Advanced Therapy in the Treatment of Pulmonary Arterial Hypertension in Adult Congenital Heart Disease

Authors:

Abstract

Pulmonary arterial hypertension (PAH) is a severe chronic, progressive disease. It affects the group of patients with congenital heart diseases (CHD); a high-profile example is Eisenmenger’s syndrome, the CHD with the greatest mortality and morbidity. Advanced PAH treatment for adult congenital heart diseases (ACHD) has significantly improved the outcome and clinical course for these patients, and endothelin receptor antagonist, primarily bosentan, are recommended as first-line treatment today. All case studies and registries show that bosentan improved the exercise tolerance, reduced pulmonary vascular resistance, and decreased the mortality of these patients. Other advanced therapy drugs (phosphodiesterase inhibitors and prostaglandins) are added in case of disease progression. Advanced PAH therapy can be administered long-term with good results and few side effects. Apart from Eisenmenger’s syndrome, other patients from the PAH group in ACHD can be treated through advanced therapy. In the treatment of surgical patients with ACHD who have developed or are developing a subsequent PAH, a different double endothelin inhibitor is indicated, macitentan. Therapy through a combination of drugs has not led to any further significant improvements in relation to treatment by a monotherapy of endothelin receptor inhibitors. It is possible that patients with Fontan circulation will be the target group for the treatment with these drugs.

Uvodnik Editorial
S
velikim sam zadovoljstvom prihvatila biti
gost urednik ovoga broja časopisa
Cardio-
logia Croatica
. Broj je posvećen prirođenim
srčanim bolestima odraslih. Već je nekoliko puta
u ovom časopisu bilo riječi o toj temi sa stajališta
epidemiologije i organizacije1,2, a u ovom bih se
uvodniku osvrnula na neke druge teme te upo-
znala hrvatsku kardiološku javnost s određenim
napretkom koji smo postigli u kratkom vremenu
u kojemu je problem odraslih bolesni ka s prire-
nim bolestima srca u Hrvatskoj osviješten.
Akronim
. U svrhu lakšeg razumijevanja, u li-
teraturi koja je uglavnom engleska, pojavljuju
se dva akronima za kongenitalne srčane bolesti
odraslih, a to su GUCH (
grown up congenital he-
art disease
), više rabljen u Sjedinjenim Država-
ma, i ACHD (
adult congenital heart disease
), koji
prevladava u Engleskoj, odnosno Europskoj uni-
ji. Razmišljajući koji bi akronim bio prihvatljiv u
hrvatskom jeziku, pri osnivanju Radne skupine
za prirođene srčane bolesti Hrvatskoga kardi-
ološkog društva, na sjednici Upravnog odbora,
raspravljali smo o toj temi i suglasili se s prijedlo-
gom PSBO (prirođene srčane bolesti odraslih). O
tom prijedlogu očekujemo širu raspravu te će to
biti i tema okruglog stola na našemu sljedećem
nacionalnom kongresu. Radi jednostavnije ko-
munikacije u ovom ćemo broju rabiti taj akronim.
Referalni centar
. S obzirom na preporuke, kako
smjernica3, tako i općeg konsenzusa stručnjaka
iz tog područja, ovom prilikom upoznali bismo
čitatelje s činjenicom pokretanja postupka osni-
vanja nacionalnog centra za zbrinjavanje bole-
snika s PSBO-om u Kliničkom bolničkom centru
Zagreb zato što ta ustanova za sada jedina ima
sve elemente potrebne za multidisciplinarni pri-
stup takvim bolesnicima. Prema broju stanovni-
ka, Hrvatska ih može očekivati 5 10 tisuća te
It was a great pleasure to accept the invita-
tion to be the guest editor for this issue of
Cardiologia Croatica
, which is dedicated to
congenital heart disease in adults. This topic
has been touched upon several times already
in the journal from the organizational and epi-
demiological perspectives1,2. In this editorial, I
would like to address other topics and inform
the general cardiologic public in Croatia about
some progress achieved over a short span of
time in increasing awareness of the problem of
adult patients with congenital heart disease.
Acronym
. For easier comprehension, two ac-
ronyms are generally used in the predominantly
English language literature: GUCH (grown-up
congenital heart disease), more common in the
USA, and ACHD (adult congenital heart disease),
more common in the UK and European Union.
While deliberating on the best acronym to use
in the Croatian language during the formation of
the Working Group for Congenital Heart Disease
of the Croatian Cardiac Society, we discussed this
topic at the meeting of the Management Board
and agreed on the acronym PSBO (“prirođene
srčane bolesti odraslih” congenital heart dis-
ease in adults). We expect more discussion on
this topic and that this will be one of the points
addressed at the round-table meeting at our next
national congress. For easier comprehension, the
Croatian language version of this Journal’s issue
will be using PSBO as an acronym.
Referral Center
. Given the recommendations in
relevant guidelines3 as well as from the general
consensus of experts in this eld, we would like
to announce the beginning of efforts to found a
national care center for patients with ACHD at the
University Hospital Centre Zagreb, since this in-
stitution is currently the only one with all the ele-

će imati potrebe za jednim do dva takva centra. U kratkome
članku u ovom broju opisana su glavna obilježja ovakvog cen-
tra, a posebno treba naglasiti da bi se svi bolesnici s PSBO-om
trebali registrirati u njemu, obaviti prvu evaluaciju, a da će se
većina nastaviti liječiti u loka lnim ustanovama, osi m u sluča-
ju iznimne kompleksnosti ili iznimnih situacija.
Registar
. Veoma je važno i osnivanje registra. I iz drugih
područja kardiologije znamo koliko nam nedostaju nacional-
ni podatci, i ne jednom smo o tome raspravljali (registar akut-
noga koronarnog sindroma, registar perkutanih koronarnih
intervencija i sl.). S obzirom na relativno ograničen broj bo-
lesnika s PSBO-om, pruža nam se jedinstvena prilika da prvi
put u Hrvatskoj imamo pravi registar, a u ovoj kategoriji on
je veoma važan, jer je riječ o tzv. cjeloživotnim pacijenatima,
koji se međusobno razlikuju unatoč možda istoj dijagnozi i u
kojih je i sama bolest, ali i liječenje kompleksno. Registar bi
svima koji dolazimo u dodir s njima znatno olakšao među-
sobnu komunikaciju i liječenje. Unatoč velikome trudu regi-
star, koji vodimo u KBC-u Zagreb nešto više od godinu dana,
za sada obuhvaća tek nešto više od 350 bolesnika. Nadamo se
da će ovaj, tematski broj potaknuti razmjenu podataka.
Edukacija
. Opće je poznato da su kardiolozi slabije obrazo-
vani kada je posrijedi prirođena srčana bolest jer je većina
nas educirana u vrijeme kada je potreba za liječenjem ova-
kvih bolesnika bila mala. Iako kasnimo za razvijenim ze-
mljama u zbrinjavanju bolesnika s PSBO-om, isti je problem
prisutan i tamo te se u smjernicama4, ali i u raznim članci-
ma govori o kurikulu obrazovanja kadiologa supspecijalista
za PSBO. Smatramo da je važno da neki naši kolege završe
edukaciju koju preporučuje Europsko kardiološko društvo , ali
je još važnije da svi mi postanemo svjesni problema da takve
bolesnike prepoznajemo, da ih pravilno usmjerimo te da se
dalje brinemo za one niže ili srednje kompleksnosti, pružajući
im potrebnu razinu skrbi, bilo u svojoj ustanovi bilo upućujući
ih u specijalizirani centar za PSBO. Kao mali doprinos u po-
stizanju tog cilja željeli smo izdati i tematski broj časopisa.
U ovom su broju tiskani članci koji sadržavaju teme izne-
sene na I. sastanku Radne skupine za PSBO Hrvatskoga kar-
diološkog društva, održanom 12. studenoga 2015. u Hrvatskoj
kući srca u Zagrebu, uz neočekivano veliki interes te sa zado-
voljstvom mogu istaknuti da je dvorana bila puna tijekom ci-
jeloga jednodnevnog sastnaka. Nadamo se da će teme iz ovog
broja časopisa

zainteresirati čitatelje, a
iznesene su kao pregledni članci, prikazi slučajeva i stručni
članci te da će prenijeti informacije i poruke koje smo tijekom

ments needed for a multidiscipli nary approach to these patients.
Based on demographics, Croatia can be expected to have 5-10
thousand such patients, and will need one or two such centers.
A brief article in this issue describes the main characteristics of
such a center. It is especially important to note that all patients
with ACHD should register and receive the rst evaluation at the
center, after which they wil l continue treatment in t heir local in-
stitutions except in extremely complex or extraordinary cases.
Registry
. Establishing a patient registry is very important
as well. Other cardiologic issues have shown how badly we
lack national data, a problem that has been discussed sev-
eral times (acute coronary syndrome registry, percutaneous
coronary intervention registry, etc.). Due to the relatively lim-
ited number of patients with ACHD, we are presented with a
unique opportunity to create a real registry for the rst time in
Croatia, which is especially important for ACHD, since these
are “lifelong” patients with a complex disease that requires
complex treatment due to differences in clinical presentation
even under the same diagnosis. A registry would signicantly
improve communication among all physicians coming into
contact with these patients. Despite great effort, the registry
currently contains just over 350 patients we have had at the
University Hospita l Centre Zagreb for over a year. It is our hope
that this issue of our Journal will encourage data-sharing.
Education
. It is well known that cardiologists lack education
on congenital heart diseases, since most of us received our de-
grees at a time when the need for treatment of these diseases
was small. Although we are behind other countries in the or-
ganization of care for patients with ACHD, the same problem
is present in those countries as well, and guidelines4 as well as
other articles discuss the need for the education of cardiolo-
gists, subspecialists for ACHD. We believe it is important that
some of our colleagues complete courses recommended by the
European Society of Cardiology, but that it is even more impor-
tant that we all become aware of the problem, recognize the
patients, advise them appropriately, and treat cases of lower or
moderate complexity by providing them with an adequate lev-
el of care either in our own institutions or by sending them to
specialized ACHD centers. As a small contribution to this goal,
we decided to dedicate this Journal issue to that topic.
This Journal issue contains articles addressing topics dis-
cussed at the 1st meeting of the ACHD Working Group of the Croa-
tian Ca rdiac Society, which took place in the Croati an Heart House
in Zagreb on November 12, 2015 and was met with great interest. I
can say with plea sure that the conference hall w as full during t he
whole one-day meeting. We hope that readers will nd the topics
addressed in this issue of
Cardiologia Croatica
to be interesting
reading; they are presented as review articles, case reports, and
professional articles and are intended to convey the information
and conclusions we arrived at during the meeting.

Article
Full-text available
The European Society of Cardiology (ESC) has recently published practice guidelines for the management of grown-up congenital heart disease (GUCH).1 For the sake of space, this document did not include recommendations for the organization of care for adults with congenital heart disease (CHD) nor for training in the subspecialty of adult CHD, although emphasis was given to their importance and the need for a separate recommendations paper in the future.1 This publication is a position paper from the ESC Working Group on Grown-up Congenital Heart Disease, which makes recommendations for the standards and organization of care for adults with CHD, as well as for training in GUCH within Europe. Obviously, there is a lack of solid scientific data to support such recommendations and the majority of them must remain based on expert consensus. The remarkable improvement in survival of surgically and interventionally treated patients with CHD has led to an increasing number of GUCH patients, in particular those with more complex disease. There are also patients with newly diagnosed CHD lesions in adulthood such as atrial septal defect, coarctation of the aorta, Ebstein's anomaly and congenitally corrected transposition of the great arteries. The 32nd Bethesda Conference report in 20012 estimated that there were ∼2800 adults with CHD/million population, with more than half having moderate or highly complex disease. More recently, Marelli et al .3 reported a prevalence of 4090/million adults in Quebec for the year 2000 with 380 having severe disease. In Europe, we are currently faced with an estimated GUCH patient population of ∼2.3 million, which significantly outnumbers the paediatric CHD population of ∼1.9 million patients.4 There is general agreement that GUCH patients have very special needs and therefore physicians responsible of their care need specific expertise and training.1–11 It is …

Due to the growing number of patients with adult congenital heart disease (ACHD), although their exact number and distribution in Croatia is not yet known, monitoring and treating these patients in specialized centers has become a necessity. Their number is estimated at 12 000, and in most cases these patients will require one or more surgical procedures due to complications later in life. The recommendations of the European Society of Cardiology include guidelines on the necessary number of specialized centers and their organization. Organization of such a center has begun in the Zagreb Clinical Hospital Center. This article describes the first steps being taken, which include setting up a clinic for ACHD, regular multidisciplinary councils, formation of a patient registry, and first steps towards educating the cardiologic community. A large number of patients were examined in the Center recently, providing insight into the specific problems in this patient population; we will present three cases here. The first is a woman with a surgically repaired tetralogy of Fallot but with an improperly diagnosed and treated case of arrhythmia, which can lead to serious clinical deterioration. The second patient is a woman with a case of corrected transposition that went undiagnosed due to a lack of experience on part of the cardiologist. Although the patient has not experienced significant difficulties, they are expected in the future, making a correct diagnosis extremely important. The third case is a typical ACHD patient, a woman that had undergone numerous surgeries in childhood in a constant search for a long-term solution, which in this case was a non-surgical valve replacement at aortic position. This overview also outlines specific challenges faced when treating young people who put especially high value on the quality of life.
