An acute pulmonary embolism (PE) and the apical ballooning syndrome (ABS) are both critical and need proper management during the acute stage. We experienced a case of recurrent severe dyspnea because serious right ventricular dysfunction due to PE and left ventricular dysfunction due to ABS occurred consecutively in the short-term and bedside echocardiography has an important role in management in acute settings.

It has been well known that dilated cardiomyopathy (D-CMP) has characterized by systolic dysfunction of left ventricle (LV). But there are few studies about LV diastolic and right ventricular (RV) dysfunction in D-CMP. The purpose of this study is to assess the LV and RV systolic function as well as diastolic function in D-CMP. The purpose of this tudy is to assess the LV and RV systolic function as well as diastolic function in D-CMP. The gated blood pool scan (GBPS) was undertaken in 14 patients with D-CMP and 14 normal controls. The results are as follows : 1) Compared to normal controls, the global and regional ejection fraction of LV were significantly reduced (P<0.001) in D-CMP. But, there was no significant difference in LV ejection time between the two groups. 2) Peak filling rate and peak filling time were significantly reduced (P<0.001, P<0.05) in D-CMP 3) Global ejection fraction of RV was also significantly reduced in D-CMP compared to normal controls (P<0.001) But there was no significant difference in ejection rate of right ventricle between the two groups. 4) There was close correlation (R=0.802) between ejection fraction and filling rate of LV : filling rate was also reduced as ejection fraction decreased. And LV filling rate was also reduced with reduction of ejection rate. It is concluded that D-CMP shows diastolic impairment as well as systolic pumping failure and this systolic dysfunction is accounted for the diastolic impairment in D-CMP. And D-CMP shows also right ventricular dysfunction in almost all cases, as well as left ventricular dysfunction.

BACKGROUND AND OBJECTIVES: Heart failure rarely occurs in patients with thyrotoxicosis (6%), with half of the cases having left ventricular dysfunction (LVD). Although a few studies reported isolated right heart failure in thyrotoxicosis, there has been no evaluation of relationship between LVD and right ventricular dysfunction (RVD). SUBJECTS AND METHODS: We enrolled 12 patients (mean age: 51+/-11 years, 9 females) diagnosed as having thyrotoxicosis with heart failure and LVD {left ventricular ejection fraction (LVEF) <40%}, and divided them into two groups {Group I with RVD defined as tricuspid annular plane excursion (TAPSE) less than 15 mm and Group II without RVD}. Clinical features, laboratory variables, and echocardiographic parameters were compared between two groups. RESULTS: RVD was found in 6 (50%) patients. On admission, there were no significant differences between the two groups in clinical features, laboratory variables, or echocardiographic parameters including atrial fibrillation {6 vs. 5, not significant (NS)}, heart rate (149+/-38 vs. 148+/-32/min, NS), LVEF (36.7+/-9.5 vs. 35.1+/-6.3%, NS), or the tricuspid regurgitation peak pressure gradient (TRPPG, 30.9+/-2.0 vs. 36.3+/-9.3 mmHg, NS). After antithyroid treatment, all achieved an euthyroid state and both ventricular functions were recovered. All data, including the recovery time of LVEF and the change of heart rate between two groups, displayed no significant differences. CONCLUSION: In half of patients, RVD was combined with thyrotoxicosis-associated LVD. There were no differences in clinical factors or hemodynamic parameters between patients with and without RVD. This suggests that RVD is not secondary to thyrotoxicosis-associated LVD.

Pectus excavatum compresses the underlying right side of the heart, which might lead to right ventricular dysfunction as illustrated in this case report.

There are many differences between cardiac resynchronization therapy (CRT) and conventional pacing therapy in terms of indications and implant techniques. Generally speaking, CRT requires implanting 3 pacing leads in heart failure patients with ventricular dysynchrony. A left ventricular lead is implanted via intravenous coronary sinus. The pacing site of left ventricle has important influence on therapy response. Sometimes open chest implant or other pacing modes are adopted to compensate the anatomical limitation of coronary sinus and its branches. In addition, the pacing sites and modes of right atrium and right ventricle are also under research to further improve CRT response.

Back ground: The hypertension may lead the changes of the left ventricular geometry and the left ventricular diastolic dysfunction. There were many investigations about these abnormalities. Moreover, the treatment of the hypertensive patients with or without the left ventricular diastolic dysfunction is quite different. In Binh dinh general hospital, however, the left ventricular dysfuntion were neglected in practice. Thus, in this study, we evaluate the prevalence of these abnormalities in hypertensive patients. Subjects and method: We prospectively studied, from 6/2002 to 11/2003, 200 consecutive hypertensive patients admitted to the Internal Deparment at the Binh Dinh General Hospital. Echocardiography was performed on a Hewlett-Packard Image-Points with 2.5 and 3.5 MHz transducers. Measurements of the size of the ventricular walls are according to ASE. Doppler echocardiography is used to evaluate the characteristics of diastolic transmitral blood flow from the apical four-chaber view. The peak velocities of blood flow during early diastolic filling (E wave) and atrial contraction (A wave), the E-wave decelerating time and parameters of pulmonary venous flow revesal during atrial contraction are measured. The isovolumic relaxation time is measured from the apical-five chamber view. The diagnosis and classification of the left ventricular geometric changes and the abnormal diastolic filling patterns are based on the criteria of Devereux. Results: Prevalence of the left ventricular diastolic dysfunction was 61.5% of the hypertensive patients with the most frequent impaired relaxation pattern (48%). 72.5% of patients have the geometric changes in which the remodelling type consists of 47.5% concentric hypertrophy 25%.

External compression of the right ventricle (RV) due to a depressed sternum in patients with pectus excavatum is uncommon. Moreover, mid-RV obstruction-induced cachexia rarely occurs in patients with pectus excavatum. We report a case of cardiac cachexia caused by significant RV compression in a patient with pectus excavatum.
