Ligoniai ir metodai 1987–2007 metais Vilniaus širdies ligų klinikoje buvo atlikta 101 BPV, ligonių amžius nuo 1 paros iki – 39 metų. BPV atlikta esant spaudimo per PA vožtuvą skirtumui > 30 mm Hg. Ligoniai prieš BPV suskirstyti į dvi grupes pagal tai, ar pradinis spaudimo per PA vožtuvą skirtumas <50 mm Hg (1 gruoė), ar > 50 mm Hg (2 grupė). Analizuotas duomenų kitimas tiesiogiai po BPV, tarpiniu laikotarpiu (iki dvejų metų po BVP), vėlyvuoju laikotarpiu (praėjus daugiau kaip dvejiems metams). Ligoniai po BPV buvo suskirstyti į dvi grupes: turintys liekamąjį spaudimo skirtumą iki 36 mm Hg ir daugiau kaip 36 mm Hg. Rezultatai BPV atlikta 18 pacientų, kurių spaudimo per PA vožtuvą skirtumas < 50 mm Hg. Iškart po BVP spaudimo skirtumas per PA vožtuvą sumažėjo nuo 39,5 ± 5 iki 15,83 ± 8,37 mm Hg, tarpiniu laikotarpiu – iki 20 ± 6 mm Hg, vėlyvuoju – iki 21,5 ± 5 mm Hg. BPV atliktos 83 pacientams, kurių spaudimo per PA vožtuvą skirtumas > 50 mm Hg. Tiesiogiai po BVP vidutinis spaudimo skirtumas sumažėjo nuo 81,31 ± 21,28 iki 31,32 ± 13,82 mm Hg, tarpiniu laikotarpiu – iki 27,56 ± 12,71 mm Hg, vėlyvuoju – iki 19,89 ± 10,12 mm Hg. Esant liekamajam spaudimo skirtumui po BPV < 36 mm Hg (58 ligoniai), tarpiniu lakotarpiu vidutinis spaudimo skirtumas 23,66 ± 9,29 mm Hg, vėlyvuoju – 16,85 ± 7,98 mm Hg. Esant liekamajam spaudimo skirtumui po BPV > 36 mm Hg (21 ligonis), tarpiniu laikotarpiu vidutinis spaudimo skirtumas 51,99 ± 20,61 mm Hg, vėlyvuoju – 35,7 ± 16 mm Hg. Vėlyvuoju laikotarpiu spaudimo skirtumas mažėja, bet didėja PA nesandarumas. Tuoj po BPV nesandarumas nustatytas 7 %, tarpiniu laikotarpiu – 53 %, vėlyvuoju – 81,7 % ligonių. Išvados BPV yra gerai toleruojamas ir veiksmingas nechirurginis gydymo būdas. Daugumai ligonių išryškėja vėlyvasis nedidelis plaučių arterijos nesandarumas, kurį retai prireikia gydyti chirurginiu būdu. Mūsų studija rodo, kad tinkama ligonių atranka leidžia pasiekti gerų tiesioginių, tarpinius ir vėlyvųjų rezultatų.

Balloon pulmonary artery valvuloplasty – immediate, mid-term and long-term follow-up results: 20-year experience Sigitas Čibiras, Eugenijus KosinskasVilnius University Clinic of Heart and Vascular Medicine, Vilnius University Hospital Santariškių Klinikos, Santariškių str. 2, LT-08661 Vilnius, LithuaniaE-mail: [email protected] Background To analyze immediate, mid-term and long-term follow-up results after percutaneous balloon pulmonary valvuloplasty (BPV) of congenital pulmonary artery (PA) stenosis for a 20-year period. Patients and methods During 1987–2007, in the Vilnius Clinic of Heart Diseases 101 BPV were performed, the patients’ age range being 1 day – 39 years. BPV was performed with the primary PA valvular pressure gradient > 30 mm Hg. Patients before BPV had been divided into two groups: (1) with primary PA pressure gradient < 50 mm Hg; (2) with primary PA pressure gradient > 50 mm Hg. Data were analyzed immediately after BPV, in a mid-term (2 years) and a long-term (more than 2 years) follow-up. The same patients after BPV were divided into two groups: with residual pressure gradient < 36 mmHg and > 36 mmHg. Results Eighteen BPV were performed with the primary PA pressure gradient < 50 mm Hg: the immediate mean pressure gradient decreased from 39.5  ±   5 to 15.83 ± 8.37 mm Hg, in the mid-term period to 20 ± 6 mm Hg, and in the long-term to 21.5 ± 5 mm Hg. Eighty-three BPV were performed with the primary PA pressure gradient > 50 mm Hg; the immediate mean pressure gradient decreased from 81.31 ± 21.28 mm Hg to 31.32 ± 13.82 mm Hg, in the mid-term period to 20 ± 6 mm Hg and in the long-term period to mm Hg. With the residual pressure gradient after BPV < 36 mm Hg (58 patients), in the mid-term period the pressure gradient decreased to 23.66 ± 9.29 mm Hg and in the long-term period to 16.85 ± 7.98 mm Hg. With the residual pressure gradient after BPV > 36 mm Hg (21 patients), in the mid-term period the pressure gradient decreased to 51.99 ± 20.61 mm Hg and in the long-term period to 35.7 ± 16 mm Hg. In the long-term follow-up, the pressure gradient decreased, but PA regurgitation (PAR) was progressive. Immediately after BPV, PAR was seen in 7%, in mid-term follow-up in 53 %, and in long-term follow-up in 81.7 % patients. Conclusions BPV is a well tolerated and effective non-surgical treatment method. Late trivial PAR develops in the majority of cases, but rarely requires surgical treatment. Our study has demonstrated that the appropriate patient selection enables achieving good immediate, mid-term and long-term follow-up results.

INTRODUCTION: We previously reported the clinical outcomes of a large pediatric cohort with discrete subaortic stenosis (SubAS) 1 . While patients with more significant left ventricular outflow tract obstruction (LVOTO) at diagnosis progressed rapidly others with mild LVOTO at presentation showed little progression of obstruction or aortic insufficiency (AI). A limitation of our previous study was a relatively short follow-up period. OBJECTIVE: To extend the follow-up of our previously described cohort with SubAS. METHODS: Information was gathered retrospectively on 71 previously identified patients diagnosed with SubAS from 1985–1998. RESULTS: Current data was available on 61/71 patients. At diagnosis the average age was 5.2±0.5 years (mean±SEM), peak LVOT Doppler gradient (Echograd) was 30±3 mmHg, and AI (all mild) was present in 25%. At last assessment the average age was 15.7±0.4 years. Twenty patients were followed only medically and were last reassessed 9.2±1.0 years after diagnosis at 15.8±0.7 years of age. The mean Echograd was unchanged from diagnosis (19±2 vs. 19±3 mmHg). The incidence of AI on echocardiography (all mild) increased from 5% to 55% although none was detectable by auscultation. Forty-one patients underwent surgery 3.0±0.5 years after diagnosis at 7.4±0.6 years of age. The Echograd at diagnosis was 35±3 and increased to 61±6 mmHg pre-operatively. Ten patients were re-operated 5.7±0.7 years after the first surgery and 2 patients had a second re-operation. The last follow up of the operated patients occurred at 15.7±0.6 years of age. At that time the Echograd was 16±3 mmHg and the incidence of AI by echocardiography had increased to 98% (36 mild & 3 moderate) but was evident on auscultation in only 25%. CONCLUSIONS: This study represents the largest and longest contemporary follow-up of pediatric patients with discrete SubAS. Our results indicate that some patients with SubAS show significant LVOTO at diagnosis and subsequent progression. Surgery in these patients provides good relief of LVOTO but does not eliminate AI. The one third of patients presenting with mild LVOTO and AI show little progression through childhood and adolescence. We suggest that the latter can be safely followed medically. 1) Rohlicek et al.
