[Diagnosis and therapy of cardiovascular diseases in elderly patients. Do different criteria apply?].
The risks associated with cardiac catheterization and coronary angiography increase with advancing age while at the same time, cardiovascular morbidity and mortality also rise. This means that the risks attendant on the two invasive diagnostic procedures can be accepted if they can be expected to identify the prognostically best form of treatment for the individual patient. Even in old age, CAD patients undergoing PTCA or coronary surgery are at an advantage in terms of long-term results and quality of life over patients receiving medical treatment only. From this it follows that the geriatric patient must not be excluded from such diagnostic and therapeutic procedures. Similarly, in the case of coronary thrombolysis following myocardial infarction, age per se must not be considered a contraindication. Finally, hypertension needs to be treated rigorously in the elderly too, albeit with consideration being given to certain differential therapeutic aspects.

Frequency of primary tumors of the heart.
Primary tumors of the heart are rare. Based upon the data of 22 large autopsy series, the frequency of primary cardiac tumors is approximately 0.02%--corresponding to 200 tumors in 1 million autopsies (Table I).

[Coronary angiography in patients over 80 years of age. Therapeutic consequences and long-term follow-up].
Today, an increasing number of old and very old patients is referred for invasive cardiovascular procedures. At our institution, cardiac catheterization has been performed in 82 patients 80 years of age or older (50 m, 32 f; mean age 82 +/- 2 years) during the last 11 years; in 70 patients, because of clinically proven or suspected coronary heart disease, and in 12 patients, because of heart valve disease. In comparison with younger patients, elderly patients with coronary heart disease more often presented with unstable angina, or had multivessel disease and reduced ejection fractions. PTCA (n = 25) and bypass grafting (n = 7) aimed at revascularization in 32 patients; in 38 patients, medical treatment was continued. Furthermore, valve replacement (n = 7) or valvuloplasty (n = 1) were judged to be indicated in 8 of the 12 patients with heart valve disease. Diagnostic procedure was more frequently burdened with serious complications in elderly than in younger patients (5/82 versus 3/300, p < 0.01). During follow-up of 25 +/- 23, median 21 months, cardiovascular events were significantly less frequent in patients with coronary heart disease who had undergone revascularization procedures than in those with medical therapy (2/29 versus 9/36; p = 0.05); more revascularized patients were free of angina at the time of reevaluation. Thus, risks of invasive diagnostic procedures are increased in very old patients. Diagnostics, however, result in therapeutical consequences, revascularization obviously improves symptomatology and prognosis in patients at extremely advanced age suffering from coronary heart disease.

Cardiac myxomas.
Although cardiac myxomas are histologically benign, they may be lethal because of their strategic position. They can mimic not only every cardiac disease but also infective, immunologic, and malignant processes. Myxomas must therefore be included in the differential diagnosis of valvular heart disease, cardiac insufficiency, cardiomegaly, bacterial endocarditis, disturbances of ventricular and supraventricular rhythm, syncope, and systemic or pulmonary embolism. The symptoms depend on the size, mobility, and location of the tumor. Echocardiography, including the transesophageal approach, is the most important means of diagnosis; CT and MRI may also be helpful. Coronary arteriography in patients over 40 years of age is generally required to rule out concomitant coronary artery disease. Surgical removal of the tumor should be performed as soon as possible; the long-term prognosis is excellent, and recurrences are rare. In follow-up examinations as well, echocardiography is essential.

[Right ventricular metastasis of renal cell carcinoma 10 years after kidney transplantation].
In a 61-year-old man, renal cell carcinoma of the right kidney was diagnosed 10 years after renal transplantation. Echocardiography revealed a right ventricular mass 5.5 x 3.5 m in size. The patient died suddenly 10 weeks later, post-mortem examination confirmed diagnosis of right ventricular metastasis of renal cell carcinoma. This case underlines the importance of echocardiographic examination in tumor patients if signs of heart failure, angina pectoris, embolism, or rhythm disturbances arise; or if cardiac murmur becomes audible, or heart size increases.

[Percutaneous transluminal coronary angioplasty in patients with clearly restricted left ventricular pump function].
Among nearly 2000 consecutive PTCA-patients 42 (36 male, six female; mean age 60 +/- 11 years) had ejection fractions < or = 35% (mean 30 +/- 5%). 34 patients suffered from unstable and eight from stable angina. All had previous myocardial infarction and of these 23 had recent myocardial infarction. Four patients had prior coronary bypass surgery and one had undergone aneurysmectomy. 31 of 42 (= 74%) patients had multiple vessel disease (stenoses > 50%). Successful procedure was achieved in 35 of 42 patients (= 83%). The lesion-related success rate of PTCA was 89%, of recanalization 60%. Six procedures were multiple vessel PT-CA. Major complications occurred in two of 42 patients (one myocardial infarction, one emergency bypass operation). The in-hospital mortality was 2.4%. Follow-up angiography was performed in 22 patients and showed restenoses in nine cases. All patients underwent repeat coronary angioplasty, of these one patient had postprocedural myocardial infarction. The ejection fraction had meanwhile significantly improved from 29 +/- 5% to 36 +/- 7%. Clinical follow-up after 18 +/- 14 months (two to 53 months) was available in 39 of 40 patients, who were discharged from hospital without major complications. 29 patients were free of angina or anginal class II, one had a late cardiac transplant. Five patients had died of cardiac and one of noncardiac causes. Thus, PTCA in patients with severely depressed ventricular function shows acceptable acute results, which are comparable to those of routine angioplasty, continued symptomatic improvement can be achieved. However, the late outcome is significantly worse than in patients with normal left ventricular function.

Surgical removal of a lipoma of the heart.
In a 29-year-old woman echocardiography revealed a tumour originating from the anterior wall of the right ventricle. Noninvasive findings aroused suspicion of a lipoma. The tumour was removed under cardiopulmonary bypass, the resulting defect in the right ventricular wall being covered with a Goretex patch. Histological examination classified the tumour as a rhabdomyolipoma.

Evaluation of left ventricular inflow and volume by MR.
Considerable progress has been achieved during the past few years in the evaluation of intracardial blood flow by MR. Similar to ultrasound Doppler, it is possible now to registrate parameters of left ventricular diastolic filling as E/A ratio, velocity time integral of A- to E-wave (A(area)/E(area)), or isovolumetric relaxation time index. A total of 24 patients (7 women, 17 men, aged 24-69 yr) were examined, 5 of whom suffered from a hypertensive heart disease, 5 from a coronary heart disease, and 7 from mitral valve stenosis of various degree; 7 showed normal findings. E/A-ratio, A(area)/E(area), as well as isovolumetric relaxation time (IVRT) were evaluated by two different examiners on the same day by MR and ultrasound-Doppler, showing correlation factors of .89 for E/A ratio, .67 for A(area)/E(area), and .76 for IVRT in comparing both techniques. Additionally, to test the potential for making left ventricular function diagnoses from MR, time-volume curves for normal cases and patients with hypertrophic and dilated cardiomyopathy were elaborated by a computer-assisted 3D imaging technique. This technique showed good concordance with the results from cardiac catheterization or radionuclide ventriculography.

PTCA in elderly patients: acute results and long-term follow-up.
Acute results and long-term follow-up of percutaneous transluminal coronary angioplasty (PTCA) in 125 patients aged 75 to 90 years (79 men; 46 female; mean age 78 +/- 3 years), with mainly unstable angina (102 patients) are reported. Successful PTCA was achieved in 96 out of 108 patients (89%); occlusions could be reopened in eight out of 17 patients (47%). Thirty-eight procedures were multiple vessel or multiple lesion PTCA, so that the lesion-related success rate of PTCA was higher (91%). Major complications occurred in seven patients (5.6%) including one procedure-related death. In-hospital mortality was 3% and concerned exclusively patients with unstable angina and unsuccessful procedure. At a mean follow-up of 27 +/- 16 months (2 to 82 months) 13 additional patients had died: 10 from cardiovascular causes, three from cancer. In the meantime, three patients underwent non-fatal myocardial infarction and three elective bypass surgery; 26 patients had repeat PTCA. Eighty-seven of the 93 surviving patients with successful primary procedure and reintervention if necessary, were in anginal class I or II; only six were in class III. We conclude that the success rate of PTCA in elderly patients is comparable to that in younger patients, and that a successful procedure leads to continued relief of symptoms.

Percutaneous transluminal coronary angioplasty in patients with severely depressed left ventricular function.
Among nearly 2,000 consecutive percutaneous transluminal coronary angioplasty (PTCA) patients, 42 patients (36 male, 6 female; mean age 60 +/- 11 years) with mainly unstable angina had ejection fractions of < or = 35% (mean 30 +/- 5%). All patients had previous myocardial infarctions; 31 (= 74%) had multivessel disease. Successful procedure was achieved in 35 of the 42 (= 83%) patients, 31 of 35 (= 89%) stenoses could be successfully dilated and 9 of 15 (= 60%) occlusions reopened. In-hospital mortality was 2.4%. Follow-up angiography in 22 of the 35 patients who had been successfully treated showed significant improvement of ejection fraction from 29 +/- 5 to 36 +/- 7%. At clinical follow-up 19 +/- 14 months (2-53 months) after the procedure, nearly all surviving patients were in anginal class I or II, 5 had died from cardiac and 1 from noncardiac causes. Thus, PTCA in patients with severely depressed left ventricular function shows acceptable acute results; attenuation of ventricular dysfunction and continued symptomatic improvement can be achieved. However, late outcome is significantly worse than in patients with normal ventricular function.

[Benign tumors of the heart].
Benign tumors of the heart are rare and their symptomatology often remains ambiguous. Nevertheless, they are an important differential diagnosis of valvular heart disease, cardiac insufficiency, ventricular and supraventricular rhythm disturbances, conduction defects, syncopes, and arterial or pulmonary embolism. Furthermore, they can mimic an infective, malignant or immunological disease. For the first time, at the beginning of the 1950s, the clinically suspected diagnosis of a cardiac tumor was confirmed by angiocardiography; now, after the technical evolution of ultrasound, computer-tomography and nuclear magnetic resonance imaging over the past 30 years, the intravitam diagnosis is made more often and patients can be surgically treated.

[Recurrent myxoma].
In a now 53-year-old woman, who suffered from recurrent syncope and dizziness, a biatrial myxoma originating from the interatrial septum was resected nearly 4 years ago, and the resulting septal defect was closed by a Dacron patch. In the symptomless patient the recurrent myxoma was revealed by echocardiography. The left atrial myxoma was surgically removed without repeat heart catheterization. This case underlines the importance of regular, echocardiographic follow-up examinations in patients in whom a myxoma has been excised. In case of suspicious findings, an additional transesophageal examination or nuclear magnetic resonance imaging should be performed.
