I thinlunga he ‘pocket’ te tak te hi i hria em? – Atrial Appendage veilam a awm

Kan thinlung hi taksa peng mak tak a ni tih kan hre vek. Mahse he thinlung peng te te thenkhat hi kan sawi vak lo a ni lawm ni? Awle, vawiin hian i hriat tam loh pawh nise, mahse pawimawh tak ni thei tur tlemte kan sawi dawn a ni. Chu chu "Left Atrial Appendage" emaw, Mizo tawngin `(Left Atrial Appendage)` emaw, a tawi zawngin `(LAA)` kan ti ang. Ngaihtuah buai suh, hei hi hriatthiam awlsam tak a ni.

Hei hi Left Atrial Appendage hi eng nge ni?

A awlsam zawngin LAA hi i thinlung veilam chamber chunglam, veilam atrium inzawmkhawmtu, taksa ruh nei sac te tak te a ni. I kawr chhunga pocket te tak te ang maiin ngaihtuah rawh.

LAA hi sawiho a ni fo a, a bik takin thinlung natna thenkhat nei, Atrial Fibrillation (thinlung thawk mumal lo, Afib tia hriat bawk) te tan chuan doctor-te chuan stroke hlauhawmna tihziaawmna turin LAA kha khar, paih emaw, block emaw an rawt thin. Hei hi a chhan chu Afib vei te thinlunga thisen zam lo awm tam zawk hi he bawm te tak te LAA an tih ah hian a lo awm thin a ni.

Mahse hetah hian a pawimawh ber chu hlauhna tur i nei lo . A chhan chu he `(LAA)` hi i thinlungin a nitin hna a thawh that theih nan a pawimawh lo. Chumi tel lo chuan thinlung hian hna a thawk tha thei hle.

Left atrial appendage (LAA) hi engtin nge a awm? A hnathawh chu eng nge ni?

He LAA te tak te hian hna danglam tak a nei bawk. A hnathawh ber chu thinlung chhunga thisen awm zat, a nih loh leh thisen volume enkawl tura puih hi a ni. Engtin nge i hriat?

I thinlunga thisen lut tam lutuk, leh he `(LAA)` bangte a inzawm chuan thisenah hian protein chi khat bik `(Natriuretic Peptides)` an tih chu a chhuah chhuak thin. Kan taksaa signaling system tlemte ang maiin han ngaihtuah teh. Heng chemical messenger `(Natriuretic Peptides)` tia koh te hian thisen a pun chuan kal (kidney) ah kal in, "Awle, tunah chuan taksa hian chi leh tui tlem a nei tam lutuk a, a then chu zun nen i chhuah tir ang u," an ti thin. Tin, hengte hian thisen kalna kawngte chu a ti hahdam deuh a, pipe tight tlem a tihzauh ang maiin. Tichuan thisen chu awlsam zawkin a luang thei a, thisen sang pawh a tlahniam bawk.

Tunah chuan i ngaihtuah mai thei, heng `(LAA)` level te hi surgery hmanga kan paih emaw, kan block emaw chuan engtin nge an awm ang? A tlangpuiin, chutiang thil tih hnuah chuan heng `(Peptide)` level te hi thla thum vel chu a danglam deuh thei. Mahse, chutah chuan an dinhmun pangngaiah an kir leh ta a ni.

Thil dang pakhat chu thisenah `(Natriuretic Peptides)` level a san lutuk hian a chang chuan `(Heart Failure)` ang chi (thinlung natna ni lo, thinlung hnathawh chak lohna) ang chi natna lanchhuahna a ni thei bawk. A chhan chu chutih hunah chuan taksa chuan tui tam zawk chu paih chhuah a tum a, a chhan chu thinlung hian thisen tam zawk chu a khawih harsat avangin.

He `(LAA)` hi khawiah nge a awm? Eng ang nge a nih?

Awle, tunah chuan he `(LAA)` hi thinlung chhungah khawiah nge a awm tak tak tih i en ang u. I thinlung left atrium (upper left chamber) leh left ventricle (lower left chamber) inkar canal ang chi hmun te tak teah a awm a ni. A tam zawkah chuan left ventricle chung lamah emaw, `(Main Pulmonary Artery)` chungah emaw a awm a, chu chu thinlung atanga lung thlenga thisen phurtu main channel a ni. Tin, thinlung dang ang bawkin he `(LAA)` pawh hi `(Pericardium)` chhungah a awm a, chu chu thinlung hualtu bawm ang maia invenna khuhna a ni.

Part lam hawi chuan LAA hi thisen kalna kawngkhar, leh taksa peng inzawmkhawm thei atanga siam bawm a ni. He kawngkhar atang hian thisen a luang lut leh chhuak thin.

A lian zawngah chuan LAA hi a tlangpuiin millimeter 46 vel (inches 2 aia tlem lo) a sei a ni. Mahse mi thenkhat chu millimeter 27 atanga 60 thlenga sei an ni thei. I credit card sir te tak te angin ngaihtuah rawh. He bag te tak te hian thisen milliliter 9 vel (teaspoon hnih vel) a keng thei a ni. LAA hmui, a nih loh leh a hawnna chu oval a ni tlangpui. Mahse mi thenkhat chu round emaw, shape dang nei emaw an ni thei.

`(LAA)` hi chi hrang hrang a awm em? Eng emaw nghawng an nei em?

Ni e, mak tak maiin mi zawng zawng `(LAA)` hi a pianzia inang vek a ni lo. Kan kutziak ang bawkin a pianzia a inang lo. A tlangpuiin `(LAA)` hian a then te te pahnih emaw pathum emaw a nei a, chu chu `(lobes)` an ti a. Mahse mi thenkhat chuan lobe pakhat chauh an nei thei a, thenkhat erawh chuan pali emaw a aia tam emaw an nei thei thung. Hriat chi hrang hrang (main recognized shape) tlemte a awm a:

• Chicken wing shape: Hei hi a lan dan tlangpui a ni. Main lobe lai takah hian bend tlem a awm a. Hetiang pianzia nei te hi stroke vei an tlem zawk niin an sawi .
• Cactus lem: Hei hian central main petal a nei a, a petal dangte chu a chhuak niin a lang.
