[Clinical and haemodynamic results after repeat valvotomy of the mitral valve using the Inoue balloon. A comparison with the results after primary valvotomy]. / Klinische und hämodynamische Ergebnisse nach Re-Valvotomie der Mitralklappe mittels Inoue-Ballon. Ein Vergleich zu Ergebnissen nach primärer Valvotomie.

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.

[Aortic isthmus stenosis with open ductus Botalli as etiology of severe heart failure in a 36-year-old patient--case report of successful surgical treatment]. / Aortenisthmusstenose mit offenem Ductus Botalli als Ursache einer schweren Herzinsuffizienz bei einer 36-jährigen Patientin--Fallbericht über eine erfolgreiche operative Behandlung.

We report on the history of a 36-year-old woman with untreated coarctation of the aorta and patent ductus arteriosus who developed refractory heart failure due to severely impaired left ventricular function. After coarctation repair and duct resection, left ventricular function improved to normal. Even in the presence of longstanding left ventricular pressure and volume overload, subsequent severe myocardial failure may be reversible by surgical repair.

Moraxella catarrhalis endocarditis: report of a case and literature review.

A 53-year-old man developed severe acute systemic illness three weeks after an upper respiratory tract infection. Serial blood cultures grew Moraxella catarrhalis. During antibiotic treatment, fever and infectious parameters disappeared, but severe aortic regurgitation developed. Aortic valve replacement was performed, during which extensive destruction of the aortic valve was noted. Endocarditis due to M. catarrhalis is very rare with, to our knowledge, only six cases having been reported to date. M. catarrhalis is a normal commensal of the upper respiratory tract, but in unpredictable circumstances can become an important pathogen. Bacteremia due to this organism therefore requires prompt treatment, as serious organ complications, including endocarditis, can occur.

Small ventricular septal defects in adults.

AIMS: To establish the frequency of complications in adults with small ventricular septal defects, which have not undergone surgery. METHODS AND RESULTS: One hundred and eighty-eight adults aged 17-72 (mean, 29.2) years with a small ventricular septal defect were studied. They were referred to a national cardiac centre (National Heart Hospital) and specialized grown-up congenital heart unit. One hundred and thirty-eight were examined in 1994-95. Fifty patients (26.6%) had additional cardiovascular lesions, most commonly a bicuspid aortic valve and/or coarctation. Spontaneous closure occurred in 19 (10%) between the age of 17 and 45 (mean, 27) years. Twenty-one (11.2%) had infective endocarditis. Aortic regurgitation developed in 37 (19.7%) patients; it was severe in nine. Atrial arrhythmias (supraventricular tachycardia or atrial fibrillation) occurred in 12 patients. In four patients, atrial fibrillation produced severe right-sided congestion with a left ventricular to right atrial shunt and haemodynamic features suggesting 'restrictive cardiomyopathy'. Four patients had ventricular arrhythmia. Disproportionate left ventricular enlargement on echocardiography and/or chest radiography was present in 26 (13.8%) without lesions to account for it. CONCLUSIONS: Eighty nine patients (47%) aged 17-44 (mean, 26.8) years had no complications through many years, while spontaneous closure occurred in 19 (10%) during adulthood. Forty-six (25%) had serious complications: infective endocarditis (11%), progressive aortic regurgitation (5%), age-related symptomatic arrhythmias (8.5%) and atrial fibrillation the commonest. Accepting that there may be a referral bias for those with complications, the course of a small ventricular septal defect is not necessarily benign during adult life.

Outcome of pregnancies in patients with complex pulmonary atresia.

OBJECTIVE: To evaluate the outcome of pregnancies in patients with complex pulmonary atresia, comparing those with and without previous radical surgical repair. DESIGN: A retrospective study of all pregnancies in women with complex pulmonary atresia registered on the Grown-up Congenital Heart Unit database between 1977 and 1994. SETTING: Referral centre for adolescents and adults with congenital heart disease. PATIENTS: Forty one pregnancies occurred in 15 patients. They were divided into two groups; group I, 26 pregnancies in nine patients before radical repair (cyanotic); group II, 15 pregnancies in seven women after radical surgical repair. RESULTS: In group I there were three terminations, 13 miscarriages, eight healthy children, and two neonatal deaths. Five children were born prematurely and all had low birthweights. In group II there were two miscarriages, 11 normal children, and two children with congenital heart disease. None was premature and all had normal birthweights. There were major complications in both groups: in group I there were two thromboembolic complications and one episode of heart failure; in group II there was one pulmonary embolism and one arrhythmic complication, five pregnancies in three patients were complicated by left ventricular failure that was persistent in one case and progressive in another, leading to death 13 months after delivery. CONCLUSIONS: Patients with complex pulmonary atresia, with or without surgical repair, who have no or mild symptoms, can have successful pregnancies. Surgical repair decreases fetal complications significantly. In both groups thrombotic disorders and heart failure must be prevented. Patients with residual systemic-pulmonary collaterals after surgical repair are particularly at risk of left ventricular failure.
