Surgical treatment of aortic coarctation in adults: Beneficial effect on arterial hypertension
Background: The aim of this study was to determine the outcome after surgical repair of
aortic coarctation in adults, analysing its effect on arterial blood pressure.
Methods: Twenty-five adults (9 women, 16 men), mean age 43.4 years (19 to 70 years), underwent
aortic coarctation surgical repair. All patients suffered from preoperative hypertension. Mean
blood pressure was 182/97 mm Hg. Sixteen (64%) patients demonstrated reduced load capacity.
Operative technique was resection and end-to-end anastomosis for 5 patients (20%), interposition
of a Dacron-tube graft for 3 patients (12%), Dacron-patch dilatation was performed in 7 (28%)
patients, and in 10 (40%) patients we performed an extra-anatomical bypass graft.
Results: Early mortality occurred in 1 patient (4%). The mean blood pressure was reduced
[systolic 182 mm Hg vs. 139 mm Hg (p < 0.001), diastolic 97 mm Hg vs. 83 mm Hg (p < 0.001)]
in all patients. In 12 patients, blood pressure normalized immediately after surgery, in
7 patients it remained slightly elevated (systolic blood pressure between 140-160 mm Hg), and
1 patient suffered from prolonged arterial hypertension. Preoperatively, all patients were treated
with antihypertensive drugs. Eleven of 20 patients received long-term medication during follow-
up. In the remaining 4 patients, medication lists were unobtainable in retrospect. The
mean follow-up was 7.1 years (min. 1.0 years; max. 16.6 years). One patient (5%) died from
cardiac failure 12.4 years after the operation. On average, the New York Heart Association
(NYHA) class was improved by 0.92.
Conclusions: The surgical repair of aortic coarctation in adults can be performed with low
surgical risk. Surgery reduces hypertension and permits more effective medical treatment
Cardiac myxomas: Short- and long-term follow-up
Background: Cardiac myxomas are the most frequently encountered benign intracardiac
tumors, that, if left untreated, are inexorably progressive and potentially fatal. Patients with
cardiac myxoma can be treated only by surgical removal. This study summarizes our experience
over 22 years with these tumors.
Methods: Fifty seven patients (M/F: 14/43, age: 57.9 ± 14.6 years) with cardiac myxomas
underwent surgical resection at our institution. There were 82.4% left atrial myxomas, 14.0%
right atrial myxomas, 3.6% biatrial myxomas. The duration of symptoms prior to surgery
ranged from 6 to 1,373 days (median 96 days). The surgical approach comprised complete
wide excision. The diagnostic methods, incidence of thromboembolic complications, valve
degeneration, surgical repair techniques, recurrence and re-operation were reviewed and the
Kaplan-Meier survival curve was calculated.
Results: There were no in-hospital deaths. Hospital stay amounted to a mean of 13.7 ± 6.9 days.
Late follow-up was available for 54 (94.7%) patients for a median 7.5 years after surgery
(23 days to 21.4 years). Fifty two patients are alive, while five patients had died after a mean
interval of 6.3 years. Cause of death was cardiac in 40% of the patients (n = 2) and non-cardiac in the other 60% (n = 3).
Conclusions: Surgical excision of cardiac myxoma carries a low operative risk and gives
excellent short-term and long-term results. Surgical excision of the tumor appears to be curative,
with few recurrences at long-term follow-up. After diagnosis, surgery should be performed
urgently, in order to prevent complications such as embolic events or obstruction of the
mitral orifice. Follow-up examination, including echocardiography, should be performed
regularly
Chirurgiczne leczenie koarktacji aorty u doros艂ych - korzystny wp艂yw na nadci艣nienie t臋tnicze
Wst臋p: Celem badania by艂a ocena chirurgicznej korekcji koarktacji aorty u doros艂ych,
z analiz膮 jej wp艂ywu na ci艣nienie t臋tnicze.
Metody: Dwadzie艣cia pi臋膰 os贸b doros艂ych (9 kobiet, 16 m臋偶czyzn, 艣redni wiek 43,4 roku
19.–70. r偶.) przeby艂o chirurgiczn膮 korekcj臋 koarktacji aorty. U wszystkich chorych przed operacj膮
obserwowano nadci艣nienie t臋tnicze. 艢rednie ci艣nienie t臋tnicze wynosi艂o 182/97 mm Hg.
U 16 os贸b (64%) stwierdzono zmniejszon膮 wydolno艣膰 wysi艂kow膮. Zastosowana technika operacyjna
obejmowa艂a resekcj臋 miejsca zw臋偶enia i zespolenie „koniec do ko艅ca” u 5 chorych
(20%). U 3 pacjent贸w (12%) wszczepiono pe艂n膮 dakronow膮 protez臋 naczyniow膮. Operacj臋 poszerzenia
z u偶yciem 艂aty dakronowej wykonano u 7 (28%) os贸b, a u pozosta艂ych 10 (40%) chorych
wszczepiono ekstraanatomiczny pomost omijajacy miejsce zw臋偶enia cie艣ni aorty.
Wyniki: Wczesna 艣miertelno艣膰 oko艂ooperacyjna dotyczy艂a 1 chorego (4%). 艢rednia warto艣膰
ci艣nienia t臋tniczego zosta艂a zredukowana [ci艣nienie skurczowe 182 mm Hg v. 139 mm Hg
(p < 0,001), ci艣nienie rozkurczowe 97 mm Hg v. 83 mm Hg (p < 0,001)] u wszystkich
pacjent贸w. U 12 chorych ci艣nienie t臋tnicze uleg艂o normalizacji natychmiast po zabiegu chirurgicznym,
u 7 pozosta艂o nieznacznie podwy偶szone (ci艣nienie skurczowe 140-160 mm Hg), a u 1 chorego
nadci艣nienie t臋tnicze utrzymywa艂o si臋 d艂ugotrwale. Przed operacj膮 wszystkich pacjent贸w leczono
za pomoc膮 preparat贸w przeciwnadci艣nieniowych. Spo艣r贸d 20 pacjent贸w, kt贸rzy byli obj臋ci
d艂ugotrwa艂膮 obserwacj膮 pooperacyjn膮 (follow-up), 11 chorych wymaga艂o przeciwnadci艣nieniowego
leczenia farmakologicznego. Czterech chorych z powodu zmiany miejsca zamieszkania
by艂o nieosi膮galnych. 艢redni okres obserwacji wynosi艂 7,1 roku (min. 1 rok; maks. 16,6 roku).
Jedna osoba zmar艂a w p贸藕nym okresie pooperacyjnym z powodu niewydolno艣ci serca 12,4 roku
po operacji. Klasa NYHA poprawi艂a si臋 艣rednio o 0,92.
Wnioski: Chirurgiczn膮 korekcj臋 zw臋偶enia cie艣ni aorty u doros艂ych mo偶na przeprowadzi膰 przy
niskim ryzyku operacyjnym. Operacja redukuje nadci艣nienie t臋tnicze i pozwala zmniejszy膰 liczb臋
stosowanych preparat贸w przeciwnadci艣nieniowych
