Journal.1987;17(3):435-442. doi:10.4070/kcj.1987.17.3.435

Abnormal left ventricular diastolic properties have been reported in dilated cardiomyopathy (DC). Characteristics of transmitral flow were analysed in 37 patients with DC and 29 age matched normal subjects by pulsed Doppler echocardiography. Peak flow velocity of early diastole(PFVE, E), atrial systole (PFVA, A), E/A and deceleration rate of early diastolic flow (DEF) were measured from mitral Doppler spectrum. The extent of mitral regurgitation (MR) was determined by mapping method in the left atrium. Significant mitral regurgitation was founded in 27 out of 37 patients. Three distinct transmitral flow velocity patterns were demonstrated. Ten Patients without significant MR(27%, group 1), PFVE(58+/-17 cm/s), PFVA(73+/-17 cm/s) and E/A (0.94+/-0.4) were significant different from normal subjects (73+/-11 cm/s, 61+/-11 cm/s, 1.22+/-0.26, P<0.025, P<0.005, P<0.05, respectively). In contrast 17 patients with significant MR(46%, group 2) showed higher E (89+/-24 cm/s), lower A(52+/-19 cm/s), higher E/A (1.83+/-0.6) and DEF (596+/-149 cm/s2) than group 1 patients. Remained 10 cases (27%, group 3) had higher single peak flow (104+/-25 cm/s) with higher DEF and significant MR. In conclusion, abnormalities of left ventricular filling are detected in dilated cardiomyopathy without MR but not in DC with MR by Doppler echocardiography. The presence of MR, which augments early diastolic filling, may mask abnormal diastolic filling properties of DC.

Korean Circulation Journal.1987;17(3):427-433. doi:10.4070/kcj.1987.17.3.427

In 25 aortic regurgitation patients relationship between degree of aortic regurgitation graded by 2-D color Doppler echocardiography and diastolic fluttering of anterior mitral leaflet on M-mode echocardiography was evaluated. The results were that all 13 aortic regurgitation patients, not associated with mitral stenosis, showed diastolic fluttering of anterior mitral leaflet; but only 3 patients among 12 patients (25%), associated with mitral stenosis, had characteristic mitral fluttering. On the whole, regardless of associated mitral stenosis, the sensitivity was 64%. In severe aortic regurgitation (Grade 3, 4 group) 12/13 patients revealed diastolic fluttering of anterior mitral leaflet (sensitivity of 92%); in mild to moderate aortic regurgitation (Grade 1, 2 group), only 4/12 patients (sensitivity of 33%). In conclusion, 2-D color Doppler echocardiography is a very useful method for detection of aortic regurgitation without difficulty. And in aortic regurgitation, not associated with mitral stenosis, fine fluttering of anterior mitral leaflet is a very sensitive sign of existence of aortic regurgitation, though there may be some false positive findings in normal individuals.

Usefulness of Pressure Half Time by Pulse Doppler Ultrasound in Evaluation of the Severity of Mitral Stenosis.

Yung Woo SHIN

Korean Circulation Journal.1987;17(3):419-425. doi:10.4070/kcj.1987.17.3.419

Twenty-seven patients with moderate or severe mitral stenosis (MS) were studied by cardiac catheterization and angiography, 2-dimensional (2-D) echocardiography and Doppler echocardiography to assess the ability of Doppler ultrasound to accurately measure mitral valve orifice area and to assess whether mitral regurgitation (MR) affected the calculation. Mitral valve area by Doppler was determined by the pressure half time method. There were good correlation between 2-D & Doppler echocardiography (r=0.84) and between cardiac catheterization & Doppler echocardiography (r=0.83) regardless of the presence of MR. It is concluded that the Doppler echocardiography provides a simple, accurate, useful noninvasive method for the estimation of mitral valve area in patients with MS even in the presence of complicating MR.

Aortic root diameter by two dimensional and M-mode echocardiography in predicting prosthetic aortic valve size preoperatively was measured in 10 adult patients undergoing aortic valve replacement. Correlation of aortic root diameter measured by two dimensional echocardiography and actual prosthetic valve size implanted by aortic valve replacement was excellent. Correlation coefficient was statistically significant (r=0.91, P<0.001). Correlation of aortic root diameter measured by M-mode echocardiography and actual prosthetic valve size was also excellent. Correlation coefficient was statistically significant (r=0.86, P<0.001). This study demonstrates that aortic root diameter by two dimensional and M-mode echocardiography can accurately predict prosthetic aortic valve size in patient undergoing aortic valve replacement.

To determine whether are significant diastolic left ventricular dysfunctions in mild to moderate hypertensive patients with normal systolic function, radionuclide ventriculography by in vivo red cell labelling technique using 20 mCi of (99m)Tc pertechnetate was performed in 24 hypertensive patients(mean age: 50.6+/-12.4, mean blood pressure: 156.9+/-11.8/100.6+/-7.1 mmHg) and in 11 normal subjects (mean age: 42.7+/-13.5, mean blood pressure: 123.2+/-6.8/82.3+/-3.9 mmHg). The results were as follows: 1) Ejection fraction was similar in both hypertensive and control groups (0.70+/-0.06 versus 0.70+/-0.08). 2) Mean of the peak filling rate (PFR) was significantly lower in hypertensive group (2.07+/-0.45 EDV/sec) than in control group (2.42+/-0.30 EDV/sec) (p<0.05). 3) Mean of the time to peak diastolic filling (TPDF) in hypertensive patients was 189.0+/-30.4 msec and which was significantly longer than that of control subjects (164.5+/-22.4 msec)(p<0.02). 4) Mean of the first third filling fraction (1/3 FF) in hypertensive patients was 0.22+/-0.07 and which was significantly lower than that of control subjects (0.32+/-0.09)(p<0.01). 5) Decreased PFR and delayed TPDF were also demonstrated with advances in age in both groups. Above results suggest that the diastolic evaluation of left ventricle might be necessary in the hypertensive patients with normal systolic function, and that diastolic dysfunction may precede the systolic dysfunction and clinical deterioration.

In surgeries that require the implantation of a pacemaker, the endocardial pacemaker leads are introduced into the cardiac chambers through subclavian or axillary venous catheterization or cephalic vein cutdown. The drawback of this type of surgery is scarring of the pectoral area, which can be a serious cosmetic problem especially for young women. In this study, we report on 2 cases where a permanent pacemaker in two young women with symptomatic bradycardia was implanted using a transaxillary incision. Both patients successfully recovered with no complications and were asymptomatic for more than 17 months after the procedure. Therefore, we found that implantation of a pacemaker via transaxillary incision provided excellent cosmetic results and should be considered in young women that require this type of surgery.

Korean Circulation Journal.2008;38(9):495-499. doi:10.4070/kcj.2008.38.9.495

It is rare to observe ST-segment elevations in the precordial leads that are caused by an occlusion of the right coronary artery and/or its branches. We report here on two cases of acute occlusion of the right coronary artery or its branches that caused acute right ventricular myocardial infarction with ST-segment elevations in the anterior precordial leads. These cases should remind us that the presence of diffuse ST-segment elevations in the precordial leads could be due to acute occlusion of the right coronary artery.
