Mitral vharafu insufficiency

Mitral vharafu insufficiency yakakonzerwa kukanganisika iri wokugumisa ishande. Pane kunetswa nokuda deformation ari ichibhabhamisa Kazhinji fibrous hunhu. Impact pamusoro pokumuka chirwere vane maronda subvalvular zvivako, uyewo kutendeka zvimwe kusagadzikana vharuvhu zvinhu. Zvinokoshawo ndezvokuti ndiye dilatation mu anulus fibrosus. Zvose pamusoro zvinoisa pakupedzisira kuti kudzoka kwebasa ropa kubva ventricle rworuboshwe kupinda akasiya atrium systole, zvichikonzera zvinoderedza kweminiti kweropa uye kukura pulmonary neBP.

Kukundikana of mitral vharuvhu dzoga hunhu ndorwevaya isingawanzowanikwi chaizvo chinoshamisa. Ezvinhu akadaro anotaurwa muzana zviviri chete vose nyaya. Kazhinji, kutyora mukuvhara basa iri pamwe stenosis of mitral vharuvhu kana kutsemuka mwoyo kuremara.

Mamiriro anogona chadzo kana makemikari hunhu.

Muchiitiko chokutanga, kukundikana mitral vharuvhu anova panguva kuwedzera Vhoriyamu rworuboshwe ventricle ari somugumisiro myocardial zvirwere. zvirwere zvakadai kutsamwisa paumbwe hemodynamic zadzisa mwoyo tsandanyama dhipatimendi.

Mhaka iri mhando kufoira angava autonomic dystonia uye papillary tsandanyama matauriro rutapudzo.

Zvinofanira kucherechedzwa kuti dzichipfekeka chirwere haana chokuita nezvirwere mwoyo.

Kushaya Organic zvakaita mitral vharuvhu kunoitika pamusana anatomical lesion kana nemarunda shinda yacho zvakananga pachake.

The chirwere chinogona semhosva chakasimba kana chirwere.

Muchiitiko chokutanga kukundikana iri migumisiro kukuvara mhete wayo paumbwe imwe mota iri pakanyorwa infective endocarditis kana kukuvara (kunyanya pakuvhiya). Uyezve, mhosva rikwanise chirwere kuve aibuda ichibhabhamisa akaperera kukanganisa sezvo pamusana perforation kana kuparadzwa, atrial myxoma.

kuwedzera kwakadaro chirwere uye kunoratidzwa dysfunction kana kuvadza papillary netsandanyama.

Zvirwere unomuka pamusoro anogumbura (scleroderma, rheumatic fivha, chinonzi systemic lupus erythematosus) uye chinopedza (calcification pamusoro annulus fibrosus, Ehlers-Danlos Syndrome uye Marfan vake, pseudoxanthoma) kuchinja. Simba chokuziva uye Genesisi. Nokuti zviitiko izvozvo zvinofanira vachinzi fibroelastosis endocarditis, transposition midziyo mukuru, anomaly kukura kuruboshwe coronary tsinga. Chirwere kukundikana ndepana kukanganisa batanidzo panguva fetus primordia inotungamirwa vharafu. Somugumisiro, hapana remubatanidzwa endocardial pamakusheni. Myxomatous degeneration of mitral vharuvhu (ichibhabhamisa ayo) riri kukura chirwere chimiro.

Chokwadi, kutyora wokugumisa basa anogona kukonzerwa uye STRUCTURAL kuchinja. Vanoratidza, kazhinji pane hypertrophic cardiomyopathy, zororo chords or the nemarunda (zvinoguma yechipiri myocardial infarction, prolapse, traumas, uyewo kwatangwa) paraproteznoy fistula anomuka nokuda kuputika sutures.

Chirwere kukundikana kungakonzerwa infective endocarditis, yakaumbwa muna womunyika kana prosthetic vharafu.

Zvichienderana kwokuomerwa regurgitation muri madhigirii matatu.

First - unexpressed - kunoratidzwa nokuda vasabatwa ropa kudzoka chikumbiro chete panguva vharuvhu. Kana simba wechipiri vakachengeta mwero kuwedzera atrium. Saka postback manyorerwo aro pakati chikamu.

In dhigirii wechitatu pane wandei dilatation. Saka reguritatsii ano vanogona kusvika rwemberi munharaunda rusvingo atrium kuruboshwe.
