RESUMEN

BACKGROUND: Ultrasound guided cardiac shock wave therapy (CSWT) is a noninvasive therapeutic option in the treatment of chronic-refractory angina. Clinical trials have shown that CSWT reduces angina symptoms, improves regional systolic function, LV ejection fraction, myocardial perfusion and quality of life parameters. Absolute measurements of myocardial perfusion before and after CSWT have not been performed so far. METHODS AND RESULTS: We studied a total of 21 CCS III patients with history of CAD and multiple interventions who suffered from disabling angina despite individually optimized medical therapy. An N-13 NH3 PET perfusion scan under adenosine was performed before and after CSWT treatment. CSWT was well tolerated in all patients. Absolute perfusion under adenosine of the global left-ventricular myocardium did not change under therapy or minimal coronary resistance. The treated segments, however, showed in terms of both perfusion and resistance a mild but significant improvement, by 11 and 15 %, respectively, whereas no change could be observed in the remote segments. Considering a threshold of increased perfusion of 5 %, 10 (77 %) out of 13 patients with a better target perfusion improved in their CCS class, whereas 3 (43 %) out of 7 patients without improved target perfusion improved in their CCS class too. CONCLUSION: Standard CSWT has the potential to improve myocardial perfusion of the therapy zone and clinical CAD symptomatology without affecting global myocardial perfusion. As a noninvasive and well tolerated therapeutic option, these data suggest the use of CSWT in patients with end-stage CAD.

RESUMEN

AIM OF THE STUDY: Regular physical activity has found to be a strategy to increase exercise capacity in patients with chronic heart failure (CHF). Next to endurance training also electromyostimulation (EMS) of thigh and gluteal muscles results in an increased capacity in CHF patients. EMS therapy was either done by stimulating 8 major muscle groups involving also trunk and arm muscles (extended electromyostimulation (exEMS)) in comparison to EMS therapy limited to gluteal and leg muscles (limEMS). METHODS: 31 individuals completed the EMS training program. Stable CHF patients (NYHA class II-III) received either exEMS (18 patients, 11 males, mean age 59.8±13.8 years) or limEMS (13 patients, 10 males, 63.6±9.4 years). Training was performed for 10 weeks twice weekly for 20 min, the level of daily activity remained unchanged. Effects on exercise capacity, left ventricular function (EF - ejection fraction) and QoL (quality of life) were evaluated. RESULTS: QoL was found to be improved in all domains of the SF-36 questionnaire. In the exEMS group there was a significant improvement in the domain physical functioning (54.09±29.9 to 75.45±15.6, p=0.48) and emotional role (63.63±45.8 to 93.93±20.1 p=0.048). LimEMS group showed significant improvement in the domain vitality (37.5±6.9 to 52.8±12.5, p=0.02).There was a significant increase of oxygen uptake at aerobic threshold in all groups (exEMS: +29.6%, p<0.001; limEMS +17.5%, p<0.001). EF -increased from 36.94±8.6 to 42.36±9.1% (+14.7%, p=0.003) in the exEMS group (limEMS 37.7±3.6 to 40.3±5.9% [+6.9%, p=0.18]). CONCLUSION: EMS contributes to an improved quality of life and can improve oxygen uptake and EF in CHF. It may be an alternative therapy in CHF patients who are otherwise unable to undertake conventional forms of exercise training.

RESUMEN

The key challenge in athlete's screening is the distinction between abnormal and normal which is hindered by the fact that the adaptation to sports activity in endurance athletes is different to that in power athletes. Especially cardiomyopathies provoke changes in ECG and echocardiography (echo) at an early stage when clinical symptoms are absent. ECG and echo data and their relationship to fitness peculiar to top handball players have never been described. We studied 291 male first league handball players (32 Olympians/47 national players) (25.3±4.4 years). Check up consisted of ECG, spiroergometry and echocardiography. None had T-wave inversions, 3.1% showed early repolarisation abnormalities in the precordial leads. Sokolow-Lyon voltage criterion for left ventricular hypertrophy was positive in 19.3%. Spiroergometry showed a maximum oxygen uptake (peakVO2) of 50.3±7.7 ml/min/kg body weight. LVmass was increased in comparison to normal values. There was a correlation between peakVO2 and LVindex (p<0.001, r=0.341), (LVmass/peak VO2 p=0.053, r=0.125). A relationship between cardiac dimensions and peakVO2 could not be confirmed. In professional handball players early repolarisation abnormalities were less frequent and LVmass was increased when compared with soccer players. The need for normal values for different types of sports is crucial to guarantee a proper evaluation of athletes.

RESUMEN

The purpose of this study is to assess the incremental value of tissue Doppler (TDI) derived displacement curves (TDint) compared to TDI velocity curves (TDvel) for the evaluation of left ventricular (LV) dyssynchrony (LVD). About 25 patients (pts.) with systolic heart failure were studied by TDvel and TDint. Four TDI sample volumes were placed at the basal and four at the mid ventricular myocardium, utilising two imaging planes. LV dyssynchrony (LVD) was defined as an interregional delay of >40 ms corrected for heart rate. 10 pts. had synchronous contraction, 15 pts. LVD as defined by two experts (EC). To determine diagnostic accuracy and intra-observer variability two identical sets of 100 documents (25 pts. x two imaging planes x two modalities) were produced and presented in random order to one trained (TR) and two untrained (UR) readers. The TR more frequently classified documents as unreadable (7.5 vs. 3.5%, P < 0.05) but more often as correct, i.e., consistent with EC (72.0 vs. 57.8%, P < 0.001). 8.7% of the documents were classified as unreadable using TDvel, 1.0% when applying TDint (P < 0.001). The mean value of correct classification of all 3 readers was 54.3% (TDvel only), 70.7% (TDint only), and 77.7% (combining both modalities), (P < 0.001). The kappa value for TR and TDint was 0.68, for TDvel 0.29. For UR, kappa did not differ (TDint: 0.58; TDvel 0.51). TDint is superior to TDvel in accuracy, reproducibility, and applicability for skilled and unskilled investigators when evaluating LVD by TDI. The combined application of TDint and TDvel is optimal.

RESUMEN

BACKGROUND AND OBJECTIVE: Percutaneous mitral valvotomy (MVT) with the Inoue balloon is the most frequently performed therapeutic alternative to surgical commissurotomy in patients with symptomatic mitral valve stenosis. Few data are available on the results of repeat MVT. PATIENTS AND METHODS: We compared the immediate and 3-month results of all patients who had a repeat MVT (n = 39) with those who had a primary intervention (n = 1,117) in our institution between February 1989 and January 2001. Mean age of the 31 women and 8 men with repeat MVT was 53 +/- 14 years at the first and 57 +/- 14 years at the second intervention performed 3 - 10 years later. RESULTS: Following primary intervention the invasively assessed mitral valve are (MVA) had increased from an average of 1.0 +/- 0.2 cm(2) to 1.7 +/- 0.4 cm(2). Echocardiography three months after the intervention revealed a MVA of 1.7 +/- 0.3 cm(2). Repeat MVT resulted in an immediate increase of MVA from 1.0 +/- 0.2 cm(2) to 1.6 +/- 0.4 cm(2), after 3 months the average MVA was 1.6 +/- 0.3 cm(2). According to the NYHA classification clinical symptoms had improved on average from 2.6 to 1.6 three months after primay intervention and from 2.8 to 2.1 three months following the repeat procedure. The incidence of significant procedure-related complications was less than 3 % for both primary and repeat MVT. CONCLUSION: The clinical and hemodynamic results demonstrated in our patients suggests repeat MVT as the treatment option of choice in mitral restenosis after previous balloon intervention, if mitral valve morphology is still suitable.

RESUMEN

BACKGROUND AND INTRODUCTION: Cardiac resynchronization therapy (CRT) is a promising non-pharmacological treatment option for patients (pts) with severe severe heart failure (CHF), systolic left ventricular (LV) dysfunction, and ventricular conduction abnormalities (VCA). Pt selection for CRT, however, is still controversial. Tissue Doppler echocardiography (TDE) can be used to analyze regional wall motion with high temporal resolution. PATIENTS AND METHODS: In 33 CHF pts with VCA (QRS width > or =140 ms) and 20 normal probands, left and right ventricular (RV) filling and emptying were analyzed by flow and tissue Doppler to assess regional (anterior, lateral, inferior, and septal) asynchrony within the LV as well as asynchrony between the RVand LV. All time measurements were corrected for a heart rate of 60 bpm. Results Maximum interventricular and segmental intraventricular delay was 30 ms in the normals. LV asynchrony, defined as a regional delay of > or =40 ms, was found in 29/33 (88%) of the CHF pts, in 4 cases there was synchronous LV contraction despite VCA. In the pts with LV asynchrony, 22 (67%) showed the maximum delay in the lateral wall, 7 (21%) in the septum. Inter- and intra-ventricular asynchrony correlated weakly. CONCLUSIONS: In many CHF pts with VCA, there is a delay both between the two ventricles, and among different LV regions. Predominantly but not exclusively, the LV lateral wall shows the maximum intra-LV delay. Some CHF pts, however, seem to have a synchronous LV contraction despite VCA. TDE thus adds important information for pt selection with respect to CRT.

RESUMEN

Clinical symptoms and diagnostic findings in patients with mitral stenosis are usually determined by the extent of the stenosis. Compared to a normal mitral valve area (MVA) of > 4 cm2, MVA in patients with severe mitral stenosis is usually reduced to < 1.5 cm2. In older patients symptoms are frequently influenced by concomitant diseases (e.g. atrial fibrillation, arterial hypertension or lung disease). An important diagnostic element besides anamnesis, auscultation, ECG and chest X-ray is echocardiography, which is required in order to measure non-invasively and reliably the mitral valve gradient (MVG), the MVA and morphologic changes to the valves, as well as concomitant valvular disease, ventricular functions and, where appropriate, left-atrial thrombi. In addition to the surgical treatment of patients with severe mitral stenosis, which has been an established procedure for 50 years, percutaneous balloon mitral valvuloplasty (MVP) has recently established itself as an alternative option. At the current time, the Inoue technique seems to display the most advantages. Following transseptal puncture, the Inoue balloon is guided transvenously into the left atrium and then into the left ventricle using a special support wire. The balloon is short and soft. Its special unfolding character enables it to be placed securely in the mitral valve without any risk of ventricular perforation (Figure 1). As with surgical commissurotomy, balloon valvuloplasty leads to a separation of fused commissures. This results in a significant reduction of MVG, accompanied by an increase in the MVA (Figure 2). The results and success of MVP are influenced by the morphology of the valves and the changes to the subvalvular apparatus. In randomized studies, the results of surgical commissurotomy were comparable with those of balloon mitral valvulotomy. In our hospital, an increase in MVA from 1.0 to 1.8 cm2 could be achieved in 899 patients (mean age 56 +/- 3 years). In younger patients with less significantly changed valves, the results were correspondingly more favorable than in older patients (Figure 3). Provided valve morphology is suitable, a relapse following previous surgical commissurotomy is not a contraindication for MVP. The MVP complication rate is very low in skilled hands: mortality is below 1%; mitral insufficiency occurs in 3 to 10% of interventions; we observed a severe mitral insufficiency in 5% of our patient group. Thromboembolic complications may be prevented after exclusion of atrial thrombi by transesophageal echocardiography. The occurrence of a hemodynamically significant atrial septum defect is a very rare event. The mid-term results (5 to 10 years) and the low restenosis rate following MVP in patients with suitable valves are comparable with those of surgical commissurotomy. In older patients with considerably changed, calcified and fibrotic valves, restenosis may be expected within 1 to 5 years. In these patients MVP represents no more than a palliative intervention in order to prolong the point of surgery, for example in patients where a concomitant aortic valve disease in itself is not yet an indication for surgery. Special indications are to be found in young patients with severe mitral stenosis yet few symptoms, in pregnant females and in emergency situations, as well as in patients with Grade II mitral stenosis with intermittent atrial fibrillation. Catheter therapy is much less invasive than surgery. In case of failure the patient still has the option of surgical therapy. Patients with morphologically significantly altered valves usually receive a valve replacement since an unsuccessful reconstruction would lead to a second operation within a very short time interval. Contraindications for MVP are thrombi in the left atrium, a previously existing > Grade II mitral regurgitation and marked, degenerative destruction of the subvalvular apparatus or extensive calcification of the valves. MVP thus represents a significant addi

RESUMEN

Primary tumors of the heart are very rare. We report a case of a 28-year old female patient in whom a tumor of the left ventricle was first diagnosed by transthoracic echocardiography. Angiography, nuclear magnetic resonance imaging and fasting positron emission tomography with 18-fluorodesoxyglucose suggested the diagnosis of a well vascularized tumor. The tumor was subtotally excised during heart surgery under total cardiopulmonary bypass and histological examination identified a predominantly vascular hamartoma.

RESUMEN

BACKGROUND: In hypertrophic obstructive cardiomyopathy (HOCM) therapy, surgical myectomy and DDD pacemaker implantation are considered to be established extensions to medical treatment. As an alternative procedure for reducing the left ventricular outflow tract gradient (LVOTG), percutaneous transluminal septal myocardial ablation (PTSMA) by alcohol-induced septal branch occlusion has been introduced. We report on the acute results and the short-term clinical course following 66 PTSMA interventions in symptomatic patients (pts.) with HOCM. METHODS: In pts. who were symptomatic despite adequate drug therapy (31 women, 35 men; mean age 52.9 +/- 15.0 years, range: 16-86) 66 PTSMA interventions were performed (4 pts. with a re-intervention). Septal branches were occluded by injection of 3.5 +/- 1.8 (1.5-11.0) ml ethanol (96%). In the first 30 pts. the target vessel was determined by probatory balloon occlusion (PBO) alone, in the following 36 by additional myocardial contrast echocardiography (MCE). In-hospital follow-up of LVOTG and clinical course were determined. RESULTS: The invasively determined LVOTG could be reduced by > 50% or eliminated in 54 interventions (82%) with a mean reduction from 71.2 +/- 34.4 (4-174) to 18.0 +/- 21.5 (0-105) mmHg at rest and from 145.7 < or = 42.3 (68-257) to 63.7 +/- 49.3 (0-185) mmHg post extrasystole (p < 0.0001). All pts. experienced angina pectoris within the first 24 hours. The creatine kinase peak was 690 +/- 364 (201-1810) U/l after 11.0 +/- 5.4 (4-24) hours. 45 pts. (68%) developed trifascicular block, requiring temporary, or in 9 cases (14%) permanent, (DDD) pacemaker implantation. Two pts. (3%) died 9 and 2 days after successful intervention, due to uncontrollable ventricular fibrillation associated with betasympathomimetic and theophylline treatment for chronic obstructive pulmonary disease in one case, and fulminant pulmonary embolism in the other. The remaining pts. were discharged after 11.1 +/- 4.6 (5-24) days following an uncomplicated hospital course. The introduction of MCE was associated with a higher percentage of short-term success (92% vs. 70%, p < 0.015). CONCLUSIONS: PTSMA in HOCM is a promising non-surgical technique for septal myocardial reduction with a consecutive reduction of the LVOTG. MCE has shown to be a useful addition to PBO for selection of the target vessel. Possible complications are trifascicular blocks requiring permanent pacemaker implantation and tachycardiac rhythm disturbances. Prospective, long-term observations of larger populations and a comparison with the established forms of therapy are necessary in order to determine the definitive significance of PTSMA.

RESUMEN

Percutaneous transluminal coronary angioplasty (PTCA) is an established therapy for coronary artery disease (CAD), whereas percutaneous transluminal septal myocardial ablation (PTSMA) is becoming increasingly significant in the therapy of symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM). We report the first ever simultaneous treatment, in a 62-yr-old patient, of significant HOCM and a 75% LAD stenosis from which the septal branch to be occluded stemmed. Using a double wire technique, first the septal branch was occluded through a fractional injection of 4 ml absolute alcohol, thus ablating the hypertrophied septal myocardium with reduction of the left ventricular outflow tract (LVOT) gradient at rest from 80 to 9 mmHg. Following this, the LAD stenosis was dilated and stented. Complications, in particular a trifascicular block or ventricular dysrhythmia, did not occur during the hospital stay. To conclude, combined PTSMA and PTCA may be considered as a therapeutic alternative to a combined surgical intervention in individual cases of symptomatic HOCM and CAD, provided that the potential complications are taken into account.

RESUMEN

OBJECTIVE: Percutaneous mitral valvuloplasty has been shown to be an acceptable alternative to surgery as treatment for selected patients with severe mitral stenosis. We examined hemodynamic, echocardiographic, and pathomorphologic findings in a series of 308 patients undergoing balloon valvuloplasty, 41 of whom underwent subsequent surgery, in search of possible predictors of an unsuccessful outcome. INTERVENTION AND RESULTS: Patients with severe mitral stenosis underwent Inoue single ballon valvuloplasty over a 48-month period and had follow-up for a mean of 14.5+/-16.8 months (range 1 to 64 months). Of the 308 patients, 267 (Group I) were clinically improved and stable throughout follow-up, while subsequent surgery was required in 41 (Group II) after 38.2+/-143.5 days (range 1 to 1212). Significant differences between the groups were observed for NYHA class (2.7+/-0.6 vs 2.9+/-0.6, p<0.05), mitral valve area (1.0+/-0.3 vs 0.9+/-0.2 cm2, p<0.01) and left atrial endsystolic dimension by echo (51.3+/-8.0 vs 55.4+/-10.2 mm, p<0.01). Two of the 41 Group II patients underwent surgery for left to right shunting, 1 for tamponade and 2 were lost to follow-up. The excised mitral valves of the remaining 36 patients all showed calcification and/or fibrosis: 9 homogenous, 5 non-homogenous; 19 were classified as having a funnel-shaped deformity, and 3 did not fit into a discrete category. Among the funnel-shaped valves, 13 had a tear versus 6 where dilation was primarily accomplished by stretching. Only one of 9 valves with homogenous calcification was torn, whereas a tear was noted in 3 of the 5 with non-homogenous calcification. CONCLUSION: Funnel-shaped valves and those with non-homogenous distribution of calcification and/or fibrosis appear to be least suitable for balloon valvuloplasty.

RESUMEN

To determine the feasibility of currently used, intravascular ultrasound catheters (12.5 and 20 MHz, 6F and 9F, Boston Scientific Corp., Watertown, MA) for mitral valve disease, ten excised mitral valves from patients with severe mitral stenosis were examined. The specimens were fixed in a glass cylinder perfused with water. The valves were planimetered with the intravascular ultrasound system and investigated regarding pathomorphological changes. The depth field of penetration was between 1.5 and 2 cm (3 to 4 cm diameter) in the 20 MHz catheter and between 2 and 2.5 cm (4 to 5 cm diameter) in the 12.5 MHz catheter. A good correlation of the experimentally recorded valve areas could be ascertained with the Gorlin formula (r = .71, P < .05), the Doppler echocardiography method (r = .69, time method (r = .75, p < .05), and with the two-dimensional echocardiography method (r = .69, P < .05). These results show a sufficient feasibility of the currently used, intravascular ultrasound catheters and enable further steps to be taken with regard to evaluating mitral valve morphology in vivo.

RESUMEN

BACKGROUND AND AIMS OF THE STUDY: Percutaneous mitral valvulotomy has been shown to be an accept able alternative to surgery as treatment for selected patients with severe mitral stenosis. Uncertainty still exists regarding predictors of unsuccessful outcome. MATERIALS AND METHODS: 308 patients with severe mitral stenosis underwent Inoue single balloon valvulotomy over a 48-month period and were followed up for a mean of 14.5 +/- 16.8 months (range one to 64 months). Two hundred and sixty-seven (Group I) improved clinically and remained stable throughout the follow up, while subsequent surgery was required in 41 (Group II) after 38.2 +/- 143.5 days (range one to 1,212). Clinical and echocardiographic parameters of the two groups were compared to find significant predictors of an unsuccessful outcome. RESULTS: Significant differences between the groups were observed for NYHA class (2.7 +/- 0.6 vs. 2.9 +/- 0.6, p < 0.05), mitral valve area (1.0 +/- 0.3 vs. 0.9 +/- 0.2 cm2, p < 0.01), left atrial end-systolic dimension by echo (51.3 +/- 8.0 vs. 55.4 +/- 10.2 mm, p < 0.01) and an echocardiographic scoring system including grading for eccentricity of the mitral orifice and distribution of commissural calcification (7.5 +/- 2.0 for Group I and 8.7 +/- 2.0 for Group II, p < 0.001). CONCLUSIONS: Mitral valves that are more likely to have an unsuccessful outcome can be identified by hemodynamic, clinical and echocardiographic criteria, including grading for eccentricity of the mitral orifice and distribution of commissural calcification.

RESUMEN

Percutaneous balloon mitral valvulotomy (PBMV) with the Inoue-balloon is a proven therapy in young patients with mitral stenosis. In this study, we investigated primary results in PBMV of elderly patients. In 383 patients with mitral stenosis PBMV was done with the Inoue-balloon. We compared primary success rates and short-term follow-up of 287 (74.9%) < 65-year-old patients and 96 (26.1%) > or = 65-year-old patients. Elderly patients were more likely to have atrial fibrillation (58% vs. 45%; p < 0.05), tricuspid regurgitation < or = II degrees (58% vs. 45%; p < 0.05), coronary artery disease (16% vs. 6%; p < 0.01), and previous pulmonary edema (42% vs. 30%; p < 0.05). PBMV was successful in 73.9% of the elderly and 84.7% of the younger patients (p < 0.05). Mitral valve gradients could be reduced from 12.5 +/- 11.6 mm Hg to 6.2 +/- 6.8 mmHg (p < 0.001) in elderly patients and from 15.5 +/- 6.9 mm Hg to 7.0 +/- 3.2 mm Hg (p < 0.001) in younger patients. Mitral valve areas increased from 1.0 +/- 0.3 cm2 to 1.6 +/- 0.5 cm2 (p < 0.001) in elderly patients and from 1.0 +/- 0.3 cm2 to 1.7 +/- 0.4 cm2 (p < 0.001) in younger patients. No patient died during the procedure. Two younger patients had emergency surgery because of pericardial tamponade following transseptal puncture. After PBMV elderly patients had more often an increase of mitral regurgitation (47% vs. 35%; p < 0.05) without need of an emergency mitral valve replacement.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

A 27-year-old man known to have corrected transposition of the great arteries (CTGA) associated with a ventricular septal defect (VSD) was admitted to our hospital with a suspected increase of the shunt volume. The patient is a first class bodybuilder. Heart catheterization confirmed the diagnosis of a "right-ventricular" mass obstructing the "right-ventricular" outflow tract, which had already been seen at echocardiography. The intraoperative finding showed the tumor to be accessory tissue of the anterior tricuspid leaflet prolapsing through the VSD into the subvalvular outflow tract of the right ventricle. The accessory tricuspid valve tissue was removed by transatrial access. The VSD was closed by a dacron patch using the same route. The postoperative course was uneventful.

RESUMEN

In eleven patients with aortic dissection or perforated endocarditic aortic wall abscess cavity, the diagnostic usefulness of Color Doppler Echocardiography (CDE) for the identification of true and false lumen as well as the perforation jet was assessed by comparison with the findings of angiography, digital subtraction angiography, computed tomography and surgery. The information gained in addition to that of these procedures, as well as to that of the four conventional echocardiographic techniques was evaluated. Six patients had aortic dissections of DeBakey type I or III; in all of them the diagnosis had been established with conventional ultrasonic techniques. Similarly, in all patients with aortic dissection of DeBakey type I, a clear differentiation between true and false lumen in the aortic root and ascending aorta could already be made by grey-scaled echocardiography. In these patients, however, CDE made the additional demonstration of the perforation jet into the false lumen possible. In those three patients with aortic dissection of DeBakey type III as well as in the abdominal aortic region of DeBakey type I, color Doppler echocardiography was the only method to define true and false lumen and to clearly localize the perforation sites. Two further patients were found to have a small, local dissection, which could only be assumed by conventional echocardiography; the color Doppler M-mode image led to a clear diagnosis. In three patients an endocarditic abscess cavity of the aortic wall could be detected by conventional echocardiography. Two-dimensional color Doppler echocardiography additionally enabled us to visualize the presence and the course of perforation flows. In two patients color-coded Doppler echocardiography made it possible to detect perforations in regions which could not be localized either with conventional echocardiographic techniques or the above-mentioned control procedures.
