Abstract PDF: Postinfarction ventricular septal rupture (VSR) is a rare but fatal complication of acute myocardial infarction. In many cases, postinfarction VSR leads to hemodynamic instability and urgent surgical treatment is necessary. Here we describe a case of a patient with right ventricular (RV) dysfunction caused by acute RV infarction and with cardiogenic shock, whose condition improved after development of postinfarction VSR, but the patient died after corrective surgery.

P wave dispersion as a predictor of idiopathic paroxysmal atrial fibrillation.: Gue Ru Hong, Woong Kim, Jong Seon Park, Dong Gu Shin, Young Jo Kim, Bong Sup Shim; Yeungnam Univ J Med. 2001;18(2):267-276. Published online December 31, 2001; DOI: https://doi.org/10.12701/yujm.2001.18.2.267

Abstract PDF: BACKGROUND
P wave dispersion(PWD) is defined as the difference between the maximum and minimal P wave duration in any of the 12 leads of the surface ECG. The prolongation of atrial conduction time and the inhomogeneous propagation of sinus impulse are known electrophysiologic features in patients with paroxysmal atrial fibrillation(PAF). The purpose of this study was to determine the role of P wave dispersion for the prediction of PAF and to evaluate the effectiveness of prophylactic antiarrhythmic therapy. MATERIALS AND METHODS: The study population included 20 patients with a history of idiopathic PAF and 20 age and sex matched healthy control subjects. We measured the maximum P wave duration(P maximum) and P wave dispersion from 12 lead ECG. RESULTS: P maximum and P dispersion in idiopathic PAF were significantly higher than normal control group(97.2+/-12, 48.5+/-9msec vs, 76.5+/-11, 21+/-8msec, respectively p<0.001, <0.001). After 12-month follow up period P maximum and P dispersion were significantly reduced than those of initial state(77.2+/-13, 26.4+/-9msec vs. 97.2+/-12, 48.5+/-9msec, respectively p<0.001,<0.001). CONCLUSION: P dispersion and P maximum were significantly different between patients with idiopathic PAF and healthy control group. Those are easily accessible, non-invasive simple electrocadiographic markers that could be used for the prediction and prognostic factors of idiopathic PAF.

Abstract PDF: Primary cardiac lymphoma defined as involving only the heart and pericardium, is very rare and is diagnosed predominantly late in the course of illness or autopsy. This tumor is commonly fatal and until recently were rarely diagnosed antemortem. Recently, it was reported in patients with acquired immunodeficiency syndrome. We report a case of primary cardiac lymphoma in a 56 year old female who showed progressive exertional dyspnea. On echocardiogram and CT scan, large ill defined mass was demonstrated in right atrial and ventricular wall. It was diagnosed as B-cell type lymphoma on open cardiac biopsy.

Abstract PDF: BACKGROUND
Systemic embolism especially, cerebral infarction is one of the most important complications in patients with mitral stenosis. The authors analyse the some that could predict the development of cerebral infarction in cases of mitral stenosis and propose preventive therapeutic measures. METHODS: Retrospective study of 127 patients with rheumatic mitral stenosis was performed by analysis their medical records for transthoracic(TTE) or transesophageal echocardiography(TEE) over a 12months period. The patients were divided into two groups according to the presence (Group I: n=26, age: 55+/-13 years) or absence (Group II: n=101, age: 48.5+/-13 years) of cerebral infarction. No significant difference was observed between the two groups with respect to sex and functional class. RESULTS: Patients of group I were older (55.0+/-13 vs 48.5+/-13;p<0.05), had more dilated left atrial size(5.10+/-0.48 vs 4.81+/-0.70;p<0.05) and smaller mitral surface area(1.01+/-0.39 vs 1.21+/-0.45;p<0.05). In Group I, the incidence of atrial fibrillation(22 out of 26 vs 57 out of 101;p<0.05) and spontaneous left intra-atrial contrast phenomenon(22 out of 26 vs 44 out of 101;p<0.05) was more frequently observed. On multivariate analysis, atrial fibrillation and anticoagulant therapy were the independent predictive factors. CONCLUSION: Age, left atrial dilatation, the severity of mitral stenosis, the presence of spontaneous contrast and especially the presence of atrial fibrillation are the main predictive factors of the development of cerebral infarction in mitral stenosis. Patients presenting one or several of these factors may benefit from prophylactic anticoagulant treatment.

Antihypertensive effect and safety of imidapril on the patient with essential hypertension.: Gue Ru Hong, Jun Ho Bae, Dae Jin Jun, Jong Seon Park, Dong Gu Shin, Young Jo Kim, Bong Sup Sim; Yeungnam Univ J Med. 1999;16(1):69-75.

Abstract PDF: Imidapril(Tanatril(R)), a newly developed ACE inhibitor, has been used to treat hypertension and congestive heart failure. This study was designed to assess the antihypertensive effect and safety of Imidapril(Tanatril(R)) in patient with essential hypertension. 5-10mg of imidapril(Tanatril(R)) was administered once day in 30 patients with essential hypertension and followed up to 8 weeks. We tested the drug's effectiveness, safety, and the incidence of imidapril induced dry coughs. After 8 weeks of treatment with Imidapril, 76.2%(16/21) of patient showed lowered blood pressure and 47.6% showed normal blood pressure. The overall incidence of adverse effects was 33.3%(7/21). and among these adverse effects. dry cough was shown in only 9.5%. Thus, concluded that imidapril(Tanatril(R)) is as safe and effective as other ACE inhibitors. especially with imidapril showing very little incidence of dry cough compared to other ACE inhibitors.
